Abstract:
A system and method of modifying error resiliency features by conveying temporal level 0 picture indices, such as tl0_pic_idx, within an SEI message instead of optionally including them in the NAL unit header is provided. In addition, a mechanism is provided for enabling repetition of any SEI messages in Real-Time Transport Protocol (RTP) packets. Enabling such repetition of any SEI messages facilitates detection of lost temporal level 0 pictures on the basis of any received packet.
