File format based streaming with dash formats based on LCT

A device for receiving media data, the device comprising:

• one or more media decoders configured to decode media data;
• a network interface configured to receive a layered coding transport (LCT) Session Instance Description (LSID), wherein the LSID includes information representative of a plurality of LCT sessions, each of the LCT sessions including data of a respective one of a plurality of representations of a Dynamic Adaptive Streaming over HTTP (DASH) media presentation and data of one or more of the LCT sessions;
• and
• a processor configured to:
• initiate consumption of one or more of the representations of the DASH media presentation based on:
• 1) use of the LSID and 2) without use of a manifest file to generate a request for a portion of data of the one or more representations of the DASH media presentation, wherein to initiate consumption, the processor is configured to:
• receive, via the network interface, a first set of data including packets of the LCT sessions including the portion of the data of the one or more of the representations up to a first playback time;
• and
• provide data of the packets to the one or more media decoders;
• after receiving the first set of data, receive the manifest file;
• and
• receive a second set of data, different from the first set of data, of the DASH media presentation using the manifest file, the second set of data having playback times following the first playback time.

A device for receiving media data, the device comprising:

• means for determining a plurality of representations of a Dynamic Adaptive Streaming over HTTP (DASH) media presentation from a layered coding transport (LCT) Session Instance Description (LSID), wherein the LSID includes information representative of a plurality of LCT sessions, each of the LCT sessions including data of a respective one of the representations;
• means for initiating consumption of one or more of the representations of the DASH media presentation based on 1) use of the LSID and 2) without use of a manifest file to generate a request for a portion of data of the one or more representations of the DASH media presentation, wherein the means for initiating consumption comprises:
• means for receiving a first set of data including packets of the LCT sessions including the portion of the data of the one or more of the representations up to a first playback time;
• and
• means for providing data of the packets to a media decoder;
• means for receiving the manifest file after receiving the first set of data;
• and
• means for receiving a second set of data, different from the first set of data, of the DASH media presentation using the manifest file, the second set of data having playback times following the first playback time.

A computer-readable storage medium having stored thereon instructions that, when executed, cause a processor of a device for receiving media data to:

• determine a plurality of representations of a Dynamic Adaptive Streaming over HTTP (DASH) media presentation from a layered coding transport (LCT) Session Instance Description (LSID), wherein the LSID includes information representative of a plurality of LCT sessions, each of the LCT sessions including data of a respective one of the representations;
• initiate consumption of one or more of the representations of the DASH media presentation based on:
• 1 use of the LSID and 2) without use of a manifest file to generate a request for a portion of data of the one or more representations of the DASH media presentation, wherein the instructions that cause the processor to initiate consumption comprise instructions that cause the processor to:
• receive a first set of data including packets of the LCT sessions including the portion of the data of the one or more of the representations up to a first playback time;
• and
• provide data of the packets to a media decoder;
• after receiving the first set of data, receive the manifest file;
• and
• receive a second set of data, different from the first set of data, of the DASH media presentation using the manifest file, the second set of data having playback times following the first playback time.

A method of sending media data, the method comprising:

• constructing a layered coding transport (LCT) Session Instance Description (LSID) including information representative of a plurality of LCT sessions, each of the LCT sessions including data of a respective one of a plurality of representations of a Dynamic Adaptive Streaming over HTTP (DASH) media presentation, wherein the LSID indicates correspondences between the LCT sessions and the representations;
• outputting the LSID;
• outputting, without reception of a request for data of the representations that is based on a manifest file, a first set of data including the data of the representations in the corresponding LCT sessions up to a first playback time;
• after outputting the first set of data, outputting the manifest file;
• and
• outputting a second set of data, different from the first set of data, of the DASH media presentation in response to one or more requests based on the manifest file, the second set of data having playback times following the first playback time.

A device for sending media data, the device comprising:

• a network interface for outputting data of a plurality of layered coding transport (LCT) sessions;
• and
• a processor configured to:
• construct an LCT Session Instance Description (LSID) including information representative of a plurality of LCT sessions, each of the LCT sessions including data of a respective one of a plurality of representations of a Dynamic Adaptive Streaming over HTTP (DASH) media presentation, wherein the LSID indicates correspondences between the LCT sessions and the representations;
• output the LSID via the network interface;
• output, without reception of a request for data of the representations that is based on a manifest file, a first set of data including the data of the representations in the corresponding LCT sessions via the network interface up to a first playback time;
• after outputting the first set of data, output the manifest file;
• and
• output a second set of data, different from the first set of data, of the DASH media presentation in response to one or more requests based on the manifest file, the second set of data having playback times following the first playback time.
