A process for operating an electronic computing device to assign video streams to watcher devices. The electronic computing device detects objects of interest within a field-of-view of a camera as a function of incident context information. The electronic computing device obtains video display characteristics associated with watcher devices and further determines, based on respective positions of the objects of interest within the field-of-view, a plurality of sub-regions each enclosing at least one of the detected objects of interest and having one or more video attributes. The electronic computing device then assigns, based on the video display characteristics associated with the watcher devices and the video attributes of the sub-regions, each of the sub-regions to a respectively selected one of the watcher devices. The video streams respectively captured corresponding to each of the assigned sub-regions of interest are then transmitted to the respectively selected one of the watcher devices.

A system that handles delivery of service(s) through a client device, includes an interactive service provider, a video service provider, and a client device. The interactive service provider inserts at least one of digital watermarks and digital fingerprints in non-programming media content. The video service provider transmits a media stream of the media content that includes programming media content and the non-programming media content. The client device detects at least one of the inserted digital watermarks and the digital fingerprints in the playback duration of the media content and renders overlay graphics on the media content. The client device activates at least one of input devices paired with the client device and the rendered overlay graphics. The client device further receives trigger responses over activated overlay graphics and displays an interactive view to enable delivery of service(s) in response to the trigger responses.

Systems, apparatuses, and methods are described for a user device controlling a playback buffer to reduce latency in a service change.

A method and apparatus generate and process transport packets. A method of processing a transport packet at receiving entity includes identifying, in response to receiving the transport packet, a payload type based on a field indicating the payload type in a packet header for the transport packet. The method also includes identifying, in response to identifying that the payload type is a streaming mode payload type, a delivery data unit type of DU data in the transport packet based on a field indicating the delivery data unit type in a streaming mode payload header for the DU data. Additionally, the method includes processing the DU data according to the identified delivery data unit type.

A processing load at a receiving side is reduced in a case where a plurality of classes of audio data is transmitted. A predetermined number of audio streams including coded data of a plurality of groups is generated and a container of a predetermined format having this predetermined number of audio streams is transmitted. Command information for creating a command specifying a group to be decoded from among the plurality of groups is inserted into the container and/or the audio stream. For example, a command insertion area for the receiving side to insert a command for specifying a group to be decoded is provided in at least one audio stream among the predetermined number of audio streams.

A method of session-based DASH operations can include receiving a media presentation description (MPD) referencing a session-based description (SBD) and indicating a key name during a media access session. The SBD includes a first repeating pattern element that includes a first sequence of timed key values of the key name. The first repeating pattern element indicates that the first sequence of the timed key values of the key name is relocated along a timeline or an orderline. A first key value of the key name corresponding to a timing or a segment number of a current segment of a sequence of segments can be determined based on the first repeating pattern element in the SBD. A request for the current segment can be transmitted to a media content server. The request includes a pair of the key name and the first key value.
