1. A method comprising:
- identifying, using a processor, a parameter set table that associates sequence parameter set (SPS) identifiers and picture parameter set (PPS) identifiers;
receiving a network abstraction layer unit stream including video data;
identifying a PPS from the network abstract layer unit stream;
accessing the parameter set table using an identifier from the PPS received in the network abstract layer unit stream; and
retrieving an SPS from the parameter set table.

Abstract
In one implementation, multiple parameter sets associated with different resolutions for a media stream are identified. A parameter set table including the plurality of parameter sets and associated resolutions is generated. After, establishing a communication session with an endpoint, the parameter set table is sent to the endpoint as part of the communication session. Also through the same communication session, video data of the media stream is sent to the endpoint.

20. An apparatus comprising:
-
a processor; and a memory comprising one or more instructions executable by the processor to perform; identifying a sequence parameter set (SPS) identifier and a picture parameter set (PPS) identifier; adding an entry to a parameter set table, the entry including the SPS identifier and the PPS identifier; establishing a network abstraction layer unit stream including video data; and sending the parameter set table in associated with the network abstraction layer unit stream including video data.
