Tiivistelmä

Some video applications work with parallel bitstreams however only parts of them are required. Decoding the streams entirely might be prohibitive due to high number of video streams and / or high resolution or bitrate of the streams. In such cases, a random access also referred as to partial decoding has to be supported. It can be achieved with a conforming decoder, if the video is separated into individual slices, and the unnecessary slices are dropped from the bit stream. Such a feature is essential in 3D lightfield displays in which partial decoding of bitstreams helps providing less complex and thus real-time decoding and processing. This paper studies the problem of creating self-contained (i.e., independently decodable) slices in an H.264 stream. The requirements that need to be fulfilled in order to build selfcontained slices are described, and an encoder-side solution is proposed. The advantages of self-contained slices are examined in the context of a light-field rendering application that relies on partial decoding.
