Reach followingly in conjunction with the accompanying drawings, concerning the people who is familiar with this technology, will more easily demonstrate above-mentioned achievement of the present invention and relevant purpose and advantage and characteristics for finer description of the present invention.
Fig. 1～Fig. 5 is the block diagram with the present invention's corresponding TV list message transmission and application system.
Fig. 6～Figure 25 is that the diagram of the message format that uses in the system of Fig. 1～Fig. 5 is described.
Figure 26～Figure 60 is that the diagram of the data structure, flow process and the display format that use in the system of Fig. 1～Fig. 5 is described.
Turn to accompanying drawing, particularly Fig. 1～Fig. 4 now, show TV list message transmission and application system 50A～50D.System 50A～50D transmits TV catalog (catalogue) and the network control message such as packets of information that link via video blanking interval (VBI) line in for example various TV programme suppliers' 51 such as PBS, MTV or Showtime the TV signal.Subscriber unit 52 by Star Sight company obtains these data and is used to constitute an internal database.This internal database can be by subscriber unit 52 accesses, so that show a TV list that is received by user's TV for passage.
Because the access to network system 50A～50D will be via booking service, so encrypt some message to prevent non-user access with a secure computer 53.Basically any encryption system can both use together with the present invention, but would rather be chosen in an encryption system that discloses in the U.S patent No. 4531020 and No. 4531021.
Comprise error detection information in the packets of information and be used to seek system's start byte that packets of information starts.Be included in an information in package and be called as a piece of news.Message is made of one or more order.Multiple order is arranged, distinguish each kind with a unique code number.Order comprises that needed different types of information removes structure and keep TV catalog (catalogue) storehouse, time tag and user's authorization message.
System 50A～50D is the data network of the data that provide by the special format change for all-american user 52.These data are used to set up one " screen program guide " so that make system user can reciprocally see television program listing on their video screen, and the database of being set up by the computer program of an operation on UNIX computer 54 for the information of this network provides.For setting up this database, need data that source (DP) 56 is provided and use the computer that is called as the program listing file that shows inventory file so that supply with.
The TV programme catalog (catalogue) is generated in 56 by seller company, and offers Star Sight company computer center 54 with a kind of simple exchanging form.Which passage when specific which type of TV programme of the information that is encoded reach at.The all passages in the whole nation receive and handled these data 10 days.In case any change of TV list in a needed substrate effectively then they just be transmitted.The specific information and the file that comprise have hereof below been described.
Show that inventory file is sent in the file system in the computer 54 in the electronics mode via the router of an Ethernet that is connected to DP and digital leased line that uses standard TCP/IP program, FTP or other agreed switching consensus standard.File may require compression because the most of data that are transmitted be to use with computer 54 in the agreed data compression algorithm of unix filesystem compatibility.The speed of service of leased line 58 will transmit all data files fully with a rational time span.
File is finished this document with 0800 hour PST and is transmitted to be sent to 7 day every day an of week computer 54.The file of every day transmits the consistent family's catalogue book of login name that will enter into and be used for carrying out the file transmission.
" master " file that downloads to computer 54 will always be used for following 12 days file.Thereby if be No. 10 today, then the data download of today will be to be used for starting time of beginning at 0000 hour GMT of No. 22.
Because data file is to send every day, thus some mechanism must be in place so that allow the renewal of a program inventory having transmitted.This finishes by " renewal " file.A transaction file comprises all change records that produced by a last transaction file that is occurred, and this document is revised data arbitrarily to any unspent date." effectively " date is defined as since the date on the same day and crosses over subsequently date of 11 days.(that is, and all from the same day to by the topped date of " master " file of today, but do not comprise last day).
Last minute list change need " be upgraded " fast, and it provides " upgrading fast " file in 5 minutes after any change item.This file moved to computer 54 at leisure from leased line 58 in one day.
Handle the TV catalog (catalogue)s and be inserted in the master data base with computer 54.During this is handled, eliminate unnecessary information.For example, in 10 days list information, the demonstration of " I like Lanxi County " surpasses 1 time, then only deposits in master data base 1 time for the character string of the title of this demonstration.For each passage and every day, by the information that deposited in for specific which type of demonstration in complete a day and when show.Each demonstration can comprise that one shows inventory and a demonstration description, but not necessarily.
The purpose of master data base is to deposit all TV catalog (catalogue)s in the relevant database of the method access data of a use standard.Data are recovered the effective method marshalling with a kind of data that make.
The TV viewer receives a cover television video frequency signal in viewing location.Cable TV provides the source to distribute broadcasting and satellite programming passage to special modality.Each cable companies all has the channel allocation of a uniqueness.Each geographical position all has one to be enclosed within the broadcast channel that its position can receive, and in order to supply with and this subscriber-related TV catalog (catalogue) to the user, a subscriber unit must have a program channel table and channel allocation.
The channel allocation of every suit uniqueness is assigned to a reception group (ReceptionGroup).What receive set associative system with each is postcode, the inventory of program receiving passage and the channel allocation that is used for these passages that an area-name, reception group kind (cable, broadcasting, satellite), a group can received program passages.
Check and examine inquiry reception group and program channel information as an accent.Transfer (Line Up) information of survey from any source.For example the commercial company of acquisition of information, user, cable companies and broadcast channel are propagated the analysis of coverage area etc.
The accent measurement information that obtains from the single source modification that is not considered.Various processing are used for from multiple source adjustment data to obtain the database of a better quality.When a modification is verified, produce one and be altered to master data base.Relatively all remaining accent are surveyed data and are produced a master data base.Getting in touch a kind of topmost problem of transferring survey and other accent to survey is to examine each to transfer the postcode of surveying identical.In case examined zip code information, then can and examine channel allocation by the comparison of the user in call cable companies or the zone.
In case TV catalog (catalogue) and reception group data are logged in the master data base, then these data of computer programs process are suitable in PBS data network data flow transmitted to provide one.For tiny node (Station Nodes) and user's 52 these data compressions and combine best.The specific format of output stream is described in the back.
With data type grouping and arrangement output stream.Owing to use this method in the subscriber unit, preferably with special rank order data.This permission subscriber unit is collected a complete TV list in the batch data.Data block and their order are as follows: 1, privacy key;
The need to be keep secret key is so that those data of receiving of privileged user only of restriction access.The part of data flow uses the data encryption standard privacy key algorithm of manufacturer's standard encrypted.These keys can change at any time.For the user who keeps all applications is speciallyyed permit and is gone to change key, the message of the privacy key that comprises current and future of a serial of transmission.Send the first cover decruption key of a subscriber unit in the network information, the special permission unit goes to begin to collect data.Key in this authorization message is with a secret key encryption, and this key is unique for each subscriber unit.2, subject data
Most of TV programs constitute with type of theme and subtype.Master data base comprises one group of attribute for each type, is used to refer to the TV program and whether belongs to a special type.The independent set of each of type attribute is specified by an independent subject identification.A subject identification based on a set type attribute is specified each demonstration.Transmit a table textual description is assigned to each subject identification in the subject data piece.3, the change that saves time in the daytime
The data of a fixed time of transmission when saving time beginning and end in the daytime.On data network, transmit 1 message repeatedly, the correct time in when beginning of saving time between the appointed date and the correct time when saving time end in the daytime.Subscriber unit 52 is gathered this message and is adjusted local zone time and go to compensate timesaving influence in the daytime.4, reception group data
Reception group data comprise that organizing needed passage for all independent receptions transfers the survey data.These data comprise area I D (with the unique numeral that receives set associative), regional kind (broadcasting, cable, satellite), passage ID (the unique numeral that links with special modality) and tuning port number (must adjust TV so that the passage of reception).During special permission was handled, special subscriber unit 52 was assigned in the reception group arbitrarily.Subscriber unit is only handled the data in the reception group of being speciallyyed permit.All other reception group data are ignored by subscriber unit.5, channel data
Each path marking in any reception group must have a channel data order that interrelates.The channel data order comprises the information of relevant that passage; This machine port number is (if broadcast channel then is the tuning passage for that passage, the call letters of standing, network members (ABC, NBC, CBS) and for the abbreviation of tunnel name.Last abbreviation is used for the passage on the subscriber unit is shown 1 to 4 character icon.Each cycle data is for any special modality transmission primaries only.6, show listings data
One shows that inventory comprises that a TV program and these programs are for a special modality and the inventory of the duration on date.Order comprises a passage ID, for starting time of top line and subsequent program and the inventory of their duration.Each demonstration comprises that one shows that ID and one optionally describe ID, shows ID and describe ID to be and their demonstration title or a unique numeral interrelating respectively of the text of description.Each demonstration comprises that also one is pointed out whether it is to watch the sign that will charge at every turn.7, show title data
Each unique demonstration title sign has a relevant demonstration title command.Show that title command comprises demonstration ID, theme ID and shows title text.Only comprise once the demonstration title that each is unique in the data flow, and can be used for more than 52 time by subscriber unit.Show that the text in the title compresses with the Huffman compress technique.8, show data of description
Each shows that the unique demonstration description reference in the title has (demonstration description an order that bar is relevant.Show to describe to order and comprise demonstration) describe ID, MPAA grade, evaluation (Crit-ics) message level and show and describe text.Each unique demonstration is described only once involved in data flow, and can be used repeatedly by subscriber unit 52.Show that the text in describing compresses with the Huffman compress technique.9, tiny node data-message
Each PBS tiny node receives those will be by the tiny node data block transmitted.Have only the needed data of those subscriber units in the tiny node receiving area just to be sent to this tiny node.For example, the tiny node in San Francisco only receives those for the cable system that is received by the user in San Francisco and the data of TV platform.The tiny node in San Francisco does not receive the data in Los Angeles.
The purpose that is used for the security software of system of Star sight company provides the CA that star vision (StarSight) company data is flowed.Partial data is encrypted." the access catalog (catalogue) is with good conditionsi " means a subscriber unit 52 must know decruption key.Have only those unit of having been speciallyyed permit can the receiving and deciphering key.
Conditional access system comprises 3 levels of encryption.Highest level, each user has a RSA public/private key right.Next level; 256 above crowd (batches) in unit share a DES key, are called as batch key.Minimum level, the DES secret key encryption of sharing with a unit program guide all speciallyyed permit be called as program key.The program key of periodically-varied distributes under batch key, and batch key distributes under RSA key, and it is other to provide one 3 level.
Various keys or distribute in factory, perhaps distribute in next-door neighbour's last message as following:
The serial numbering of a RSA private key and a recognition unit is programmed in factory.Star vision (StarSight) system maintains corresponding RSA public keys.
Criticize key and be dispensed in the authorization message, encrypt to it by user's RSA public keys.Authorization message also give element number, " type service " file in one of unit batch numbering and batch and be current and the key of next program, authorization message normally Star Sight system and should the subscriber unit in zone between mutual for the first time, reallocate to criticizing although it can at any time be sent out.Program key is with an encryption key distribution distribution of messages, with one batch of secret key encryption.According to a unit in criticizing, encryption key distribution message points out also whether a subscriber unit is still speciallyyed permit.
2 secrecy system functions are used for handling special permission and encryption key distribution message.The 3rd function is used for deciphering the text of having encrypted with one of program key.Text is encrypted with CBC (CBC) pattern.
Program key periodic variation and use the encryption key distribution distribution of messages.If the user is not speciallyyed permit, then they will can not receive a new encryption key distribution message, thereby can not decipher the TV catalog (catalogue).
Microprocessor will be carried out a lot of tasks as described later.Each task is service in real time, but need not finish in each time period.One " circulation " carried out and is used to fulfil this function.A main ring calls each independent task successively.When task is called,, go to finish the function of its defined according to its current state.Need these tasks so that in the cycle, finish whole tasks or part task at a preset time.Like this, all tasks all have an opportunity to carry out their assignment of missions in a time cycle.After last task is finished its function, each task will be carried out once more.2, storage management
Television programme data is to change dynamically and always.Show inventory, show that title and description are all to change length variable and every day.Thereby, disposing a storage management system, this system allows the recovery of dynamic assignment and data block.Memory is divided into the allocation block of identical size.The storage stack piece is called a storage pool.Produce a processing list so that quote memory block in the pond, an application software subprogram is come allocate memory with reference to the one or more allocation units in the storage pool by generate and store a project in processing list.By discharging the memory benchmark in the processing list, memory can be removed distribution.
Demand in the application requires to have the adjacent block above the memory of single memory length in the pond.When needed, by distributing a plurality of adjacent memory blocks to finish.
After many memory blocks were removed distribution, storage pool will be by division in flakes.Many memory blocks that change size are arranged, and they are adjacency not.One of background task is to eliminate the division storage pool.Move a process memory block that is assigned with is moved to the minimum memory location that may exist.When a memory block was moved, the benchmark for those memories in the processing list was changed.Like this, application program will have a benchmark for memory block.Each allocation units is moved, thereby the piece of any removal distribution between the piece that is assigned with is disintegrated.Its last result be all memories that are removed distribution be in the highest memory location that may exist and also all piece adjacent.3, VBI data processing
The VBI data are decoded from video flowing and are used 8032 microprocessor processes.A buffer is used to store data and sink information bag.A comparator is used to detect an ad hoc synchronization character sequence.These characters one are detected, and buffer is reset and the packets of information origin or beginning is collected.If detect the correct cyclic redundancy check (CRC) of packets of information origin or beginning, then the remaining part of packets of information also is collected.After having collected complete packets of information, calculate a real whole packets of information of additional CRC stoning and inerrably received.In case be verified, then packets of information is broken and each internet message is sent in the command processor.4, command processor
Command processor determines whether to be provided with encrypted bits in the origin or beginning of order, if be provided with, then data will be passed through security components.Thereby security components is returned to command processor with data decryption and with it.Command processor plays a sender's effect.Function according to order sends to order in the suitable processor module.5, database processing
Data base processor has a responsibility for storing and recovering all TV list and channel datas.It deposits in the database from command processor reception data and those data.Use a cover funcall application programs restore data.The structure aftermentioned of database.6, secrecy processing
Security processor has 2 major functions: key management and data decryption.When having received the message that comprises correct sequence numbering or batch numbering from command processor, security processor receives message and decrypt.Under the situation of an authorization message, with RSA private key data decryption.In order to use decoding and storage batch numbering, batch key and other control information in the future.Under the situation of key management messages, use batch key decoding data and be use in future stored information.Under batch key, encrypt the program key that is assigned with.7, user interface
The user interface basic input of remote control command as it.A user is by pushing the various functions of Long-distance Control button request.User interface receives and responds these orders with requested display screen.In addition, when a recording start or subscriber unit are attempted to collect data, synchronously produce display command.
The application's book has above 20 kinds difference and not identical display screen drawing is arranged.Every kind of display screen has the special state corresponding with it.The form of data and screen depend on the front screen, time on the same day, database content and pushed which Long-distance Control button.A state table is used to define screen flow.
For the screen of each definition, an inlet function, outlet function, update functions and a key handling function display are arranged.Call entry function when having imported a state is for the first time gone to collect all data that need and is removed to format screen.Call the outlet function, remove to discharge memory and for the data of screen.If show to finish arbitrarily or recording start or finish all that per minute calls the change function once arbitrarily, go to change the screen time and open screen once more.In case under a special state, table has comprised the benchmark for other software function of each key of Long-distance Control aspect.These functions are performed when pressing the respective remote control button.
User interface is also managed the array of an ejection (pop-up) window, and they can synchronously manifest or disappear on the screen, perhaps pushes by key to manifest or the response that disappears.Ejection type more than 18 kinds is arranged, defined the screen priority for each, promptly in a single day a plurality of ejections are on screen the time, and they one topped one.These ejections can be cursors, show description, error message, help information or for the request of more information.Each ejects type its inlet, outlet, renewal and key one handling procedure, as the main screen state.
In addition, user interface can carry out alternately, keep selecting and the order of program passage, control tuner from the guide screen, carry out subject search and control one " spirit " (demon) during one is automatically collected catalog (catalogue) or the like in from the scheduled time of data set provider passage, the response locking or the database of unblanking database user and program guide.8, VCR record
The purpose of record management server is the inventory of reservation record request and in reasonable time, suitable passage activated.User interface defines three kinds of records, singles, reaches once a day weekly.The user can note demonstration that he or she is watching prevailingly or select a special title from one of guide screen.The user can move to cursor on the special title on one of guide (grid, passage or theme), pushes " record " button, and to select program be the record single, still weekly or once a day.
In case the user has confirmed record request, then in records series, produce an inlet (en-try).Records series comprises for each inlet in these kinds record.Under the situation of record every day, in the logging sequence, produce the nearly inlet more than 5.For record and single write down single inlet of generation weekly.The logging sequence description so whole record, these records will carry out next week on the horizon, and by showing the zero-time classification.
From executed in real time, call a record " spirit " to determine if it is the time of activated.Check that the guiding in the logging sequence enters the mouth to determine if it is the time of activated.If then carry out a software function and go activated.In case record is started, then record " spirit " goes to determine whether it is the time of end record.When searching dwell time, carry out a software function and go end record.
Starting and finish VCR record and carry out with several different methods.These methods under the situation of not using a cable converter, are used the following actions activated based on the configuration of subscriber equipment: 1, connect the VCR power supply.2, VCR be tuned to the passage of wishing.3, VCR is placed logging mode.If used cable converter, then carry out following actions: 1, energized.2, VCR be tuned to passage 2,3 or 4.3, cable converter be tuned to the passage of wishing.4, VCR is placed logging mode.5, telling user interface software current is which by tuning passage.
Be end record, VCR is changed to stop mode and energized.In all cases, these orders are finished by the infrared ray order is sent to this equipment.
Another function that writes down " spirit " is to check queuing weekly and record requirement once a day, and produces a new inlet in queue work.For example,, in queue work, just produced 5 inlets if imported the request of writing down every day in the morning on Monday for the program in an afternoon, that is, and Monday, Tuesday, Wednesday, Thursday and Friday.After the record of the afternoon of Monday is finished, then delete the inlet that is used for Monday in the queue work.Record is smart to be found out a time and joins in the queue work with the inspection record queuing and for next week one.This inlet will join in the queue work ordinal position with chronological classification.
In addition, when being intersected on the border that saves time in the daytime, spirit will keep the normal starting time.That is, spirit must be in autumn the starting time that was added to a demonstration in 1 hour, and must deduct 1 hour in spring, and saving time in the daytime of being provided can be applied in user's the zone.
The deletion of original record kind is handled singlely or numerously depended on to record management server.
9, screen display (OSD)
A screen display is used for showing text and the graphical information of forming various display screens.A common interface is used to control various device, has 3 kinds of equipment to use: ITT TPU2740, ITT CCD3005 and Zilog Z89300.User interface has a cover to be defined as rectangle, a passage icon of drafting of rendering text, an embossing of drafting and the function of display properties is set.One cover software function is used for these orders are translated into the appropriate function that is used for particular device.
The details of subscriber unit 52 is provided among Fig. 5.Following description serves as according to carrying out for television reception special use (TVRO) system (see figure 4) with subscriber unit 52.Through suitable modification, subscriber unit 52 can be incorporated a cable decoder case into so that use jointly with cable system.Subscriber unit can also pack into television set or VCR
sOr provide with the separate unit of a separation.
This is the description to the electronic hardware of Star Sight TV broadcast " TVRO subscriber unit " 52.TVRO user is the people that have the family expenses satellite parabolic antenna of seeing that TV is used.TVRO is the meaning of " TV receives special-purpose ".TVRO subscriber unit 52 will be linked up with user TVRO satellite system.And will make the user can subscribe the electronic program guides service of star vision (StarSight) company.TVRO subscriber unit 52 is self-contained, as to separate unit, can install serially with existing user TVRO equipment.

The core of TVRO subscriber unit 52 is " 8032,8-bit microprocessor " 100.All parts of this microprocessor control subscriber unit.A concise and to the point description as a reference of this processor is provided.As will understanding more details, can from 8032 databooks that Intel or Signeties provide, find.
8032 have one 8 bit data bus and one 16 bit address bus.The most-significant byte address wire is the current address always, and the least-significant byte of address wire and data/address bus time division multiplexing and external address latch of needs are so that go this bus of demultiplexing.This latch is positioned at DBE1200 gate array 103.8032 have 2 address spaces." CODE " space and " DATA " space.The DATA space will be further divided into RAM memory block and I/O district.
" CODE " relates to the arbitrary access to program ROM.Program CODE space is that 64K byte long and 8032 only can be from this space " READ (reading) "." PSEN " (can stored program) line is used in all code accesses.-WR and-the RD line do not keep during the CODE access.+ AE is the signal that is used for the demultiplexing address bus.The trailing edge of+ALE is with the least-significant byte of latch address.And-PSEN will be kept to be started ROM and reads.Current design has the EPROM-CS line of ground connection all the time.This has produced EPROM " OEACCESS " time of reading definition rule for ROM.By the standard of today, this microprocessor bus is regularly very short, and allows to use cheap ROM.
" DATA " relates to the arbitrary access to outside RAM102.Extra additional hardware is added to TVRO subscriber unit thereby DATA zone and can expands above the 64K addressing and limit.This is to finish and also will discuss in the back via segmentation " base register " 104.The 8032-RD gating will support the RAM data to read, and-the WR gating will support the RAM data to write.SEN will not support in the data access period P.The RAM data access can only be carried out along " MOVX " instruction.Do not have other 8032 instructions to make-RD or-WR goes to keep.Explanation once more ,+ALE is used for latch address ,-RD or-WR will keep and start data transaction.Read data must be just-before RD is invalid effectively.Write data-All Time that WR keeps is effective.
Also have one " 64KI/O space " together with the RAM data space.This input/output space occupies identical initial 64K section as DATA RAM ground.Have one to be called+signal of DRAM-ENABLE is used to define will be by the zone of access.
Input/output space is provided with system control register, has 18 to write register and 13 read registers.These registers are used for controlling the various subsystems of subscriber unit.As characteristics such as clock frequency selection, serial bus control, I.R, state and controls all is by this registers group control.The control register that in peripheral chip, also has other.2 universal serial bus of 8032 uses are communicated by letter with these peripheral chips and are controlled." IM BUS " 108 is that 3 wire serial bus are used for and transaction unit (TPU 2740) 124 contact, and TPU 2740 collects the VBI data of input and format and shows the topped screen of various Star Sight.
Software universal serial bus 110 is used for getting in touch but also contact IRBlaster chip 116 with security processor.This is the 2 line buses that a unique series timing agreement is arranged.
The preceding 64K of 8032 address spaces has the overlapping function of 3 separation.
1. if keep-PSEN, then CODE ROM will be by access.
If 2.+and the DRAM_ENABLE=logical zero, then the I/O register will be by access.
If 3+DRAM_ENABLE=logical one, then the preceding 64K of RAM will be by access.
Above-mentioned 64K zone always RAM and length overall is the 512K byte.8032 signal summaries

8032 data address spaces are the 64K byte long only.TVRO user need store the program data greater than the 64K byte." read and write base memory " allows 8032 accesses to surpass the annex memory of 64K restriction.
8032 use one is called as " data pointer register " inside 16 bit registers (DPTR) in order to preserve the address of outside DAT position.Base register (being positioned at the DBE1200 gate array) keeps appending on the data pointer value in order to constitute the 16 other place values of actual address ram.With respect to data pointer, the plot memory content moves to left 4, thereby, address ram become 20 long.20 long total data RAM sizes for a 1M allow.8032 can be accessed in any 64K block of bytes of the external RAM of starting under the address that writes in the base register.(because base register moves to left 4, so 8032 can be accessed in any 64 byte section of starting on uniform 16 byte boundaries).2 base registers are arranged, thereby can finish memory block quickly and move.If the value of DP-TR during piece moves to reading each time all to change and before writing, changing once more, then will be very slowly and be pretty troublesome for software.Double-basis location register allows you that the initial address of reading (source) piece is put into and reads base register, the initial address of writing (target) piece is put into write base register.So just can after reading, go to write identical DPTR address and constitute a software ring.This DPTR is added 1 and repeat this process then.This allows software to remove soon the piece of mobile data Anywhere among the RAM externally.
Also added a kind of regulation so that make base register invalid apace.Signal+EN-ABLE-BASE will make the output of two base registers be all 0.This does not change the content of base register.These characteristics provide the fast method of the initial 64K block of bytes of access RAM.The read and write of RAM all will be at same position.Will there be (register image, software counter value, system parameters etc.) in the initial 64K piece in the data that processor is relevant.High-order piece is used to store the TV programme information.
Table II illustrates DPTR and how to be added to base register to get on to constitute 20 address rams.

+ DRAM_EN is necessary=0 go to access I/O zone.Data RAM is described
As above-mentioned, data RAM 102 storage TV performance guide informations.This RAM can be 3 kinds of sizes, 128K byte, 256K byte or 512K byte usually.The TVRO product uses the 512K byte.Data RAM is used " PSRAM " chip, and the pseudo-static PSRAM of " PS " representative is a standard DRAM, is used the output pin of static RAM (SRAM) packaged.Add that other logic is to simplify refreshing of DRAM.These PSRAM
sAlso have the resident characteristics of energy-conservation data, when voltage drops to 3V, work.
4 kinds of patterns of PSRAM operation are arranged in this product, and they are:
1, ascending order pattern.
2, normal data transfer mode.
3, descending pattern.
4, energy-conservation data residing mode.
Can use 2 kinds of sizes of PSRAM among the design.128K * 8 or 256 * 8 chips.There are 2 128K of a usefulness * 8 parts to go to constitute the regulation of global memory 256K byte.
These 2 parts have different slightly pin output and different slightly method of works.The affix circuit goes to compensate these difference.Must with depend on 1 of software setting using which kind of chip be called as+512KRAM the position.
Also has PSRAM
sMust and be about to pass through " descending " state before the outage after the energized by " ascending order " state.The PSRAM operation, the ascending order operation
The beginning of switching on just, PSRAM
sMust any read or write can carry out before for " ascending order ", for 128K and 512K, the ascending order process has JND.Additional this process is so that guarantee at PSRAM
sKeep logic and the particularity regularly of PSRAM during for energy-conservation data residing mode.When system power supply is lost, there is a regulation to go to use a big capacitor or a battery to keep PSRAM
sEnergising.When outage, in order to preserve the PSRAM data, the input of some PSRAM must be maintained at a known logic state, and on the pin, when they had been transfused to a known logic state, these pins must be deferred to the timing constant that is defined.These pins are different for 128K with the 256K parts with logic level.
For 128K parts :+Chip-Enable2 (pin 30) and-upgrade (pin one) to be transferred at power supply and all must to maintain logical zero when guaranteeing that data are resident.When the data residing mode moves on to operate in standard mode ,-upgrade (pin one) must be at least in+225ns rising before CHIP-ENABLE (pin 30) raises.
For the 512K parts: be transferred to when guaranteeing that data are resident at power supply ,-chip-Enable (pin two 2) must maintain logical one and-OE/-renewal (pin two 4) must maintain logical zero.When the data residing mode moves on to standard operation ,-Chip-Enable (pin two 2) 50ns that must before-OE/-renewal (pin two 4) raises, raise at least.
Also has a timing restriction that after PSRAM REFRESH, how long can produce said sequence.The above-mentioned timing of ascending order logic control in the DBE1200 gate array.After a power-on reset (Poner On Reset POR) order is finished, microprocessor triggers one and is called as+position of ascending order [Wr Addr7400 Hex, 5].(necessarily always this position being turned back to logical zero), be triggered+the ascending order state machine will be started in the ascending order position.This state machine will be waited for the end of next standard refresh pulse and will use above mentioned appropriate timing to go to shift compulsory logic level.Approximately per 11 μ S send refresh pulse and ascending order and handle and need about 1 μ S, from time of settings+ascending order to attempting the PSRAM access first time, software is waited for 15 μ S at least.PSRAM operates (standard operation)
Standard P SRAM operation is very direct, and refreshing is automatically, and is transparent to microprocessor.The per at least 15 μ S of PSRAM refresh once.Refresh address produces in PSRAM and is transparent for the user.In order to realize once refreshing, refreshing pin and must in a short time, remain low level on the PSRAM.In order to reduce circuit design, refresh requests is produced divided by 256 backs by internal clocking.Under the situation of 24MHZ clock, approximately per 10.7 μ S take place once.
The refresh pulse that gives the PSRAM chip can not take place in PSRAM reads or writes identical time of access.Because refresh requests is asynchronous with any PSRAM access, so-the PSEN line is used to start and refreshes.When having deleted refresh requests, refresh circuit will be waited until the trailing edge of the next one-PSEN.When a CODE access ROM began ,-PSEN descended.8032 read the institute of OP-CODES free in CODE access ROM.In this time, 8032 can not access PSRAM.Refresh very soon, and before-PSEN CODE reads and finishes, just finish.
Attention: this system must have-and PSEN triggers so that refresh PSRAM.In standard operation, this will take place in All Time.If you have used one 8032 simulator, then to be noted.If your interrupting or stopping simulator then refreshes also and will stop.Even when a simulator produced breakpoint, most of simulators still had a kind of selection and go assurance-PSEN to continue to keep.PSRAM operates (descending operation)
Descending is opposite with ascending order, and system has one " early alert loss of power detector ", and it will interrupt 8032 before the voltage of supplying with begins to descend.By preserving any critical PSRAM data, 8032 respond these interruptions, and, keep the descending position.Descending will force PSRAM critical be input to their appropriate states, and will guarantee to keep regularly specification.The terminal that the descending logic refreshes up to the next one is just started the suitable timing of assurance.The descending rule is so that as follows.For the 128K parts:
+ Chip-Enable2 (pin 30) must-upgrade (pin one) be forced logical zero before at least 60ns reach logical zero.After power supply stops, because gate array output is uncertain, so peripheral components will be kept these lines under logical zero.For the 512K parts:
-Chip-Enable (pin two 2) must-OE/-upgrade (pin two 4) be forced logical zero before at least 50ns be forced logical one.PSRAM operates (energy-conservation data are resident)
Critical input pin keeps the voltage of permanent (seeing above-mentioned) and PSRAM to remain on 3V when above under their energy-conservation level, and data will keep.PSRAM is energy-conservation to latch
With one to PSRAM
sThe same spare capacitor of power supply is to the J-K flip flop power supply of very little electric current.This trigger makes software know whether voltage drops to during power remove to be lower than the minimum voltage specification.
When beginning to switch on, this latchs and will charge to logical zero.Microprocessor can be read the state that this latchs on+RAMV-OK line.If latch is 0, then will be considered to voltage and be reduced to and be lower than the resident specification of PSRAM minimum data and all RAM data are invalid.If it is latch=" 1 ", then still effective from energy-conservation preceding beginning PSRAM data.
If+RAMV-OK is a logical zero, then microprocessor can be provided with it and is logical one after himself testing and diagnosing.Be set to logical one in case this latchs, then it will remain to PSRAMVdd and be reduced to and be lower than till about 3.1V.This is set latchs 5 conditions that need
1, PSRAM voltage must be greater than 3.1V (this will discharge the trigger reset pin).
2, the PCB+5V power supply must be greater than about 4.5V (this delivery system POR).
3 ,-the ENBLAT line must be set to logical zero.
4 ,+the BANDO line must be set to logical one.
5 ,+the LAT-CLK line must trigger to logical zero triggers then and be logical one.
-ENBLAT and+the LAT-CLK line drives by 8032 microprocessor PORT pins.These pins will be logical one by 8032 hardware initialization in the POR time.+ BANDO line is reset to logical one from the DBE1200 gate array and in the POR time.
By requiring all these conditions, being hopeful to latch when charging can not be by pseudo noise misoperation set.Read a logical one if latch, then a good idea is a verification and unit to be arranged to go verification msg effectively (just under the situation that latchs the enough noise misoperation set of energy) in PSRAM.
Selecting MC14XXX series cmos device for latch cicuit is because this system has been proved to be and also has only low-down current drain under worst case.DBE1200 gate array 103

Table IV 8032I/O read register PSRAM control
The control logic of PSRAM is shown in the 2nd page of appendix A.These logics comprise some simple doors.These goalkeeper's control signals are routed to the suitable pin of the pattern that depends on this chip place.Chip has 2 kinds of memory-size patterns, 128K and 512K.This also is an ascending order pattern and a descending pattern.PSRAM control signal XRFSH_18 (ReFreSH or address position 18)
This is a dual purpose signal of linking on the PSRAM chip pin 1.During ascending order, this signal is the pattern of being correlated with.
In the 128K pattern ,-upgrade being sent to this pin.
In the 512K pattern, 18 be sent to this pin from the position of address MOX.During descending, this signal is forced logical zero.XRAM_OEO (RAM output allows 0)
This is a dual purpose signal of linking on the next stage PSRAM chip pin 24.During ascending order, this signal is the pattern of being correlated with.
In the 128K pattern, this is to read output for the PSRAM that hangs down one-level 128K PSRAM chip to allow line.Only can be in the address for keep (activity is low) to the 128K of next stage and during 8032 RD keep.
In the 512K pattern, this is that PSRAM reads output permission and refresh input signal.If this signal is kept voluntarily, then take place once to refresh.And if-Chip Select pin keeps together, then carries out PSRAM and read.During descending, this signal is forced logical zero.XRAM_WEO (_ RAM writes and allows 0)
This signal should be linked the pin two 9 of low one-level PSRAM chip.Selecting to carry out a PSRAM when keeping together when the effective chip of this signal and writes.During ascending order, this signal is the permission of writing to the PSRAM in 2 patterns.This signal is not noted XRAM_OE1 (RAM output allows 1) during descending.
This is the dual purpose signal that should link upper level PSRAM chip pin 24.During ascending order, this signal is to allow (Output Enable) control for the output that the upper level PSRAM from the 128K pattern reads.This signal is not used in the 512K pattern, because the one-level chip is not installed in the there.During descending, this signal is not noted.XRAM_WE1 (_ RAM Write Enable1) (RAM writes and allows 1)
This signal should be linked high one-level PSRAM chip pin 29.Selecting to carry out a PSRAM when keeping together when the effective chip of this signal and writes.During ascending order, this signal is a signal of the upper level PSRAM in the 128K pattern being write permission.(note, in current design, do not use " upper level " chip in the 512K pattern).During descending, this signal is not noted.XCE1 (chip allows 1)
This signal is the dual purpose signal that should link PSRAM chip pin 22.During ascending order, this signal allows the reading and writing in 2 kinds of patterns of PSRAM chip.During descending, this signal is forced logical one.During energy-conservation data residing mode, 512K PSRAM chip requires this line to be forced logical one.At 128K PSRAM
sThis line is invalid.CE2_A17 (+Chip Enable2 or Address_ position _ 17) (chip permission 2 or address bit _ 17)
This is the dual purpose signal that should link PSRAM chip pin 30.During ascending order, this signal is an associative mode.
In the 128K pattern, this signal is connected to+and chip allows (+Chip Enable) and always is logical one.
In the 512K pattern, 17 be routed to this pin from the position of address Mux (Address Mux).XWRSTROB (_ Write STROBe) (write gate)
Writing the phase, this be 8032 write gates than short run this.XW_RSTROB is the timing signal that is used to write PSRAM.Rising edge data at XWRSTROB are written into PSRAM.This rising edge reached before the 8032_WR rising edge to guarantee to satisfy any PSRAM data hold time.Base register and address multiplexer
Gate array illustrates base register and PSRAM address multiplexer for graphic the 3rd page and the 4th page in the appendix A.See above-mentioned description for the base register function.This part describes with circuit.
Base register illustrates the 2nd page of left side, and the output of these registers is passed through AND gate before entering adder (Adders).Allow the output of base register promptly to be forced complete 0 with door at the input of adder.
The output of adder turns back to MUX.The result that this MUX reads adder (READ ADDERS) in the most of the time by default handle is placed on the PSRAM address pins.Have no idea to know that 8032 will go to write, unless have _ support of WR gating.When _ when WR kept, a trigger was converted to WRITE ADDER output with MUX.Select to read adder for default value, longer slightly because RAM reads than writing.Because dual adder is arranged, therefore write address is exactly stable as long as the WR gating is kept then.I.R. receiving circuit
I.R. receiving circuit has multiple modes of operation, and these operational modes depend on remote button and unclamp or pushing always.This circuit is at the 5th page of appendix A.
When a valid code is recorded to I.R. receive data register (0800R) and goes up ,+IRR_VAL (IR Receive Valid IR receives effectively) position and+VALTILRD (the effective TILRD of Valid TILRD) position is set.+ IRR_VAL position will keep set till remote button is unclamped.2 kinds of method removing+VALTILRD positions are arranged.
1, reading the I.R. receive data register will remove+VALTILRD.
If 2 unclamp remote button and push once more, then+VALTILRD will remove when button is pushed once more.
+ IRR_NC (I.R.RECEIVER NO CHANGE I.R. receives no change) reads set the zero-time of I.R. receive data register.And will keep set till remote button is unclamped.
-push remote button+IRR_RDY just to raise and keep this set released up to button.Secret clock generator
Secret clock generator is shown in the appendix A the 9th page following middle part.This is a programmable clock generator for the secret chip of Motorala.The initial sample (Spec) of this clock is 5MHz.In order to allow to change the oscillator frequency, this clock is made programmable.
The high time of this clock cycle and low time can both the programmings independently by writing I/O address 3C00Hex.The high time is hanged down the time with hanging down the nib setting with high nib setting, this time is the product of input oscillator frequency.
This circuit is to work by 74F19 type counter that the program nibble is packed into.These counters are set to " down counter " and successively decrease any one time in only with them.Behind a counter to 0, output is triggered, the counter heavy duty, and other counter will successively decrease.Inverter at the program register output is provided with initial value so that " divided by 7 ".I.M. universal serial bus circuit
I.M. bus is used for and the TPU2740 chip communication.I.M. bus circuit is shown among the figure.As detailed description, discuss the characteristic of I.M. bus to this bus.Say that simply the I.M. bus is 3 line serial communication bus.These 3 lines are called as I.M._CLOCK, I.M._DATA and I.M._ sign, the DBE1200 gate array is the main frame of I.M. bus always, thereby driving the I.M._CLOCK line, the I.M._DATA line is a bidirectional data line (with an outside pull down resistor open drain (Open drain)).The I.M._IDENTIFX line is the output that is used for identification " I.M. address ", and goes to finish transmission.One " IM BUSWRITE (the IM bus is write) " is the transmission of 8032 output being passed to the IM slave.One " IM BUS READ " is the transmission from IM slave to 832.
I.M. bus transmits and always begins with 11 byte address, then is the data of 1 or 2 bytes.How many data bytes a position that is called I1BYTE (3000W.O) defines is gone to transmit.Remaining position that is called as WXR_BIT (3000W.1) determine to be transmitted and to be read or write.The 11st page of appendix A illustrates I.M. counter and control logic, and the 12nd page does not go out I.M. data shift register.I.M. circuit general introduction
I.M. circuit is by control and data register operation.Be summary below.
I.M. bus address register (12 pages of XL_IM_AD of 2000W).8032 will write and 8 bit address of setting up the auxiliary device of communicating by letter here.Be sent to shift register among these address latches 74HCT273 in the drawings and when transmitting beginning.If in continuous 2 times are transmitted, distributed identical address, then need not this register of heavy duty.The byte that is written to this register will always transmit first byte that writes from gate array for all I.M..
I.M. write data 2 registers (the 12nd page of 2400W., XL_IM_D1).The byte that is included in this register will be the 2nd byte that is removed to during I.M. writes on the bus.This register must heavy duty after each the transmission.
I.M. the byte that is included in this register of write data 2 registers (the 12nd page of XL_IM_D2 of 2800W) will be the 3rd byte that is moved out of during I.M. writes, but only be set under the situation of 2 bytes transmitting length.This register must heavy duty after each the transmission.
I.M. read data byte 1 (the 12nd page of XRD_BYT1 of 1000R).After reading transmission, this register will comprise the Input Data word joint.If 1 byte is read to transmit, then data will be in this register.If 2 bytes are read to transmit, then received the 2nd byte will be in this register.
I.M. read data byte 2 (the 12nd page of XRD_BYT2 of 1400R), after 2 bytes are read to transmit, this register will comprise the data byte of first input.During one 1 byte is read to transmit.OPADD will turn back in this register and finish.This returns characteristic and can be used in error detection or diagnosis.
I.M. position 1 definite transmission of this register of bus control register (the 9th page of XIM_CTRL of 3000W) is read or is write.The position 0 of this register determines that 1 or 2 data bytes are transmitted.
I.M. the initial transfer register of bus (the 11st page of XS TRT IM of 2C00W) writes this register to any value and will start the I.M. bus hardware.
I.M. bus state register (the 6th page of XSW_LO of 1800 R), the position 7 of this register comprises+the IM_BUSY line.This line is " height " during I.M. transmits.
I.M. circuit operation
The 11st page logic control I.M. bus transmits.I.M. the oscillator clock (OSC_2) of clock (IM.P.CK) and 8032 inputs all obtains from the 24MHz oscillator.Consider the input oscillator, 8032 not specific any timings, and consider the 12MHz input clock, specific timing is very freely.Because this reason, must supposition from 8032 and the starting of IM_PCK to transmit pulse asynchronous.3 triggers of beginning in the left side, figure middle and lower part are used for again synchronous these signals and remove to start I.M. and transmit.
Started transmit after, the 74F269 on the 11st page will start and count since 0.The EN-IMCK line allows the IM_P_CK door to output to I.M. bus clock pin one 4, and preceding 8 clocks will write down this address and will keep at this time I.M. tag line.When register remembered 8, the I.M._ tag line was with invalid.
If during an I.M. writes on and carries out, then the I.M._DATA line will continue an output for the remainder that transmits.If it is underway that I.M. reads, then behind the 8th counting, the I.M._DATA line will be transformed into an input from an output.At the counting 16 of the state that depends on I1BYTE (3C00W.O) position or count 24 backs and transmit with abort.
After all clocks are finished, the I.M._ tag line will be simply pulsation (pulse low one more time) that one more is little be used for showing that this transmission finishes.In this whole time, will keep IM_BUSY position and effective to 8032 as state.Obtain IM_P_CLK by removing the 24MHz oscillator with 32.This produces a clock edge at about each 1.3 μ S.Whole 24 clocks transmit approximately with 32 μ S.Timer on duty (WATCHDOG TIMER)
Timer on duty is on graphic the 13rd page of appendix A gate array.This timer energy enough positions EN_WDOG (3000W.7) moves and stops.This timer on duty resets with the standard operation by writing address 6400W.The data that write this address are invalid.
Timer on duty be 16 long and with the OSC_256 clock regularly, this timer is made by the out-of-sync counter piece (I_SCBR) that the gate array seller provides.Timer on duty is since 0 starting and counting.If it is allowed to overflow, then will keep to 8032 reset line.Power supply to the reset line of gate array also will be kept.8032 reset lines will be kept about 256 clocks before gate array POR internal reset is kept.In order suitably to reset, 8032 at reset line by the clock that needs to fix number during keeping.The interior door array POR circuit on duty that fully resets so it is fixed to reset for suitable 8032, needs to postpone these actions.Attention: the gate array internal POR line chip that resets all sidedly is a known state.Remove outside the IM read data register on OSC distributor clock on the 9th page and the 12nd page.CRC32 multinomial circuit
The CRC-32 circuit is on graphic the 15th～18 page of gate array.This circuit can be used in checks or generates the CRC-32 multinomial.This multinomial is 4 byte longs and to be used to check data complete.
Circuit has 2 operational modes, and CRC-32 is logical and CRC-32 is disconnected.Position X_EN_XOR (6000W.4) deterministic model.When this position is logical zero, the CRC-32 logic is activated and is written to arbitrarily the data of CRC register will use the CRC-32 polynomial multiplication.When this position was " 1 ", the CRC-32 multinomial was invalid, and the data that are displaced in the CRC-32 register do not change.
Circuit comprises 48 place readings according to register, 1 write data register, above-mentioned control bit and control logic.Be the summary of register below.The operation of CRC-32 read register 3 (7000R) CRC-32 read register 2 (7400R) CRC-32 read register 1 (7800R) CRC-32 read register 0 (7COOR) CRC-32 write data register (6800W) X_EN_XOR control bit (6000W.4) CRC32 circuit
Data once enter 1 byte of CRC circuit.Carry out this action by byte being write CRC-32 write data register (6800W).8032 finish write after, hardware state mechanism will obtain byte and it will be displaced in the CRC circuit.(if OSC is 24MHz, and then this displacement is with about 1.5 μ S).After all bytes all move into, can from 4 CRC-32 read registers, read the result.Can turn-off the CRC circuit so that go to 4 initialization of register is a given value.
The CRC-32 write data register is at the 18th page.This be walk abreast into, serial goes out shift register.The end of 8032_WR gating will be started the displacement logic in the 15th page.This logic will be synchronized to the OSC_2 clock to the displacement starting.One 3 digit counter will be counted 8 clocks exactly.Circuit turn-offs then.
The X_EN_XOR potential energy is enough in the CRC-32 circuit is initialized as a known value.Some CRC line map all is set to 0 unstart with 32, and remaining is set to 1 starting with all positions.When X_EN_XOR was set to logical one, CRC-32 circuit XOR _ OR door was invalid.These data that allow to be written to the CRC-32 write data register enter in the unaltered CRC-32 chain of flip-flops.This feature also allows the intermittence in CRC calculates.When take place an intermittence, 4 data in the CRC-32 read register will be read and be stored in to software.At last, these data can be reinstalled these registers once more.The CRC-32 multinomial is:

TPU2740124 plays the effect of opening screen display (OSD) controller and closing caption data (CCD, ClosedCaption Data) VBI data limiter.This device has 2 function independent parts, OSD and CCD VBI data limiter.TPU2740 comprises a RISC based on processor, and this processor is called as fast processor (FP), is used to collect the VBI data, uses serial bus communication, and control OSD.Some internal circuits of TPU2740 communicate between 8032 and 2740 by 3 line IM universal serial bus 108 operation under the 4 frequency multiplication input clocks (have and be 72MHz on the TVRO plate of 18MHz input clock).
TPU2740 is the full digital chip, and base band video data TPU after digitlization can use these data.One 6 A/D converters (MPC660) carry out this digitlization work.
UPC660 is shown in the 1st page of TVRO sketch in the appendix A.The about 1VP-P of incoming video signal and before it can be digitized this signal must be a known DC level by clamp." video clamp and filter " on the 1st page carries out clamp work with " back porch clamp " (Back Porch Clamp) method.This clamp enters the vision signal biasing in the A/D converter, thereby " back porch " zone approximately is 3.69VDC.(" back porch " is the zone that burst signal occupies).

6The low pass filter of forming is at the about 1MHz TPU video that roll-offs.(note: the ratio of clamping voltage is identical with desired vision signal IRE value).
Circuit among the TPU from digitlization video detect vertical and horizontal synchronization.OSD and VBI data limiter use these signals as the timing function.A programmable comparator is used to detection of vertical and horizontal synchronization pulse.It is very important synchronously that appropriate video clamp function goes accurately to detect for this comparator.FP read sync detection circuit output and can the count level line, thereby can read the VBI data from specific VBI line and under correct video scan lines the starting graphic screen show.When comprising that intrinsic is introduced and become the VBI signal of frame data to be detected, the VBI circuit on the TPU will can read FP.FP reads these data and is inserted in the buffer.At last, the VBI data can read through the IM bus by 8032.
TPU needs the horizontal timing benchmark on good digitized video and the stable pin two 7.The horizontal rate signal is from the signal of MC1378+Burst Gate (packet synchronization signal storbing gate) and from pin two 7 feed-in TPU.If these signals are wrong or bad, then TPU can not produce one stable topped.
The OSD part of TPU is made up of superhigh speed buffer storage, character memory, timing function device (timing furctions) and outside 250K4 position DRAM (U9).FP reads the high level graph command and graphical information is deposited in outside DRAM memory from bus.With state that cache, timing circuit and character generator hardware are connected under, TPU, FR outputs to graph data on R, G, B and the FBLOUT line.Use the output of R, G and B can generate 8 kinds of colors.FB LOUT (output of Fast Blanking OUT quickly-blanking) signal determines whether video output will comprise whether the video of R, G, B data or input from TPU will directly pass through.
TPU has a 256K * 4DRAM (U9) and is used to store topped screen and data.This is a fast page mode DRAM and by reading the discarded flush logic of shadow data consistently, in addition no on screen also be like this when topped.R, G, B color conversion device
Star Sight television broadcasting graphical display needs 8 kinds of colours, black, white, grey, yellow, yellowish, pale green and red.These colours are not 8 primary colours of the saturated colour of NTSC of TPU output.Need one " color conversion circuit " that TPU saturation logic color conversion is become StarSight graphical display " satisfaction " colour.This circuit is on the 2nd page of PCB sketch.Suppose that the color conversion device is made of 3 " closing 8 is 1 analog switch ".A switch that is used for each R, G, B output is arranged.This is the voltage divider of a precision, sets up desirable R, G, B voltage.Analog switch produces based on the output from TPU3 bit digital R, G, B signal via intrinsic voltage.TPU R, G, B output is programmed so that open drain electrode thereby the full Transistor-Transistor Logic level amplitude of oscillation is applicable to multiplexed analog switch.R on the 2nd page

Motorola MC1378 is as the main building block of audio video synchronization device.MC1378 is in RMOTMODE (remote mode) operation (pin one is set to HIGH) down.In this pattern, need external video to generate synchronous timing signal.1378 block diagram with reference to the 3rd page in TVRO sketch in the appendix A.
To be fed into pin two 4 to 1 1V peak-peak value ntsc video signal to be provided for 1378 and the timing information of TPU.
Signal on the pin two 4 is called as " remote video signal ".This signal in 1378 by interior clamp and be separated composite synchronizing signal.Composite synchronizing signal is used to isolate vertical synchronizing signal but also locking 4.03MHz horizontal lock ring.Composite sync (pin 39) and vertical synchronization are all applicable to externally debugging and timing.
The composite synchronizing signal that is separated is used for locking 4.03MHzPLL (using PD1), and the VCO among this PLL is made of about 4.03MHz ceramic vibrator.The free oscillation frequency of this ceramic vibrator must be used C
39Adjust.The best method of adjusting this VCO is to use a frequency counter and adjusts C
39Till frequency in U1-5 is 15750Hz.This is adjusted under the disconnection of Video In (video is gone into) signal and carries out, so VCO can free oscillation.
4.03MHzVC0 output obtains horizontal frequency after being removed by 256, and is further decoded and remove to set up " BURST GATE ".About 4 μ S are wide for burst gate (pin 5 of MC1378), and are the center with about 3.58MHz burst signal.This signal is for showing that topped is a main timing base.Be expanded for by 1378 and TPU2740 use.When starting was topped, TPU used burst gate to go to judge that a programmable counter among the TPU is used to be provided with the time-delay from burst gate to topped starting.(when+topped starting when FBLOUT descends).Any shake on the burst signal gating all will cause moving of edge-to-edge unsatisfactory on topped.
Burst signal from long-distance video is used to use PD3 to come locking 4 * colour subcarrier frequency oscillator, and this PD3 is by the burst gate gating.
The phase angle of the composite video that generates from this locality of coded portion compares with the same subcarrier frequency benchmark that is used to lock PD3.This work is undertaken by the device of PD4, thereby the subcarrier frequency phase angle of local and remote signal is in fact roughly the same.Phase-angle detection device operation summary

Long-distance video is with the AC coupling and pass through pin two 4 feed-ins, and is clamped to intrinsic DC level (blanking under the 0V).By the video feed-in fast video switch of clamp, the switch motion between the local and remote video is controlled by the Overlay Enable on the pin two 5 (can be topped).The 2nd paths guiding PD3, there, the long-distance video colour burst with compared by 4 minutes crystal oscillator frequency.The 3rd paths guiding determines that input signal is PAL or the identification detector of NTSC.
Local video produces from R, G, B signal, and these signals directly are coupled, and at pin one 4,15 and 16 input 1V peak-peak values, produces B-Y, R-Y and brightness-Y-signal after this video is through aberration amplifier (ColorDifference) and luminance matrix.B-Y and R-Y signal are by clamp and be sent to their modulators separately respectively.Modulated B-Y and R-Y signal pool together formation 3.58MHz carrier chrominance signal and send from pin one 8.This carrier chrominance signal quilt is by C

For keeping the correctness of local video amplitude modulation, in the ACC detector, compare 2 colour burst amplitude modulation and use a variable gain ACC amplifier in the local carrier chrominance signal path that takes place that both are equated for long-distance video amplitude modulation.
Absolute color SAM synchronous amplitude modulation ripple in the remote signal detector that is limited detects, and gives when deciding under the level when long-range burst signal drops to, and the carrier chrominance signal in the local signal that takes place disconnects.Clip level can be by changing the resistance R of pin 31

Table VII
The subscriber unit of nonrecognition order kind (as when newer command is performed accidental generation the in the future) must calculation command length and skip/ignore this order.
It is sign that the start byte of order has efficiently the position most, and this sign points out whether order encrypted, when being provided with, order encrypted, when removing, not encrypted.Very possible only the biography at encryption format is to show inventory, special permission and encryption key distribution order to subscriber unit.In any case will being modulated to, subscriber unit deciphers any order.
The initial compensation of the encryption section of order also is listed in each table, the great majority order is separated from the part of their contents in removing, thereby the network entity of process information bag stream can leach unwanted order and without the content of decryption command (noting, can change when actual being performed of order for the encryption compensation of order in the future).
The 2nd 2 program keys that most significant digit is pointed out to use when decryption command in the start byte of order.When this position is eliminated, use deciphering program key 0, when being set, use key 1.
Because need be, so process of commands of encryption has reduced the quantity of the required memory of memory command an initialization vector and the addition of filling character.An initialization vector is 8 byte field, and this vector is always planned the starting to encrypted byte stream in advance.Filling appended to wherein before byte stream is encrypted.The purpose of filling is to help security module to determine whether encrypted data " are altered ".Fill character fully and be coupled with to produce the original data stream length of one 8 multiple.If length begins with 8 multiple, add that then 8 are filled character.The value of filling character is to have finished the number of additional byte of padding, that is, if add 3 extra byte then each byte of padding will have value 3.Encrypted data in the order are stored as shown in Figure 9.
The further correction of this command set can append to Field Definition in the now already present order.Command processor is adjusted to ignorance, and all follow the data of the field back that in the end is identified.
Number order is addressed in the group of specific unit or unit.The unit addresses with logical address, and this logical address comprises 2 parts: 4 byte lot numbers coding and 1 byte units coding.Criticize coding and be used for, the order guiding is shared the unit group that same batch is encoded as group address.0 batch of coding has the meaning of reservation, all unit of its addressing.All all the other possible batch coding is that indexable (that is, the instruction that usefulness is criticized coding=0 transmission means the wide area broadcasting into system, only points to the unit of batch encoding in 23456 and have batch address of coding=23456.Order after unit in other batch group is ignored).
Cell encoding is used for discerning a batch discrete cell of group.Can in batch group, comprise up to 255 unit.0 cell encoding has the prospective significance of the address of all unit in one batch of group of addressing.(that is, the logical address with batch coding=23456, cell encoding=0 is that guiding is criticized all unit in the coding 23456).
The order that the subscriber unit database is set up in requirement usually sends by the reiteration shown in the Table VIII.Type of theme obtains (if not obtaining) theme subtype and obtains (if not obtaining) all the time if has authorized the unit, zone and obtain the passage inventory in zone.If the channel data passage then obtains port number in the passage inventory in zone

Table X XII
The in-house data structure of subscriber unit 52 database-driven is below described.The general characteristic of subscriber unit data is classifications.The descending of the catalog (catalogue) grade of data structure is as follows: the channel data table comprises the subscriber unit inventory of passage.Display list comprises demonstration title, description, the starting time for a passage
And the duration.Show that title comprises that the demonstration title distributes and title text.Describe demonstration and comprise display level, distribution and description text.
Type of theme and theme subtype are used to select the demonstration watched.They share a common data value (subject index), and this value is used to take out demonstration that type of theme/subtype is right of coupling.The descending of subject data grade is as follows: the selected theme display list of type of theme table theme subtype table is seen the description of Insight transfer of data fidonetFido for the description of the networking command that is received by subscriber unit.Database, storage pool general introduction
Just as by the applying portion request of subscriber unit, memory manager distributes and also discharges memory block.Application software is via handling (handle) consults memory piece.The processing of a memory block is the index to a list item that comprises pond index (pool zndex).The pond index is an address that quilt is calibrated.This address transition becomes the address of a memory block.Processing method allows the aging and decline with aims of systems and loads memory block once more, and does not need the special renewal of application data structure.
Memory manager periodically moves garbage collected and handles so that collect the memory block that is not used and they are recombined in the bigger piece.Have all memory blocks of all processing because use by the processing list inquiry, thereby the special renewal that MEMORY BLOCKS can enough application data structures and being loaded once more.In addition, storage pool can be temporarily by locking to prevent relocating of piece during the critical cycle.
Each memory block comprises as the memory block size and the object type (OBJECT TYPE) of primary part.This will offer help when all memory blocks relocate and merge.
Object type is separately in 2 main groups.Little all objects all the time can be to be defined less than 16 of memory.Current each memory block is 6 byte longs.Little all objects have their codings in first nibble (NIBBLE) object type, and the length of the piece of in second nibble of first byte of memory block, having encoded.Big object have they as the coding of first byte of memory block object type, and as the allocation units number of second byte of memory block.
If first byte of memory block and OXCO step-by-step " with " (AND) result is 0, then this is a big object, otherwise is a little object.Database storage pond access plan
The diagram of database storage pond access plan is described and is shown in Figure 26.Further Details as Follows: processing list
Processing list is the form of a fixed allocation, as shown in figure 27, comprises 2 kinds of projects: the project in free project and the use.Free project has 2 Must Significant Bit groups all the time, so that do not conflict with project in the use.
Project in the use comprises the index (this database items is inquired about via handling) that enters into storage pool for database items, for example shows header entry.The processing of a data library item is the index that enters into processing list.The pond index of a database can change owing to the garbage collected in the pond, will grow the item variation in having database but handle.Their processing is turned back to the top of free inventory from the item of database deletion.
Handle list item 0 beginning of free inventory always.Table is initialized to all the free projects with each project that comprises next index of articles.
The size restrictions of processing list can be maintained at the number of the database items in the pond.System with various port numbers will need different processing list sizes.Field description pond index be used for comprising this project first pond piece enter into the pond

Database-driven mechanism-I/O processor interface
Database-driven mechanism and I/O processor communicate via the 1M bus of 1 megabit per second speed operation.The I/O processor passes through the capable reception of the vertical blanking time data transmission network data of seldom several defineds, and sends the raw bytes that is obtained when the processor request of database-driven mechanism.The database-driven mechanism controls is by tuning channel, and specifies the special VBI that is used capable.
Database-driven mechanism sends graphics display command also for the I/O processor and for example fills up rectangle with given color, and stores or recover the pixel content of given rectangle on the fluorescent screen.All Subscriber Unit screens all are to be made of these graphics display commands.
Database-driven mechanism is that unit gives an order to the I/O processor with letter bag (Figure 43), and this letter comprises the letter packet length of follow-up seldom several orders.The I/O processor sends all letter packet bytes to the RAM commands buffer, and when transmission was finished, the order that receives in packets of information according to them began fill order.Before all command execution were intact, the I/O processor was provided with its just busy Status Flag of expression.The size of packets of information is by preceding two bytes that received in any command sequences that sends to the I/O processor all the time.Once can only send an order letter bag to the I/O processor.
Graph command
Below order be definition be connected with Subscriber Unit 52 or the television set that is combined as a whole in the needed original figure of drafting system screen operate.
Screen coordinate is the basis with (0,0) in this screen upper left corner.TPU2740 allows the X coordinate high as 503, but the maximum X coordinate of this system is 251.This just allows this system to remain on the X coordinate in the single byte and makes two pixels of different colours comprise one " system's pixel ".Therefore (251,207) are the lower right corner of this screen, and the X coordinate that is received in each order must be doubled by 2740 types.
All colours in the order is made up of two basic TPU2740 colors in the nibble up and down of color byte below.In the individual system pixel, use two separate colors to increase the number of color that can illustrate.Use two color settings system pixels in the color byte in fact to comprise along two 2740 continuous pixels of X-axis setting.
When the zone was filled up, these colors must be shaken.In other words, being used for along the 2740 continuous color of pixel of X-axis must be alternation between two colors that appropriate command color byte provides.Even number line is with color 1 beginning, and odd-numbered line (that is, the Y coordinate is an odd number) is with color 2 beginnings, and along alternation between two colors of the contiguous pixels of X-axis.
If X or Y coordinate surpass the screen scope, then 2740 graphic package will cut off output; In other words, if the operation coordinate exceeds (0,0) to (251,207) scope, then figure is not just reeled (wrap).
Order with illegal parameter value is left in the basket.Illegal " cmd type (command type) " field will cause that all subsequent commands are left in the basket in this packets of information; In other words, if IOP once left out an illegal command type, then it finishes with packets of information.Graph command has precedence over VBI and handles.
The setting figure is default
Setting the default order of figure (Figure 44) will make the I/O processor its all graphic variables be reset to their initialization value.When this database-driven mechanism just uses this order when the power supply of reset mode produces.IOP (I/O processor) with these value initializations is:
Shade width=shade height=3

Network data acquisition and control interface
System data is via the PBS network, MTV, and the demonstration time (showtime), other transmission sources on one or more vertical blanking intervals (VBI) row is received.IOP deposits the input buffer of separation in from every row (if multirow is arranged) image data and with it.Even the framing code to a certain given field is bad, data are still stored in the input buffer of IOP.In this case, 03 two bytes are stored.If this order bag comprises an order that requires response at least, then these data only are transferred to database-driven mechanism processor.
When response during a database driving mechanism request, the I/O processor will transmit that it can transmit is less than or equal to the byte of requested data word joint number more than like that.If input buffer is full, then the I/O processor begins to dump these data and becomes empty or produce up to this buffer and reset.It will make " OVf1 " flag set to a buffer of filling in the response that database-driven mechanism sends at the next one.
The I/O processor can be handled nearly vertical blanking interval (VBI) row or delegation's system data of 2 row system datas, closes 21 caption data voluntarily then.Data are all the time from two capable field collections of each system data VBI.The caption data of closing also is from two field collections.
The I/O processor responds any order that requires to respond within 10 milliseconds.

The reception group
Reception group (or RG) is that a kind of relevant channel that has that a quilt is named is transferred the entity of surveying (as-sociated channel Lineup).The reception group that three main types are arranged: broadcasting, cable and satellite.Its example is shown in the table LIV: RG typonym explanation broadcasting " SF BAY " is at SF Bay district process VHF
(very high frequency(VHF)) or UHF (superfrequency)
Receivable all channels of antenna.Cable: " TCL, Fremont can receive TCL Fremont cable system by the user.
All channel satellites to this cable (CA): the process U.S. is at the receivable northern family of northern US satellite antenna.
The Fang Suoyou channel
Table LIV
Some RGs, yes cable RGs will have the information of interest relevant with them, and sell and other work in perhaps helpful.Some examples of such information are:
The title of contact
Telephone number
Fax (FAX) number
ADI
DMA
We can say that each star vision (StarSight) Subscriber Unit is considered to one and have only a RG " member ".When it puts into practice for the first time, must notify SU, in RG, like this, it will show that it is accurate that this accent is surveyed RG for it.
Transfer and survey explanation
Transfer surveying is the actual list (catalogue) of received channel in a kind of special RG.In fact, at any given time, have a man-to-man RG and movable the accent to survey: each RG is had one and have only active an accent to survey, and for each active transfer to survey have one and have only a RG.Might be sometimes two RG the same list (list) of received channel can be arranged; Equal might one tabulation can be changed that another is then constant.Therefore, each accent survey is exactly a special RG.Transfer to survey and to be counted as usually by observing a physical map (that is map that shows TV station and cable system coverage); It comprises relevant information at the useful channel in the area naturally of transferring survey to be covered.The purpose of transfer surveying is will be defined among the given RG what channel need support with data.
Owing to defined the physical areas of cable tv and broadcasting TV, be positioned at this regional TV observer and wish that the observable channel that can receive is well-known.These channels are formed one and are transferred survey, and its requires to know to be that what table data a given RG transmits.
Concerning many LINEUP map, cover same area or overlapping be possible.This example can be to have one through the family expenses antenna to receive TV, and another one is obtained two neighbours of his information from cable.In this case, cable user should be in a RG who is different from non-cable neighbours, because he wants to receive more/different channel from his cable.In these cases, predetermined star vision (Star Sight) data of two RG of giving discharge from a PBS station, and each SU (Subscriber Unit) will wait the data that the SU that listens at it transfers definition in the survey.
Under the situation of radio and television, a given RG can comprise one to many channels, and can be included in the weak platform that fringe region has been found.Under the cable system situation, transfer to survey and defined well, and for all users in this cable system all is identical, it all is fully constant that moonwatcher's accent is surveyed all-american all observers, between the east of the U.S., West Coast, have some difference, but almost just be to cover whole one group of ConUS.

Station list
This station list is made up of some records, and the key property of a broadcasting station or satellite feed is discerned and illustrated to each record.
Be to handle not edited radio station or relay station, field is used for describing in detail the standard to the place (if having Anywhere) that obtains the radio station schedule information.Do not edited if this radio station is current, then to be set be zero to the value in this field; If use a different station designator symbol (in other words, this radio station is a relay station) that this schedule information is provided, then this field will comprise the identifier (ID) in other radio station; If (dispatch list is edited and provide data under this identifier (ID)) normally handled in this radio station, then this field is in empty state.
Station list requires to comprise with each radio station or present a corresponding project, concerning radio station or (satellite) feed, sell chief commander's data and offer star vision (StarSight), and whether in any accent of being supplied with star vision (StarSight) by the seller is surveyed, occur no matter present.This is because owing to show or the test cause that star vision (Star Sight) will be confirmed the needs to the data in a radio station sometimes.In this situation of picture, star vision (StarSight) may produce an accent that comprises this radio station in inside and survey, and only is that the request seller supplies with this schedule information.
Usually, the seller should supply with data to the local initial feed system (Local-origination feeds) in all regular schedule radio station of the U.S. and feed (system) and some appointment; This station list must comprise each the project of an identification in them, a project that is used for their each another name, and a project that appears at each feed system of arbitrary accent of supplying with star vision (StarSight) by the seller in surveying.
Other field provides this radio station and calls letter (call letter) or satellite feed systematic name, the abbreviation that this title is common, validity date and closing date (so that tackling the replacing of calling letter)
Transfer and survey tabulation
Transfer the survey tabulation to form by two kinds of record types:
The RG record
Each RG writes down the details with the relevant RG of explanation, for example as contact name, and the address, COS, save observing time or the like daytime.

Each is transferred and surveys the channel that explanation is received by RG.The combination of all current effective records of the channel of explanation in given RG comprises the accent survey (Lineup) that is used for this RG.Transferring and surveying record also may be current invalid record, perhaps because they become effectively on the date in the future, or has because their dates in the past no longer are effective.Each record comprises enough information so that the channel of in so many words discerning this RG and being suitable for, and whether (with the knowledge of current date) is used for determining to be recorded in current effective.Record also comprises the information of the structure that allows aggregate channel.
This accent is surveyed tabulation and can be transferred the renewal of survey table to be updated by incremental manner by sending one, and this accent survey table upgrades the accent that only comprises a RG who has been modified to be surveyed, and has been sent out because tabulation surveyed in last all accent.Notice that once any, the accent of a given RG is surveyed and is updated, it must fully be updated; In other words; Transfer for one and survey the accent survey that list update may only upgrade some RG, still, the RG that any accent that is updated with it is surveyed must be updated by the accent measurement information that sends all RG.
Possible use should be to send weekly to transfer completely to survey tabulation, transfers the survey list update and send one every day.
The file designation agreement
Radio station and the filename of transferring survey to tabulate are as follows with assignment:
The basic name of each file should be made up of six expressions year, months and the character of day; Basic name should be separated with suffix by a fullstop (round dot); And according to following table 55, which kind of file type suffix should represent: basic name. suffix file type example yymmdd.STD radio station every day list 940130.STD (date) file yymmdd. transfers survey file 940519.LUWLUWyymmdd. to transfer the survey list to upgrade 941121.LUDLUDyymmdd.

File content
These files will comprise the record of forming by at the Ascii text of scope 20 to 7E hex (comprise 20 and 7E hx (16 system)).To this sole exception is that record terminal character OA hex finishes an Ascii line feed.
File transfer
Radio station and the conduit of transferring the survey file to be made up of the line feed end record are delimited form (PDF) ascii text file.These files are prepared to be transferred to starsight with the electronics line mode.
Composite channel
The composite channel problem is to survey processed through toning.If single tunable channel is regularly from more than broadcast program the program source, then it is exactly that (example: cable channel #41 can show VHI daytime and show HBO or the like daytime for another part well-known composite channel for part.)
This accent survey is distributed to same " tuning " channel by the feed that each is entered composite channel and is handled the composite channel problem.The initial sum dwell time is used for being defined as this synthetic what data of editor so.
Composite channel is seldom seen in radio and television or satellite television, but is very normal for a cable supplier.
Station list (Station List)
Each record in the station list file is made up of the field of definition in table 56.Each field is delimited with an ASCII " pipeline " (7C hex) character and next field.If have that the field of the default value 0 of an appointment does not have available data then it may be in empty state; Field with the minimum value of a non-zero is enforceable.Attention: notice star vision (Star Sight), a project of this station list is left out, and a station list record is transmitted, and the result comprises data in " radio station 1D " and " date that is modified at last " field, and other field becomes empty.This signals so that stop to carry out and the associated inter-process in this radio station with regard to giving star vision (Star Sight).

This field must comprise a capitalization ascii character " R " or " S " all the time, is a RG record so that specify this record.If record type is " S ", this record is used to illustrate a special satellite so, and the meaning of some field is redefined (details vide infra).When record type=" S ", two kinds of record types all have the field of similar number, but some fields are empty all the time.2. transfer and survey record count (1-4 byte)
The decimal number of record surveyed in the accent that produces with this record: promptly: the number of record back is used for fully defining the accent of this RG and surveys.3.RG numbering (8 byte)
This numbering is unique 8 decimal number word identifiers (ID) of this RG, and RG must not number and redistributed: in case the RG numbering is distributed, it may not re-use (such as certain company stops doing business) at last; But even in this case, its RG numbering should not re-use yet.4.RG packet type (1 byte)
This transfer to survey this RG of type definition the service of what type as target;
0=radio and television (TV), this is general TV channel RG.
The 1=standard cable system, this is general cable frequency (distribution) plan.

For understanding star vision (StarSight) is important any appointed information, especially, since this information with attempt to discern a new user and be among which RG relevantly, it can help to distinguish this RG from other contiguous RG, perhaps the help people that manufacture data item feel what are ordered.20.RG this record of the date that general information is modified at last (10 bytes, numeral) GMT date and time is the record that is modified at last:
Form: yymmddhhmm; For example: 9307110514.21.RG date (10 bytes, numeral) the GMT date and time any accent measurement information relevant with this RG of transferring measurement information to be modified at last is modified at last: form yym-mddhhmm; For example: 9307110514.
Attention: numerical value " 0000000000 " is retained, and Special Significance is arranged: " this RG is not had the survey of accent can be utilized ".22. validity date/time (10 bit digital)
Following accent is surveyed to have become maybe will become effective GMT date.Be used for specifying or current effectively, perhaps also do not imitate, but become effective accent measurement information at certain known future date and time.This field specifies this information maybe will become effective date and time.23. closing date/time (empty, or 10 bit digital)
This record GMT date that maybe will stop is similar to former field, when this part when to transfer measurement information will no longer be effective, this field is specified the date and time in a future.Appointed date is assumed to be it is not comprise last minute, and the meaning is that this accent survey is the beginning in this minute, rather than stops at the end.

This explanation general introduction
Following data supplier of explanation specific definition is about arriving the television listing data delivery requirement of television broadcasting.The form of this display list of its specific definition (pipeline demarcation file).Each record format in these files also is defined.
With these file electric transmission to the details of star vision (Star Sight), and because its people are lost civilian interesting episode (nation wide program oddities) for example SyndEx need the requirement of special file and details also to be summarized.
The form of this display list record that in setting up star vision (Star Sight) electronic databank, uses by the database program that is attached to us to heavens in, and must not revise by any way or change without these forms of written permission of star vision (Star Sight) Television Broadcasting Limited.If the grammer and the meaning of employed field provide with document form in advance, then allow to use the defined field of this seller (referring to following)
The file transfer technology requirement.
File transfer medium and speed.
Use standard TLP/IP program, FTP, through a router that is connected with the leased line of a DP Ethernet and a numeral, this display list file will be transferred to the unix filesystem of star vision (Star Sight) Television Broadcasting Limited in the electronics mode.The operating rate of this leased line will be enough to transmit all data files in a reasonable time length.
File transfer protocol (FTP) and compression.
Use TLP/IP file transfer protocol (FTP) or other file transfer protocol (FTP) standard of deciding through consultation mutually, these data will be transferred in the unix filesystem of star vision (Star Sight) Television Broadcasting Limited.Because this batch data is to use a kind of that decide through consultation mutually transmit with our data compression algorithm of unix filesystem compatibility, therefore, this document may need compression.
The file transfer details
Finished in the past at 8 o'clock of PST (Pacific standard time) simultaneously along with this document is transmitted in, this document 7 days weeks, will be transferred to star vision (StarSight) on the every day basis.File transfer will enter in family's guide (home directory) corresponding with the registration name that is used for carrying out this document transmission every day this.
Should " master " file download to star vision (Star Sight) and will be all the time that date enters future after 12 days.Therefore, if be No. 10 today, then to download will be zero-time in the beginning at zero point of No. 22 GMT (Greenwich Mean Time) to the data of today.
(this explanation in referring to following GMT specification requirement)
Because this data file sent on the basis in every day, thus some mechanism must be in place so that get ready for the renewal of the listing that has been transmitted.It is finished through " renewal " file.Because the final updating file produced, so a transaction file comprises the record that all have changed, this transaction file will be revised still any data on any date of " activity "." activity " date is defined as since the date of today and crosses over 11 days later date (in other words, all are from now on to by " master " date that file covered of today, but do not comprise the date on that date).
The service that one class is performed will require " to upgrade (Flash update) fast; This class service 5 minutes planted agents entering any variation project after provide the file of " renewal fast ".This file whole day strides across leased line and " moves lentamente " to starsight.
The display list file is introduced
Star vision (Star Sight) Television Broadcasting Limited operation a kind of with special form transfer of data to the user's data network of all-american star vision (Star Sight).These data are used for constituting a kind of " program guide on the screen " that is called star vision (Star Sight), and star vision (Star Sight) can make its user watch TV program list on their the TV screen by the man-machine conversation mode.The information of this network originates from star vision (StarSight) database that is built up by the computer program on the UNIX computer that operates in us.For building up this database, need data to provide manufacturer to supply with star vision (Star Sight) with the rendition list file that is called the display list file.
GMT
A display list file is the record of one group of TV program list that chronologically successively sorts.Star vision (Star Sight) need comprise the display list file at first record of the zero-time of 0000 hour GMT with it, or first demonstration that need begin later at 0000 hour GMT.Therefore, first record in each display list file will appear at first demonstration of GMT midnight or GMT small hours, and the last record of a display list file should appear in 24 last demonstrations that begin later on of GMT.
In other words, given master file will only be included in the beginning of GMT0 point and at the record of all program originators of one day of GMT24 point end.On the contrary, master file must comprise all demonstrations of all program originators that day:
Summer time
Because " zero-time " of any display list record provides in the time limit of GMT all the time, therefore, this data supply manufacturer is warned, 1 year summer time must be considered secondary, once was in spring, asked the summertime at that time, and once in autumn, turn back to the standard time at that time.This time modification must all take place all program datas and all program originators (PO), unless PO lives in a non-summer time state or area.Summer time will make DP that record is edited or is transferred in the PO file, and this document is for regulating 1 hour forward in spring and regulating 1 hour in autumn backward and all proofread and correct.
This display list record has been adjusted to GMT in case note that the demonstration time, even also should be no gap or non-overlapping connection on the transition date in summertime all the time.
SyndEX and network exclusivity
Because FCC rule (regulations), a TV cable supplier is required program (under the request situation of local station) is planned, this program is directly clashing aspect time of the program that comprises a spot broadcasting TV radio station and the content.This may make this cable supplier remove to replace program on that channel in the conflict time.In order to show the correct scheduling of the time slot that is used for this planning, must be with a SyndEx rule notice star vision (Star Sight) before this planning earlier than 24 hours.
The motion cancellation
Because the FCC rule, if a given percentile admission ticket can not be sold in sport events 24 hours, then a motion event may be from local TV coverage cancellation.Star vision (StarSight) needs this cancellation aspect knowledge.
Composite channel
Some cable supplier is divided into the Polymera section with a cable channel, in the different time, inserts the program from the program originator more than two or two in a channel.Require DP to provide star vision (Star Sight) on a such channel with the information what service gets across in any given time be.This information will be provided in the PO of the channel that is used for wherein occurring synthetic program tabulation.
Many PO information of this composite channel is processed by " RG listings format technical specification " explained above.
The area access channel
This FCC requires each cable supplier to support a regional access channel (CAC) to be used for public use at least.The public that private citizen can ask Pgmtime to be used for them on this channel watches, public information or approved public program.
Star vision (Star Sight) requires a display list file that includes the programme information of each CAC, and this CAC display list filename is subjected to the constraint of this cable system name simultaneously.
Low-power radio station LPTV
Low-power (great majority are privately owned) broadcasting TV radio station exists in many areas of the U.S..Ask for something in these low-power radio station is by the rendition list that DP supported.These the rendition lists will each LPTV is contained a display list file processed on the basis by the station.
Prepare with thinking SyndEx network exclusivity, sports are cancelled, and composite channel, regional access channel and low-power platform provide the accurate form of data to determine.
The display list document definition
Listing file is made up of the many records that comprise TV program list.This display list record has the section of a fixed number.Most of fields are fixed ranges, and the minority field is a variable range.So just give a display list minimum of record and a maximum byte scope.Referring to (the display list record field definition of relevant accurate minimum/maximum (MIN/MAX) scope.)
Except record end end mark, outside the OA hex (line feed), this display list file will only comprise ascii character, and only 20hex to 7Ehex contain 20 and the scope of 7Ehex in.So just got rid of any control code, the line feed code or the record end sign indicating number of the part of any display list file.
The display list filename
The file of being discussed in this explanation has three kinds.They all have the identical recordings form, but use difference are arranged slightly.They are known as " master " file, and " renewal " file and one give " fast " file of fixing the date.Master file only comprises the data of a technical dates.It equals the initial load of all data on this date.This transaction file comprises the information of the display list data that correction is provided on date earlier, and it comprises and just may comprise and relevant data on the some different daytimes of having imported some fresh informations.This rapid file comprises the lastest imformation that just has been transfused to.
This root name should comprise the numeral that connect for 4 bit representation dates behind the letter " MAIN ", and [choosing wantonly] then is a round dot and suffix " DAT ".For example " MAIN0812.DAT " is an effective root name, is " MAIN0812 " therefore.
This transaction file name connects 4 bit digital of representing the date after should comprising letter " UPDT ", and [choosing wantonly] then is a round dot and suffix " DAT ".For example, UPDT0812.DAT is an effective transaction file name, as " UPDT0812 ".
The rapid file name should comprise the numeral that connects one time of 4 bit representations behind the letter " FLSH ", and [choosing wantonly] then is a round dot and suffix " DAT ".For example, FLSH0642.DAT is an effective rapid file name, as " FLSH0642 ".
Because the interface to dissimilar computer systems is certain, work effectively with existing any computer operating system so this document naming convention is chosen.In this document name the letter or all be the capitalization or all be small letter; Do not allow the mixing situation to occur.
Each PO data will have its own intrinsic file part, and this document partly is to discern by doing sign in the 1st field of each record relevant with this PO this PO.This identification number (being no more than 12 bytes) will include only 0-9 bit ASCII numeral, and will with distribute to this station list file in station designator symbol (ID) numbering of this PO identical, ID numbering in this radio station is defined in an independent document.
The display list file size
As in another place definition of the document, each file will comprise the display list record.This document will comprise requirement and fill out 24 hours so much records of one day enough.
All there is one as the program length defined in " runtime (running time) " field and one " Starttime (zero-time) " at each record in the given file as in the zero-time field of this display list record, defining.These zero-times are connected in one day 24 hours with the content that will make a file running time, do not interspace in this sequential.
Threaded file
All " master " file loggings will have one day one day zero-time that is connected and the running length with week Monday etc., and without any the time space.

The display list field grade explanation that is described in detail.
This display list record field is divided into 4 grades.They are data fields, and this data field comprises programme information, separate the delimiter field of data field, and end record also will be write down the end-of-record delimiter that separates with the EOF end mark.
The explanation of field grade.
Notice that all fields all have minimum and the maximum magnitude by the byte explanation in the specification requirement below.Most of fields are regular length and the length that must not violate defined.Other field has a variable minimum and maximum length, and the minority field is defined as minimum or maximum length.Even a length field of having fixed comprises insignificant data, it also must complete its minimum length with suitable character.Largest field length also must be observed and whenever not have field to be allowed to surpass its maximum length.
The data field text.
This style that is included in any field will not comprise control code, and all fields only are included in hexadecimal numerical value 20 to 7E, comprise 20 and the scope of 7E in the ascii character group.
Delimiter
This byte character is pipeline " | " (the pipeline ASCII character is 7C hex).It separates the different field of display list record, and it is unique in a display list record, and will be not used in other place of this display list record except making delimiter.There is identical number in delimiter with data field.This display list record has FIELD, DELIM-ITER.., FIELD, DELIMITER, END OF RECORD pattern.A delimiter is followed the last data field appearance of any record.
Record end
All records will stop with the end mark of a record end, and this end mark is followed the last delimiter back of final data field in a display list record.This end mark is line feed (OA hex) ASCII character, or carriage return (OD hex) ASCII character, perhaps two ASCII character that occur together with any order.
The end of file
The end mark of the end of file is defined as text-string " ZZZZZOF ".The final data record of a display list file must so that all data of signaling have sent finish succeeded by the end mark of an end of file.
The data field explanation that is described in detail.
(1-12 byte) this radio station ID is used for unique number (being distributed by data supply manufacturer: see this radio station list record format) with reference to this program originator (TV radio station, cable channel or satellite supplier).It is never greater than 10 ten's digits.Other character does not allow to use.2. from date
(8 byte) describes the 8 byte numbers on the GMT date that this program will broadcast.(year, the moon, day) this date must be identical for all records in the given file.Byte 1-4 defines this year, for example: 1991.
(4 byte) 4 byte codes are this programm broadcasting time GMT, and as military time input.

(5 byte) this 5 byte number will be from 00000 (for no program connection) to 65535 (connecting for reaching 65535 unique programs).This number allows to be used for unique grouping of two or two above particular program or demonstration, this program or show may need to link together and be used to write down purpose.There is not the recording occurring continuously of the program of same title name as ROOTS1 and ROOTS2 to need being connected of these programs or grouping for those.If not having program to connect this field will be 00000, and if connection arranged, then unique decimal system number of this field nearly 65535.This unique number is held up to the program that is connected and has finished and any demonstration of including with reference to this number disappears from this database.After that time, this number can circulate and be used once more again.Do not make stipulations on nonvolatil basis to packet ID coding of any demonstration locking.
Because this number is converted to 2 byte binary numerals by star vision (Star Sight), and sends to SU (Subscriber Unit) by this way, therefore need this upper limit 65535.
If not conflict on writing time, then this number can be used for crossing over the channel boundary and be connected one group of demonstration more than two or two on two or two the above different channels as a group.11. title

Following all fields after " PPV incident " all is option field (except the end mark of enforceable record end).Do not stipulate the minimum or maximum numbering of these fields, as for the not special by force boundary of the number of characters in any one field of these fields.
The seller uses this part of this record so that the additional data that relates to this demonstration is provided, and the form of its defined may make this demonstration become and have any problem and maybe can not transmit.The defined field of each seller should be used for illustrating a data element.
Field contents is a free-format, though described restriction before having, promptly in vertical bars (hex7C), carriage return (hex 0D), or under line feed (hex 0A) situation about not occurring as data, all data must be transmitted as printable ASCII text, because these characters have " field delimiter (vertical bars) and " Special Significance of record end (carriage return and/or line feed) respectively.
This purpose plans to allow the seller that this demonstration as far as possible freely is described.Relevant display type, additional informations such as style, kind, subclass can be placed in these fields, and the information of current other type that may not reckon with also can be placed in these fields.If these fields are used, the seller must provide a kind of file for individually star vision (Star Sight), and this document as far as possible fully defines these fields and how to be used by the seller.
The example that is adopted is not that attempt is used for stipulating one group of form, and it only is the defined field of this seller of explanation can be replenished out of Memory in this record an a kind of possible method.In this embodiment, we suppose that except the classification of stipulating, this seller also has the available classification about (physical culture) movement display in normal format.This seller must give information for this field from these data itself individually: such as, seller XYZ provides a kind of file that comprises following information for star vision (StarSight): meaning SPNAME Name of SportSPENV " Indoor " or " outdoor " SP$ " profssional " perhaps in the field name, " Amateur ", or " pro-AM " SPLIVE if present, game is being Carried live.SPTEAM if present, this is a team sport. notes: about the grammer in the defined field of being supplied with by seller XYZ of seller: " field name " is a continuous ascii string from above tabulation (not allowing space or mark).Mean " very " state in the existence of this field name in some cases; In other cases, except that this field name, also specify a value.If a value is designated, then connect a space or mark behind this field name, and other anything else comprises its value in this word.
Given this information, the defined field of seller of example below seller XYZ can look like to a record transmission of star vision (StarSight) now: field 68 SPLIVE that field 67 SPTEAM the 5th seller of field 66 SPENV outdoor the 4th seller definition of field 65 SP$Professional the 3rd seller definition of field 64 SPNAME Field Hockey second seller definition of first seller definition defines
Notice that for example, even SPENV is designated in the field number 66 of this record, it also can be defined or not mention in the defined field of any seller.Same observation is used for the defined field of all sellers.Because in this example of composing as data to this field name, used this method, so it is genuine.If the seller has selected to adhere to more strict agreement, according to this agreement, no matter whether this field exists data, each field can occur all the time, each field name or the usage position that may place one's entire reliance upon so, and can be formed file individually, therefore, just can save needs with the transfer of data field name; Any can acceptance in two kinds of methods, and if seller's another kind of method of having them to like, this also may be accepted, as long as it is said in the described in the early stages rule.
An example segment of above display list record field is as follows:
SPNAME?Field?Hockey|Sp￥Professional|SPENV?outdoor|SPTEAM|SPLIVE|
Record end (line feed hex OA) and/or (carriage return hex OD)
Record end of mark.Transmission will allow the flexibility of definition for the text between dissimilar computer systems.
Record end
After the last data record in a file, the seller must add a special file logging and finish, and it is defined as beginning with text character string " ZZZZZEOF ".After connect the record of (may with seller's define field insert) record end.When star vision (Star Sight) wished to read a call sign value (call Sigh Value), its software will run into this text-string; The value of being read will be carried out verification with respect to this value that is saved, if they are complementary, star vision (Star Sight) software will stop to read of this document.
The more important thing is that this text-string also will be used for finishing of a file transfer of verification.If a new file appears in this data input directory, Input Software will be checked this symbol in the last record of this document so, if this symbol is undiscovered, this transfer of data or die young at middle stream is not perhaps also finished so; In both cases, begin to import data and remain inappropriate.
Notice that the definition of this record is exactly to end up with record end with the ZZZZZEOF beginning; The remainder of this record can be defined by the seller in the common restriction range for the defined field of seller.Here as useful additional (replenishing) information may comprise a kind of in this document the counting of record count, date of manufacture/time, a kind of station list that goes wrong, or any other seller thinks relevant brief information.
