Abstract: A system and method of modifying error resiliency features by conveying temporal level 0 picture indices, such as t10_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.

Abstract: Various methods are described for selecting an access method for flexible caching in DASH. One example method may comprise causing a request for at least one of a primary representation for a segment and one or multiple alternative representations for the segment to be transmitted to a caching proxy. The method of this example embodiment may further comprise causing the caching proxy to respond with at least one of the primary representation or the alternative representation based on the caching status at a caching proxy. In some example embodiments, the caching proxy is configured to determine whether the request enables an alternative representation to be included in a response. Furthermore, the method of this example embodiment may comprise receiving at least one of the primary representation or the alternative representation for the segment from the caching proxy. Similar and related example methods, example apparatuses, and example computer program products are also provided.

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.

Abstract: The use of a picture delimiter that is contained in a NAL unit type value that is reserved in the current AVC or SVC specification. The present invention provides the scalability information for the H.264/AVC base layer in such a manner that bitstreams remain decodable with H.264/AVC decoders. In addition, the picture delimiter of the present invention may contain many other syntax elements that can help in easier processing of bitstreams compared to the plain H.264/AVC bitstream syntax.
