Image data having ultra-high definition at a high frame rate is processed to obtain image data, having a basic format, from which an image having high definition at a basic frame rate is to be obtained, image rate, having a first enhancement format, from which an image having high definition at a high frame rate is to be obtained, image data, having a second enhancement format, from which an image having ultra-high definition at a basic frame rate is to be obtained, and image data, having a third enhancement format, from which an image having ultra-high definition at a high frame rate is to be obtained. A basic video stream containing an encoded image data of the image data having the basic format, and a predetermined number of enhancement video streams containing the encoded image data of the image data having the first, second, and third enhancement formats are produced.

The playback of video content upon a display is enhanced through the unobtrusive presentation of extrinsic data upon the same display. A video content feature is rendered on a display. A quantity of extrinsic data relevant to a current time in the video content feature is determined based at least in part on viewing history of a user. A graphical element presenting at least a portion of the extrinsic data is rendered on the display while the video content feature is also being rendered on the display.

A system described herein provides real-time wireless video delivery using a multi-channel communications link. A method of employing elements of the system includes generating a first set of video data and generating a second set of video data. Further, encoding the first set of video data such that the second set of video data is a higher resolution version of the first set of video data and the encoded first set of video data is to supplement the second set of video data in response to a data drop.

Embodiments of the present disclosure relate to the field of video processing field, and provide a method, an apparatus, a server, and a storage medium for generating videos. In some embodiments, webpage snapshot data is obtained in real time based on a preset web address; target webpage content is selected from the obtained webpage snapshot data; and the selected target webpage content is synthesized with a pre-obtained input video, to generate an output video including the target webpage content.

The present disclosure relates to a content supply device, a content supply method, a program, a terminal device, and a content supply system, which are capable of performing rapid zapping between channels. A content supply device according to an aspect of the present disclosure includes a first supply unit configured to generate a zapping stream by delimiting streaming data according to a timing and a duration in common with another channel and to supply the zapping stream to a reception side via a network, a second supply unit configured to generate a viewing stream by delimiting the streaming data according to a duration of an integer multiple of the duration of the zapping stream and to supply the viewing stream to the reception side via the network, and a metafile generating unit configured to generate a metafile that is for the reception side to receive the zapping stream and the viewing stream. The present disclosure can be applied to a system in which content is delivered in a streaming manner.

Reception processing of broadcast content, in transmission of which an IP system is employed, is performed. An SDPT, in a header extension part of which service identification information and an SDP are arranged, in an SSC is transmitted from a broadcasting station. On a reception side, it becomes possible to acquire an intended SDPT from signaling information SSC easily at high speed by performing section filtering processing with respect to a received transport stream. Then, it is possible to access a stream of an intended channel at high speed based on an IP address and a port number described in an SDP stored in a header extension part of the acquired SDPT.

A device for retrieving media data includes a memory configured to store media data of a media presentation; and one or more processors implemented in circuitry and configured to: retrieve a manifest file for the media presentation, the manifest file including data for an initialization set, the initialization set including initialization parameters for the full duration of the media presentation; initializing playback of the media data of the media presentation using the initialization set; retrieving the media data of the media presentation; and present the media data according to the initialized playback. For example, the initialization parameters may specify a maximum width or a maximum height of pictures of the media presentation or a maximum frame rate of the media presentation. Thus, the processors can process pictures of any size less than or equal to the maximum width/height, or media data equal to or less than the maximum frame rate.
