Filed:

Sep 20, 2012

Appl. No.:

13/623771

Inventors:

General Instrument Corporation - Horsham PA, US
Mark R. Magee - Campbell CA, US

Assignee:

GENERAL INSTRUMENT CORPORATION - Horsham PA

International Classification:

H04L 29/06

US Classification:

709231

Abstract:

This disclosure describes and adaptive bit rate encoding and distribution techniques for conserving bandwidth usage in a channel. The invention comprises, an encoder or transcoder, a video fragmenter, a video-quality analyzer that output complexity values, a streaming server, a process by which individual fragments are selected for distribution, a video-quality threshold, and, optionally a bandwidth reclamation factor. A video-quality analyzer inspects any combination of the input and output of the encoder, transcoder, or fragmenter, and produces a video-quality metric for each fragment. A fragment-selection process responds to request from a client device. If the video-quality value of the fragment requested exceeds the video-quality threshold, a different fragment having a lower vide-quality value is selected instead. Otherwise, the fragment that would have been selected is selected. In some embodiments, the video-quality threshold can be dynamically adjusted to permit varying amounts of bandwidth reclamation.

Abstract:

A method and apparatus for an adaptive bit rate system. The method may include streaming media content at a server, determining a discontinuity in the streaming media content based on boundaries corresponding to changes in the streaming media content, and dividing the streaming media content into a plurality of variable duration segments, wherein a duration of one of the plurality of variable duration segments is to be adjusted based on the determined discontinuity to cause the one of the plurality of variable duration segments to end at the determined discontinuity in the streaming media content. The method may further include transmitting the plurality of variable duration segments of the streaming media content from the server.
