Problems solved by technology

[0002] Ordinary information recording media can only store programs of one compression format, such as CD discs, DVD discs or VCD discs, etc. Since the navigation of the information recording media uses fixed headers to identify programs, programs of other formats or new formats No applicability, thus greatly limiting the versatility of information recording media
And for different information recording media, only the corresponding player can be used to play, and the player lacks the compatibility of programs of various compression formats
[0003] With the development of technology, programs of various new compression formats are constantly emerging, such as: H.264, HDV instead of MPEG2, AAC instead of MP3, etc., which requires people to constantly update their playback when playing new format programs opportunity, will cause a great waste of resources
[0004] Moreover, the existing compressed program is an integral structure, which cannot be easily re-edited and re-cut, so that flexible linking and control cannot be realized, which also limits the possibility of further processing the program content

Embodiment 1

[0039] The information recording (D11 for short) medium of the multi-system program of the present invention, namely: D11 dish, comprises media such as D11 optical disk, D11 magnetic disk, D11 electronic disk and D11 magnetic tape, is stored on described D11 dish and comprises such as figure 1 The following contents are shown: partition table, multiple (at least two) program compressed data, multiple (at least two) program navigation information, and system navigation information may also be included. The system navigation information can also be stored in the corresponding playing device, and the partition table includes the system files of the D11 disc.

[0040] The program compressed data, that is, the data layer, is a data file compressed by the program source through the same or different compression methods. The program can be a VCD movie, a DVD movie, an SVCD movie, a CD audio program, an MP3 audio program, Still pictures, video games, etc. Data files containing at leas...

Embodiment 2

[0047] Other conditions are identical with embodiment 1, just increase following content:

[0048] The compressed and encoded program is defined as a plurality of segments, and in the plurality of program navigation information, the number of segments, the starting address, and the natural attributes of each segment are stored, such as: resolution, starting offset address , end offset address, time length and other information. Specifically: in order to divide the program into smaller segments, according to the memory of the player, it is best to divide the program into multiple segments according to the principle that each segment contains at least one key frame, such as: 1024 segments, and each The natural attributes of the segments are recorded in the corresponding program navigation information, so that the compressed data of each program is divided into several segments, and each segment can be processed on this basis.

[0049] Correspondingly, in the system navigation i...

Embodiment 3

[0059] The recording method of the information recording medium described in Embodiment 1 or Embodiment 2 is a method of making the program source into a D11 program and recording it on the information recording medium (D11 disk). The specific flow chart is as figure 2 As shown, in the recording process, after the program source is produced mainly through the computer mainframe or multiple network computer mainframes, it is output to the recording information medium (D11 disc) through the recording output device, figure 2 The flow chart shown is a relatively complete recording process, which is further explained below:

[0060] 1) Judging whether to add a new program source;

[0061] 2) If otherwise, go to step 11;

[0062] 3) If step 1 is yes, obtain the paths of different selected program sources and store them in the program source table;

[0063] 4) read in the first program source in the program source table;

[0064] 5) Select a compression coding method, and compr...

Abstract

The invention discloses a multi-system information recording medium, stored with a partition table, plural program compressed data, and program navigation information and system navigation information for each program, where the program compressed data are defined into plural segments in the program navigation, and the control definition of the program segments is made in the system navigation information. The invention also discloses the information playing method and device for the multi-system information recording medium, compatibly playing other-system recoding medium. The multi-system information recording medium allows multi-system compressed data to exist in the same medium and they can all be played on the playing device of the invention, more convenient for the user.

Description

technical field [0001] The present invention relates to an information recording medium, an information recording device (recorder) and a recording method for the above information recording medium, and an information playback device (player) and playback method for playing the above information recording medium. Background technique [0002] Ordinary information recording media can only store programs of one compression format, such as CD discs, DVD discs or VCD discs, etc. Since the navigation of the information recording media uses fixed headers to identify programs, programs of other formats or new formats There is no applicability, thus greatly limiting the versatility of the information recording medium. And for different information recording media, can only be played with corresponding player, and player lacks the compatibility to the program of various compression formats. [0003] With the development of technology, programs of various new compression formats are ...
