Embodiment 1
[0042] The information recording medium (D11 for short) of the multi-standard program of the present invention, namely: D11 disk, including D11 optical disk, D11 magnetic disk, D11 electronic disk and D11 magnetic tape, etc. The following contents are: partition table, multiple (at least two) program compressed data, multiple (at least two) program navigation information, and may also include system navigation information. The system navigation information can also be stored in the corresponding playback device, and the partition table includes the system files of the D11 disk.
[0043] The program compressed data, namely the data layer, is a data file formed by compressing the program source through the same or different compression methods, and the program can be a VCD movie, DVD movie, SVCD movie, CD audio program, MP3 audio program, Still pictures, video games, etc. contain at least one video and / or audio data file. Of course, the compression formats of the compressed dat...
Embodiment 2
[0050] Other conditions are identical with embodiment 1, just increase following content:
[0051] 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.
[0052] Correspondingly, in the system navigation i...
Embodiment 3
[0062] 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 shown in Figure 2. In the recording process, after the program source is produced mainly through the host computer or multiple network host computers, it is output to the recording information medium (D11 disk) through the recording output device, as shown in Figure 2 The flow chart of is a relatively complete recording process. The following is a further description of the process:
[0063] 1) Judging whether to add a new program source;
[0064] 2) If otherwise, go to step 11;
[0065] 3) If step 1 is yes, obtain the paths of different selected program sources and store them in the program source table;
[0066] 4) read in the first program source in the program source table;
[0067] 5) Select a compression coding ...
