Description

Data record method, data regeneration device and recording medium

Technical field

The present invention relates in tape decks such as the combined video tape recorder of hard disk/DVD, DVD recorder, DVD Streaming Media register (stream recorder), DVR at least a method, device and recording medium in record regenerating image, sound and the data.

Background technology

In the past, for DVD (Digital Versatile Disc: the video digital various dish), stream related application form, in DVD forum, videograph), the special-purpose DVD-Video of regeneration, record regenerating and editor's DVD-VR (Video Recording: easily easily to playing or transmit DVD-SR (the Stream Recording: the form standardization stream record) that stream carries out direct record regenerating.

DVD-Video is the dish regeneration professional format that film etc. has write down content in advance, and with home theater as main target.DVD-VR is by with the analog video digitlization, and is the form of main purpose with the MPEG-2 encoded recording, and it plays record with simulation and video camera is a main target.DVD-SR is the form of the data that send as mpeg stream of former state record basically, and it directly is recorded as main target with digital broadcast.At present, though DVD-Video spreads all over the world as commodity, DVD-VR also enlarges significantly, and DVD-SR is not commercialization as yet.

Therefore, under situation, mostly just carry out the record of 1 channel by the analog broadcasting of DVD-VR record.That is, only carry out a channel () record for example, NTV (4 channels), or only carry out the record of other channel (for example, TBS (6 channel)).Though DVD-Video is the regeneration professional format, it also goes for record.Under situation, also only carry out the record of 1 channel usually by the analog broadcasting of DVD-Video record.

Open the spy and to have put down in writing this multichannel tape deck and the recording method of writing down a plurality of programs efficiently simultaneously of being used on disc recording medium among the 2001-67802.

For the requirement of the image of recording multi-channel, voice and data etc. simultaneously in DVD, passing through under the situation of the direct recording digital broadcast of DVD-SR, because in digital broadcasting, 1 broadcast wave is made of a plurality of streams, so this form can write down the digital broadcast data of a plurality of streams simultaneously.

But, if carry out the multichannel record simultaneously, then there is following problem according to aforementioned recording method:

Promptly, under situation with DVD-VR or the analog broadcasting of DVD-Video record, though can write down the above audio frequency and video of 2 channels simultaneously, if but (for example write down different mutually channels simultaneously, NTV and TBS), then will be by write down the stream of the NTV behind the 1 second coding in the a-quadrant, the stream of the TBS behind B regional record coding in 1 second afterwards, and this is carried out repeatedly.In this recording mode, need frequently search, under the situation that the medium error rate of other parts worsens, situation that also can the occurrence record mistake.Misregistration is wrong different with regeneration, and retry is very difficult, if carry out record by force, and then further storage delay, and may cause becoming the record collapse state.Further, along with the increase of the numbers of channel such as 3 channel record, 4 channel record, the difficulty of realization increases all the more.

On the other hand, also there is the possibility that to consider on a plurality of channels, to broadcast program in advance with correlation.For example, relay for a football, though considering a channel (for example broadcasts from set out in advance to make arrangements (front stand), NTV), (for example, the program of TBS) broadcasting is when still writing down these at the same time and one other channel is from target network (goalnet), need high-speed synchronous to switch two channels (being NTV and TBS under this situation) during regeneration, this high-speed synchronous and switching are very difficult.

In addition, though it is possible directly the multithread record being carried out in digital broadcasting by DVD-SR, but in this case, because the content of the recorded stream after not knowing to write down, if so analyze content by reading stream, then the user do not know be each channel in multithread, the multichannel the video/audio data record position, record constantly, correlation.

In patent documentation 1, disclose by control and will constitute the control of numerical data intersection record on disc recording medium of 2 mutual different programs, so that program that can recording multi-channel with predetermined data long measure separately.But in the disclosed recording method, the processing when still existing record is than problems such as complexity in the patent documentation 1.

In the 3rd file 602, comprised time map 606.Time map data 606 are that expression transmits the moment of stream 607 and the mapping of the relation between the record position.In addition, in Fig. 6, management data 605 is included in the 1st file 601, and time map data 606 are included in the 3rd file 602, but management data 605 and time map data 606 both also can be included in first file 601.In this case, there is not the 3rd file 602.

In the 2nd file 603, comprised the transmission stream 607,608 of broadcasting by digital broadcasting by the broadcasting station.For transmitting stream 607, as tape deck, can the recorded announce station name, coding format, acoustic coding form, and write down the constantly relevant time map of expression with record position.That is, time map can be used as the management data 605 in the 1st file 601, perhaps time map data 606 records in the 3rd file 602 of time map special use.Time map can comprise any one in management data 605 or the time map data 606.

For transmitting stream 608, as tape deck, though title, coding format, acoustic coding form that can the recorded announce radio station can not write down expression constantly and the time map of the relation of record position.Therefore, in the 1st file the 601, the 3rd file 602 and other file, there are not the time map relevant with transmitting stream 608.

In the 4th file 604, can comprise the indefinite private data 609 of format content.For example comprise the indefinite broadcast data in broadcasting station, broadcasting data in addition or the like.In management data 605, best data of having distinguished in the data that only record is relevant with private data 609, and do not write down other any data.In addition, in the 1st file the 601, the 3rd file the 602, the 2nd file 603, there be not the time map relevant with 609.

Like this, in this embodiment, can the indefinite broadcast data in recorded announce radio station, also private datas such as data beyond the recorded announce simultaneously.

In Fig. 7, show the indefinite stream of format content among Fig. 6 and be recorded in example in the 5th file.

701 is the 1st files, and 702 is the 4th files, and 703 is the 2nd files, and 704 is the 3rd files, and 705 is the 5th files.

In the 1st file 701, comprised management data 706.In management data 706, can write down the information relevant with the transmission stream 708,709 that constitutes the 2nd file the 703, the 3rd file 704 and the 5th file 705 and private data 710.Because the format content of private data 710 is not clear, so even do not write down whole information also can, also cannot write down any other content.Wherein, for management data 706, will be described in detail later.

In the 4th file 702, time map data 707 have been comprised.Time map data 707 are that expression transmits the moment of stream 708 and the mapping of the relation between the record position.In addition, in Fig. 7, though management data 706 is included in the 1st file 701, time map data 707 can be included in the 4th file 702, also management data 706 and time map data 707 boths can be included in the 1st file 701.In this case, the 4th file 702 is thought and is not existed.

In the 2nd, the 3rd file 703,704, comprised the transmission stream 708,709 of broadcasting by digital broadcasting by the broadcasting station.For transmitting stream 708, as tape deck, title, coding format, acoustic coding form that can the recorded announce radio station, and can write down the time map of the relation between express time and the record position.That is, time map can be used as time map data 707 records in management data 706 in the 1st file 701 or special-purpose the 4th file 702 of time map.Time map can be used as in management data 706 or the time map data 707 any one come record.

For transmitting stream 709, as tape deck, title, coding format, acoustic coding form that can the recorded announce radio station, but but can not write down expression constantly and the time map of the relation between the record position.Therefore, in the 1st file the 701, the 4th file 702 and other file, do not exist with transmission and flow 709 relevant time map.

In the 5th file 705, can comprise the not clear private data 710 of format content.It comprises data beyond for example indefinite broadcast data in broadcasting station, the broadcasting or the like.In management data 706, can only write down the data of having distinguished in the data relevant with private data 710, also can not write down any data.In addition, in the 1st file the 701, the 4th file the 702, the 2nd file the 703, the 3rd file 704, there be not the time map relevant with private data 710.

In the embodiment shown in fig. 7, still can obtain the effect same with Fig. 6.

After this, will as the Fig. 4 that transmits stream 1 406, Fig. 5 507,607 or Fig. 7 of Fig. 6 708 as stream with time map, and will as the Fig. 3 that transmits stream 2 304, Fig. 4 407, Fig. 5 508,608 or Fig. 7 of Fig. 6 709 as not having the example of the stream of time map.

To have 1PMT (Program Map Table: part TS Program Map Table) (Transport Stream: transmit stream) be recorded in as 406 among the Fig. 4 that transmits stream 1, Fig. 5 507,607 or Fig. 7 of Fig. 6 708 in, except that. than stream can be recorded in as the Fig. 3 that transmits stream 2 304, Fig. 4 407, Fig. 5 508,608 or Fig. 7 of Fig. 6 709 in.

Here, PMT is called Program Map Table, in the stream of being broadcasted etc., is that the view data, voice data, data playback data, caption data etc. in a kind of business of expression are configured in form where.Usually, in a business, have 1 PMT, but in new from now on broadcasting, it is also conceivable that program with a plurality of PMT.

Though needing the 1st stream is one of them 1PMT part TS,, also can not 1PMT part TS for the 2nd stream.Under the situation that is 1PMT part TS, do not have time map.

The 1PMT part TS that does not have the time map that writes down as the 2nd stream can calculate later time map, and can be defined as the 1st stream with time map again.In this case, recorded stream no longer, but only rewrite management data.

Like this, in this embodiment, management record data is in the 1st file, 1PMT part TS is being flowed as the 1st, when other TS was flowed as the 2nd, the 1st and the 2nd stream was recorded in the 2nd file, and disposes the sign that is used for distinguishing 2 kinds of streams that are recorded in the 2nd file in the 1st file.In addition, flow as the 1st, the stream that does not have time map is flowed as the 2nd, be recorded in the 1st file or the 3rd file with respect to the 1st time map that flows by the stream that will have time map.In this case, management data is all or part of of following content, this content is: the stream format identifying information, expression is 1PMT part TS or the sign of other TS, the PMT number, the multipling channel number of other TS, TS form configuration information, and the broadcasting station information in each channel, the animation data compress mode, the voice data compress mode, the still image data compress mode, the animation data compress mode, expression has or not the sign of time map, expression has or not the sign of time information, expression is the sign of conventional broadcasting stream or storage-type broadcast stream, thereby can be with 1PMT part TS time map to the 1 stream, and pass through, thereby can easily realize recording operation with in multichannel part TS or full TS time map to the 2 streams.

In Fig. 8, show 1 stream that to constitute by stream and be recorded in 1 example in the file with a plurality of PMT.

As shown in Figure 8, by a plurality of inputs 101 via tuner 103, for example, extract the stream that piece 801 extractions have 3 PMT by each stream out by part stream with 1 PMT, and undertaken multiplexing by multiplexing 802, if produce multiplex stream 803, then in multiplex stream 803 with regard to the data of multiplexing different 3 channels.This is for example by multiplexing stream by a plurality of broadcasting stations with different PMT (for example, NTV, TBS, Fuji's TV) broadcasting, thereby becomes the image that constitutes the multiplex stream 803 with 3 PMT.

The multiplex stream 803 of this a plurality of channel multiplexings can be recorded in as the Fig. 3 that transmits stream 2 304, Fig. 4 407, Fig. 5 508,608 or Fig. 7 of Fig. 6 709 in.

In Fig. 9, show other the example that will be recorded in by 1 stream that the stream with a plurality of streams or a plurality of PMT (Program Map Table) constitutes in 1 file.

As shown in Figure 9, by a plurality of inputs 101 via tuner 103, for example, extract piece 901 out by part stream and from each has the stream of 1 PMT, extract stream out with 3 PMT, and undertaken multiplexing and 1PMTization by multiplexing 1PMT piece 902, if produce multiplex stream 903, then in multiplex stream 903 with regard to the data of multiplexing 3 different channels as 1PMT.This just becomes by multiplexing stream by a plurality of broadcasting stations with different PMT (for example, Nippon Television, TBS, Fuji's TV) broadcasting, and constitutes 903 image of stream with 1 PMT.

The multiplex stream 903 of this a plurality of channel multiplexings can be recorded in as the Fig. 4 that transmits stream 1 406, Fig. 5 507,607 or Fig. 7 of Fig. 6 708 in.

And Fig. 8, stream shown in Figure 9 can be multi channel part TS.

Perhaps, Fig. 8, stream shown in Figure 9 can be full TS.

Figure 10 shows full TS.

As shown in figure 10,, extract piece 1001 out by full TS and extract whole IS out, and produce multiplex stream 1002 via tuner 103 by input 101.

Here, so-called full TS, for example, 1 repeater (transponder) that is meant 1 broadcast wave of conduct in the BS digital broadcasting is made of 2 full TS, and 1 full TS wherein is meant that the broadcast wave arrangement that the broadcasting station of the broadcasting station of 1 common broadcast and a plurality of data broadcasting or audio broadcasting is broadcasted is the stream of 1 TS.

That is, full TS becomes the multiplex stream image of for example being broadcasted by the Japanese satellite broadcasting with different PMT, Fuji's satellite broadcasting, independent data broadcasting.

This full TS stream 1002 can be recorded in as the Fig. 3 that transmits stream 2 304, Fig. 4 407, Fig. 5 508,608 or Fig. 7 of Fig. 6 709 on.

In addition, the stream of having described time information in the management data can be recorded in as the Fig. 4 that transmits stream 1 406, Fig. 5 507,607 or Fig. 7 of Fig. 6 708 in.

The stream of not describing time information in the management data can be recorded in as the Fig. 3 that transmits stream 2 304, Fig. 4 407, Fig. 5 508,608 or Fig. 7 of Fig. 6 709 in.

Described time information can be by MPEG (Moving Picture Export Group: mobile motion picture expert group version) Gui Ding PTS (demonstration timestamp).

Described PTS becomes SOB, and (Stream Object: flow object) the final PTS of beginning PTS, SOB, CELL begin all or part of among the final PTS of PTS, CELL.Here, SOB is the record unit that produces when being used for every record and once flowing.In addition, CELL is used for the time by pre-determining SOB or specifies by the user cutting apart or the unit of reference.

In addition, the stream format of transmission stream 1, transmission stream 2 can be known.Here, so-called stream format is that form and country code or one of them are used in expression.Use form and represent broadcast mode belongs to which form in Japanese digital broadcasting (ARIB) form or Britain ATSC form or the European DVB form etc., and country code has represented to write down the code of the country of data.

In addition, it also can be known transmitting stream 1, the image that transmits stream 2 or sound or data format content.Whether for example, transmission flows 1, transmission stream 2 can be distinguished is the form of Japanese digital broadcasting defined.

In addition, for Fig. 6 609,710 the private data of Fig. 7, its stream format can be indeterminate.

In addition, for Fig. 6 609,710 the private data of Fig. 7, image or sound or data format content also can be indeterminate.

And, as transmit stream 2, Fig. 3 304, Fig. 4 407, Fig. 5 508, Fig. 6 608, Fig. 7 709 or as the Fig. 4 that transmits stream 1 406, Fig. 5 507, Fig. 6 607, Fig. 7 708 can be the stream of broadcasting by storage-type broadcast.

Here, so-called storage-type broadcast is when the transmission bit rate existence of common broadcast is more than needed, broadcast with low bit rate by part more than needed, perhaps do not wait when carrying out ordinary playing at dead of night and broadcast, the signal of broadcasting need be stored in the home server in advance, when watching, the bit stream of being stored is with the disposable reproduction of normal speed.

Storage-type broadcast data as the 2nd stream record can be calculated the time map of back, and the 1st stream as having time map can define again.In this case, stream cannot be by record again, and only can rewrite management data.

Below, show 706 among 605 among 505 among 404 among 303 among Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, and management data is described in detail.

In management data, comprise following data.

Dispose the whole or a part of of following content, this content is: stream format identifying information, expression are the part TS of 1PMT or the sign of other TS; It is the common broadcasting stream or the sign of storage-type broadcast stream that broadcast message in multipling channel number among PMT number, other TS, TS form configuration information and each channel, animation data compress mode, voice data compress mode, rest image compress mode, animation data compress mode, expression have or not the sign of time map, sign, the expression that the expression time information has or not.

In addition, therein, represented that the animation data compress mode is MPEG video or the H.264 video or the kind of Windows (landing trade mark) Media video, expression voice data compress mode is mpeg audio or Dolby audio frequency or DTS audio frequency, represents that also the Still image data compress mode is JPEG or PNG.

In management data (HR_MANGR.IFO file),, can show the content of multichannel record data by at least a stream format, TS sign.

Transmit stream 1 by defining like this, transmit stream 2:

Transmit stream 1 and have time map, transmit stream 2 and do not have time map.

Transmitting stream 1 is 1PMT part TS, and transmitting stream 2 is other TS.

Transmit stream 1 and in management data, have PTS, transmit stream 2 and in management data, do not have PTS.

Thus, show each content, thereby can use transmission stream 2 more easily to realize multichannel record, regeneration by management data (HR_MANGR.IFO file).

Even be multichannel record at first,, also can easily realize having the multichannel record of time map by the subsequent calculations time map with time map.

The data structure of the management data shown in aforementioned, data configuration order, sign name, bit number, Bit Allocation in Discrete are different with example.

Both just there be not total data in management data shown in aforementioned, can have the one partial data yet.

The generation unit of management data shown in aforementioned can be that bigger unit also can be less unit.

In addition, these management datas are on being recorded in recording medium the time, suitably recording start address, end address, data length.

Stream is not only to transmit stream, and program stream, PES, ES etc. are too.

In addition, be also contained among the present invention with the data recording equipment of above-mentioned recording method record data or regeneration data regeneration device with the data of above-mentioned recording method record.

In addition, the recording medium that writes down with above-mentioned recording method is also contained among the present invention.

In the above-described embodiments, though the stream that does not have by DVD-Forum official hour mapping is described, the stream that does not have a time map also can be divided into the stream of the table with the due in that is used to represent to broadcast stream and the relation between the recording address and not have the no surface low of these tables.Here, will have the stream of form and do not have the stream of form to be referred to as not limit the stream that must have time map.Below, the stream that is used for having the stream of form and not having a form is described with the method that the stream with time map writes down.

Wherein, though do not illustrate among the embodiment, the stream with time map can be included among the part that does not limit the stream that must have time map.

In the embodiment shown in fig. 12, management record data does not limit the stream that must have time map and is recorded in the 2nd file 1202 in the 1st file of setting as management document 1201.In illustrated embodiment, the 2nd file 1202 is made of the file 1203 of the stream that is used to write down the form with the relation between expression due in and the recording address and the file 1204 that do not have this form.

Further, the list data of the stream of record is stored in the 3rd file 1205 in file 1203.In addition, in the 1st file 1201, as management data, write down sign 1206 in advance, diagram sign 1206 is used to represent to be the stream with each time map, still have to be used to represent to broadcast flow to and reach constantly and the stream of the form of the relation between recording address, also or not have the stream of time map and form.

Player is by reading sign 1206, can know that the 2nd file 1202 is to write down the file that does not limit the stream with time map, in this document, file 1203 is the files that write down the stream of the form with expression due in and recording address relation, and file 1204 is the files that write down the stream of the form with the relation between the expression moment and recording address.Further,, can know in the 3rd file 1205, write down the form that concerns between the due in of the stream that is illustrated in the file 1203 record and the recording address by indicating 1206.

Stream for record in the diagram file 1203 can be carried out simple time search, on the other hand, and for the not time of implementation search of stream of record in file 1204.

Figure 13 illustrates management record data in the 1st file 1301, simultaneously, the stream that must have a time map is recorded in the 2nd later file, further is not recorded in embodiment in other file and do not limit the stream that must have time map.Specifically, illustrated embodiment has management document (the 1st file) 1301, is used to write down file 1302,1303 with time map and the file 1304,1305 that is made of the stream that does not have time map.Further, file 1304 have by record the relation between expression due in and the recording address form stream file 1306 and be used to write down do not have expression constantly and the file 1307 of the stream of the form of the relation between the recording address constitute, file 1305 have by record the relation between expression due in and the recording address form stream file 1308 and be used to write down do not have expression constantly and the file 1309 of the stream of the form of the relation between the recording address constitute.

Further, in the illustrated embodiment, file 1310 and 1311 have been set, also set file 1312,1313, wherein this document 1310 and 1311 has write down the time map data of the stream of record in file 1302 and 1303, and this document 1312,1313 has write down the list data of the stream of record in file 1306,1308.

In addition, each stream of the sign 1314 of record expression are the stream with time map in the 1st file 1301, still have expression broadcasting and flow to and reach constantly and the stream of the form of the relation between the recording address, also or not have in time map and the form any one stream.

Player reads sign 1304, is identified in the stream of record in the file 1302～1309, is identified in time map, the form of record in the file 1310～1313 simultaneously.

Stream for record in file 1302,1303, the time map that use is write down in file 1310,1311 is the time of implementation search correctly, for the stream of record in file 1306,1308, use the list data of file 1312,1313 to carry out time search simply.In addition, for the stream of record in file 1307,1309, not time of implementation search.

As mentioned above, do not limit the stream that must have time map and can be stream, have expression broadcasting and flow to and reach constantly and the stream of the form of the relation between the recording address and do not have expression any one constantly and in the stream of the form of the relation between the recording address with time map, perhaps also can be have the due in of expression broadcasting stream and the relation between the recording address form stream or do not have that expression shows constantly and in the stream of the form of the relation between the recording address any one.According to the definition of above-mentioned stream, also can define sign.

Below, an example according to the sign of stream definition is described.Here, following situation is described, that is: indicate that by this discerning is the stream with time map, still have expression broadcasting and flow to the stream that reaches the form that concerns between the moment and the recording address, also or not have the stream of the form that concerns between time map and expression due in and the recording address.

HR_MANGR_IFO as management document is made of stream file information table (STM AVFIT) and other data.

Stream file information table (STM AVFIT) is made of SOB stream information #1～SOB stream information #n and other.1 record of every execution just produces a SOB stream information.The SOB stream information by STM ATR (Stream Attribute: stream attribute) and other data constitute.

In STMATR, comprise following sign:
