Software carrier with operating commands embedded in data blocks

A player for playing a compatible optical disk that represents a program containing audio and/or visual components;

• said components being represented on the disk in the form of digital data streams organized in a series of data blocks with each data block containing bits of one or more data streams and the number of bits of each data stream within a data block being variable such that the bit-use rates of the data streams are independent of each other, the bits in the data streams being distributed in the data blocks on said optical disk such that, after being read from the disk and buffered, bits are at all times available as required for proper reconstruction of the respective audio and/or visual components, the same data blocks that contain bits reprepsenting said audio and/or visual components further containing commands interleaved therewith that specify how said player is to process said components, the bits in said data streams and said commands having positions in the data blocks that are not predetermined and that may vary from one data block to another;
• the player comprising buffer means for each of said data streams, means for reading the data blocks on an optical disk and for distributing the bits of each data stream to a respective buffer means, means for generating the respective audio and/or visual components from the bits in said buffer means, and means for reading commands in said data blocks and for processing accordingly the bits in said buffer means.
