Abstract
Audio information is stored on a unitary storage medium with a Table-of-Contents (TOC) mechanism for therein specifying an actual configuration of various audio items on the medium. In particular, one or more Sub-TOCs are each assigned to a respective different audio format. A single Master-TOC is provided for specifically pointing to each Sub-TOC.
Claims14
A method comprising acts of:
- providing audio-centered information;
- producing a Table-of-Contents (TOC) specifying an actual configuration of various audio items on a unitary medium, including:
- providing two or more sets of one or more Sub-TOCs of a plurality of differently standardized audio formats, and
- providing a single Master-TOC for specifically pointing to each of said Sub-TOCs;
- and
- storing the Master-TOC at a location on the unitary medium and storing at least one set of the two or more sets of Sub-TOCs in a different location on the unitary medium from the location of the Master-TOC.
A unitary medium comprising:
- audio-centered information;
- a Table-of-Contents (TOC) specifying an actual configuration of various audio items on said medium, including:
- one or more Sub-TOCs assigned to each of a plurality of differently standardized audio formats;
- and
- a single Master-TOC for specifically pointing to each of said Sub-TOCs, wherein
- at least one of said Sub-TOCs and associated audio-centered information is stored in a different location than the location of the Master-TOC.
A reader device for interfacing to a medium, the device comprising:
- retrieving means for retrieving data stored on the medium;
- selecting means for selecting a subset of the retrieved data;
- buffering means for buffering the subset of the retrieved data and passing on the buffered data at a pre-selected rate to decompressing and decoding means;
- and
- wherein said retrieving means, said selecting means, said buffering means and said decompressing and decoding means are each adapted to handle data stored on the medium, said data including:
- audio-centered formation;
- a Table-of-Contents (TOC) specifying an actual configuration of various audio items on the medium, including:
- one or more Sub-TOCs assigned to each of a plurality of differently standardized audio formats, and
- a single Master-TOC for specifically pointing to each of said Sub-TOCs, wherein at least one of the Sub-Tocs is in a different location on the medium from the location of the Master-TOC.
A method for storing audio-centered information on a unitary storage medium while using a non-hierarchical Table-of Contents (TOC) mechanism for therein specifying an actual configuration of audio items on said unitary medium, comprising acts of:
- assigning one or more Sub-TOCs to each of a plurality differently standardized audio formats, and furthermore providing a single Master-TOC specifically pointing to each of said Sub-TOCs, and each Sub-TOCs specifying an actual configuration of audio items on said medium for the respective audio format;
- and
- storing the Master-TOC at a location on the unitary medium and storing at least one of the Sub-TOCs in different location on the unitary medium from the location of the Master-TOC.
A unitary medium having stored thereon audio-centered information and a non-hierarchical Table-Of-Content for therein specifying an actual configuration of audio items on said unitary medium, wherein the Table-Of-Contents comprises:
- one or more Sub-TOCs assigned to each of a plurality of differently standardized audio formats, and
- a single Master-TOC for specifically pointing to each Sub-TOC, and
- wherein each Sub-TOC specifies an actual configuration of audio items on said unitary medium for the respective audio format assigned thereto, and wherein at least one of Sub-TOCs is stored in a different location on the unitary medium from the location of the Master-TOC.
