Problems solved by technology

In this case, evenly distributing bandwidth among different video content types obviously does not satisfy the viewer's preferences well
[0010] When receiving multiple bitstreams, although the system can arbitrarily select a video bitstream to adjust to optimize its bandwidth usage, doing so may result in suboptimal performance or an unpleasant viewing experience for the user

Embodiment Construction

[0024] As described in this specification, the present invention provides an apparatus and associated method for receiving compressed video content and adjusting the compression ratio of the content in response to the available bandwidth of a network or part of the network, such as a network node or network gateway device. Recognizing that many existing media delivery formats lack support for this feature, this disclosure further describes advanced modifications that facilitate implementation of this functionality in adaptive streaming applications.

[0025] In a network-based video streaming system, multiple video bit streams can share bandwidth at a certain network node, for example, a home gateway that enables multiple viewers in the same house to watch different streaming video programs at the same time. Network congestion may occur when the overall bit rate of the aggregated video bit streams exceeds the bandwidth capabilities of the network node. On the other hand, when ...

Abstract

A method and apparatus for adaptively streaming multiple video bit streams through a network node is disclosed. In particular, a system is taught where at least one of the video bit streams is scaled in response to a bandwidth limitation or availability, where the selection of the bit stream selected for scaling in made in response to at least one of a user defined, service provider defined, and usage analysis defined priority list.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and all benefit of U.S. Provisional Patent Application Serial No. 61 / 310975, filed March 5, 2010, with the United States Patent and Trademark Office. technical field [0003] The invention relates to a method and equipment for adaptive streaming transmission of multiple video bit streams through network nodes. The device may be in the form of a set-top box for use with multiple television displays or other viewing devices. More specifically, the present invention relates to methods and devices for adaptive streaming of multiple video bitstreams through network nodes. In particular, the present invention teaches a system in which at least one video bitstream is scaled in response to bandwidth constraints or availability, wherein in response to user-defined, service provider-defined and usage analysis-defined priority lists, Select bitstream selection for scaling.
