Abstract

The present invention provides a system and method for sending and verifying URL signatures to access URL-addressable content in Adaptive Streaming. A plurality of URL authentication descriptors and URL authorization descriptors are provided for a plurality of URLs, wherein each URL authentication descriptor includes obtaining an authentication key and accessing an authentication tag to authenticate the plurality of URLs according to an associated URL authentication scheme Information for a given URL in . Each URL authorization descriptor is for obtaining an authentication key and an access authorization tag to authorize access to a given URL-addressable content of the plurality of URLs according to an associated URL authentication scheme. passing the plurality of URL authentication descriptors and URL authorization descriptors for the plurality of URLs, in the plurality of URL authentication descriptors and URL authorization descriptors passed, for each descriptor in the plurality of Given a URL among URLs, each descriptor is validated against its associated scheme.

Description

technical field [0001] The present invention is generally directed to uniform resource locator (uniform resource locator, URL) authentication, especially the application of URL authentication in URL-based content access authorization in adaptive flow. Background technique [0002] A media content provider or publisher can deliver a variety of media content to subscribers or users using different encoding schemes for different devices such as TVs, laptops, and mobile phones. A media content provider may support multiple media encoders and / or decoders (codecs), media players, video frame rates, spatial resolutions, bit rates, video formats, or combinations thereof. Media content can be converted from a source or original representation to various other representations for different user devices. [0003] Media content may include a media presentation description (media presentation description, MPD) and multiple fragments. The MPD may describe the media content, such as vari...
