Abstract

A system and method for switching between multiple encoders or decoders may be implemented to quickly and seamlessly transfer coding operations between two encoders. Before switching from a first encoder to a second encoder, the second encoder is initialized and updated with a copy of the necessary information from the first encoder. Similarly when switching from a first decoder to a second decoder, the second decoder is initialized and the necessary information from the first decoder is passed to the second decoder. A controller may monitor the system to identify a condition that would trigger an encoder switch and identify the encoder that best suits the system conditions. A shared memory unit accessible by either encoder may store the initialization information. A shared decode unit accessible by either encoder may transmit decoded frames between encoders.
