Abstract

Techniques for efficient significant coefficients coding in scalable video codecs are described. In one configuration, a device including a processing circuit having a set of instruction operative to generate initialization tables for a current frame or slice is provided. The initialization tables have statistics of a significant coefficient pass for a previous encoded frame or slice using scalable video coding. The device also includes a transmitter to transmit the initialization tables with the current frame or slice to a decoder. The decoder can decode a frame or slice with the transmitted initialization tables. The decoder may also use resident default initialization tables.
