Embodiment Construction

[0033] In general, this disclosure describes techniques related to the streaming of multimedia data, such as audio and video data, over a network. The techniques of this disclosure may be used in conjunction with Dynamic Adaptive Streaming over HTTP (DASH). This disclosure describes various techniques that may be performed in connection with network flows, any or all of which may be implemented individually or in any combination. As described in more detail below, various devices that perform network flows may be configured to implement the techniques of this disclosure.

[0034] According to DASH and similar technologies for streaming data over a network, multimedia content (such as movies or other media content, which may also include audio data, video data, text overlays or other data) can be encoded in a variety of ways and have multiple a characteristic. A content preparation device may form multiple representations of the same multimedia content. Each representation m...

Abstract

In one example, a device for receiving information of multimedia data includes one or more processors configured to: determine a file of a representation of multimedia content to be requested from a source device byte range; forming a Uniform Resource Locator URL specifying the file and byte range as required by the source device in the file path portion of the URL according to a template; and issuing a request to the source device specifying the formed URL GET requests.

Description

[0001] This application claims the benefit of US Provisional Application No. 61 / 473,105, filed April 7, 2011, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to storage and transmission of encoded multimedia data. Background technique [0003] Digital video capabilities can be incorporated into a wide range of devices including digital televisions, digital direct broadcast systems, wireless broadcast systems, personal digital assistants (PDAs), laptop or desktop computers, digital cameras, digital recording devices, digital Media players, video game devices, video game consoles, cellular or satellite radio phones, video teleconferencing devices, and the like. Digital video devices implementing video compression techniques such as those defined in MPEG-2, MPEG-4, ITU-T H.263 or ITU-T H.264 / MPEG-4 Part 10 (Advanced Video Coding (AVC)) standards and the techniques described in extensions to those standards) to t...
