Apparatus and methods for video distribution via networks

摘要

Apparatus for video distribution to receiving units (6) over a network N. The apparatus comprises a distribution unit (4) at which video signals are compressed for transmission using intraframe and interframe coding, and at least one intermediate unit (10) disposed in a signal path between the distribution unit (4) and one or more receiving units (6). The intermediate unit (10) is arranged for storing intraframe coded signals and supplying such stored signals to one or more receiving units (6) when predetermined conditions are satisfied.
