A computer-implemented method for transmitting video from a source to a plurality of video receivers is provided. The method comprises receiving video from a camera corresponding to a scene being imaged; transmitting the video as a plurality of video streams, each to one of the plurality of video receivers; receiving feedback information from each of the plurality of video receivers; performing an optimization operation to optimize each of the plurality of video streams being transmitted based on the feedback information; wherein each optimized video stream is optimized for a particular video receiver based on the feedback information received for that video receiver.

The present technology relates to a reception apparatus, a reception method, a transmission apparatus and a transmission method in which NRT service is provided in digital broadcasting using an IP transmission method. There is provided a reception apparatus including: a channel selection control unit that performs a channel selection control of channel-selecting digital broadcasting using the IP transmission method; an acquisition control unit that controls acquisition of an application delivered through broadcasting or communication in the digital broadcasting based on signaling information transmitted at a layer higher than an IP layer in a protocol layer of the IP transmission method; and an application execution unit that executes the application acquired. The present technology is applicable to a television receiver, for example.

A method for selecting a tile amongst a set of tiles associated with a multimedia content divided into a plurality of tile segments requested by a terminal is described. The multimedia content that is divided into a plurality of tile segments, includes obtaining a next position of a viewport of the terminal at the expiration of a current tile segment based on an estimation of a trajectory of the viewport; identifying one or several tiles amongst the set of tiles comprising at least the viewport at the next position; determining at least one processing parameter depending on at least the center of the identified tile and the next position of the viewport; and selecting an identified tile for which the determined processing parameter meets a selection criterion.

An elementary module of a workflow of a system for distributing audiovisual contents is disclosed. Content is received as a succession of segments which are distributed following a transmission of a request and are obtained by an application of a workflow to a portion of a content. The elementary module executes a processing operation of a predefined type of the workflow and comprises: a variable plurality of processing units available for executing the processing operation of the predefined type, the elementary module regularly obtaining information representing each processing unit added to or removed from the plurality, an allocation module able to manage allocations or disallocations of processing units of the plurality according to requests for first data received; and a load management module able to choose, for each request received, at least one processing unit among the processing units allocated for processing second data in order to obtain first data requested.

A display apparatus including a display unit, a control apparatus, and a method are provided. The display apparatus includes a controller is configured to obtain a status signal from the control apparatus, to select, based on the obtained status signal, a mode from among a user interface (UI) display limit mode and a UI display mode, wherein the UI display limit mode limits displaying a UI to control an output from the display apparatus on the display unit and the UI display mode does not limit displaying the UI on the display unit, and to operate the display unit in the selected mode.

Systems and methods are disclosed for delivering video content over a network such as the Internet. Videos are identified and pre-processed by a web service and then separated into a plurality of segments. Based on user interest, video segments may be pre-fetched and stored by a client associated with a user. Upon receiving a selection from a user to play a video, the first video segment may begin playing instantaneously from a local cache. While the first video segment plays, subsequent video segments are transmitted from the web service to the client, so that the subsequent video segments will be ready for viewing at the client when playback of the first video segment has finished.
