System and method for providing and using predetermined signaling of interoperability points for transcoded media streams

A non-transitory computer-readable medium storing computer code, that when executed, causes an apparatus to:

• encode a video sequence into a scalable encoded bitstream comprising a plurality of layers, the scalable encoded bitstream comprising network abstraction layer (NAL) units, each NAL unit comprising a NAL unit header and a NAL unit payload;
• and
• provide a signaling corresponding to a scalable layer of the plurality of layers, the signaling including information identifying a transcoding process and a coding property, wherein the transcoding process, when applied to the scalable layer after encoding, modifies the NAL unit headers of the NAL units associated with the scalable layer, discards the NAL units associated with other scalable layers, and results in a non-scalable transcoded media stream, and wherein the coding property characterizes the transcoded media stream and comprises at least one of a coding format, a profile of a standard, a level of a standard, a hypothetical reference decoder parameter, and a video buffer verifier parameter.

A non-transitory computer-readable medium storing a data structure associated with a scalable encoded bitstream, said data structure comprising:

• at least one syntax element associated with a transcoding process and a coding property characterizing a transcoded media stream resulting when the transcoding process is applied to one of a plurality of layers of the scalable encoded bitstream, the scalable encoded bitstream comprising network abstraction layer (NAL) units, each NAL unit comprising a NAL unit header and a NAL unit payload, wherein the transcoding process modifies the NAL unit headers of the NAL units associated with said one of the plurality of layers, discards the NAL units associated with other scalable layers of the plurality of layers, and results in a non-scalable transcoded media stream, and wherein the coding property comprises at least one of a coding format, a profile of a standard, a level of a standard, a hypothetical reference decoder parameter, and a video buffer verifier parameter.
