Both a conventional receiver and an HDR-compatible receiver well perform electro-optical conversion processing on transmission video data obtained by using an HDR opto-electronic transfer characteristic. High dynamic range opto-electronic conversion is performed on high dynamic range video data to obtain the transmission video data. Encoding processing is performed on this transmission video data to obtain a video stream. A container of a predetermined format including this video stream is transmitted. Metadata information indicating a standard dynamic range opto-electronic transfer characteristic is inserted into a layer of the video stream, and metadata information indicating a high dynamic range opto-electronic transfer characteristic is inserted into at least one of the layer of the video stream and a layer of the container.

Concepts and technologies are disclosed herein for providing streaming video from mobile computing nodes. A request for streaming video captured by a mobile computing node can be received at a computer including a processor that executes a controller. The request can include a parameter associated with the streaming video. The computer can initiate transmission of an inquiry message to two or more mobile computing nodes and receive inquiry message responses from the mobile computing nodes that include the mobile computing node. The inquiry message responses can indicate that the mobile computing nodes can satisfy the parameter. The computer can create a list of the mobile computing nodes that can satisfy the parameter and provide the list to the requestor. The computer can receive a selection of the mobile computing node, and initiate delivery of a video stream to the requestor.

A distribution device for delivering a selected viewport stream of virtual reality (VR) data to each of a plurality of client devices, comprising a processor configured for receiving a plurality of extended viewport streams of a VR video file each comprising a sequence of extended field of view (EFOV) frames created for a respective one of a plurality of overlapping segments constituting a sphere defined in the VR video file and delivering a selected one of the plurality of extended viewport streams to each of a plurality of client devices by performing the following for each of the client devices in each of a plurality of iterations: (1) receiving a current orientation data of the respective client device; (2) selecting one of the plurality of extended viewport streams according to the current orientation data; and (3) transmitting the selected extended viewport stream to the respective client device.

A method for streamed playback of media in a media client from a remote media service includes: a) determining address information for locating the service and for a starting time; b) by the address information, requesting and receiving a first media package from the service; the package having decoder configuration information, one or more frames, associated timing information for playback frames, and a pointer to a subsequent part of the media stream; c) configuring a decoder of the client by the decoder information; d) starting playback of the stream in the client at the starting time by providing the frames to the configured decoder; e) by the pointer, requesting a remaining portion of the media having subsequent frames of the media stream and associated timing information; f) receiving the subsequent frames as a stream and continuing playback by providing the subsequent frames and associated timing information to the configured decoder.

The present application discloses techniques for playback of live broadcast content. The techniques comprise receiving a request of playing live broadcast content from a client computing device, wherein the request comprises information indicating a first address associated with the live broadcast content, and the request further comprises a playback time parameter indicating a playback time length; generating a second address based on a current system time parameter, the first address, and the playback time parameter; obtaining live broadcast content based on the second address and transmitting the live broadcast content to the client computing device.

A computer implemented method that includes receiving first user usage data and second user usage data indicative of user usage during consumption of a first content and of a second content, respectively. The method includes determining a first user usage pattern for the first content and a second user usage pattern for the second content based on the first user usage data and on the second user usage data, respectively. The method determines potential content overlap between the first content and the second content based on a comparison of the first usage pattern and the second usage pattern and performs an optimization operation based on the potential content overlap.
