Figure 16 is the flow chart according to the reproducting method of third embodiment of the invention.With reference to Figure 16, reader 4 reads MPEG TS stream in step 1601 from coiling 400 program area, and outputs it to REMUX67 and DEMUX 60.In step 1602, reader 4 reads the PMT configuration information from coiling 400 navigation data area, and video transitional information extractor 6 generates the PMT bag according to the PMT configuration information, and the PMT bag is offered REMUX 67.REMUX 67 is multiplexed as digital signal in step 1603 with MPEG TS stream and PMT bag.DEMUX 60 is decomposed into video data, voice data, hypertext data and program information data in step 1604 with MPEG TS stream multichannel.Filter 65 is carried out filtering in step 1605, to export required hypertext data and program information data.Video transitional information extractor 6 provides video transitional information (video conversion described symbol) to give Video Decoder 61 in step 1606.Video Decoder 61 is at step 1607 reference video transitional information (video conversion described symbol) decode video data, so that video data can have initial resolution.Audio decoder 62 is at step 1608 decoding audio data, and the voice data of decoding is exported to audio output device (loud speaker).Hypertext data decoder 63 is at step 1609 decoding hypertext data.Blender 64 mixes video data of being decoded and the hypertext data of being decoded in step 1610, and the result that output mixes gives the display device (not shown).Therefore, video data and hypertext data can show with initial condition.
Above-mentioned record and reproducting method may be embodied as computer program.Code and the code segment of forming this program can easily be drawn by the computer programmer of this area.In addition, described program is recorded on the computer-readable medium.This program is read and is carried out by computer, thereby realizes the method for record and reproduction MPEG broadcast program.Computer-readable medium can be magnetic recording media, optical recording media or carrier media.
As mentioned above, according to the present invention, even with the video data that has been different from initial coded system recompile, also correctly reproducing video data and hypertext data.
Claims (2)
1. the method for a recording video data in information storage medium, this method comprises:
Video data to initial code is decoded;
To be different from the video data that initial coded system coding is decoded;
Generation comprises the initial resolution of video data of initial code and the video transitional information of the ratio of width to height;
The video transitional information that generated and the video data of recompile are multiplexed as bit stream; And
This multiplexed bit stream of record in information storage medium.
2. the method for claim 1, wherein the video transitional information is included in the Program Map Table bag.
