Abstract
Methods and systems for storage and playback of broadcast media received via a local digital video recording (DVR) system. The system includes the DVR system configured to receive the broadcast media and upload the broadcast media to a storage server over a network. The DVR system divides the broadcast media content into blocks and assigns a unique block ID to each block based on the block data. Prior to uploading each block to the storage server, the unique block ID is sent to the storage server, which only uploads and stored the block if a duplicate block has not already been stored on the storage device, minimizing network demand. A transcoding server coupled to the storage server transcodes the broadcast media content for streaming over the network.
