The present invention describes a decentralized symmetric configuration of digital video recorders (DVCRs) for monitoring, controlling, analyzing, recording, playback and streaming of audio/visual (A/V) media over a network. Each DVCR is an autonomous device able to operate in its local environment as well as access and operate another DVCR available on the network to facilitate the overall working of the disclosed system. Each DVCR also exhibits storage fail-safe feature whereby it recovers data automatically if storage media gets corrupted such as due to sudden power failure. A DVCR can be configured to scan the network for other DVCR units. A list of discovered DVCRs is displayed. Each DVCR can access, after authentication, any of the listed DVCR for configuration, monitoring, controlling, recording, playback and other available functionality over the network. The same controls used for operating a local DVCR, including use of buttons, can be employed to operate the remote DVCR, giving a virtual presence at the remote location. The functionality exhibited by each of the DVCR, can be identical. A plurality of the DVCR can thus form a decentralized, symmetric network in which there is no master or central controller.

Decentralized symmetric network of autonomous digital video recorders and its method of use

A method for providing instant replay is disclosed, including receiving a video and an audio stream from a source. Each media unit includes at least one video frame and at least one or more corresponding audio frames which further includes a first video frame that is independently decodable. Each media unit is an independently decodable entity. The media units have a fixed duration. The media units are stored in a memory. A number of starting addresses are stored in a table. The sequence header is retrieved in response to receipt of an instant replay command. Appropriate video and audio decompression engines are selected and configured based on the retrieved sequence header. An instant replay starting address is identified from the table in response to receipt of the instant replay command. One or more media units are retrieved from the memory starting with the media unit associated with the instant replay starting address.
