Power aware adaptation for a power aware video streaming system may be based on the complexity information conveyed in different ways. A complexity level of a data stream, such as a video data stream, may be selected as a function of a remaining battery power of a wireless transmit/receive unit (WTRU) and on a state set of a plurality of state sets that may be stored and/or managed by the WTRU. These state sets may correspond to, for example, different content sources and/or different complexity estimation algorithms and may be used to select the complexity level of the data stream. The data stream may then be received at the selected complexity level. The complexity level and/or a bitrate of the data stream may be adapted to accommodate, for example, the remaining battery power and/or other circumstances. The adapation may be customized according to the objectives of use cases.

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a

URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.

Concepts and technologies are disclosed herein for creating a manifest file at a time of creating recorded content. A video device can request media content from a content source and receive the media content requested. The media content can be received with metadata from the content source. The video device can record the media content to generate recorded content and create, during the recording of the media content, a manifest file that includes at least a portion of the metadata that is received from the content source. The video device can store the recorded content and the manifest file.

It is distinguished that, to achieve the purpose above, the game video recommendation service in this invention is provided through the following phases in presenting the service of recommending to a game user another user's' game video: (a) the phase where, based on the object information including 3D shape information of the characters, props and backgrounds constituting game videos, the script information is saved in the video server for form a video list for game play video rendering, which records data on the appearance and disappearance points of time of characters, props and backgrounds included in the above-mentioned object information as well as their movements according to time; (b) the phase where users' in-game failures are detected and sent by the above game device the server; (c) the phase where the video lists saved in the said server are searched and videos (failure videos) including the foresaid failure situations or success videos resolving such situations are extracted; (d) the phase where a message recommending the failure video or success video searched in the previous (c) process (recommendation message) is sent to the game device that has sent the corresponding failure situation; and (e) the phase where the recommendation message of the (d) process is displayed on the device.

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. Each of the periods may include one or more representations. The metadata may include information used to describe a relationship between the representations, and include information for terminals having different display bit depths.

The present disclosure provides methods and devices for image loading. The method includes generating a request message requesting downloading compressed texture data corresponding to a basic image; sending the request message to a server; receiving compression format data sent by the server according to the request message; and sending to a GPU the texture data contained in the compression format data. The present disclosure provides methods and devices for video playback. The method includes extracting webpage source code corresponding to a webpage address entered by a user; determining in the source code a video link address containing a preset protocol header; obtaining an address editing rule and a video player corresponding to the preset protocol header; according to the address editing rule, editing the information and the video link address in the source code into a video playback address containing a preset protocol header; and playing a video resource corresponding to the video playback address.
