Transmission method, reception method, transmission apparatus, and reception apparatus

A transmission method includes generating one or more frames for content transfer using IP (Internet Protocol) packets, and transmitting the one or more generated frames by broadcast. Each of the one or more frames contains a plurality of second transfer units, each of the plurality of second transfer units contains one or more first transfer units, and each of the one or more first transfer units contains at least one of the IP packets. An object IP packet of the IP packets which is stored in a first transfer unit positioned at a head in the one or more frames contains reference clock information that indicates time for reproduction of the content in data structure different from data structure of an MMT (MPEG Media Transport) packet, and header compression processing on the object IP packet is omitted.

Publishing a disparate live media output stream manifest that includes one or more media segments corresponding to key events

A system is provided for publishing a disparate live media output stream manifest that includes media segments corresponding to key events. A live production and playout system of disparate sub-systems is synchronized to a reference clock. A timecode from the reference clock is used as a reference time to log content related to key events that occur within the live production and playout system. A live event logging system is synchronized to the reference clock same as the live production and playout system. Based on location of the live event logging system, a time offset is introduced to compensate for a delay. When delay is variable, the reference clock is decoded from a live input stream to associate each key event with a corresponding timecode. Based on a programming schedule comprising the key events that occurred in the live input stream, the disparate live media output stream manifest is published.

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.

Methods, systems, and computer readable media can be operable to facilitate the intercept and manipulation of content requested by a client device. The methods, systems, and apparatuses described herein enable the interception and redirection of packets based upon a set of rules. Intercepted packets may be redirected away from an origin server and may be forwarded to a splicing device. The splicing device may establish a session with a corresponding origin server, and retrieve content that is requested by the intercepted packet. In embodiments, the splicing device may identify alternate content that is associated with the intercepted packet and/or content that is further associated with a device or subscriber associated with the packet. One or more segments of the requested content, or the entirety of the requested content may be replaced with the alternate content, and the modified content may be output to the client device requesting the content.
