Method and system for PVR on internet enabled televisions (TVs)

摘要

A media playback device may be operable to determine whether replacement media content corresponding to at least a portion of a received broadcast media stream is available during reception of the broadcast media stream from one or more broadcast sources. At least some of the replacement media content may then be retrieved when personal video recording (PVR) operations are requested during play of the received broadcast media stream, to enable seamless performance of the requested PVR operations using at least a portion of the retrieved replacement media content. Exemplary PVR operations may comprise pausing, fast forwarding, and/or rewinding. The replacement media content may be retrieved from a plurality of local and/or remote replacement servers. Availability of replacement media content, from remote replacement servers, may be determined based on programming data in said broadcast media stream, routing information provided by a broadcast source, and/or by inquiry via one or more cataloguing servers.

1. A method for video processing, the method comprising:
during reception of a broadcast media stream from one or more broadcast sources, determining whether replacement media content corresponding to at least a portion of the broadcast media stream is available from a replacement media server; retrieving at least some of the replacement media content from the replacement media server when a personal video recording (PVR) operation is requested during play of the broadcast media stream; and performing the PVR operation directly on at least a portion of the replacement media content retrieved from the replacement media server in place of a corresponding portion of the broadcast media stream, wherein the at least portion of the retrieved replacement media content and the corresponding portion of the broadcast media stream being replaced with during the PVR operation are directed to same video content such that the PVR operation that is performed on the at least portion of the retrieved replacement media content appears to be performed directly on the corresponding portion of the broadcast media stream.
