Problems solved by technology

However, this method is problematic when users want to view video immediately, especially on low-capacity links
Another problem is that in a changing wireless environment, adaptive downloads can suddenly drop to very slow speeds, causing pauses in the middle of the video

Embodiment Construction

[0031]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). As discussed in more detail below, some examples of the techniques of this disclosure include streaming video data that has been encapsulated in accordance with DASH via a file delivery service using a multicast or broadcast protocol, such as file delivery over a one-way transport (FLUTE) protocol. FLUTE is built on the Asynchronous Layered Coding (ALC) protocol that provides reliable delivery, and thus FLUTE may also be referred to as FLUTE / ALC. This disclosure describes various techniques that may be performed in conjunction with network streaming, any or all of which may be implemented alone or in any of various combinations. As described in more detail below, various devices that perform network streaming may be config...

Abstract

In one example, a device includes one or more processing units configured to send, via a network, a request to retrieve at least a portion of media content, wherein the media content conforms to dynamic adaptive streaming over HTTP (DASH), and wherein the request comprises a request that the at least portion be delivered according to a file delivery service, and, in response to the request, to receive streaming data for the at least portion of the media content in accordance with the file delivery service over the network. The device may prepopulate a browser cache with the received data, such that a browser can, in effect, stream data using the file delivery service. The device may initially retrieve data of the media content using unicast, until a switch point of the data received via the file delivery service is reached.

Description

[0001] This application claims the benefit of US Provisional Application No. 61 / 472,116, filed April 5, 2011, which is hereby incorporated by reference in its entirety. technical field [0002] This disclosure relates to the delivery of coded video data. Background technique [0003] Digital video capabilities can be incorporated into a wide variety of devices, including digital televisions, digital 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 similar devices. Digital video devices implement video compression techniques such as the standards defined by MPEG-2, MPEG-4, ITU-T H.263, ITU-T H.264 / MPEG-4 Part 10 Advanced Video Coding (AVC), and the The techniques described in extensions to these standards allow for more efficient transmi...
