Such bitstream structure allows on-line editing, e.g. cut and paste, insertion/deletion, grouping, and special effects. In the interest of ease of editing, AV objects and their composition information are transmitted or accessed on separate logical channels (LCs). Objects which have a lifetime in the decoder beyond their initial presentation time are cached for reuse until a selected expiration time. The system includes a de-multiplexer, a controller which controls the operation of the AV terminal, input buffers, AV objects decoders, buffers for decoded data, a composer, a display, and an object cache. ## Claims ### Claim 1 A method for processing audio data, comprising: receiving in a data bitstream, over time, a plurality of audio information and composition information, wherein said audio information includes one or more objects, each object being individually encoded; processing said composition information received in the data bitstream to compose a single audio arrangement from said audio information; and outputting said single audio arrangement. ### Claim 2 (depends on 1) The method of claim 1, wherein the receiving includes receiving from a network connection. ### Claim 3 (depends on 1) The method of claim 1, wherein the receiving includes receiving from local memory. ### Claim 4 (depends on 1) The method of claim 1, wherein said one or more objects has immediate aural relevancy. ### Claim 5 (depends on 4) The method of claim 4, further comprising storing said audio information in memory. ### Claim 6 (depends on 5) The method of claim 5, wherein said memory is a cache memory. ### Claim 7 (depends on 6) The method of claim 6, further comprising storing said audio information beyond its initial presentation time. ### Claim 8 (depends on 1) The method of claim 1, wherein the outputting further includes outputting the single audio arrangement via a plurality of speakers. ### Claim 9 (depends on 1) The method of claim 1, wherein the outputting further includes transmitting the single audio arrangement. ### Claim 10 A system for processing audio data, comprising: a controller circuit for receiving in a data bitstream, over time, a plurality of audio information and composition information, wherein said audio information includes one or more objects, each object being individually encoded; a composer circuit for processing said composition infoiination received in the data bitstream to compose a single audio arrangement from said audio information; and an output circuit for outputting said single audio arrangement. ### Claim 11 (depends on 10) The system of claim 10, wherein the controller circuit is adapted for receiving from a network connection. ### Claim 12 (depends on 10) The system of claim 10, wherein the controller circuit is adapted for receiving from local memory. ### Claim 13 (depends on 10) The system of claim 10, wherein said one or more objects has immediate aural relevancy. ### Claim 14 (depends on 13) The system of claim 13, further comprising a storage circuit for storing said audio information in memory. ### Claim 15 (depends on 14) The system of claim 14, wherein said memory is a cache memory. ### Claim 16 (depends on 15) The system of claim 15, wherein the storage circuit is further configured to store said audio information beyond its initial presentation time. ### Claim 17 (depends on 10) The method of claim 10, further comprising a plurality of speakers coupled with the output circuit for performing the single audio arrangement. ### Claim 18 (depends on 10) The method of claim 10, further comprising a transmitter coupled with the output circuit for transmitting the single audio arrangement.
