Fig. 2 is that its formation of optical recording media record/play-back device comprises as lower device: the tuner 10 of tv tuner programme signal; Demodulation digital data stream in tuning signal, for example transport stream (transport stream) of transmits data packets (transport packet) formation, and the digital demodulating apparatus 11 in survey data packet header; After top transmits data packets sequence (sequence) is made of error correcting code ECC (Error Correction Code) form, be modulated to the record DSP device 12 of the signal that is used to write down; According to the signal of input, approval is to the drive unit 13 of the drive current of light picker 2 records; Read with DVD+/-light picker 2 of the signal that the signal of the similar optical recording media 1 of R or record send from drive unit 13; Export binary system (binarized) play signal in the signal that reads from above, be used for the RF device 20 of the electronic signal of wrong (FE) signal of focusing and trail-and-error (TE); With binary play signal recovery is the broadcast DSP device 21 of numerical data; In the numerical data of restoring, transport stream is separated (demuxing), separated the demodulation multiplexer (demuxer) 22 that extracts management information and navigation (navigation) information in the numerical data of the audio-visual data of output encoder or said recovery in the above; The audio-visual data of face code and output audio video signal A/V decoder 23 in the decoding; Generate the OSD device 33 of writings and image signal; The synthesizer 24 of synthetic outputting video signal and above-mentioned writings and image signal; According to focusing rub-out signal and trail-and-error signal, control light picker 2 and its incident beam (being used for record and broadcast), and drive the Servocontrol device 31 of the spindle motor that rotates optical recording media 1; Storage memory of data 32; Follow the tracks of the clock apparatus 34 on date and time now; And the input of handling the user, and the control device of controlling recording/play operation on the whole, promptly microcomputer 30.
Below, implement the together in addition detailed explanation of operation of the record/play-back device of method that example is Fig. 3 and Fig. 2 for one of program recording title determining method.
In the record/play-back device of Fig. 2, under the state of operating power approval, if the channel program signal of tuning present setting in the tuner 10, demodulate transmitted data flow in the tuning signal from digital demodulating apparatus 11, in the transmitting data stream of demodulation, separate specific packet ID, for example have ' transmits data packets of 00 ' numerical value (hereinafter referred to as ' TP '), and the data of carrying in the packet are sent to microcomputer 30.These data are the information of expectation program present cannel broadcast or that will play, for example program title, reproduction time, the segment (fragment) of the simple declaration of other program etc.
S10, thus, above said microcomputer 30 after the data that concentrate to transmit, conform to its form and to be resolved, constitute the timetable of the broadcast program of present tuning in to channels, and be stored in the memory 32.Simultaneously, if according to user's request converted channel, carry out identical operations for this channel, the broadcast program timetable of the channel of conversion also constitutes in addition.According to identical therewith method, store the timetable (ST is a program start time in the table, and ET is a program end time) of the broadcast program identical in the above in the said memory 32 with Fig. 4.Necessity that the timetable identical with the above all do not obtained for all channels is the tuning specific channel of pre-recording, and the broadcast program timetable of only obtaining this channel gets final product.
S11, on the other hand, the input medium of user by being equipped with in the record/play-back device is for example with the similar input unit of remote controller (Remote controller), import the reproduction time section of self wanting the channel recorded and program to estimate, set pre-recording.This input can be finished easily by the program of (embeded) GUI (Graphic User Interface) of configuration in the microcomputer 30, and the picture that is used for importing is made of the writings and image picture that OSD device 33 generates according to the control of microcomputer 30.The reception of remote signal normally receives the means (not shown) by ultraviolet ray and finishes, and this resolves by microcomputer 30.
If the pre-recording that the user set to wish, before the time arrives, above said record/play-back device be in holding state.In holding state, except that acknowledging time and the necessary inscape of affirmation user's mains switch requested operation, do not provide electrical power for operation.
Whether the present date of following the trail of in the clock apparatus 34 above S12, said here microcomputer 30 monitor in holding state is the time started of pre-recording time period of having set.Before time started or 1-2 divide, approve the electrical power for operation of all inscapes, be converted to running status, the top said tuner 10 of control simultaneously, the channel of tuning pre-recording.Before pre-recording began, the reason of tuning in to channels was the playing programs information that is used to obtain corresponding channel with top described identical.Simultaneously, control Servocontrol device 31 makes the CD 1 of installation be rotated by suitable record multiple.
S13, the program of playing in tuning channel is demodulated into transmits data packets according to digital demodulating apparatus 11, from this packet of program start time according to record DSP device 12 by after being used for ECC form that mistake corrects and constituting, be modulated to record and use signal, begin to carry out record along magnetic track in the CD 1 that rotates by drive unit 13 and light picker 2.This recording operation was finished till the concluding time of the pre-recording time period of setting.
S14 judges and records the concluding time.
S15, the time of confirming from clock apparatus 34 is if the deadline of recording, above said microcomputer 30 finish present recording operation, carry out the operation of title between the decision recording areas.For this reason, above in said microcomputer 30 each channel program timetable in being stored in memory 32 retrieval record the program log of channel, search and comprise recording starting time and concluding time one program at least, simultaneously in the program of searching, at recording starting time and a specific program of long reproduction time in the concluding time, read the title of this program, decide and record interval title.
The example of lifting Fig. 5 a is illustrated, the recording time of pre-recording for afternoon 8:40 divide branch to 9:45.In this time period, comprise at least three programs (Program A, B, the part of C, program A comprise the time be 8:40 divide divide to 8:50 till meter 10 minutes, program B comprise the time be from 8:50 divide divide to 9:38 till, counted 48 fens.In addition program C comprise the time for till dividing from 9:38 to 9:45, counted 7 fens.Thus, comprise in the time of recording that the longest program of time is B, so divided the interval (500) of recording, the title of program B for 8:40 to the 9:45 branch according to the present invention, read in the program log that ＂ talk show ＂ stores in memory 32, and give the title of this interval (500).
Another is implemented in the example, is not the time span to comprise in the recording time, but decides the title of recording the interval with the ratio of record data size.
If said here microcomputer 30 begins to record, the timetable of retrieval corresponding channel program, in the time of recording setting, detect the broadcast program variation point, and stored, afterwards, to each separation or record before the end point, distinguish detection record in the size of data of CD 1, and stored.Record end simultaneously, according to each interval data volume, interval title is recorded in decision.For instance, under Fig. 5 a situation, 8:40 plays the size of data (DS1) of ending record to 8:50,8:50 has divided the size of data (DS2) of 9:38 member record, and 9:38 divided detect respectively to the size of data (DS3) of 9:45 member record after, whole data volume, the interval program title that promptly has the size of data that shared ratio is the highest among the DS1+DS2+DS3 are set at records interval title.
S16, for the interval of recording according to method recited above, if give title, above said microcomputer 30 one of information identical with Fig. 5 b (example of Fig. 5 a) formation that recording time and channel, title and recording location is relevant record clauses and subclauses (entry), and be recorded to the management information areas of CD 1.Information about recording location can be the number that index (indexing) has unit (Cell) information of recording interval positional information, also can be to record the interval filename that distributes or record interval physics to begin and the end address, outside this, also can be the multiple information of knowing altogether of interval position on the CD of announcement.
On the other hand, when the pre-recording interval comprised the situation of two programs at least, the program length of time latter half accounted for whole recording time, for example account for more than 40%, with the decision of the title of latter half of program for recording interval title.If below 50%, decision for the reason of latter half of program title is, usually the actual play of broadcast program is than more late broadcast of time period of estimating, under the situation of this playout-delay, it is more close to record the included time period of two programs of interval time period, for instance, during the situation identical with Fig. 6, the ratio of recording the whole recording time of interval 600 program map B is about 46.2% (=30/65).Implement the suggested ratio of example as the present invention one and surpass 40%, so the decision of the title of program B is recorded as and records clauses and subclauses for recording the title in interval 600.But record interval interior two program situations, the very low words of time ratio of latter half program, account for whole 40% for instance when following, decision provides to the user for the title of first half program, for the program part that pre-recording did not require in the time period, promptly 60% being recorded of announcement with top.
Identical therewith record and the title decision is finished at least once abovely generates and records tabulation, and this records tabulation is when user's program recording is confirmed request, reads from CD 1.The frequency signal that reads with light picker 2 from top said CD 1 is converted to numerical data by RF device 20 and broadcast DSP device 21, at this moment, the data of management and navigation information (comprising the top said tabulation of recording) go to microcomputer 30, and the A/V data flow is sent to the demodulation multiplexer (demuxer) 22 of rear end.
From play DSP device 21, transmit record list information and be stored to memory 32 temporarily after, conforming to constitute also with the output picture provides to OSD device 33, thus, can select one in the tabulation that the user exports and record clauses and subclauses on picture.At this moment, the user can see that recording interval title also easily finds self desired recorded program in tabulation.
What picture showed records in the tabulation, record clauses and subclauses if in tabulation, select one, above said microcomputer 30 record interval positional information with reference to its selector bar purpose, control Servocontrol device 24, light picker 2 is moved to corresponding position, finish read operation.That reads records interval censored data stream according to top described, is sent to demodulation multiplexer (demuxer) 22, and demodulation multiplexer (demuxer) 22 extracts the A/V data of coding in the data flow of input, and approval in A/V decoder 23, exports with the A/V signal like this.The user can watch recorded program thus.
According to the present invention described above, also be applicable to the simulated programmer signal of nonnumeric signal, usually simulated programmer signal transmits the mode of programme information, for example during the NTSC mode, the modulation of the horizontal-drive signal of the ad-hoc location in the vertical synchronizing signal, carry for example pieces of information of 2 bytes (fragment).Same as shown in Figure 7, constitute record/play-back device, for simulated programmer signal, the method for Fig. 3 described above is applicable to for example identical with Fig. 6 with Fig. 5 a situation, interval title is recorded in decision, and it is shown to the user by recording tabulation.
The formation of the record/play-back device of Fig. 7 different with the device of Fig. 2 comprises synchronizing signal demodulator 61, PES encoder 62 and PES decoder 63.Here said synchronizing signal demodulator 61 detects the 2-byte data of modulating in the particular sync signal, offer microcomputer 30 '.Here after said PES encoder 62 is converted to numeral with the picture signal of importing, for example be encoded to the MPEG mode, coded data is converted to the stream that packet header is arranged (the PES:Packetized Elementary Stream) packet of Voice ﹠ Video, after separating (muxing), record DSP12 approval.And play the reverse action of the PES decoder 63 execution PES encoders 62 in the end, isolate Voice ﹠ Video PES packet in the separation of input (muxing) the PES sequence of data packet, therefrom the A/V signal is exported in decoding respectively.
On the other hand, above said microcomputer 30 ' concentrate the pieces of information of 2 bytes of above-mentioned input, form with certain format, forms the program log identical, in addition reference when the title in interval is recorded in decision with Fig. 4.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
