Synchronization-predictive coding for video compression: the SP frames design for JVT/H.26L

This paper discusses the new frame types considered for the video coding standard JVT/H26L developed jointly by ITU-T VCEG and ISO-IEC MPEG. The new frame types are called SP and SI-frames and provide functionalities in bitstream switching, splicing, random access, fast forward, fast backward and error resilience/recovery. Specific applications are illustrated as examples on how the properties of SP and SI-frames can be exploited. Later, detailed descriptions of SP and SI-frame decoder and encoder are provided.
