Embodiment
Hereinafter, according to the present invention, describe the preferred embodiment of the method and apparatus be used to obtain the video signal recording space with reference to the accompanying drawings in detail.
Fig. 2 shows the structure of an embodiment of the record/playback apparatus of optical record medium, has wherein realized according to a kind of method of obtaining the program recording space of the present invention.
The record/playback apparatus of optical record medium shown in Figure 2 comprises: tuner 10, tv tuner broadcast singal; Encoder 12, with the vision signal after tuning be converted to digital signal and with for example mpeg format encode this digital signal and will encode after data decomposition and be multiplexed into Voice ﹠ Video PES (the basic stream after the packing) grouping; Record DSP unit 13, with ECC (error correction code) block format dispose the PES packet sequence and will dispose after the PES packet sequence be demodulated to the signal that is used to write down; CD-ROM driver 14, with writing light beam drive current feed-in optical picking-up head 2, optical picking-up head 2 is from being applied to light beam on the optical record medium 1 such as read output signal the optical record mediums such as DVD+R/-R 1 or according to the signal from CD-ROM driver 14 according to input signal; RF unit 20, extraction is used for the signal of telecommunication of playback signal, focusing error (FE) signal and tracking error (TE) signal of binarization from the signal of being read; Playback DSP unit 21, reconstruct is separated from the data of reconstruct from the numerical data of the playback signal of binarization and with management data and navigation data; Decoder 22 among the dateout of playback DSP unit 21 is PES packet sequence after multiplexed Voice ﹠ Video PES is separated, and the Voice ﹠ Video PES packet decoding after will separating becomes each A/V signal; OSD unit 33 produces character and figure signal; Synthesizer 24 is synthesized together vision signal and character and figure signal; Servo control unit 31 is controlled the axle motor that optical picking-up head 2 and incident beam (being used for record and reproduction) and control are used for rotary optical recording medium 1 according to focus error signal and tracking error signal; Memory 32 has wherein write down such as data and the navigation information of reserving the entry tabulation; Clock unit 34 is used to follow the tracks of current date and time; And microcomputer 30, be used for process user and import also controlling recording/playback operation on the whole.
The user input apparatus (not shown) of installing by the record/playback apparatus that uses Fig. 2 as the user (for example, during the recording menu the input unit such as remote controller) selecting to reserve, microcomputer 30 control OSD unit 33, thereby configuration and demonstration reservation menu as shown in Figure 3.The reception of the signal of remote controller realizes that by known infrared receiving device (not shown) this receiving course is explained by microcomputer 30.When display menu, the user is provided with the channel of wanting to be used for booking situation, writing time (start and end time that comprises the date), logging mode (for example, among HQ, SP, LP, EP and the SLP a kind of) and logging mode by the button input on using a teleswitch.Herein, logging mode can be disposable, every day or weekly.
When the user was provided with above-mentioned scheduled item and select " finishing ", microcomputer 30 was registered to this scheduled item in the booking situation tabulation in the memory 32.By said process, the program of user expectation is registered in the booking situation tabulation in the memory 32 all.After as above being provided with booking situation, the user closes the operating power of record/playback apparatus usually, thereby makes this device be in wait state.In wait state, except the operation of review time required composed component and user's request, do not provide operating power to power supply " ON/OFF ".
Whether current date/time that the clock unit 34 in the microcomputer 30 monitoring wait states is followed the tracks of is fully early than recording start time (for example, microcomputer 30 checks whether it has shifted to an earlier date 30 minutes) of any one specified booking situation item.When to during 30 minutes before the time started, operating power just is added on all composed components, thereby makes these elements be in running status; Then, microcomputer 30 control servo control units 31 make disc 1 rotation of being installed to reach suitable playback speed.For description of the invention, the disc of being installed 1 is assumed that it is the disk media of form that continuous recording data segment is managed as single recorded program, for example, and the DVD+R disc.The type of the disk media of being installed is judged with known technology.
Microcomputer 30 moves to the navigation area of disc 1 by control servo control unit 31 with optical picking-up head 2, and reads the navigate file that is write down in this zone.The signal that is read by optical picking-up head 2 is converted to binary signal by RF unit 20, and reconstitutes navigation information by playback DSP unit 21, thereby offers microcomputer 30.Navigation information is stored in the memory 32 and in needs and is quoted by microcomputer 30; Each recording of programs zone and relevant white space that microcomputer 30 is write down in the current disc of installing by utilizing this navigation information just can calculate.Hereinafter, for understanding purpose of the present invention, the disk media 1 of being installed is assumed that to have the record data that distribute as shown in Figure 1.Therefore, microcomputer 30 is with the white space 101 that disperses in the disk media 1 of being installed
1, 101
2, 101
3Big or small rough estimate become 882 megabits, 772 megabits and 551 megabits.
Microcomputer 30 signs are used to specify the logging mode of the item of booking situation the earliest, and the usable record time of calculating associated single white space.If specified logging mode is as shown in Figure 1 EP (data bit-rate is per second 2.45 megabits) for example, then the usable record time of single white space became about 48,42 and 30 minutes.
Microcomputer 30 will be according to the recording of programs time (being exactly 50 minutes 301 in the example of Fig. 3) of booking situation item record and according to the most last white space 101 in position
3Usable record time of logging mode compare.When if white space as shown in Figure 4 can't hold for the predetermined program of time recording, then will according to usable record time (about 120 minutes) of the logging mode of whole white spaces (summation of the white space of dispersion) with compare S401 for the predetermined recording of programs time of time recording.If all the usable record time of white spaces is greater than being the predetermined recording of programs of time recording during the time, just carry out the operation S402 that creates continuous white space in outermost.
In order to produce continuous white space, microcomputer 30 reads and first white space 101
1The data of second program prg# 2 of adjacent record, and with this storage in memory 32.Then, microcomputer 30 is by writing down DSP unit 13 and CD-ROM driver unit 14 from first white space 101
1These data of an opening entry.Because the interim storage space volume of memory 32 is limited, can holds so much program data and write down the last position of reading so read memory 32; By servo control unit 31 position of the writing light beam of optical picking-up head 2 is moved to first white space 101
1, and the data record that begins storage temporarily from this position is to memory 32.After the data of all interim storages have write down, write down last record position, the playback light beam of optical picking-up head 2 moves to the last playback position of precedence record then, and the data of reading recorded programs subsequently, and writes down this data after the record position that is formerly write down.If second program prg# 2 of being write down carried out said process, then top line prg# 1 and second program prg# 2 become one and connect that another is continuous recording.Then, in the navigation information of being stored from memory 32, microcomputer 30 upgrades about the record position information of second program prg# 2 adapting to the position after moving, thereby moves the first time of having finished recorded programs.
Next, read the data of the 3rd recorded program prg# 3, and write down this data after the afterbody of second program prg# 2 after formerly moving, and in an identical manner, from the navigation information of memory 32, upgrade information about the record position of the 3rd program prg# 3 according to the position after moving.Therefore, the white space of all dispersions becomes and assembles to form single continuous white space (403 zones of Fig. 4) after the program recording zone.After the accumulation process of as above finishing white space, microcomputer 30 records navigation information after the renewal in the memory 32 in the navigate file of disc 1 at once; This situation that disc withdraws from occurred be intended to prevent to upgrade navigate file on the disk media after mobile program recording before, and this situation can cause causing the program by moving recording the playback fault to occur because of recorded physical location and navigation information differ.
If among the comparison phase S401 formerly, according to whole usable record time ratios of the logging mode in dispersed record zone is that time recording and predetermined recording of programs time are short, then at the fixed time can not executive logging or only carry out the white space 101 of position in the end
3The common recording operation S410 of middle executive logging.In another embodiment of the present invention, even when according to the whole usable record time ratios of the logging mode in dispersed record zone be time recording and predetermined recording of programs time in short-term, the also white space that assemble to disperse as described above, and can write down a part of broadcast program that the white space assembled can hold in the writing time of appointment.
When the operation of aforesaid gathering white space is finished, microcomputer 30 checks that whether the current tracking time of clock unit 34 is corresponding to being the predetermined recording of programs time started of time recording, if and it becomes this time started, then microcomputer 30 control tuners 10 are de-tuned is the predetermined channel of time recording.
Therefore, encoder 12 is with the encoding video signal of mpeg format to receiving the channel after tuning, and these vision signals are configured to the PES grouping.Then, this packet sequence is configured to the ECC block format so that carry out error correction by record DSP unit 13, and is demodulated to tracer signal, thereby carries out record along a physical track that begins of the single white space 403 of outermost that is obtained from disc 1.In other words, opening entry belongs to the broadcast program of booking situation item.During writing down, record data (being called VOBU) and rise time clauses and subclauses in the microcomputer 30 configuration navigation elements, each entry record the size of each navigation elements and the time span of demonstration.With scope from 0.4 to 1 second and the configuration that realizes carrying out by one of encoder 12 coding or a more than GOP (set of pictures) unit according to navigation elements.Because said process and the present invention do not have direct relation, so omit more detailed description.
In above-mentioned recording process, arrive record end during the time when the current time of clock unit 34, the generation of record and single time clauses and subclauses all stops, and creates the navigation information about recorded programs.The navigation information of creating in this stage comprises: about the unit information of videograph section; Quote the programme information (PGI) of this unit information; And program chain information (PGC), it can be managed the section that is write down as single title.When having created aforesaid information, the time items for information that whole information is created during record is recorded in the navigate file of the navigation posting field that belongs to disk media 1.Because existing navigation information just is written into memory 32 and has suffered when disk media 1 is packed at first, so by adding the loaded navigation information of creating according to above-mentioned record of navigation information updating, and all be recorded in the navigate file of disc 1 by the whole navigation informations that write down after DSP unit 13 will upgrade, and stop recording operation by entering the standby mode of checking user's input.
By above process, even when the white space that disperses can't hold the single broadcast recording of programs, if the summation of white space can be held the writing time of this broadcast program, then this broadcast program still can be used as a record integrally.
When the user asks powered-down in the time different with the writing time of booking situation item, for example, after setting predetermined recording, assemble white space step will according to usable record time of the logging mode that disperses white space with compare for the predetermined recording of programs time of time recording, and carry out the operation of assembling white space in view of the above, thereby enter standby mode.
In the above-described embodiments, will according to usable record time of the logging mode of white space with compare for the predetermined recording of programs time of time recording; On the other hand, in another embodiment of the present invention, to can determine whether to carry out the aggregation operator of white space then according to comparing for the estimated record size of data of the logging mode of predetermined recording of programs time of time recording and the size of white space.
Hereinafter, another embodiment that is used to obtain the recording occurring continuously space according to of the present invention has been described.
As shown in Figure 5, when the last white space 101 of disk media 1
3Size (in the example of Fig. 1, be white space two white spaces 101 before in the end less than the big or small summation of disperseing white space except that this last white space
1, 101
2Big or small sum) time, carry out present embodiment.As previously mentioned, in order to prevent during writing down, to end because of continuous white space causes record inadequately, tape deck (it carries out record in the disc of the form that continuous recording section is managed as single recorded program, such as DVD+R) is usually at last white space 101
3Middle opening entry, and not at inner white space (101
1Or 101
2) one of in the beginning videograph.Therefore, when the size of last white space hour, when the user asks to write down inner white space being put into last white space is very favourable to hold writing time as much as possible.Yet, so that prevent from hour also to carry out an operation of assembling white space when the size of inner white space, the present invention only when inner white space (in disperseing white space last white space) big or small sum carried out during greater than white space at last big or small.
(for example carry out initialization operation when add working power to device, such as regulating servo feature so that in operations such as enterprising line item of disk media or reproductions) check afterwards when the distribution of white space and condition S501 are met, carry out the operation of assembling white space.
When the user selects specific recorded program and this program of request deletion,, can carry out the operation of checking above-mentioned condition S501 and assembling white space in view of the above making by the change navigation information after the respective regions of this recorded program incorporates in the white space.In another embodiment of the present invention, as shown in Figure 6, when the program that deletion is write down, as substituting of condition S501, when the program of being deleted is positioned at inside (in other words, the program that is write down is away from last white space) and the size by the continuous space that produced of deletion (size of the program that the size of the program that is write down or comprise is write down and the continuous space of adjacent white space thereof) greater than last white space 101
3Big or small the time (S601), can carry out the operation of above-mentioned gathering white space.
In another embodiment of the present invention, as substituting of the condition S501 that carries out the operation of assembling white space, when the size (SS_Last) of last white space and the ratio of disperseing the big or small summation of white space except that this last white space (=during SS_Last/SS_Others) less than the ratio (ct) of appointment, can carry out the operation of above-mentioned gathering white space.For example, then big more than 50% the time if the ratio ct of appointment is set to 2 when become size than last white space of the size of the continuous white space that white space produced by making up all dispersions, carry out the operation of assembling white space.The appointment of aforementioned proportion can be provided with by the environment setting of record/playback apparatus by the user.
Hereinafter, another embodiment that is used to obtain the recording occurring continuously space according to of the present invention has been described.
As shown in Figure 7, in the present invention, when deletion during specific program this specific program be not the program of position record in the end, and the space of the program of deleting greater than fiducial time of appointment (with the corresponding value of typical broadcast time of general programs, for example 60 minutes) the space time, carry out to assemble the operation of white space.If record/playback apparatus does not obtain to be used for the specific setting of logging mode there from the user, just then can carry out the computational process of the writing time that is used for the space of deleting by the logging mode that uses automatic setting.For example, when the user does not provide specific setting that is used for logging mode, calculate the space size of the program of deleting, and correspondingly estimate the usable record time based on the hypothesis of EP pattern.
Therefore, if the space of deleting can hold a typical broadcast program, then as mentioned above by this broadcast program is merged in the continuous white space, just can avoid a kind of like this situation, promptly, be used to hold a program although obtained sizable space, but the disc of the form that the recording occurring continuously piece is managed as single recorded program (for example, DVD+R) tape deck of enterprising line item still face because of by opening entry in last white space rather than internally white space opening entry video data the not enough record that causes of last white space occurs and problem such as end maybe can not write down.
In the embodiment of Fig. 7,, carry out the operation of assembling white space when the space size of the inside program of being deleted during greater than the space size of the time of appointment; In another embodiment of the present invention, when white space and the program deleted are adjacent, and the big or small sum of the white space and the program of delete is greater than the space of stipulated time when big or small, the gathering of execution white space.In yet another embodiment of the present invention, when the big space at fixed time of total big or small sum (but not single size of deleting program) of the deletion space that program produced size and existing white space is big or small, can carry out the gathering of white space.
In another embodiment of the present invention, microcomputer 30 is no longer automatically carried out the operation of assembling white space when the user deletes specific program and meets a certain condition, but as shown in Figure 8, microcomputer 30 can show the current whole usable record time that is used for continuous recording up duration (the usable record time that is used for last white space) and obtains by gathering white space (this comprises the white space that the deletion recorded programs produces) by OSD unit 33, and inquire whether carry out the operation of assembling white space, when accepting, just carry out the operation of gathering white space as response user to this inquiry.Therefore, when the user wants to ask tape deck to carry out another operation at once after the deletion specific program, check the user to assembling the request of operating of white space by comprising, this device can be avoided the unnecessary wait that causes because of the operation that automatically performs the gathering white space.
In another embodiment of the present invention, automatically carry out the operation of assembling white space under the situation that a certain condition satisfies when the user deletes specific program, and receive in the operating period of assembling white space and (for example to stop this request of operating, the request of reproducing recorded program) microcomputer 30 can show guidance information, the operation of this information representation gathering white space is carried out, and just can carry out institute's requested operation after the operation of assembling white space is finished.Assembling after white space and relevant navigation information file thereof upgrade, automatically carry out institute's requested operation.
The present invention according to above-detailed, require the disk media of continuous space for the program that is write down, the white space of recording medium is fully utilized, thereby (for example can write down hourage video content as much as possible, broadcast program), therefore improved the utilization rate of recording medium.
The present invention is not limited to aforesaid preferred embodiment, those skilled in the art will readily appreciate that, can utilize the present invention and the various embodiment of the improvement, modification, replacement or the interpolation that have within the scope of the invention.If these improvement, modification, replacement or interpolation belong to the defined scope of the present invention of appended claims, then its spirit also should be regarded as belonging to the present invention.
