Embodiment Construction

[0016] Systems, methods and media for providing alternative video using scalable video coding are provided. According to various embodiments, a scalable video coding (SVC) capable encoder may be provided with two or more video signals such that the encoder produces a base layer and one or more enhancement layers. The base layer can be used to provide base video content, and the enhancement layer(s) can be used to modify the base video content with enhanced video content. By controlling when enhancement layer(s) are available (eg, by hiding corresponding packets), the availability of enhanced video content to a video display can be controlled.

[0017] A scalable video protocol may include any video compression protocol that allows different representations of video to be decoded from data encoded using the protocol. Different representations of video may include different resolutions (spatial scalability), frame rates (temporal scalability), bit rates (SNR scalability), vario...

Abstract

Systems, methods, and media for providing selectable video using scalable video coding are provided. In some embodiments, systems for providing selectable video using scalable video coding are provided, the systems comprising: a scalable video coding capable encoder that receives a base content sequence and at least one added content sequence that has different content from the base content stream and that produces at least one SVC stream that includes a basic layer, that corresponds to the base content sequence, and at least one enhanced layer, that corresponds to content in the at least one added content sequence; and a digital processing device that controls whether the at least one enhanced layer in the SVC stream is displayed at a destination for the SVC stream.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application No. 12 / 170,674, filed July 10, 2008, the entire contents of which are hereby incorporated by reference. technical field [0003] The disclosed subject matter relates to systems, methods and media for providing selectable video using scalable video coding. Background technique [0004] Digital video systems have been used for a wide variety of purposes from entertainment to video conferencing. Many digital video systems need to provide different video signals to different receivers. This can be a rather complex process. [0005] For example, conventionally, when it is desired to provide different content to different recipients, a separate video encoder needs to be provided to each recipient. In this way, the video for the user is encoded with the corresponding encoder with respect to the recipient. However, dedicated encoders for individual users can be p...
