Embodiment Construction

[0017] figure 1 is a block diagram of an environment for one embodiment of a system and method for adjusting bandwidth between multiple media streams. Core network adaptation device 110 receives one or more digital source formatted media streams 115 for delivery to various subscribers. In this disclosure, the term "media stream" refers to a stream comprising video frames, audio frames, hypermedia, multimedia, or any combination thereof. Common encoding formats for the source formatted media stream 115 include MPEG-2, MPEG-4, and VC-1. In some environments, an encoded media stream represents a single program, containing video and audio streams multiplexed together into a single program transport stream (SPTS).

[0018] Source formatted media stream 115 may be provided from a variety of sources. exist figure 1 In the exemplary environment of , source formatted media stream 115E is provided by encoder 120 that encodes an analog signal from a source of media content, such as...

Abstract

Disclosed herein are systems and method for adjusting bitrate among multiple media streams delivered on a common subscriber connection. One such method comprises receiving information describing a maximum bitrate provisioned on the subscriber connection, and receiving a plurality of media streams. Each media stream utilizes a corresponding bitrate, and the plurality of media streams has a combined bitrate. The method also comprises adjusting the bitrate of at least a portion of the plurality of media streams so that the combined bitrate is related to the maximum bitrate provisioned on the subscriber connection.

Description

[0001] Cross References to Related Applications [0002] Not applicable. technical field [0003] The present disclosure relates to electronic devices, and more particularly to systems and methods for adjusting bandwidth between multiple media streams. Background technique [0004] An increasing number of consumers now have high-speed or broadband connections to the Internet in their homes. Generally, consumers receive Internet access services through this broadband connection, which enables one or more personal computers to access the World Wide Web and other Internet resources. In addition to this data service, the increased bandwidth provided by broadband connections enables providers to deliver other media services, such as telephony, digital television, to multimedia terminal adapters (MTA) or digital home communication terminals (DHCT) and / or video. [0005] These data and media services share the bandwidth of the subscriber's broadband connection. In the case of ...
