Methods and apparatus for use of compact concurrent codecs in multimedia communications

An apparatus for initiating a multi-party, multi-stream conference that employs a plurality of codecs, the apparatus comprising:

• a processor configured to generate a first message for transmission to a first device;
• and
• a receiver configured to receive a second message from the first device for establishing a conference, the second message including a list of one or more concurrent codec capabilities supported by the first device, wherein the list of one or more concurrent codec capabilities supported by the first device comprises an indication of whether one or more resources usable for one or more concurrent instances of a first listed codec may instead be used for one or more concurrent instances of a second listed codec.

A non-transitory computer readable medium comprising instructions that, when executed, cause a processor to perform a method of:

• generating, at a first device, a first message for transmission to a second device;
• and
• receiving, at the first device, a second message for establishing a conference, the second message including a list of one or more concurrent codec capabilities supported by the second device, wherein the list of one or more concurrent codec capabilities supported by the second device comprises an indication of whether one or more resources usable for one or more concurrent instances of a first listed codec may instead be used for one or more concurrent instances of a second listed codec.
