ABSTRACT:
In a digital video system, high availability distribution is provided using spare modules such as an integrated receiver decoder, multimedia transcoder and streaming module in support of the primary modules. The primary modules multicast status messages which are monitored by the spare modules. When failure of a primary module is detected, the spare module takes over the role of the failed module, for example by joining the same multicast groups as the failed module and taking over processing of the streams of the failed module. Multiple redundancy schemes are described.
