Description is specifically seen Fig. 1, shows the device with the timer pre-programmed message 10 of the video/playback machine of coding according to the present invention.Main element comprises remote controller 12, has the cassette tape video/enlarger 14 of G code decoder, and remote controller 12 is by command signal 16 control video/enlargers.Remote controller 12 can have a plurality of keys, comprises numerical key 20, G code switch 22, function key 24, programming key 26 and power key 27.Various devices are arranged in the remote controller 12, and 12 pairs of keys of remote controller make an explanation and by infrarede emitting diode 28 appropriate command signal 16 are sent to VCR when key is pressed.Except the G code switch 22 on Fig. 1 remote controller 12, remote controller 12 is basic identical with other remote controller on function.Configuration G code switch 22 only is to allow the user when using the G sign indicating number remote controller 12 is locked in the G pattern to carry out the timer pre-programmed, and the G sign indicating number then is the name of getting for the compressed code of coding CDTL information.

The G sign indicating number is made of 1 to 7 bit digital, although also available more multidigit, it is associated with a specific program.The user can search the G sign indicating number in program guide, and as long as input G sign indicating number can replace prior art requirement user and imports actual channel, date, time and length (CDTL) order on remote controller 12.

In order to understand the advantage of using the G sign indicating number, illustrate that the preferred plan of prior art present circumstances, " programming on the screen " of using Direct Digital to import are helpful.This technology will be with about 18 keystrokes, and the user has to its sight line is switched between TV screen and remote controller back and forth when input CDTL information.This situation is similar to the user dials one 18 when consulting telephone directory telephone number.Turning to back and forth of bond number that relates to and sight might produce mistake.The typical keystroke order that uses the last CDTL programming carrying out of screen timer to record is as follows:

First programmings of PROG 21 15 07 30 2 08 00 2 04 PROG (PROG) key 26 enters programming mode.Push a succession of numerical key 20 then.2 are meant that timed recording rather than time are provided with.1 is meant that the user imports the setting of program 1 now.The 15th, the date.The 07th, initial hour.The 30th, initial minute.2 refer to afternoon (PM).Next sequence 08 002 is the termination time.The 04th, channel.At last, hit the PROG key once more to withdraw from programming mode.

On the contrary, originally can be: PROG 1138 PROG with typical G sign indicating number sequence to this order " coding " and import as follows.For distinguishing this order is that G code switch 22 should forward " ON " position to through the G sign indicating number of coding.Can use independent keys " G " place of switches.G sign indicating number programming keystroke order then is: G 1138 PROG.

Use G sign indicating number is not got rid of " on the screen " of having imported programme information and is confirmed.When the situation that is in " ON " position when the G code switch was imported keystroke " PROG 1138 PROG ", this G sign indicating number was decoded and show following information by television set:

Time started on program date dwell time channel

1138 15 7：30PM 8：00PM 4

For the G sign indicating number can be used, must to decoding and the configuration device that is used for this purpose.With reference to figure 1, disposed the cassette tape video/enlarger 14 that has the G code decoder, use to cooperate remote controller 12.The command signal of being sent by remote controller 12 16 is 32 sensings of photodiode, and is transformed to the signal of telecommunication by command signal receiver 30.This signal of telecommunication is sent to instruction control unit 36, and the latter makes an explanation to order and judges and how this order responded.As shown in Figure 1, instruction control unit 36 also might receive the order from hand controller 34, and this hand controller generally is contained in the VCR machine.If instruction control unit 36 judgements have received the G sign indicating number then this G sign indicating number have been delivered to G code decoder 38 decipher.G code decoder 38 is a CDTL information with the G code conversion, and this information is used for setting-up time/channel programmer 40 by instruction control unit 36.Clock 42 is contained in VCR inside.It is located in the VCR usually and is used for record date and time.Clock 42 mainly be for time/functional block of channel programmer 40 and G code decoder 38 is used.Time/functional block of channel programmer 40 is by instruction control unit 36 CDTL information setting.When clock 42 is read correct date and time, then time/functional block of channel programmer 40 connects record/playback function piece 44 and carries out record.Simultaneously, tuner 46 be tuned to the correct channel of TV signal 18.User's may command record/playback function piece 44 is that manner of playback is to watch program by televimonitor 48 subsequently.

The other method of control video tape recorder is to make instruction control unit 36 keep whole CDTL information and no longer with this information time of sending to/channel programmer 40.Instruction control unit is also by regularly reading 42 writing times of clock.Then instruction control unit with the order time of being sent to/channel programmer 40 to turn on and off video tape recorder, send a command to tuner 46 make it according to CDTL information orthochronous be tuned to correct channel.

Clock 42 also is an input of G code decoder 38, and this just allows the G sign indicating number to be decoded as the function of clock, and this provides a kind of safety measure to this decoding technique, and makes it more to be difficult to duplicate.Certainly, this requires coding techniques also to be necessary for the function of clock.

Fig. 2 illustrates a kind of possible realization of instruction control unit 36 and G code decoder 38.Instruction control unit 36 functional block available microprocessors 50, random access memory 52 and read-only memory 54 realize that described read-only memory is as the program storage.I/O functional block 56 is suitable for receiving order from order signal receiver 30, hand controller 34 and clock 42, and signal is outputed to display 35, clock 42 and time/channel programmer 40 functional blocks.If microprocessor 50 translates the G sign indicating number and is received, then the G sign indicating number is sent to microcontroller 60 and decipher.Microcontroller 60 has the read-only memory 64 of a random access memory that embeds 62 and embedding to be used for program and form storage.Clock 42 can be read by microprocessor 50 and microcontroller 60.

Another selection that allows microcontroller 60 carry out the decoding of G sign indicating number is directly will to be inserted in read-only memory 54 program stored in the decoding of G sign indicating number.This just can exempt the needs to microcontroller 60.Certainly also can use other hardware of carrying out the decoding of G sign indicating number.With the selection of any enforcement mainly is economically selection.

Square frame among Fig. 1 and Fig. 2 is that choosing has technology known, and appears in the following patent: Fields, the patent No. 4,481,412; Scholz, the patent No. 4,519,003; And the Brugliera patent No. 4,631,601.For example, clock 42 is similar to element 7 in the Scholz patent and the element 17 in the Brugliera patent.Other like is: command signal receiver 30 is similar to element 14 in the Scholz patent and the element 12 in the Brugliera patent; Tuner 46 is similar to 10 of element 6 in the Scholz patent and Brugliera patent; Time/channel programmer 40 is similar to element 8,11 in the Scholz patent and the element 16 in the Brugliera patent; Recording and reproducing function piece 44 is similar to the element 1,2,4 in the Scholz patent; Instruction control unit 36 is similar to element 11,10 in the Scholz patent and the element 12 in the Brugliera patent; Microprocessor 50 is similar to the element 27 in the Fields patent; RAM62 is similar to the element 34 in the Fields patent; ROM54 is similar to the element 33 in the Fields patent; Hand controller 34 is similar to the element 15,16 in the Scholz patent; And remote controller 12 is similar to element 26 in the Scholz patent and the element 18 in the Brugliera patent.

Fig. 3 illustrates another most preferred embodiment of the present invention.Among Fig. 3, be equipped with the remote controller 80 that band embeds the G code decoder.The remote controller of the G code decoder 80 that band embeds is very similar to remote controller 12 except having increased the G code decoder.Notice also display 84 might be set in any remote controller.The remote controller that has the G code decoder 80 of embedding can cooperate common cassette tape video/enlarger 70 to use, and at this moment the G code decoder of embedding need not be arranged in the video/enlarger.The label of the sub-element of cassette tape video/enlarger 70 is the same with the above-mentioned cassette tape video/enlarger 14 that has a G code decoder, and has identical functions, does not just have G code decoder 38.The advantage of this most preferred embodiment is to cooperate at present the VCR use of usefulness.These VCR do not have G sign indicating number decoding function.Replace their original remote controller with remote controller and can improve timer pre-programmed ability greatly with appropriate cost with inherent this G sign indicating number decoding ability.

A kind of possible structure of the G code decoder 82 of packing in the remote controller 80 of Fig. 4 explanation with embedded G code decoder.Microprocessor 60 can be as before to the decoding of G sign indicating number, and as with the interface of display 84, clock 85, keypad 88 and light-emitting diode 28.Available in addition other hardware tools is carried out the decoding of G sign indicating number.In remote controller 80, be provided with clock 85, make G code decoder 82 that clock 85 one of is imported as it.This makes the decoding of G sign indicating number is a function of clock 85, and provides safety measure to this decoding technique, makes it more difficult and duplicates.

Aforesaid remote controller with embedded G code decoder sends channel, date, time and length information to cassette tape video/enlarger 70, and this video/enlarger uses the tuning correct channel of CDTL information, starting and termination recording function.Since each plate or model to every kind such as the channel key, begin to record and stop the information that recording key sends different infrared pulses is arranged, so remote controller has nothing in common with each other to variant cassette tape recording/enlarger.Every kind of used specific infrared pulse of key type can be described as the vocabulary of specific remote controller.Every kind of model also can have different agreement or the order of finishing such as the required button of timer preprogrammed functions.Button agreement or the order of realizing certain function can be described as sentence structure.As all constructing a unique remote controller, in the remote controller of then correct vocabulary and sentence structure directly can being packed into for every kind of model.

It is by carry out the interface problem of more multioperation with simplification and existing cassette tape video/enlarger with the remote controller of embedded G code decoder to another selection of cassette tape video/enlarger 70 that the remote controller that has an embedded G code decoder sends channel, date, time and length information.Particularly, if remote controller is not only carried out the decoding of G sign indicating number to CDTL, and by 85 writing times of clock, just remote controller might only send channel, begin to record and cease and desist order to cassette tape video/enlarger so.Channel, initial sum stop one or two normally basic key order, this means not relate to complicated agreement or sentence structure.Like this, the communication of different model cassette tape video/enlarger only needs that memory is arranged in remote controller, and for example the ROM64 among Fig. 4 is used to store the agreement of whole models or at least quite big subclass.The G sign indicating number can be decoded as channel, date, time and length information with the G sign indicating number as importing in the past on remote controller, these information storages are in remote controller.By the 85 recoverable times of clock, and when arriving orthochronous, remote controller can send to order the VCR assembly automatically to be tuned to correct channel and starting and termination record.Estimation only needs 2 bytes to be stored to about 15 each keys of key, as the vocabulary of various cassette tape video/enlarger models.Like this, cover 50 kinds of models, remote controller also only needs 30 * 50=1500 byte memory.Be necessary that relative VCR assembly suitably places remote controller, make the infrared signal of sending by remote controller to be received by the VCR assembly.

Another most preferred embodiment provides a kind of universal remote control 90 that has embedded G code decoder.Universal remote control provides the ability of many kinds of different remote of imitation.This has reduced the number of the remote controller that the user must have.This can by on the universal remote control study function key 94 be used for finish, as shown in Figure 5.If learning functionality key 94 is pressed with another key, just these parts enter mode of learning.Detect in addition filtering and be discernible bit pattern before recording battery backed static RAM (SRAM) as the specific IR pulse mode of particular key with waveform shaping by microcontroller by infrared photodiode 96 from infrared (IR) pulse that remains to be learnt of remote controller input.Can carry out aforesaid operations to all independent keys.

The example of more complicated study is as described below.As learning functionality key 94 being pressed with programming key 26 when " ON " at the G code switch, this component identification goes out and prepares the key sequence of the instantiation of being scheduled to of the timer pre-programmed of specific VCR record in addition.User's enter key sequence then, universal remote control 90 therefrom derive and the agreement of recording timing device pre-programmed sequence.Because different VCR can have different timer pre-programmed command formats, it is necessary therefore doing like this.

As pressing other key not by learning functionality key 94 time, microcontroller can be known and now is in execution pattern.As this key of pressing is in the direct command key one, and then microcontroller is read the pulse train of being stored and sent command word, output light emitting diode 28 is supplied with in pulse by output parallel I/O functional block from its static RAM (SRAM).Be " OFF " if this key is PROG (programming) key and G code switch, can to identify the descendant key before next PROG key be timer pre-programmed CDTL order to microcontroller so, and by light-emitting diode 28 this order is sent.If being set to " ON ", presses G code switch 22 programming key 26, just then the descendant key that identified before next PROG key of microcontroller is the order of timer pre-programmed G sign indicating number.It is decoded as channel, date, zero-time and length (CDTL) with the G sign indicating number, microcontroller is checked the relevant infrared pulse pattern in its static RAM (SRAM) " dictionary " and is connect together before giving light-emitting diode 28 pulse sending by output parallel I/O functional block then, so that send complete information to VCR with a Continuous Flow form.

A kind of possible structure of the G code decoder 92 that Fig. 4 explanation can be packed in the universal remote control 90 with embedded G code decoder.Microcontroller 60 can be used for as before to G sign indicating number decoding and the interface that is used for and comprises the I/O functional block of photodiode 96.In addition, also available other hardware tools carries out the decoding of G sign indicating number.

Universal remote control also can be simplified the interface problem with existing cassette tape video/enlarger in another way.Particularly, if universal remote control not only is decoded into CDTL to the G sign indicating number, and by 85 writing times of clock among Fig. 4, universal remote control just might only send channel, opening entry and the finish command to cassette tape video/enlarger so, as previously mentioned, the singly-bound order that these orders are normally basic this means not relate to complicated agreement or sentence structure.Communicate by letter with the cassette tape video/enlarger of complete different model like this and only need each key of universal remote control " study " remote controller that it substituted.The G sign indicating number can be imported on universal remote control as preceding, and is interpreted as channel, date, time and length information, and these information stores are in this universal remote control.By 85 correction times of time, and correct constantly the time when arriving, universal remote control can send a command to the VCR assembly automatically, be tuned to correct channel and beginning and end record.Be necessary correctly to place universal remote control so that the signal that universal remote control is sent can be received by the VCR assembly with respect to the VCR assembly.

There are many methods to realize the decoding of G sign indicating number.It is evident that most with a big look-up table.The G sign indicating number is as index.Unfortunately, this can make efficient very low, and forms very expensive decoder owing to contain memory.The total storage capacity of using is the function of total number of combinations.Considering that as us 128 channels, 1 month 31 days, zero-time at a certain hour and half hour in 24 hours 1 day then have 48, is that increment has 16 kinds of length to select with the half an hour, and so total number of combinations is 128 * 31 * 48 * 16=3,047,424.This number of combinations can be represented with 7 decimal numbers.The address of this form should be 7 decimal numbers.Than under the rough sledding, this needs the look-up table of about 4,000,000 row * 15-16 sum, and this depends on certain protocol.These sums are corresponding to " programming on the screen " required CDTL information.Each numeral is represented with 4 bits.Like this, the required total storage bit number of this look-up table is about 4,000,000 * 16 * 4=256,000,000.Prior art is about 1,000,000 of every chip at present.Use the G sign indicating number of direct look-up table to decipher the number of chips that needs selling at exorbitant prices like this.

Fortunately, the method that also has much clever execution G sign indicating number decoding.Fig. 6 is a kind of flow chart of G sign indicating number decoding technique of the best.For understanding the decoding of G sign indicating number, being easy to the most is earlier to Fig. 7 flowchart text G sign indicating number coding techniques.The inverse process of G sign indicating number coding is described then, G sign indicating number decoding technique.

G sign indicating number coding can be finished on any computer, and finishes before the program guide of preparing any G of comprising sign indicating number.To being imprinted on each program on the guide, at step 142 inputting channel, date, time and length (CDTL) code 144.Step 146 is read channel, date, time and the length in the priority vector storage 122 respectively, and they are stored in the read-only memory 64.Priority vector storage 122 comprises 4 tables: priority vector C table 124, priority vector D table 126, priority vector T table 128 and priority vector L table 130.

Ordering makes the most normal channel of seeing that little priority number be arranged to the channel priority list.An example of data is as follows in the priority vector C table 124:

Channel 472356 11 13

Priority 01234567

There is equal priority on all dates in a middle of the month in general, and like this, the low number of days in a middle of the month and low priority number be corresponding as following example in priority vector D table.

Date 123456789 10

Priority 0123456789

Arrange the priority of time started like this, make the main time that low priority number be arranged and the late into the night program high priority number is arranged.For example, priority vector T table comprises:

Time 6:30pm 7:00pm 8:00pm 7:30pm

Priority 0123

An example of data is as follows in the priority vector L table 130:

Program length (hour) 0.5 1.0 2.0 1.5 3.0

Priority 01234

Suppose that channel date time span (CDTL) 144 data are 5 10 19.00 1.5, mean channel 5, this moon the 10th day, 7:00pm and 1.5 hours length, so to above example, Cp, Dp, Tp, Lp data 148, promptly the priority lookup result of Fig. 7 medium priority table 124,126,128 and 130 mid bands, date, time and length is 4913.Step 150 is a binary number with Cp, Dp, Tp, Lp data conversion.The number of bits of each conversion is determined by the number of combinations that comprises.7 of Cp can be expressed as C7 C6 C6 C4 C3 C2 C1, can be used for 128 channels.5 of Dp can be designated as D5 D4 D3 D2 D1, can be used for 1 month 31 days.6 of Tp can be designated as T6 T5 T4 T3 T2 T1, can be used for 48 kinds of time starteds once per half an hour of 24 hours 1 day.Length is with 4, can be designated as 8 hours the program length of reaching most that L4 L3 L2 L1 can be used for step-length half an hour.Wherein total 7+5+6+4=22 position information is corresponding to 2 ²²=4,194,304 kinds of combinations.

Next step is to use a hierarchical key sign indicating number (bit hierarchy key) 120, and it is stored in the read-only memory 64 to write down these 22.Position hierarchical key sign indicating number 120 can be this any ordering of 22.For example, position hierarchical key sign indicating number can be:

L8?C3……T2 C2 T1 C1 L1 D5 D4 D3 D2 D1

22?21……10 9 8 7 6 5 4 3 2 1

A best such ordering position hierarchical key sign indicating number, the program that makes most probable become timer pre-programmed theme has the binary number of low numerical value, thereby can omit the keystroke of the pop program of timer pre-programmed.Because all date and time informations have equal priority, D5 D4 D3 D2 D1 at first so.Then with T1 C1 L1, because which channel and length if having time no matter, owing to the ordering that the priority vector stores 122 medium priority vectors, T1 C1 L1 is most probable under every kind of situation on date.The next bit of hierarchical key sign indicating number is determined by the different probabilities of various combinations.Must understand in this pending calculating the probability of all channels, time and length.

For example, the channel probability can be:

Channel 472356 11 13

Priority 01234567

Probability (%) 5 4.3 43 2.9 2.1 2 1.8

Time probability is:

Time 6:30pm 7:00pm 8:00pm 7:30pm

Priority 0123

Probability (%) 8 7.8 65

And the length probability is:

Program length (hour) 0.5 1.0 2.0 1.5 3.0

Priority 01234

Probability (%) 50 20 15 54

As above illustrated with the probability that each channel, time and length interrelate, can be used for determining suitable ordering.Because the priority vector table is sorted by the most normal channel, time and the length seen, it is known that the order of preference between the various binary digits in the table is for example selected at C7 C6 C5 C4 C3 C2C1 interdigit.The C1 position is at first selected, because it is selected between the most preceding two inputs from the channel priority list as the lowest-order binary digit.Select the C2 position then, or the like.Similarly, available T1 and L1 before what its time in office and the length position.At first should use the combination of C1, T1, L1 and D5 D4D3 D2 D1 position, make all these information can be used for channel, date, time and length.So, and need to total data position specified data, even the some of them position is a binary zero because data bit all has identical priority can all use D5 D4 D3 D2 D1 position.

At this moment, position hierarchical key sign indicating number should be:

First channel binary digit of T1 C1 L1 D5 D4 D3 D2 D1 C1 self can only select between 2=2 channel, and the most preceding two channels have 5% and 4.3% probability respectively.The difference probability (differentia1probability) of C1 is 9.3% like this.Equally, the difference probability of T1 is 8+7.8=15.8, and the difference probability of L1 is 50+20=70.If strictly observe a hierarchical key sign indicating number ordering rule, then preceding 8 orderings of position hierarchical key sign indicating number are:

C1 T1 L1 D5 D4 D3 D2 D1 is because L1 has the highest difference priority, so it should be the next highest significant position behind the D5, after meet T1 (as next highest significant position), be C1 (as next highest significant position) then.Attention position hierarchical key sign indicating number is inserted the highest difference probability position then from least significant bit D1.This is for to often seeing that program constitutes the purpose of tight code.

Is problem in this link of cataloged procedure what is next highest significant position in the hierarchical key sign indicating number, T2, C2 or L2? this is still by difference probability decision, can be calculated according to last table per 1.Owing to be that binary digit is handled, with the C2 of C1 combination can be 2 ²Select in=4 channels to Duo 2 channels than C1 is single.So the difference probability of C2 is the additional probability of these two extra channels, for example this probability is 4+3=7.In a similar manner, can be with the C3 of C1, C2 combination 2 ³Select between=8 channels, make up than C1 and C2 and many 4=2 ^3-1Individual channel.The difference probability of C3 is the additional probability of these four extra channels like this, to this probability of this example is: 2.9+2.1+1.8=8.8.Use same quadrat method, the difference probability of T2 and L2 can be calculated as 6+5=11 and 15+5=20 respectively.In case calculate all difference probabilities, next step is to determine which bit combination more can be several.

To above example, which combination more can be several: T2 and C1, L1, or C2 and T1, L1, or L2 and T1, C1.This will determine the next bit in this key.That is bigger, 11 * 9.3 * 70=7161,7 * 15.8 * 70=7742; Or 20 * 15.8 * 9.3=2938.8? 7 * 15.8 * 70=7742 that is combined as that has maximum likelihood in this case is corresponding to the combination of C2 and T1 L1.Therefore C2 is elected to be a next bit of hierarchical key sign indicating number.

With selecting next bit with quadrat method.Below which the combination more can be several: C3 and T1 L1, perhaps T2 and C1 or C2 and L1, perhaps L2 and C1 or C2 and T1.To example illustrated, which probability maximum: 8.8 * 15.8 * 70=9732.8; 11 * (9.3+7) * 70=12551; Or 20 * (9.3+7) * 15.8=5150.8? in this case, maximum likelihood be combined as 11 * (9.3+7) * 70=12551, corresponding to T2 and C1 or C2 and L1.Therefore, T2 elects a next bit of hierarchical key key as.All difference probabilities are repeated this process until finding whole keys.

In addition, position hierarchical key sign indicating number can only be some any bit sequence.The priority vector is relative to each other, for example makes length priority vector depend on not on the same group channel.Another kind of technology is to make position hierarchical key sign indicating number 120 and priority vector table 122 become the function of clock 42, as shown in Figure 7.This makes key and respective coding technology be difficult to duplicate or copy.

For example, might be the function of clock with the data-bit encoding (scramble) in the position hierarchical key sign indicating number 120.The function that the precedence preface is changed into clock does not influence the validity of position hierarchical key sign indicating number when minimizing is the most normal sees the program number of bits, because all data bit have equal priority.This can be with regularly for example every day or jede Woche switching D1 be the same with D5 simple.Like this, position hierarchical key sign indicating number 120 can

C1 T1 L1 D5 D4 D3 D2 D1 and

Change between C1 T1 C1 D1 D4 D3 D2 D5.Obviously, position hierarchical key sign indicating number also is possible as other arrangement of clock function.

Priority vector table also codified (scramble) is the function of clock.For example, preceding two channels are only exchanged periodically in the priority channel table.As by this technology, so among Fig. 7 in 148 Cp can change into the function of clock 42.For example,

Channel 472356 11 13

Priority 01234567 can periodically change into:

Channel 742356 11 13

Priority 01234567

This is quite wonderful safe practice.Just just lost efficacy because decoder is preceding two channels, otherwise be correct in the time spent.Other clock correlation also may provide fail safe for coding techniques.

Yet this can derive, and determines and bank bit hierarchical key sign indicating number 120.In step 154, step-by-step hierarchical key sign indicating number 120 is reset binary digit Cp, Dp, Tp, Lp, to produce one 22 binary number.22 bits that to derive in the step 56 that binary number is transformed to decimal system G sign indicating number are transformed to decimal number then.This result is a G sign indicating number 158.

If priority vector and position layering key can fine couplings to general masses' the custom of watching, can expect that so the G sign indicating number of the program more often seen can be more than 3 or 4 decimal numbers.

Since coding techniques has been described, decoding technique only is the inverse process of coding techniques so.This can finish according to the flow chart of Fig. 6.This preferred G sign indicating number decoding technique can be used on the G code decoder 38 of VCR14 or the inside of Fig. 3 and Fig. 5 remote control G code decoder 82 and 92.

First step 102 is input G sign indicating numbers 104, then G sign indicating number 104 is transformed to 22 binary number in step 106.Write down these positions in step 108 according to position hierarchical key sign indicating number 120 then, with the position 110 of having been write down.In step 112 divided into groups together and be transformed to decimal number in these positions then.At this moment, obtain Cp, Dp, Tp, Lp data 114, these data are the index of priority vector table.To above example, vector 4913 is arranged in this step.Use this Cp, Dp, Tp, Lp data 114 in step 116 then, to search channel, date, time and the length in the priority vector storage 122.The CDTL 118 of last example is 5 10 19.00 1.5, means channel 5, the 10th day this moon, 7:00pm and 1.5 little durations.

As coding techniques is clock function, and then making decoding technique also is that the function of clock is absolutely necessary.Making a hierarchical key sign indicating number 120 and priority vector table 122 is possible for the function of clock 42, as shown in Figure 6.This makes key once more and then makes coding techniques be difficult to be replicated or copy.It also is possible making decoding and coding techniques depend on any other predetermined or pre-programmable algorithms.

Entirely so above G sign indicating number coding and decoding technique are preferred embodiments, but should be appreciated that, also have many by way of realizing that the present invention reduces the intention of the required stroke of timer pre-programmed.For realizing this purpose, there are a lot of methods to carry out G sign indicating number coding and decoding.Except only making coding and being decoded as the function of clock, also have many methods to make coding and decoding technique safer.This fail safe can be the result of any predetermined or pre-programmed algorithm.

In G sign indicating number coding and decoding technique, might produce for binary number with the mixing truth of a matter.For example, suppose and have only 35 channels that this needs 6 binary digits to represent, yet, because 2 ⁶=64,6 binary digits can be represented 64 channels.This result has 29 unnecessary positions in the binary numeration system.This just produces and may make the result of concrete G sign indicating number than the length of actual needs.Mix truth of a matter system and can avoid above-mentioned phenomenon.For example, under 35 channel situations, have 7 ¹With 5 ⁰The mixing truth of a matter system of the factor can represent 35 kinds of combinations and not have any free codes space.7 ¹It is 0,1,2,3,4 that the factor allows number.5 ⁰The permission number of the factor is 0,1,2,3,4,5 and 6.For example, decimal number 0 can be expressed as 00 in this mixing truth of a matter system.Decimal number 34 can be expressed as 46 in this mixing truth of a matter system, because of 4 * 7 ¹+ 6 * 5 ⁰=34.The major advantage of mixing truth of a matter system is the hierarchical key sign indicating number is sorted by priority.If preceding 5 channels have roughly the same priority, back 30 also roughly the same, mix truth of a matter system so and allow these two layers accurately to be represented.This is not to mix necessarily optimum of truth of a matter system.Binary number is easier expression in computer, uses the fixedly truth of a matter system such as binary number to allow the pyramid prioritization to be easy to be represented with the hierarchical key sign indicating number.

The another feature that all requires in all embodiments is a kind of like this ability, and promptly once the G sign indicating number of keying in program, the result just has every day or used weekly CDTL information.Generally, CDTL information was abandoned it once using just.In every day or write down weekly under the situation of same program, storage also uses CDTL information until being cancelled.Every day or the hope of repeated program can be by on the remote controller weekly, or be contained in the VCR hand controller " WEEKLY " (weekly) or " DAILY " (every day) button carry out.Another kind method is to use a key, and PROG key for example is within a certain period of time by repeatedly for example by being defined as every day twice, being defined as weekly by three times.For example, if the G code switch is 99 for the G sign indicating number of " ON " program that requires, can select per diem recording of this program by following keystroke so.

" PROG 99 DAILY PROG " or

" PROG 99 PROG PROG " G sign indicating number 99 variable CDTL information that are changed to are stored and use every day at this code of this situation.At fixed date opening entry and after this continue to use same channel, time and length information every day.So slightly change be since most of every day program different with Saturday, Sunday during Zhou Wei, understand will write down termination every day automatically.

In case set up every day or program weekly, then can unrestrictedly use.As require to cancel program, and if " CANCEL " (cancellation) button is arranged on remote controller or VCR hand controller, a kind of approach (no matter being common CDTL, every day or input weekly) of cancelling a program so is to key in following content:

" PROG XX CANCEL ", wherein XX is the G sign indicating number.Also the same with the front, finishing this function has other approach.

If " programming on the screen " is that effectively the selected program of timer pre-programmed can be checked on screen so.Every day or program weekly have its type indication.The G sign indicating number can show with corresponding C DTL information in addition.This just makes checks current " programme " and adds very easy than Polymera or cancellation program.

Illustrate according to television calendar of the present invention at Fig. 8.As shown in the figure, television calendar has a plurality of days parts 202 in certain year, a plurality of days parts 204, a plurality of Time of Day parts 206, and channel identifier 208, descriptive program identifier 210 comprises programm name, presses TV guide publication same way as and arranges.It is relative with each channel identifier that what arrange is G sign indicating number or the compressed code indication 212 that comprises channel, date, time and the length information imported in the television calendar.It is very easy that Fig. 8 illustrates the programming of execution timer.It is all required that what do is to find out the program that will see and import compressed code and indicate shown compressed code.This is with must to handle the input of whole channels, date, time and length respectively opposite.At least channel, date and time have clearly record in TV guide.Usually as long as search the time that day part 204 begins new program, carry out the length that this program is obtained in some arithmetical operations then, just can obtain length by searching guide.Use compression G sign indicating number to exempt all these complex operations.

To cable television program, other needs explanation is arranged to G sign indicating number Useful Information.In the common TV guide, CDTL information all is ready-made to all the common broadcast channels with the number form formula that comprises channel number, for example channel 4 or 7.Yet,, in most of list of television programmes, only list channel name to cable channel such as HBO, ESPN etc.The reason of doing like this is at some metropolitan areas, for example Los Angeles (Los Angeles), TV Guide has only 1 edition, and quite a lot of wire radio is arranged, and wherein each can distribute to EBO or ESPN different cable channels number.For making compressed code can be used for the cable channel that extensive area TV Guide publication is announced, can use following method such as the G sign indicating number.

At first, permanently distribute unique channel for whole cable channels, this channel is effective in China.For example, we can give HSPN cable channel 1, and HBO gives cable channel 2, and SHO gives cable channel 3 etc.This distribution can be published by the TV guide publication.

Cassette tape video device, for example remote controller, VCR assembly or both, configurable two kinds of additional mode: " settings " (set) with " cable channel " (cable channel).A kind of mode that the user interface of these patterns is provided is two additional buttons of configuration: one is setting (set) button, and another is the cable channel button.These two buttons are located in the video Cassette recorder equipped assembly or on the remote controller, shown in Fig. 1,3 and 5, wherein " setting " button is an element 168, and " cable channel " button is an element 170.Certainly, other user interface also is feasible.

Secondly; The TV viewer must carry out once " setting " process of its VCR to all cable channels that he wants to see.Each cable channel distribution number is associated with the channel of local wire radio.For example; Suppose local wire radio with channel 6 as ESPN; Then cable channel number 1 can be given ESPN, cable channel number local wire radio channel number ESPN 16 HBO 2 24 SHO 3 23 " " " " " " " " that and is as shown in the table. cable channel title is distributed " DIS 8 25 users can carry out " setting " process by the following button of pressing like that on its remote controller:

SET?06?CABLE?CMANNEL?1?PROGRAM

SET?24?CABLE?CMANNEL?2?PROGRAM

SET?23?CABLE?CMANNEL?3?PROGRAM

SET?25?CABLE?CMANNEL?8?PROGRAM

Should " setting " (setting) process can produce a cable channel address table 162, this table is packed among the RAM52 in the instruction control unit 36.To above example, cable channel address table 162 will have following information.

Cable channel address table 162

1 6

2 24

3 23

″

″

″

8 25

After carrying out " settings " process, the TV beholder can select the cable channel that will see with out-of-date methods, for example, presses the ammonium button 24 selection HBO of keypad.Also available new method is selected, and for example presses " cable channel 2 " (CABLE CHANNEL 2) and also can select HBO.The advantage of new method is that TV guide can deliver (C2) behind program specific, as long as the beholder checks that it is local cable channel 24 that the channel identifier of appointment replaces remembering HBO like this.When pressing " cable channel " (CABLE CHANNEL) button, instruction control unit 36 just know the local cable channel checked in the cable channel address table 162 number with VCR be tuned to this correct channel.

To the timer pre-programmed and use compression G sign indicating number, the method for distinguishing broadcasting and cable channel is increase the 8th channel bits, this position to the common broadcast channel be made as 0 and to cable channel for example HBO be made as 1.The 8th channel bits can be one of low price of for example the 3rd C3 in 8 channel bits, makes to be used for limiting and often sees the figure place minimum of channel (no matter being common broadcast or cable channel).To the common broadcast channel, according to priority vector C table 124 is deciphered other 7.To cable channel, 7 other positions can be deciphered by cable channel priority vector table 160 independently, and this vector table can be stored among the ROM54 of microcontroller 36.This cable channel priority vector table can be in advance for the whole nation or be that the zone that specific big zone television guide publication is covered sets at least.

Publication has the TV guide of the compressed code that is called the G sign indicating number to print off following cable channel information:

6：30PM〔C2〕HBOXXXXXXXXXXXXXXXXXXXXXXX(4679)

XXXXXXXXX (program specific) XXXXXXX

(C2) before the XXXXXXXXXXXXXXXXXXXXXXXXXXXHBO reminds the beholder only need press CABLE CHANNEL 2 (cable channel 2) and selects HBO.(4679) be the G sign indicating number indication of this specific program.

Fig. 8 illustrates the part of TV Guide.All cable channels have the cable channel numbers 188 of appointment after the cable channel memonic symbol.In addition, the same with the broadcasting channel that has with the compression G sign indicating number 212 of this channel association, arrange wired channel information.

To the timer pre-programmed, the beholder only needs the G sign indicating number input process input digit 4679 according to parts, for example PROG 4679 PROG.G sign indicating number decoding unit is decoded as this G sign indicating number " cable channel 2 " and cable channel signal 164 is sent to instruction control unit 36, as depicted in figs. 1 and 2, because this G code of differentiation is that the extra channel bits of cable channel is " 1 ", in " setting " process, early form getting in touch of " cable channel 2 " and channel 24 so, therefore, when instruction control unit is received the cable channel signal, just can in cable channel address table 162, find out 2 and convert it to cable channel 24 immediately, and with it as at the appropriate time record channel.By the cable channel of G sign indicating number and appointment number is interrelated, rather than number interrelate with local cable channel, envoy's purpose G sign indicating number can be that effectively can there be many different wire radios in this zone to whole local zone, and each has different local cable channel number.

In order to comprise cable channel compression G code feature, decoding and encryption algorithm are respectively as Fig. 9 and shown in Figure 10.Explanation is earlier encoded before explanation decoding.The main variation of Figure 10 and Fig. 7 is to add cable channel priority vector table 160, and is searching when wired channel is encoded and using this vector table 160 in the step 180 of priority.In addition, just be encoded, Cp Dp Tp Lp be transformed to position, position in the binary number step 182 that the adding of cable channel position is suitable so as a cable channel.This position can be as previously discussed the position C3.Can as preceding, determine position hierarchical key sign indicating number so that compress the most normal figure place of seeing program, yet these 23 of needs are long to hold this cable channel position.Maximum compression G code length still is 7 (decimal systems), because 2 ²³=8,388,608.

Decoding just in time is the inverse process of cataloged procedure as shown in Figure 9.After step 108, add the testing procedure 174 of cable channel position is also tested to take a decision as to whether " 1 " this cable channel position effectively.If " 1 " then signals to instruction control unit 36 by the cable channel signal 164 among Fig. 1 and Fig. 2, will be used for cable channel by the CDTL 118 that G code decoder 38 sends to it.Then, instruction control unit number is searched local wire radio channel according to the cable channel of appointment.In the step 176 of Fig. 9, comprise that the priority vector table of cable channel priority vector table 160 is used to search CDTL 118 information.

The replacement practice that instruction control unit receives cable channel signal 164 is that the G code decoder is carried out and comprised from specifying the cable channel number whole decode procedures to the conversion of local wire radio number.The situation that this has just become Fig. 3 remote controller to realize.If comprise this step, Figure 11 illustrates the realization of whole decoding algorithms.Remain to be increased whole are the steps 166 that specified channel are transformed into local wire radio channel, if cable channel is pointed out to relate in the cable channel position, then step 166 is carried out searching of cable channel address table 162.Step 166 has substituted step 174 among Fig. 9 effectively.

It should be noted that another problem be can pre-programmed number of programs.Because the G sign indicating number has been simplified the process of input program greatly, might user very fast association and will import large-scale program, however some existing VCR can only store and reach 4 programs, and some can store 8.The user is easy to fall through because of the programming restriction of VCR like this.

To a kind of solution route of this problem, be to carry out the decoding of compression G sign indicating number and in remote controller, be equipped with enough memories to store in a large number for example 20 or 40 programs with remote controller.Remote controller has the ability that periodically once several programs stored is sent to the VCR main frame.For this ability is provided, in remote controller, need to be called the extra memory of stack memory 76, as shown in figure 12, in addition, identical with Fig. 4.The available random access memory is realized stack memory 76, and in fact stack memory 76 is stationed in microcontroller, as RAM62.

Stack memory 76 can be carried out the place of new input, insertion and the deletion of timer pre-programmed message.It also can be the place of editing.The top memory cell of this stack, for example preceding 4 unit are just in time corresponding to available timer preprogrammed memory in the VCR main frame.Whenever the stack memory top changes, then fresh information is sent to the VCR main frame and refresh.

Figure 13 illustrates the event sequence when the user imports G sign indicating number program on remote control keypad.For describing, suppose that the VCR main frame can only handle 4 programs.Suppose that the stack memory space is 20 timer pre-programmed programs.With reference to the flow chart among Figure 13, when the user at step 230 input G sign indicating number, microcontroller 60 is decoded as CDTL information with this G sign indicating number earlier in step 234, then this information and " importing " adjunct word (entered) is presented on the display.Program after step 236 microcontroller then will be deciphered is input to stack memory.

If the top line of input places the top unit of stack memory with it.If existing several programs in the stack memory, then the program that will newly import temporarily places the stack memory bottom earlier.In step 240 stack memory ordering is correct time sequencing, makes on the time program the earliest appear at top unit, bottom last program is placed on the time on.The time that the is noted that essence that goes up the stack memory of ordering is as changing stack memory unit n, then changes all unit below it.

For example, suppose that stack memory has 6 times to go up ordering input, then its time ordering of Shu Ru new input places unit 3 (1 is top unit).Be placed on unit 3 as this input, then 3,4,5,6 information will move to unit 4,5,6 and 7 in the unit originally.Unit 1 and 2 remains unchanged.

Microcontroller 60, after according to time sequence, whether n input changes with in the past before step 242 check, and wherein n equals 4 concerning this example.In this case, because new program has been imported unit 3,3 content moved to unit 4 now in the unit in the past.Because the programme of 4 inputs of VCR main frame should just in time corresponding stack memory unit 1 to 4, so input 3 and 4 must be revised in the VCR main frame.Therefore microcontroller will newly be imported 3 and 4 steps 244 at Figure 13 and send to main frame.Behind time-sequencing, be input to unit 5 if newly import program, import 1 to 4 with before remain unchanged, and microcontroller do not send any message to the VCR main frame yet, this microcontroller continues as step 246 pair clock 85 and keyboard 88 are monitored.Suppose that remote controller points to the VCR main frame as user during at step 230 input G sign indicating number.Other step of Figure 13 takes place very fast, so that when remote controller still points to the VCR main frame, just in step 244 variation is sent.

At program of step 232 decision deletion, then earlier carry out this deletion as the user at stack memory.If influence preceding 4 inputs, then microcontroller will be revised back information and send to the VCR main frame.Uninfluenced as preceding 4 inputs, then remote controller does not still send any content.The deletion only change stack than lower part (unit 5 to 20).Can carve in due course this fresh information is sent to the VCR main frame.

Meanwhile, the VCR main frame is carried out its timer programing function, is finished its regularly pre-programmed input one by one.In case finished whole 4 video inputs, the stack in the remote controller sends some new inputs and removes " being full of " VCR main frame (if this stack has input more than 4).

The real-time clock 85 of remote controller is monitored the time that uses up with program in definite main frame by microcontroller.With reference to Figure 14 flow chart, microcontroller step 250 fixed time testing clock and with the programme of VCR main frame on time of identical stack top portion program (such as, preceding 4 inputs).If do a fixed time testing, judge that recording of main frame programme finish, so as when in step 252 test is popped a plurality of input being arranged, then display is made as the flicker pattern or shows that in step 258 flicker information prompting user sends more Polymera.The user picks up remote controller next time, and this flicker can be reminded him the programme of VCR main frame is finished, and this program input with the remote controller storage has been full of the VCR main frame.The user can only pick up remote controller and point to the VCR main frame and press " ENTER " (input) key.This " jumps out stack memory top content " in step 260, promptly is to make stack up jump out whole inputs of 4 unit.Then, microcontroller in step 262 promptly with new " stack top ", 4 inputs in top send to the VCR main frame.It is empty until whole stack to repeat this process.

Using record another most preferred embodiment of device of pre-programmed of compressed code is the instant programmable device 300 of Figure 15.This instant programmable device 300 has numerical key 302, CANCEL (cancellation) key 304, REVIEW (inspection) key 306, WEEKLY (week) key 308, ONCE (once) key 310 and DAILY (M-F) (day) key 312 of numeral of marking 0 to 9, is used for instant programmable device 300 programmings.A lid covers other key that is used to be provided with instant programmable device 300 usually.When mentioning when covering 314, expose following key: SAVE (preservation) key 316, ENTER (input) key 318, CLOCK (clock) key 320, CH (channel) key 322, ADD TIME (adding the time) key 324, VCR key 326, CABLE (wired) key 328, TEST (test) key 330.The further feature of the instant programmable device shown in Figure 15 is LCD 350 and red warning light-emitting diode 332, and the front elevation view of the instant programmable device 300 of Figure 16 illustrates front infrared (IR) diode 340 that is installed on positive 338.Instant programmable device 300 placed treats that set device is for example video Cassette recorder equipped 370, cable box 372, and the front of television set 374, as shown in figure 19, front infrared ray (IR) diode 340 can signal performance recording is controlled.IR transparency cover 336 covers the extra IR emitting diode that will be described hereinafter.

Figure 18 illustrates the details of LCD 350.Can on display, see definite text 354 at different time, and input area 356 is arranged.Show time bar 352 in the display bottom, time bar function illustrates hereinafter.

The annex of instant programmable device 300 is mount pads 360, as shown in figure 17, be used for instant programmable device 300 is fixedly arranged between left side facade 362 and the right side facade 364, instant programmable device 300 can slide between left side facade 362 and right side facade 364 until front alignment flanges 365, this flange is positioned at mount pad 360 fronts and cross-over connection left side facade 362 and right side facade 364, shown in Figure 17 A.Element 362,364 and 365 1 is used from and makes instant programmable device 300 placed in the middle so that when using this instant programmable device as shown in figure 20, make IR transparency cover 336 and IR diode 342,344,346 and 348 as shown in figure 17 suitably alignment in order to launching infrared ray.Mount pad 360 has an alignment flange 366, and the purpose of this flange is to make mount pad back edge alignment, along back edge, and limits the border of placing alignment flanges 366 along the front of cable box or VCR or similar device, as shown in figure 20.When aliging as shown in figure 20, mount pad 360 with 300 alignment of instant programmable device so that left IR diode 342, IR diode 344, two back IR diodes 346 and right IR diode 348 can send signal to video Cassette recorder equipped 370 and cable box 372 as shown in figure 17 in case of necessity down.Be positioned at television set 374 self inside as VCR and/or cable box functional block, then instant programmable device 300 can be placed and transmit a signal to television set 374, no matter is the mode with Figure 19, or in Figure 20 mode mount pad is placed the television set top.

By using mount pad 360, the user once aligns mount pad 360, instant programmable device with locking equipment to be programmed, remember to place the tram to pass through 340 emissions of front infrared (IR) diode instant programmable device 300 and need not the user, as shown in figure 19, use the existing experience of various remote controllers to show that it also is difficult on the coffee table for example that the most optimistic estimation of do places the fixed position with remote controller.Thereby mount pad 360 programmable device 300 when coming positioning instant with controlled device has solved this problem.Place left IR diode 342, down IR diode 344, two back IR two utmost points 346 and right IR diode 348 are launched left, downwards, backward and to the right.Reflector is got a definite form downwards, and mount pad 360 is placed on component top to be programmed.A left side and right emission allow parts to be programmed in the left side or the right side.The back IR diode 346 that configuration is launched backward is so that signal reflects from wall or indoor other object.Positive IR diode 340, left IR diode 342, right IR diode 348 and following IR diode 344 are to realize with 25 degree angle of departure diodes.Dispose two back IR diodes with so that this oriented energy is bigger, these two diodes are with 5 degree angle of departure diodes realizations, are used for focused energy and provide from the reflection of wall or the more IR energy of indoor object.

Most of VCR and cable box can be controlled by Infrared remote controller, yet different VCR and cable box have different IR codes.Though the VCR and the cable box of hundreds of different model are arranged on the literal, fortunately have only tens of kinds of IR code collections.Each set has " speech " of tens required different keys of expression, for example " power supply ", " recording ", " channel increases ", " channel down ", " stopping ", " 0 ", " 1 ", " 2 " etc.Record for control VCR and cable box, only need following " speech ": " 0 ", " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " power supply ", " record, " stopping ".All set are used for the memory of the IR code storage of these speech at instant programmable device 300, are arranged in the microcomputer 380 of Figure 21 and 22.When instant programmable device 300 was set, user-interactive ground inputed to instant programmable device 300 with the kind and the model of its VCR and cable box.In the working control process, can access the correct set of IR code from memory.Have only the user under the situation of a VCR, the infrared code that can access this specific VCR is controlled VCR.Have the user under the situation of a VCR and a cable box, from set, access IR code " power supply ", " recording ", " stopping ", and from set, access the IR code of " 0 " to " 9 " corresponding to cable box corresponding to VCR.Reason is in this case, and cable box control channel switches.Therefore, channel switching signal " 0 " must be delivered to cable box rather than VCR to " 9 ".

At first, the user carries out sequence is set.At first, the user searches model corresponding to VCR to be programmed, plate several numbers in a table, and described tabular has gone out VCR trade (brand) name and 2 decimal number codes.Then VCR is transferred to the channel 3 or the channel 4 of normal use, the user turn-offs this VCR.The user presses VCR key 326 then.When display illustrates VCR, the user presses 2 decimal numeral codes (for example RCA is 01) of finding in VCR model/plate table.The user points to VCR with instant programmable device 300, presses ENTER (input) key 318 then.Red warning light-emitting diode 332 flickers, meanwhile it sends a test signal to VCR.Connect and become channel 09 as VCR, the user connects down SAVE (preservation) key 316 and proceeds to the clock step is set.If VCR access failure (" ON ") or on but do not become channel 09, the user presses ENTER key 318 once more, and red by the time warning light-emitting diode 332 stops till the flicker.When redness warning light-emitting diode 332 was glimmering, instant programmable device 300 sent next possible VCR code.Become channel 09 if VCR connects also, the user pushes SAVE key 316, otherwise the user again by ENTER key 318 until the VCR code that finds VCR work.If tried all possible VCR code of this trade mark, display just illustrates " END " (end).If so, the user presses VCR key 326 codes 00 and presses ENTER key 318 then, one at a time all trades mark is attempted all possible code.

In case find and store suitable VCR code, then next step is set is the clock that instant programmable device 300 is set.At first, the user presses CLOCK key 320.When display illustrates: when " YR: ", the user presses this year (for example 90), presses ENTER key 318 then.So display illustrates " MO: ", the user presses ENTER key 318 again by this moon (for example 07 is July)." DA: " date (for example the 1st day is 01), " Hr: " hour (for example 2 o'clock was 02), " Mn: " minute (for example 5 minutes is 05) and " AM/PM: " (am/pm) 1 are repeated above step for AM or 2 for PM.After this sequence, display illustrates " SAVE " several seconds, and display illustrates current time and the date of having imported then.The user no longer need be provided with clock on its VCR.

Then, if instant programmable device 300 also is used as the cable box controller, it is as follows that step is set so.At first, find the numeral corresponding to the model plate of cable box to be controlled (converter) in cable box type plate sublist, described tabular goes out cable box plate and corresponding two decimal codes.VCR is transferred to channel 03 and 04 turns off VCR then.Then cable box is transferred to normal channel 02 or 03, and is maintained connection (" ON ").Press CABLE key 328 then.When display illustrates " CAB-: ", 2 decimal number codes that user's input is found in cable box model trade mark table point to instant programmable device 300 cable boxes (converter) and press ENTER key 318.When redness warning light-emitting diode 332 was sending to cable box with test signal, this diode just glimmered.If cable box becomes channel 09:, the user presses SAVE key 316 so, yet, if cable box does not change to channel 09, then the user presses ENTER key 318 once more and waits by the time red warning light-emitting diode 332 stops flicker, sends next possible code simultaneously.Repeat this step and become channel 09, and at this moment the user presses SAVE key 316 until cable box.If display illustrates " END ", then the user had tried all possible cable box code of this plate.If so, the user presses cable code 00 and ENTERR key 318, so that attempt all possible plate code one at a time.

To some people (may because they cable or satellite be arranged), the channel of listing in TV guide or television calendar be different from the channel of their television set or cable.If different, the user does following processing.At first, the user presses CH key 322.Display has demonstration like this: " Guide CH TVCH ".The user pushes the channel (for example, channel 2 is by 02) that prints on TV guide or the television calendar then, and the user receives the channel that this prints out by this channel from its local CNN then.Then the user presses ENTER key 318.Each channel on the channel of channel that being different from of drawing up prints is repeated aforesaid operations.When this process of end, the user presses SAVE key 316.

Generally speaking, regional TV guide or television calendar have and for example point out to distribute to each wired and broadcasting channel: HBO, CNN, ABC, CBS, the chart of the channel of NBC etc.This chart can be corresponding to a left side two row of for example Figure 28.For example, suppose that TV guide or television calendar give HBO with channel 14, but user's CNN transmits the HBO programs at channel 18.Because the channel difference, the user need use CH key 322.The user by the CH key (showing that the flicker of two spaces is arranged under " Guide CH " ".The user is by 14 then.(show TV CH now " under two spaces flickers).So the user is by 18 and ENTER key 38.Each different channels is repeated this process.During end, the user presses SAVE key 316.

After having preserved channel and being provided with, the user can be by checking setting by CH key 322 and REVIEW key 306.By pushing the demonstration that 306, delegation of REVIEW key roll up each setting contents of channel on the ground repeatedly.

Then whether the position that can test to determine instant programmable device 300 of user is good.At first, the user confirms that VCR turn-offs and the insertion plug, and be sure of that cable box (if any one words) remains " connection " (ON).The user can be by TEST key 230 then.As have only a VCR, then become channel 09 when VCR " connection " and begin to record, then VCR " shutoff " (OFF), then the VCR controller places a good position.

As a cable box is arranged simultaneously, so, when VCR connected (" ON "), cable box was transferred to channel 09VCR opening entry, and VCR stops also " shutoff " then, and then instant programmable device 300 places a good place.

For operating instant programmable device 300, VCR should remain " shutoff ", and keeping cable box is " connection ".The user searches program recording desired compression sign indicating number in TV guide.In TV guide, list compressed code 212, as shown in Figure 8.TV guide/the calendar used for present embodiment has the element 188 and similar elements shown in Figure 8 in need not Fig. 8.The compressed code 212 of user-selected program is input to instant programmable device 300 by using numerical key 302, and the user selects the frequency of program recording then.The user records this program once by ONCE key 310 in the time of being ranked, perhaps the user records this program until cancellation by WEEKLY key 308 in the identical weekly time of being ranked, and perhaps the user records this program until being cancelled by DAILY (M-F) key 312 in the same time of being ranked of every day on Monday to Friday.Program of the serial that do not broadcast weekend is the most useful to for example broadcasting every day for this.For confirming this input, date, channel and the time started of the program of being imported by the user deciphered and show immediately by instant programmable device 300 to compressed code.The length of the program of importing is also by shown across the time bar 352 of display bottom.Each time bar the is represented 1 hour program of (or less than 1 hour).

Order can be launched so the user only need be placed on instant programmable device 300 near VCR and the cable box, and carves in due course, and instant programmable device 300 meetings " connection " are VCR (ON), changes into correct channel and program recording, then " shutoff " VCR.The user only needs really empty tape to be inserted.

REVIEW key 306 allows the user (to check that progressively (step through) imported program.With the time preface is that date and chronological order show these programs.Whenever press REVIEW key 306, then show next program, be shown entirely, and show " END " up to importing program.As pressing REVIEW key 306 once more, demonstration can turn back to current date and time.

Wish to cancel a program as the user, then the user until showing the program that will cancel, the user presses CANCEL key 304 then by REVIEW key 306.Display can show " CANCELLED " (cancellation).In addition, any moment user just allows the user to begin by next wrong number as long as press CANCEL key 304 again.

Some TV programme, for example live sports cast may skim on the time gap (timeslot) that is ranked.For guaranteeing to record down whole program, the user can be by ADD TIME key 324 to increase recording length, even this program is recorded.The user presses REVIEW key 306 and shows this program, presses ADD TIME key 324 then.Whenever press ADD TIME key 324 once, recording length adds 15 minutes.

When showing current time and date, below 24 hours required empty tape amounts also shown by time bar 352 across the display bottom.Each time bar the is represented 1 hour tape of (or less than 1 hour).The user tackles this and conducts a survey to guarantee that enough blank tapes are arranged before VCR is unattended.

Each input one program code, all inputs of instant programmable device 300 automatic gaugings are to guarantee not having time-interleaving between the program input.Want to import a time as the user and go up and the program of importing the program overlapping in the past, " CLASH " (conflict) information then occurs.Like this, conclude as step 432 among Figure 23, the user has following selection: the program of input before 1) wishing to keep and abandon new input as the user, and what the user need not do, and after postponing in short-term, display returns current time and date is shown; 2) if the user will be with the section directory that begins earlier to the remainder that finishes to record again second program, then the user is again by ONCE key 310, DAILY (M-F) key 312 or WEEKLY key 308 (no matter which can import this code by).Identical as two program zero-times, then record the program of input recently earlier.As notice that " GLASH ", user determine new program more important than the program of input in the past, the program of input re-entered new then before then the user can cancel.

In some place, for example in some part of Colorado, the time that some channel that wired system is play is listed than local TV guide is wanted Zao or slow 3 hours.This is owing to depend on whether this channel receives the time difference of east or western satellite broadcasting.To recording the user who lists slow 3 hours program of time than TV guide, this process is as follows.At first, the user imports this program code, presses SAVE key 316 (being+) then, presses ONCE key 310, DAILY (M-F) key 312 or WEEKLY key 308 on demand again.To recording Zao 3 hours program of the time of listing than TV Guide, this process is as follows.At first, the user imports program code, connects ENTER key 318 (using-) then, presses ONCE key 310 on demand again, DAILY (M-F) key 312, or press WEEKLY key 308.Instant programmable device 300 shows will record the time of program rather than the time shown in the TV guide.

Some display message make instant programmable device 300 more the user welcome.Show that " LOBATT " points out that battery need change." Err:ENTRY " points out the invalid input during being provided with." Err:COPE " points out that the program code number of importing is not effective numeral.As show that this information, user should check TV guide and re-enter this number." Err:DATE " point out the user to Saturday or Sunday program tried video selection every day (MONDAY to FRIDAY); To cross that program more than 7 days try to select weekly or every day video because 300 permissions of instant programmable device will be weekly or the selection of recording every day be used for the program (± 7 days) in current week; Or tried the program that finished of input.The memory that " FULL " expression waits to record the stack memory of program, the random-access memory (ram) of programmable device 300 inside is realized when instant is filled.So the user can cancel one or more programs before the new program of input.The program of record is prepared in " EMPTY " (sky) expression not input.What can be stored in instant programmable device 300 waits that recording number of programs becomes with available RAM density, can change to more a plurality of from 10.

Figure 21 is a schematic diagram of realizing instant programmable device 300 required circuit.This circuit is made up of microcomputer 380, oscillator 382, LCD 384, keypad 386,5 road IR reflectors 390 and red warning light-emitting diode 332.Microcomputer 380 is made of CPU, ROM, RAM, I/O port, timer, counter and clock.ROM is used for procedure stores, and one of purpose of RAM is the stack storage that is used to wait to record program.LCD 384 is displays 350 of Figure 15 and Figure 18.Keypad 386 is realized all keys previously discussed.5 road IR reflectors 390 are by front end infrared (IR) diode 340, left IR diode 342, IR diode 344, two back IR diodes 346 and right IR diode 348 are formed down.Figure 22 illustrates the detailed schematic diagram and the front components identical of instant programmable device 300 circuit and labels with same numeral.Microcomputer can be implemented with the NECuPD7530X parts, and it can directly be connected with display, keypad, light-emitting diode and oscillator.25 degree IR diodes are realized with the NEC313AC parts, and 5 degree IR diodes are realized with the Liton2871CIR diode.

In Figure 23,24,25, show respectively and be used to carry out program input, inspection and program cancellation in the read-only memory (ROM) that is stored in microcomputer 380 and carry out the program flow diagram of recording.Its process such as above-mentioned Figure 23 that is used for the program input are made up of following steps: the step 402 that shows current date, time and time bar in the inactive state of instant programmable device 300; The step 404 whether keyboard scan is imported with the decimal system compressed code of determining numeral; The step 406 that shows the code of input; The step 408 whether code of subscriber checking input is correct, and the user presses the step 428 of CANCEL key 304; The user shifts to an earlier date or postpones the step 410 of 3 hours time started by SAVE key 316 or ENTER key 318; The user presses the step 412 of ONCE key 310, WEEKLY key 308 or DAILY key 312; Microcomputer is decoded as compressed code the step 414 of CDTL; The step 416 whether test conflicts with the program of storage, if conflict is arranged, show the step 420 of " CLASH " information, the user presses the step 422 of ONCE key 310, WEEKLY key 308 or DAILY key 312, then, as the step 432 of the described adjusting conflict input of " CLASH " option is discussed; And the input step 424 of no longer preserving; Be provided with display to ONCE show date, channel, zero-time and (time bar) at interval, perhaps DAILY is shown DA, channel, zero-time and at interval; The step 418 that perhaps WEEKLY is shown each day channel, zero-time and interval in week; The user presses the step 426 that ADD TIME key 324 increases by 15 minutes video time; The step 430 of customer inspection display; With the step 434 of time sequencing input program in the stack, wherein, this stack is the part of microcontroller 380RAM; And calculate the step 436 of required tape length with the refresh time bar.

The aforesaid Figure 24 flow chart of its process that is used to check and cancels is made up of following steps: the step 402 that shows current date, time and time bar; The step 422 that REYIEW key 306 is pressed; Whether test stack is empty step 444; The step 446 that shows " EMPTY "; Turn back to the step 448 that current date and time shows; The step 450 that shows the stack top input; The user presses the step 452 of ADD TIME key 324 and the step 460 of refresh time bar; The user presses the step 454 of REVIEW key 306, with the make progress step 462 of an input of turnup of stack; The user presses the step 456 of CANCEL key 304, shows " CANCELLED " and cancels the step 464 of program; The step 458 that the user does nothing, the step 466 that waited for 30 seconds; Wherein 30 seconds time outs can be realized with timer in the microcomputer 380.

Automatic recording program process and the aforesaid Figure 25 flow chart that is used to record are made up of following steps: the step 472 that stack memory top program zero-time was compared with the current time; The step 474 whether test is more Zao 3 minutes than program zero-time; Start the step 476 that red warning LED 332 glimmered for 30 seconds; The step 478 of indicated channel, zero-time and flicker " START " information, whether test has arrived the step 480 of correct zero-time, power source ON (connection) signal is sent to the step 482 of VCR and demonstration " REC " (video) information; Whether the test cable case is the step 484 of the input of VCR; Sending the channel switching signal arrives the step 486 of VCR and sends the step 488 of channel switching signal to cable box; Send the step 490 of video signal to VCR; With dwell time and current time step 492 relatively, whether test has arrived the step 494 of dwell time, shows the step 496 of " END " information; Send the step 498 of stop signal to VCR; Send the step 500 of power supply OFF (shutoff) signal to VCR, and the step 502 that ejects program from stack.

Figure 26 is the method flow diagram that channel, date, time and length (CDTL) is encoded to decimal system compressed code 510.This process can " off line " be finished and can be realized on all-purpose computer, carries out this process and can obtain to be included in compressed code 212 in Fig. 8 program guide or the calendar.The 1st step of coding method is the step 512 of inputting channel, date, time and length (CDTL), is used to channel, date, zero-time and the length C DTL 514 of concrete program input program.Next step is the step 516 of searching the channel of appointment, replaces each channel 518 with the channel 522 of appointment.Usually be that for example to the Web broadcast channel, as channel 2, specified channel is identical; Yet, to cable channel, distribute a channel such as HBO, in cable channel allocation table 520, find this channel, this is identical with preceding two row in Figure 28 table basically.Then, in the priority vector table, search the step 524 of the priority of channel, date and time/length and do searching in index execution priority vector channel (C) table 526, priority vector date (D) table 528 and priority vector time/length (TL) table 530 with channel, date and time/length respectively, to produce vector Cp, Dp, TLp 532.Using time/length (TL) table of combination that priority is set, is to consider between the popularity degree of these combinations and program direct relation is arranged.For example, the short program of 6:30PM is more welcome than 2 hours program, because this may be a date for dinner.

The channel priority list is sorted so that the most frequently used channel has low priority number.An example of data is as follows in the priority vector C table 526.

Channel 472356 11 13

Priority 01234567

Generally speaking, there are equal priority or use on all dates of one month, and such one month is a few days ago corresponding in priority vector D table 528 with low numerical priority, as following example.

Date 123456789 10

Priority 0123456789

The priority of available arranged program zero-time and length, each combination to zero-time and program length distributes a priority, make the more common combination of zero-time and length that one low priority number be arranged, and not too common combination have high priority number.For example, part priority vector T/L table 530 can be as follows.

Priority TL table

Time span 6:30PM 7:00PM 7:30PM 8:00PM

(hour)

0.5 8 4 7 10

1.0 12 15 13 18

1.5 20 19 17 30

Suppose that channel, date, time and length (CDTL) 514 data are channel 5, February 10 nineteen ninety, the length of 7:00PM and 1.5 hours, Cp, the Cp, the TLp data 532 that go up example so are 49 19.Next step is the step 534 that Cp, Dp, TLp are transformed to binary number and are coupled to a binary number, produces data word ... TL2TL1 ... C2C1 ... D2D1 536.To the above example that provides, will ... TL2TL1 ... C2C1 ... D2D1 536 words are transformed to binary number can produce three binary numbers: ... 0010011 ... 0100 ... 01001.The number of bits that uses in each conversion is determined by related number of combinations.This becomes with performance, yet, a most preferred embodiment uses 8 to Cp, be designated as C8 C7 C6 C5 C4C3 C2C1,256 channels can be provided, to Dp with 5, be designated as D5 D4 D3 D2 D1,1 month 31 days can be provided, TLp is designated as TL14 with 14 ... TL3TL2TL1,5 minutes length increments that can provide 24 hours to be no more than 3 hours every 5 minutes zero-time and program length, the program length of 15 minutes length increments of 3 to 8 hours of program length.This needs about 288 * (36+20)=16,128 kinds of combinations, can be by 2 ¹⁴=16384 kinds of binary combination provide.Total total 8+15+14=27 position information TL14 ... TL2 TL1C8 ... C2C1D5 ... D2D1.Each number of above example with being bound up on the spot patch and with them, is derived 27 binary number: 000000000100110000010001001.

Next step is with the position hierarchical key sign indicating number 540 that can be stored in the read-only memory 64, carries out the step 538 that binary digit is reordered according to position hierarchical key sign indicating number.As previously mentioned, position hierarchical key sign indicating number 540 can be ... TL2TL1 ... C2C1 ... any ordering of the position of D2D1 536, usually the program of selecting key to make most probable become timer pre-programmed object has the compressed code 212 of low numerical value, and this can make keystroke minimum.The ordering of position hierarchical key sign indicating number can be determined by the difference probability of various bit combinations as previously discussed.But the details of position hierarchical key sign indicating number 540 is derived in 120 explanations of contraposition hierarchical key sign indicating number, can be used for a hierarchical key sign indicating number 540 with quadrat method.For example, position hierarchical key sign indicating number can be
