Abstract

A disclosed methodology for processing language descriptors includes receiving streaming multimedia content that includes initial language descriptors. Portions of the multimedia content stream are encapsulated into packets that include an indication of the initial language descriptors. Later in time, further language descriptors are received with the streaming multimedia content. As a series of packets created from the multimedia content stream are processed, the indication of received language descriptor is adapted to account for any change in the language of audio tracks received with the streaming multimedia content.

Claims

1. A non-transitory computer readable medium storing program instructions, executable by a processor, wherein the program instructions, when executed by the processor, perform operations comprising:

identifying an initial language descriptor received with streaming content;

indicating the initial language descriptor in a packet, wherein the packet corresponds to a portion of the streaming content; and

upon detecting a change from the initial language descriptor to a second language descriptor, providing an indication of the second language descriptor in a subsequent packet, wherein the subsequent packet corresponds to a chronologically subsequent portion of the streaming content.

2. The computer readable medium of claim 1, wherein the streaming content is an analog stream and wherein the operations include:

digitizing the analog stream into a digital bit stream.

3. The computer readable medium of claim 1, wherein the operations include:

compressing the streaming content.

4. The computer readable medium of claim 1, wherein the packet includes a header, wherein the header includes the indication of the language descriptor.

5. The computer readable medium of claim 1, wherein the header further includes a program identifier.

6. The computer readable medium of claim 4, wherein the packet further includes a payload, wherein the payload includes a plurality of transport stream packets.

7. The computer readable medium of claim 1, wherein encapsulating the streaming content into a plurality of packets occurs at least partially at a real-time transport protocol layer.

8. The computer readable medium of claim 7, wherein a further portion of encapsulating the streaming content into a plurality of packets occurs at least partially at a user datagram protocol layer.

9. An encoder, comprising:

an input for receiving a content stream that includes an initial language descriptor value indicative of a language associated with an audio component of an initial portion of the content stream; and

a processor for encapsulating streaming content into a series of packets, wherein individual packets of a first portion of the series of packets include a packet header with an indication of the initial language descriptor value, wherein the processor is further for adapting further packet headers associated with a subsequent portion of the series of packets to include a further indication of a second language descriptor.

10. The encoder of claim 9, wherein the content stream is received as an analog stream, wherein the processor is further enabled for digitizing the analog stream.

11. The encoder of claim 10, wherein the processor is further enabled for compressing the multimedia content bit stream.

12. The encoder of claim 9, wherein individual packets of the first portion of the series of packets include a plurality of transport stream packets.
