This designation data includes: the sector number, each segment number, transponder of representing the total sector number of time, the representative of date, the current time of representative in current period be number corresponding to transponder table and channel table under each segment number situation, and this table is the directory that the stem at each channel is taken by this section.
Following this designation data, is that preface is arranged channel data with section 1, section 2, section 3 or the like.In each section, arrange the channel data item of predetermined number.In this embodiment, respectively with the data placement in channel 1 and 2 at section 1, the data placement in the channel 3 and 4 is in section 2.
Each channel data contains the channel number of representing channel number, represent the channel name of the ringing number (title) in a broadcasting station, be used to discern the ID data of the logos in a broadcasting station, be used to discern the ID data of MPEG video data and mpeg audio data, represent the program number of the channel program numbers that this channel (for example channel 1) has, (for example be offset with first program of representative from the deviant of the stored position of top line data (address) of a predetermined channel, under the situation of channel 2, the beginning of a program segment (beginning of program 1-1 under the situation of Figure 12) is until the stored address of initial program data of program 2-1).
In addition, program data comprises: the program description of representing the grade of age limit of the book of final entry of program title, the time started of representative broadcasting time started of program title, the time span of represent Pgmtime length, the classification of representing programme variety (classification), representation type (classification) and subclass, representative program and program detailed content (for example, decoded data condition, this program are whenever to watch the coding of once paying once).
This program data is arranged in the summary of each section.In such an embodiment, the program data in section 1 comprise in eight channels 1 such as program 1-1 to the program 1-8 data and seven channels 2 in such as the data of program 2-1 to the program 2-7.
Figure 13 schematically shows until the screen that is used for general indication and is displayed on data processing on the monitor apparatus 4.
CPU29 is provided with the transport address of importing from the data of front end 20 among the register 24a in demultiplexer 24 in advance.Then be temporarily stored in earlier later on the Data Buffer Memory 35 from front end 20 data feeds, these data are read and are sent in the transfer address that is arranged among the register 24a from demultiplexer 24.
As mentioned above, each packet is coupled with stem.Multiplexer/demultiplexer 24 is with reference to this stem and present the MPEG video data to mpeg video decoder 25.Multiplexer/demultiplexer 24 transmits the mpeg audio data to mpeg audio decoder 26 then.When ID data that are contained in stem when being indicated numbers according to, channel data or program data, these EPG data are stored in a presumptive address among the EPG district 35A that is arranged on register 24 then.In this way, the EPG data are stored among as shown in figure 12 the EPG district 35A.
In addition, when this transmission was finished, owing to no longer need, this stem was dropped.
In this mode, when the EPG data were stored in the capacity of the EPG district 35A that for example has the 120K byte, the whole status signals of multiplexer/demultiplexer 24 outputs were to CPU29.When receiving control signal, the suspend combination of EPG data of CPU29.After this, when showing EPG, carry out the decoding processing such as expansion, classification decode operation of compression EPG data.
In this mode, when the EPG data from the current time, for example 200 channels were incorporated into EPG district 35A after 4.5 hours, these EPG data (designation data, channel data and program data) can receive from any transponder.That is to say that identical EPG data send in any transponder.
Next, CPU29 prepares classification table 230, and data and this classification table of being used for retrieving from the EPG data that are stored in EPG district 35A in the predetermined channel are stored in (preparation of this classification table is handled and will be described in detail in conjunction with Figure 14) among the SRAM36.This classification table 230 was corresponding to all EPG tables 240, and all channels (for example, 200 channels) that are used for from the current time were retrieved each program later on until 4.5 hours.
CPU29 from all EPG tables 240 each channel of predetermined display region 250 (in 7 channels, for example, below Figure 19 will be described in) scheduled time scope in (the current time after,, will be described below) at Figure 19 until 1.5 hours read program data and these data of reading are written into DRAM 25a as the bit mapping (enum) data OSD district 25a from EPG district 35A.Mpeg video decoder 25 is read the bit mapping (enum) data among the OSD district 25aA and is output the data to monitor apparatus 4 then, so that such as general indication (Figure 19) or similarly indicate EPG to may be displayed on the monitor apparatus 4.
When character etc. was shown as OSD, the character data that is stored among the EPG district 35A was compressed, and this catalogue is used to carry out common process.Therefore, ROM37 store compressed code conversion catalogue.This compressed code conversion catalogue comprises syllable catalogue and word catalogue.There are a kind of syllable catalogue and three kinds of word catalogues that prepare.
Each word is related to the number of the kind of representing three kinds of word catalogues and is designated as 0,1 or 2 by two the byte data representatives and first byte.Beyond two byte datas, previously prepared word is that mode that saves word of preface residue is arranged with 0 to 255.When the encoder at transmitter side sent predetermined word, this word sent with this two bytecodes.In ROM37, preparation and the identical catalogue of this conversion catalogue for preparing in coder side, it is original word that this conversion catalogue is used to make multiplexing two bytecodes.
In addition, when transmitting the word that character rather than transmission prepare, can transmit a word in conjunction with a kind of predetermined bite in pre-prepd 252 kinds of bytes.This byte is with a hand joint representation.
ROM37 utilizes the memory location of the bit mapping (enum) data of character code and graphemic code to store the table (address mapping table) of a correspondence.By with reference to this map table, can be read out and write OSD district 25aA corresponding to the bit mapping (enum) data of predetermined character code.Certainly, ROM37 stores this bit mapping (enum) data a predetermined address.
In addition, the ROM37 storage is used for the logos data of explicit identification language.At the same time, ROM37 storage is used to access logos ID and corresponding to the address mapping table of the logos data of this ID.When being stored in corresponding to the logos data of the address of this ID and writing these data to OSD district 25aA during with logos ID zero clearing by reading, the logos in each broadcasting station can be displayed on the monitor apparatus 4.
In addition, the classification table that is stored among the SRAM36 is the preface preparation with the channel number.Be used to utilize specific channel of extraction or program or alternative these order such as a kind when this classification table, this classification table is write again.Yet as mentioned below, this classification table is the table of the positional information (pointer) of a memory channel and program data.The pointer of program data and channel data constitutes one group.When this program data and channel data were rewritten, these data changed by one group of unit.
Figure 14 represents to be used for preparing the processing example of a classification table that will inject SRAM36, for example, suppose 4.5 hours EPG in 200 channels, the minimum time of each program is set to 0.5 hour (30 minutes), so that maximum 9 programs can transmit in a channel.Therefore, the individual program in maximum 1800 (=200 * 9) can utilize 200 Channel Transmission.Like this, in processing example shown in Figure 14, the number that this category is not shown is set to 1800.
In beginning, step SP1, variable N is initialized to 0.Then, variables L is initialized to 1.This variable N represents one group of number (address) of classification table.For example, suppose one group of number of 0 to 1799.In addition, variables L is represented the number of channel and any value that is assumed to be in from 1 to 200 scope.
Next, processing advances to step SP2, in the address of SP2EPG district 35A (PC1 in this case) corresponding to channel number L (channel number is 1 in this case) as the pointer of the channel data of the address N (at this situation N=0) of the classification N of SRAM36.As a result of, address PC1 is set at the EPG district 35A of channel 1 as the channel data pointer of address 0 in this case.
Next, handle to advance to step SP3, obtain skew of first program joint and program number from the channel data of channel number L at SP3.This first program skew is used to retrieve program L-M at step SP5.
Processing proceeds to step SP4, and initializing variable M is 1.This variable M representative is set to the number of programs the same channel of any value of from 1 to 9.In addition, at step SP5, an address among the EPG district 35A is corresponding to an address N (in this case, the program L-M of the pointer of N=0) program data (in this case, program 1-1) of conduct in the classification table.Therefore, in this case, the address PP1-1 among the EPG district 35A of program 1-1 is set to the pointer of the program data of address 0.
Next, handle to proceed to step SP6, judge whether that at SP6 variable M is a number of programs or greater than number of programs.When variable M in same channel less than number of programs, handle to advance to step SP7, variable N and M are added 1, thereby N=1 and M=2 are provided.In addition, at step SP8, be set up as the pointer of the channel data of address N in the classification table (being address 1 in this case) corresponding to the address PC1 among the EPG district 35A of channel L (being channel number 1 in this case).
Then, handle and to advance to step SP5 and processing is after this carried out by same procedure.
By the reprocessing of step SP5 to SP8, the pointer of PC1 conduct channel data as shown in figure 15 is stored in the address 0 to 7 of classification table.In addition, the program 1-1 in EPG district 35A is used as the pointer storage of the program data of address 0 to 7 in the classification table respectively to PP1-8 to the address PP1-1 of PP1-8.
When above-mentioned finishing dealing with, M equals number of programs at step SP6 judgment variable.At this moment, processing advances to step SP9.Judge whether variable N greater than 1799 at step SP9, or corresponding channel data does not exist.When these conditions do not satisfy, handle and advance to step 10, so that variable N and variables L add 1.In this case, N is set to N=8, and L is set to L=2.
After this, handle and return step SP2, repeat identical processing.Therefore, as shown in figure 15, PC2 is written into the address 8 to 14 of classification table as the pointer of channel data, and PP2-1 is written into respectively as the pointer of program data to PP2-7.The same procedure of this reprocessing is carried out.
Next, by with reference to flow chart shown in Figure 16, explain that following monitor apparatus 4 shows the example of a processing of general indication.At step SP21, the predetermined button switch that begins to judge whether to shake control instruction device 5 is operated and waits for until this switch and is operated.
In other words, when detecting a predetermined button via the main body 161 of push-button switch matrix 82 or selector button switch 131, the CPU72 of remote-control command device 5 is operated, LED76 is operated through led driver, exports an infrared signal corresponding to the push-button switch of operation.
The CPU29 of IRD2 receives the input of these infrared signals through IR receiving unit 39, from which push-button switch of this input-signal judging remote-control command device 5 has been operated.
Then, judge it is that this predetermined button has been operated, handle and advance to step SP22, judge whether that at SP22 the button of this operation is a menu button switch 134 at step SP21.Be operated when being judged as menu button switch 134, handled advancing to step SP23 and CPU29 execution menu demonstration processing.
In other words, CPU29 write the bit mapping (enum) data to for example as shown in figure 17 in corresponding to the main menu among the OSD district 25aA of the DRAM25A of the EPG data that are stored in EPG district 35A (program designation data).This bit mapping (enum) data is read from DRAM25aA and is input to NTSC encoder 27 from mpeg video decoder 25 then, will be transformed to the data of NTSC method.These NTSC method data are sent to monitor apparatus 4 and are used as S vision signal or composite signal via 11 demonstrations of AV line.
This cause the main menu of Figure 17 to overlap onto receiving this moment with the channel image that shows on, as shown in Figure 8.This menu is displayed on the CRT4a of monitor apparatus 4 as a window then.When in the data in the predetermined window viewing area are being utilized the processing procedure of decoding processing of video data of MPEG method compression, being read out, by from the OSD district 25aA of DRAM25aA, read and export a bit mapping (enum) data realization for each cycle.
In the main menu screen as Figure 18, window is split into 9 districts, so that in order to select the icon (soft key) of predetermined pattern the Show Button with each district.The user by have directivity ground operation selector button switch 131 can moving cursor on any direction of eight directions of horizontal plane (in this embodiment, the predetermined button figure has brightness color or the flicker different with other buttons to be revealed as cursor, with under situation as shown in figure 18, cursor is to be positioned on the button icon of general indication).
For example, when this selector switch 131 worked in the left of general instruction button icon, cursor was moved to the button icon of other indication.Therefore, when selecting switch tiltedly to face toward the lower left to work, cursor is moved to the button icon of motion indication from the button icon of general indication.
For example, when selecting push-button switch 131 only can be operated at upper and lower a, left side and when right, for cursor from the button icon of general indication with to the button icon of motion indication, cursor need temporarily be moved to the left side and be moved on to downside then, or temporarily moves on to downside and move on to the left side then.In other words, in this case, need twice operation.Simultaneously, when whole device is configured, so that this selector button switch 131 be can operate in angular direction and upper and lower a, left side and right four direction the time, this cursor once just can move to the button icon that motion is indicated from the button icon of general indication.
The user selects predetermined pattern by moving cursor on the predetermined button icon, carries out selection operation (vertical operation) by vertical pressing selector button switch 131 then and determines this selection.
At step SP24, the button icon of total indication is selected as judging whether this selection is determined.Total indication the button icon selected and when being be sure of, this processing proceeds to step 25, handles with the demonstration of carrying out general indication.The processing of detailed total indicated number will be described with reference to Figure 21 in the back.
Judge that in step 24 this processing proceeds to step SP27 under total non-selected situation of button icon of indicating, to judge whether to have selected other button icon.When this button icon was not selected, this processing turned back to step SP23, continued menu and showed.
Under the selected and definite situation of the button icon of step SP27 judgement except that total indication, handle proceeding to step SP28 then to carry out processing corresponding to selected and determined knob icon.
On the other hand, when step SP22 was not the operation of menu button switch 134 from remote-control command device 5, this processing proceeded to step SP26, was operated to judge whether instruction button switch 143.Judging that this processing proceeds to step SP25, to carry out the processing of total indicated number under the instruction button switch 143 operated situations.
Simultaneously, when the button of step SP26 judgement except that total instruction button switch 143 was operated, this processing proceeded to step SP28, to carry out the processing corresponding to operated push-button switch.
As mentioned above, this total indication can be shown by menu, also can directly be shown by operation instruction button switch.
The total indicated number processing at step SP25 that is shown among Figure 16 is performed, so that be shown in the OSD zone 25aA that the bit diagram of the total indication among Figure 19 is written into DRAM25a.This bit diagram is read out from mpeg video decoder 25 then.This bit diagram with that time with the visual overlaid in demultiplexer 24 selected broadcast channels, and be shown as shown in figure 20 a window.
In the total indication shown in this embodiment, vertical axis is used as channel axis, and the call-sign of each broadcasting station (broadcasting station name and channel number) is shown.Trunnion axis is used as time shaft, and the airtime is shown.In the precalculated position of two axle defineds, the title of this program is shown with matrix-style.In this embodiment, the programm name in seven channels from one and a half hours present time is shown with each channel.When the selector button switch of remote-control command device 5 was directed and is operated, the cursor 212 that shows with different brightness (becoming clear) and color just moved on to the button icon of operating corresponding to this direction.
Details will provide hereinafter.In total indication shown in Figure 20, the program name area that shows in matrix (in lattice) mode will be called as programm name viewing area 220.This programm name viewing area is corresponding to as shown in figure 13 viewing area 250.Then, in the scope of this programm name viewing area 250, according to (for operator's distally) on the selector button 131, down (before operator's the root), and the direction of a left side and right is operated, and that cursor 212 moves to respectively is upper and lower, a left side and right.
Here, when selecting push-button switch 131 when cursor 212 is moved in the state of upper and lower, the left side of programm name viewing area 220 and right-hand member by directed and operation further, the displaying contents of this programm name viewing area 220 is by scrolling.For example, when cursor 212 is located in the most descending of programm name viewing area 220, and selector button switch 131 is when being directed and operating than the below, and the displaying contents of this programm name viewing area 220 is rolled up lastrow.Then, because cursor 212 stops at the next line of the whole EPG table 204 of specifying EPG as shown in figure 13, so cursor 212 is by line down.For upper and lower to left and right direction, this displaying contents with the same manner by the ending of scrolling up to EPG table 240 time.
Further, selector button switch 131 can be directed and operate in upper left, upper right, lower-left and lower right to and eight directions of upper and lower a, left side and right four direction.Cursor above-mentioned moved and can operate in eight directions according to eight directions of selector button switch and be operated.
As operation for eight directions of the selector button switch 131 of moving cursor 212, sequence of operations with the vertical operation of the selector button switch of selecting for the program of be sure oing cursor continued operation location 131, can only be with a thumb, and different hand of no use maintains this remote-control command device 5 and improve the possibility of operation.
Here, when the cursor key with four direction and selector button remote-control command device are used to realize operation that same cursor moves, are selected up to program and are accompanied by a plurality of operations.
For example, as shown in figure 20, in order to move the left lateral be presented at fourth line programm name viewing area 220 (rectangle region is represented the programm name of 9:30 to 10:00 in TBS 233) to the most descending right lateral (rectangle region is represented the programm name of 10:30 to 11:00 in SCFI233), following cursor key by by three times and left cursor key by after by twice, this selector button must be pressed.Therefore, need push altogether six times, the button of at every turn pressing is different, so this remote-control command device must be held with different hands.
Afterwards, replace the cursor key of above-mentioned four direction, consider provide from all directions to cursor strong.Therefore, in this case, need to obtain a big used area on the guidance panel of this remote-control command device, this has just hindered the miniaturization of remote-control command device itself.Further, owing to arranged more button, just inevitable push-botton operation is worsened.
In this embodiment, when selecting push-button switch 131 when eight directions are directed and operate with thumb arbitrarily, selector button is as the cursor key at eight direction moving cursors 212, thereby this selector button is used as for a selector button that obtains the program selection with thumb by the vertical operation of select button switch 131.With continuing, can hold remote-control command device with different hands from the sequence of operations that moves to the program selection of cursor 212, only use this thumb just can be operated at any time.
According to aforesaid total indication, the title of EPG (total indication), the logos of current institute channel selection (broadcasting station), the content of program and current date can both be revealed.
Figure 21 shows in the detailed total indicated number processing of step SP25, in the beginning of step SP40, for the channel image is transformed into the setting of the still image that is received in the register of mpeg video decoder 25, is finished by CPU29.Being provided with of still image can be then by read a memory outside the buffer storage 0 in the buffer storage shown in Figure 11 2, so that do not upgrade this buffer storage.
Then at step SP41, fixing content displayed, as the regulation row of total indication, variable content displayed is written into the OSD district of DRAM25a as zero-time and call-sign.Then at step SP42, be initialized to 0 corresponding to the variable N of classification chart address.Then at step SP43, be shown in 7 call-signs (channel) of the total indication among Figure 19 and expression and be initialized to 1 corresponding to the variable L of capable number of the programm name of this mark.
At step SP44, the channel name character string of compression is read out according to the channel data directive in the address N of SRAM36 kind table then, so that recover original character string with reference to compressed code conversion book and the character code/bit diagram map table that is stored among the ROM37.
Further, the bit diagram data in character string (channel name) are determined, and are written in the channel name item in L capable (first row in this case) among the OSD district 25aA.For example in the embodiment shown in Figure 19, channel name " TOON " is written into.In the same way, this channel name also can be written into channel number.In other words, number " 227 " corresponding to " TOON " are written into.
This processing proceeds to step SP45 then, and at that, time started and time span are read out according to the directive of program data in the address 0 of kind table.At the coordinate position corresponding to time started and time span, the button icon (its data also are stored in ROM37) that is used for the program selection also is written into.Further, this programm name is read out and the character string of programm name is passed through with reference to the compressed code map table, and character code/bit diagram map table is resumed.Further, these bit diagram data are determined and write on the button icon.In this way, " TOON " is written into from the programm name of 9:30PM to 11:00PM broadcasting.
This method proceeds to step SP46 then, and is stored in button icon coordinate position that step SP45 writes and the channel data in SRAM36, and prepares when user's program is selected subsequently.
As mentioned above, be written into OSD district 25aA up to being judged with programm name at capable call-sign of step SP47, variable N just increases by 1 at step SP50, and at step SP44, SP45, SP46, the annular processes of SP47 and SP50 is repeated.Writing of delegation is fashionable when having finished in step SP47 judgement, and variables L is increased 1 (variables L is set to L=2 in this case).
At step SP49, judge whether that variables L equals 8 (write operation that judges whether 7 channels is done) then.Because variables L is changed to L=2 in this case, so after the address N of corresponding top line of go (channel) subsequently was provided with, this processing turned back to step SP44 and follows reprocessing.
Like this, these seven call-signs and programm name are written into by the processing of repeatedly carrying out at step SP44 and SP51.When this write operation is done, judge that at step SP49 symbol L is given as L=8 and this processing is done.
In addition, in processing shown in Figure 21, for simplicity, displaying contents is omitted.In fact, all information projects, as character, logos etc. all are written to OSD district 25aA.
Then, with reference to flow process shown in Figure 22, in the state that total indication shown in Figure 20 is shown, provided the explanation of the processing that is used to select a scheduled program.The user specifies and selects selector button switch 131 with the place of moving cursor 212 to the button icon that writes the scheduled program title.When program was selected to be determined, this selector button switch 131 was by operation (selection operation) vertically.
In the beginning of step SP61, this method is in wait state, up to finishing some inputs from remote-control command device 5.Then, when input is done, handle proceeding to step SP62 to judge whether that this input is the selection operation input.When input was not the selection operation input, this processing proceeded to step SP64 and is performed to judge whether the direction operation.When judging that this direction operation is not performed, the push-button switch except that selector button switch 131 is operated, thereby does not have specific operation to be performed and to turn back to the input of step SP61 wait from next remote-control command device 5 in this case.
When judging that at step SP64 the designated and operational processes of selector button switch 131 proceeds to step SP65, a processing is performed so that at the direction moving cursor 212 corresponding to operation.In other words, this bit diagram data writing position is changed and is the button icon corresponding to 131 operations of selector button switch.
Then at step SP66, the program transponder on the button icon of cursor positioning number is obtained.This transponder number can be obtained by specify a segment number from the channel table of designation data, thereby determines transponder according to this segment number.Further, the data ID of program is read out from the data ID (Data ID) of channel data.
This processing proceeds to step SP67 then, is shown to judge whether this program, even also like this when this program is sponsored program.A predetermined message is shown on the CRT 4A, so that being or not determining by each input.This has just made the whole operation complexity.Then, for example when IRD2 was obtained, it was tentatively imported, so that determine when this program is sponsored program whether this program is shown.This preset information is stored among the EEPROM38.Last judgement in this step can be carried out according to this memory.
When this program is not sponsored program, even and when judging that this program is a sponsored program also will be shown the time, this processing proceeds to step SP69.The transponder of reading at the step SP66 platform that number is set to front end 20 is selected control program then.As a result, the tuner 21 of front end 20 receives the carrier wave of the transponder that is provided with by CPU29 number.Therefore, when the button icon of the position that is moved at cursor with same carrier wave as button icon corresponding channel in data be transmitted (when this transponder of two is number identical), the conversion of carrier wave (frequency) is unwanted, thereby this processing is skipped.
To proceed to step SP70 locked according to the state in the register of front end 20 (not shown) to confirm this selection option program in this processing then.In other words, its confirms that the carrier wave of the transponder that is provided with at step SP69 number has been received.This processing advances to step SP71 with the ID of packets of information that the register 24aA will be merged in demultiplexer 24 is set (ID that is read out at step SP66) then.Thereby demultiplexer 24 extracts in the packets of information that is included in the transponder carrier wave that step SP69 is provided with, and at the selected programme information bag of step SP66, the transponder of front end 20 outputs number also temporarily is stored in it in the buffering area of Data Buffer Memory 35.
At step SP72, restriction inserts to detect and is carried out then.In other words, owing to sponsored program is encoded, so they are decoded.This processing is unwanted for sponsored program (uncoded program) not.Therefore this processing is skipped.
Then, this processing proceeds to step SP73 to carry out the predetermined set in the register 24a of demultiplexer 24, so that video data is provided for Video Decoder 25 and voice data is sent to mpeg audio decoder 26.
Then at step SP74, decoding begins to be set to the register of mpeg video decoder 25 and mpeg audio decoder 26.Thereby, in the pictorial data of the selected program of step SP66 with voice data is decoded and output from mpeg video decoder 25 and mpeg audio decoder 26.These data are employed and demonstration and output sound then.
Turn back to step SP61 in this processing, wait for next one input from remote-control command device 5.Under the situation that cursor is moved further, then repeat same processing.In addition, move under the situation about being transfused to, be suspended in that processing constantly, and the processing of moving in new cursor of response will begin immediately at new cursor when the processing from step SP66 to step SP74 is performed.
When step SP67 judgement did not need sponsored program to show, the output that this processing proceeds to step SP68 and blue background image was commanded to mpeg video decoder 25.
Therefore, when the processing of step SP74 is carried out, be shown as the background images of total indication shown in Figure 20 program image, and the voice signal of this image program is followed in output by cursor 212 appointments.Simultaneously, be under the situation of sponsored program at the program of cursor 212 appointments, when showing that when not needing to deposit, background images be full indigo plant, and output sound not.
When the program of cursor appointment was sponsored program, this program was not received in some cases.Therefore the situation below can be prevented from.That is, when required program is selected, this program only program by program icon and the situation of user's charges paid under just be received.
In this way, selector button switch 131 is directed and operates cursor being moved to a preposition, thereby is output and receives the operation beginning immediately for the order by this program of reception of cursor 212 appointments of front end 20.Therefore, selecting and operating this selector button switch 131 with before finally determining scheduled program, the reception of this program is handled and has been begun.Therefore, when selecting the selected and operation of push-button switch 131, the reception of this program is carried out.Even the operation of this program is not done, this program also can be shown on monitoring arrangement 4 in respect to a short time of comparing in that situation that just begins program receiving constantly.
When step SP62 judged that the selection operation of vertical operation is carried out, this processing proceeded to step SP63 and discharges with the demonstration that OSD is set in the register of mpeg video decoder 25.This has just discharged the demonstration of total indication window screen.
Further at step SP63, the release of exporting at the still image of step SP40 setting shown in Figure 21 also is set up.Thereby, the screen decoding after step SP74 begins to change, when the channel that receives after still image was removed, the channel image after the conversion was shown immediately.
In this way, in this embodiment, when total indication was shown, background images was fixed to a still image.Then, when cursor on total instruction screen is moved and predetermined program when selected, the screen of total indication is eliminated, and simultaneously, selected channel image is shown.Therefore, when the scheduled program on total instruction screen is selected, random on the rear projection screen and cannot see and can be prevented from.
In the above-described embodiments, in the demonstration of total indicator panel, the channel image that had been shown in the past is fixed to still image.It can the fixed background image be a still image also when cursor is moved in total indication.
The example that Figure 23 and 24 expressions are handled in such cases.Figure 23 represents corresponding to the processing of handling shown in Figure 21.Figure 24 represents corresponding to the processing of handling shown in Figure 22.
Total indicated number shown in Figure 23 is handled basic identical in the total indicated number processing shown in Figure 21.Therefore in Figure 23, the processing at step SP40 shown in Figure 21 is omitted.In other words, when total instruction screen was shown, this background images was not converted into a still image and is left a motion video.
Then, select to handle and to be explained at the program shown in Figure 24.This program is selected to handle basic identical in the selection of the program shown in Figure 22 processing.Therefore, in program shown in Figure 24 was handled, step SP91 was inserted between step SP67 and the step SP69.Inserting step SP92 between step SP74 and step 61.Processing at step SP63 is changed to handling at step SP93 then.Other processing among Figure 24 is same as the corresponding step among Figure 22.
That is to say that in this embodiment, selector button switch 131 is directed and operates, and cursor is moved at step SP65, so that in step SP66, is read out corresponding to the program data of the button icon that has been moved.
When step SP67 judges that the program demonstration is set up, even this program is a sponsored program, this processing also proceeds to step SP91 and goes to be provided with, become a still image so that output to the image of the register of mpeg video decoder 25, and audio frequency output becomes in the register of mpeg audio decoder 26 quiet.In other words, when cursor was moved to the button icon of other program, the program that is shown as the motion video before being moved at cursor is converted into a still image and voice signal is muted.
Then at step SP69 to step SP74, the program that mpeg video decoder 25 and mpeg audio decoder 26 carried out the button icon that is moved to corresponding to cursor receives to be handled and decoding processing.
When these processing were done, this processing proceeded to step SP92 to be released in still image setting and the quiet setting that step SP91 carries out then.Therefore, after being moved, cursor is transformed into the motion video of a program corresponding to the button icon before cursor is moved and the still image that shown as still image.Then, after this, this processing turns back to the output that step SP61 removes to wait for the remote-control command device 5 of making a fresh start.
When step SP62 judged that selector button switch 131 is operated, this processing proceeded to step SP93, the release that shows with the OSD that is provided with for mpeg video decoder 25.This has just eliminated the total instruction screen that has been shown.This program motion video corresponding to the button icon that has shown after this screen conversion is shown then.
As mentioned above, in this embodiment, when cursor was moved to a new icon, the image shown in background was a still image by giving, so that the program of the button icon that moves on to corresponding to cursor receives to handle begun immediately.When this reception processing was carried out, this still image was transformed to the motion video of program that cursor moves to then.Therefore, compare with the embodiment of front, the user can discern the program that has been converted definitely.
Therefore, before the processing of step SP66 and step SP92 is carried out, after cursor has been moved to a new icon, be that moving cursor to a new icon is exported when operation at step SP65, these processing are interrupted.The processing of the program (channel) of the icon that has been moved to corresponding to cursor is performed then.
Further, in IRD2 shown in Figure 4, handle when program (channel) conversion is by the upper and lower push-button switch 133 of operating and remote controlling instruction device 5 channels or when digital button switch 138 is operating as input channel number, be performed at the still image of change-over time.
In other words, the channel shown in Figure 25 flow process (program) conversion process by be operating as move up and down channel channel up and down push-button switch 133 remove input instruction, or remove directly to import predetermined channel number by operand word push-button switch 138 and be performed.
At step SP111, the processing that the program image that changes current reception becomes a still image and static sound is performed.In other words, in mpeg video decoder 25 and mpeg audio decoder 26 registers, each processing is set up.Therefore, if channel switch is transfused to, the image that then has been shown has become a still image and voice signal by static.
Then, this processing proceeds to the reception processing that step SP112 removes to begin to be received in conversion program (channel) afterwards.In other words, CPU29 control response begins the needs of the demultiplexer 24 that the reception of new channel (conversion after channel) handles corresponding to new input channel, removes to control front end 20.At step SP113, this handles wait, is done up to conversion process.Then, this processing proceeds to step SP114, is released in still image that step SP111 is provided with and quiet according to finishing of conversion process.In other words, at this moment, the channel motion video after the conversion is shown, and has sound to be output corresponding to motion video.
Therefore, in channel switch, the unordered and visual invisible state of image is prevented from.
Figure 26 represents another remote-control command device 5 example of structure.In this example, replace the selector switch that can operate in eight directions 131 shown in Figure 5, arrow button 201 to 204 works in bottom left and right, and the push-button switch 200 that can carry out selection operation is provided.Further, in this embodiment, wired push-button switch 145, TV push-button switch 146 and DSS push-button switch 147 have the interior lighting pattern.LED148 to 150 shown in Fig. 5 is omitted.The LED (not shown) that is arranged in push-button switch 145 to 147 back is configured, so that they are according to its operation and luminous.
Although the arrangement of other push-button switch and position are different, they are substantially the same in situation shown in Figure 5.
In the above-described embodiments, cursor is with predetermined brightness, and color or flicker are shown.Also may show this cursor with an arrow or with the irrelevant mark of button icon.This point is the cursor that is used from the pointer effect of specifying a precalculated position.
Further, in the above-described embodiment, program is selected in total pointing-type.The present invention can be used for selecting in other pattern the situation of program.
Further, the present invention is used in fact to be explained with the situation of the IRD2 of monitor 5 (television set) cooperation with respect to this invention.
