Problems solved by technology

One problem with conventional digital video recorders is that the network used to transmit content from the digital video recorder is susceptible to bandwidth reductions, such as those caused by congestion and / or interference
These bandwidth reductions often result in unacceptable degradation of the content communicated over the network and presented to the user

Abstract

A video server (102), video client (104), methods (600, 700), and computer programs are provided for partitioning and presenting video content. A partitioning method (600) and a video server (102) partition video content into multiple layers before storage of the video content. At least some of the multiple layers of the video content are then retrieved and provided for presentation. A presenting method (700) and video client (104) receive and combine at least some of the multiple layers of the video content into a video data stream. The video data stream is decoded, and a video signal is provided for presentation on a display device.

Description

technical field [0001] The present invention relates generally to video encoding systems, and more particularly to systems and methods for layered digital video encoding in digital video recorders. Background technique [0002] Digital video recorders (DVRs) are becoming more and more common in the United States and around the world. Digital video recorders, also known as personal video recorders (PVRs) and personal television recorders (PTRs), record television programs, movies and other content on digital storage media such as hard drives. The recorded content is then retrieved from the storage medium and presented to the user of the digital video recorder. [0003] Conventional digital video recorders often allow users at remote locations to find content stored on the digital video recorder. For example, a user may watch a movie on a television in one room while the movie is stored on a digital video recorder in another room. Content from digital video recorders is typ...
