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.

A method, apparatus, and stored instructions are provided for selectively incorporating feedback from a remote audience into live content. The feedback is incorporated into one part of a segment at the same time that another part of the segment is played to an audience. A feedback manager may receive feedback from audience members on a first part of the segment while a second, later part of the segment is being played to the audience by a client machine and while a third, even later part of the segment is being generated by a content manager. The feedback manager may then compare feedback data to stored criteria to determine whether or not to change the playing content.

An association with a system timing at the time of transmission is secured without changing a display timing in text information of a subtitle, and a reception side displays the subtitle at an appropriate timing. A packet in which a document of the text information of the subtitle having display timing information is included in a payload is generated and transmitted in synchronization with a sample period. A header of the packet includes a time stamp on a first time axis indicating a start time of the corresponding sample period. The payload of the packet further includes reference time information of a second time axis regarding the display timing associated with the start time of the corresponding sample period.

A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system comprises a modulator configured to modulate one or more transmission symbols with signaling data for use in detecting and recovering the payload data at a receiver and to modulate one or more transmission symbols with the payload data. An emergency information receiver receives emergency information carrying information of an actual emergency. An emergency information embedder embeds emergency information into one or more transmission symbols, wherein the emergency information is embedded within a predetermined time period after its reception by using a resource used for carrying signaling data and/or payload data if no emergency information shall be transmitted. A transmission unit transmits the transmission symbols.

The present technology relates to an information processing device, an information processing method, a server device, and a program capable of presenting haptic information by using an existing data format.

A smartphone includes a data processing unit configured to supply a haptic control signal to a haptic presentation device on the basis of haptic control information embedded in image data in a predetermined file format. The present technology is applicable to, for example, a terminal device or the like including a display that displays an image and allows a user to perform a touch operation.

The present technology pertains to providing a live playback stream by a multi-media platform. During a live playback stream, the client device controls public playback of media items and is a source of live media during the live playback stream. The live playback stream can be made up of at least two streams between the client device and the multi-media platform. One stream is a playback control channel for transmitting data regarding playback controls pertaining to playback of recorded media content and another stream is a live media stream for transmitting data encoding live media. The multi-media platforms can transmit at least a portion of the data from the playback control channel and the live media stream to an audience member client device.

Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.

Embodiments for video processing, including video coding, video decoding and video transcoding are described. One example method includes performing a conversion between a video having one or more layers having one or more video pictures having one or more subpictures and a bitstream of the video according to a rule, wherein the rule defines network abstraction layer (NAL) units to be extracted from a bitstream during a sub-bitstream extraction process to output a sub-bitstream, wherein the rule further specifies that one or more inputs to the sub-bitstream extraction process include a target output layer set (OLS) index (targetOlsIdx) that identifies an OLS index of a target OLS and is equal to an index to a list of OLSs specified by a video parameter set, and wherein the one or more inputs satisfy a set of conditions.

Methods and systems for content modification are described. A computing device may determine a surface (e.g., a surface of an object) in primary content. The computing device may determine the surface is a candidate for placement of secondary content. The computing device may determine one or more output parameters associated with the surface. The computing device may adjust an output parameter of the one or more output parameters of the surface so as to optimize the surface for placement of the secondary content.

A method and system for dynamically watermarking media content based on transport-stream metadata, to facilitate action by a downstream entity. An intermediary in a media-distribution path could receive a transport stream carrying media content and carrying metadata that is not watermarked in the media content. The intermediary could then obtain from the transport stream the metadata that is not watermarked in the media content and could modify the media content at least by encoding into the media content a watermark that represents the obtained metadata. And the intermediary could then output at least the modified media content for transmission to a downstream entity. The downstream entity could thus obtain from the watermark in the media content the metadata and could use the metadata to facilitate carrying out one or more useful actions.
