US 2018/0007439 A1 · SYSTEMS AND METHODS FOR DIGITAL MEDIA STORAGE AND PLAYBACK

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.

Claims20

Dependent claims

An uploader module for a digital media storage device, the uploader module configured to receive a stream of broadcast media content having a plurality of PTS boundaries and perform the steps of:

parse the stream for a first PTS boundary occurring in the stream, the first PTS boundary having a first PTS location;
determine a first grid location upstream of and relative to the first PTS location;
determine a second grid location downstream of and relative to the first PTS location;
parse the stream for a PTS boundary immediately downstream of the second grid location and having a second PTS location;
and
define a first block of the stream bounded by the first PTS location and the second PTS location.
