Embodiment Construction

[0031] Example embodiments are described in detail below with reference to various drawings. While the present invention provides specific possible embodiments, it should be understood that these details are intended to be illustrative and not to limit the scope of the invention.

[0032] Figure 1A is an illustration of an example communication system 100 in which one or more disclosed embodiments may be implemented. Communication system 100 may be a multiple access system that provides content, such as voice, data, video, messaging, broadcast, etc., to multiple wireless users. The communication system 100 can enable multiple wireless users to access the content through the sharing of system resources (including wireless bandwidth). For example, communication system 100 may use one or more channel access methods such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), Single Carrie...

Abstract

Quality -based optimizations of a delivery process of streaming content may be enabled. The optimization may take the form of quality-based switching. To enable quality-based switching in a streaming client, the client may have access to information about the quality of an encoded segment and / or sub-segment. Quality-related information may include any number of added quality metrics relating to an encoded segment and / or sub-segment of an encoded video stream. The addition of quality-related information may be accomplished by including the quality-related information in a manifest file, including the quality-related information in segment indices stored in a segment index file, and / or providing additional files with quality- related segment information and providing a link to the information from an MPD file. Upon receiving the quality-related information, the client may request and receive a stream that has a lower bitrate, thereby saving bandwidth while retaining quality of the streaming content.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 669,983, filed July 10, 2012, and U.S. Provisional Patent Application No. 61 / 835,105, filed June 14, 2013, the contents of which are incorporated by reference in their entirety combined here. Background technique [0003] The MPEG / 3GPP Dynamic Adaptive HTTP Streaming (DASH) standard may define a framework for the design of bandwidth adaptive delivery of streaming content over wireless and wired networks. However, the MPEG / 3GPP DASH standard does not provide mechanisms for sensing and adapting to the complexity and quality of encoded video content. This results in certain inefficiencies in the use of network bandwidth resources and results in a sub-optimal user experience. Contents of the invention [0004] Systems, methods and means are disclosed that enable quality-based optimization of the delivery process for streaming content. The ...
