FIELD: information technology.
SUBSTANCE: invention relates to increasing error tolerance in standard H.264/advanced video coding (AVC) and scalable video coding (SVC). A system of modifying error resiliency features by conveying temporal level 0 picture indices, such as tl0_pic_idx, within a supplemental enhancement information (SEI) message instead of optionally including them in the network abstraction layer (NAL) unit header is provided. Furthermore, a mechanism is provided for enabling repetition of SEI messages in teal-time transport protocol (RTP) packets. Such repetition of SEI messages facilitates detection of lost temporal level 0 pictures on the basis of any received packet.
EFFECT: improved method of increasing error tolerance in AVC and SVC standards.
