Upload bandwidth to a remote device may vary depending on the location of a device transmitting information to the remote device. Location of an image capture device may be used to dynamically change the upload speed from the image capture device to the remote device.

A receiving side is enabled to perform excellent decode processing according to decoding capability. An image encoding unit classifies image data of each picture consisting moving picture data into a plurality of layers, encodes the classified image data of the picture in each of the plurality of layers, and generates video data having the encoded image data of the picture in each of the plurality of layers A data transmission unit transmits the video data. An information transmission unit transmits a level designation value of a bit stream and information on a layer range in each of a plurality of layer ranges having a different maximum layer.

The present application discloses a game picture display method and apparatus and a computer-readable storage medium. The method includes: displaying a picture in a target game in a client of the target game in a first display mode in response to that the client runs the target game, the client being installed on a mobile device; acquiring first state information of the mobile device; and switching a display mode of the client from the first display mode to a second display mode in a case that the first state information does not match the first display mode, and continuing to display the picture in the target game in the client in the second display mode, the target game in the client being kept in a running state in a process of switching the display mode. The present application solves the technical problem that a game cannot run smoothly in the related art.

Systems and methods are disclosed herein for presenting subtitle data during media asset fast-access playback operations. Specifically, the system may detect initiation of a fast-access playback operation during playback of a media asset and identify consecutive frames to be displayed during the fast-access playback operation that have associated subtitle data. The system may combine the subtitle data associated with the consecutive frames into a display arrangement and generate for display, with each consecutive frame, instead of the associated subtitle data, the display arrangement.

A video-processing method includes: obtaining a video frame rate of received video data; determining whether the video frame rate is less than the refreshing frame rate of a screen; and if yes, modifying at least one of the video frame rate of the video data or the refreshing frequency, so that the video frame rate of the video data is greater than or equal to the refreshing frame rate after modification. According to the present application, the effect that the video frame rate of a video file is greater than or equal to the refreshing frequency of the screen can be guaranteed, thus images corresponding to the video file can be displayed when the screen is refreshed, thereby avoiding standstill phenomena of video playback.

Provided is a video processing method, electronic device and computer-readable medium, relating to the technical field of video processing. A target frame of a video file is acquired by a central processing unit. a target area in the target frame is determined by the central processing unit. First image data corresponding to the target area is sent to a graphics processing unit, and the graphics processing unit is instructed to perform video enhancement processing on the first image data. Second image data corresponding to an area in the target frame except the target area is combined with the video-enhanced first image data to form an image to-be-displayed.

A data processing method and apparatus, and an electronic device, a system and a storage medium are provided. The method is applicable to a main thread in a Web client and includes: obtaining audio and video data of a target video from a server decapsulating the obtained audio and video data to obtain first audio and video data; sending the first audio and video data to a target sub-thread in the Web client, so that the target sub-thread decodes the first audio and video data to obtain second audio and video data and sends the second audio and video data to the main thread; receiving the second audio and video data sent by the target sub-thread; and rendering video data in the second audio and video data by using a rendering module of a browser of the Web client, and taking the rendered video data and audio data in the second audio and video data as to-be-played data for the target video. The technical solution according to the embodiment of the present application allows a Web client to play audio and video data without browser plug-ins.

One embodiment of the present invention is a method for playing a portion of a media work which includes steps of: (a) playing the media work; (b) receiving input from a user; (c) analyzing parameters to determine the portion of the media work to play; (d) altering at least a part of the portion; and (e) playing the portion.

One configuration as discussed herein includes a data processor acting as streaming server for providing streaming media from a repository to a decoder. The data processor retrieves reconstruction data and corresponding stream metadata from a repository, the reconstruction data encoded in accordance with a tiered hierarchy including multiple levels of quality. The data processor transmits selected portions of the reconstruction data to one or more decoder resources. The decoder resources reconstruct renditions of portions of a signal such as images/frames based on the transmitted portions of reconstruction data. During the transmission step, the data processor may vary a level of quality of the reconstruction data retrieved and transmitted to the decoder resource. Also, at times the data processor may transmit the levels of quality of the reconstruction data out of the natural sequence of the portions of the signal that they allow to reconstruct, anticipating or postponing the transmission of certain levels of quality of reconstruction data related to specific portions of the signal. The decoder resources decode the received reconstruction data to play back the signal at different levels of quality.

In the case where image data of a super-high definition service is transmitted without scalable coding, image data suitable to own display capability in a receiver not supporting the super-high definition service can be easily obtained.

A container in a predetermined format having a video stream including encoded image data is transmitted. Auxiliary information for downscaling a spatial and/or temporal resolution of the image data is inserted into the video stream. For example, the auxiliary information indicates a limit of accuracy for a motion vector included in the encoded image data. Further, for example, the auxiliary information identifies a picture to be selected at the time of downscaling the temporal resolution at a predetermined ratio.
