A broadcast receiving device for receiving a transmitted service by using an MPEG Media Transport (MMT) protocol includes a tuner configured to receive Service Layer Signaling (SLS); a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory to obtain information of one or more contents constituting the service, from an MMT Package (MP) table included in the SLS, determine whether there is second content that is the same as first content being currently received through a first transfer path and is received through a different transfer path from a transfer path of the first content, among the one or more contents, based on the information of the one or more contents, and perform, when there is the second content, a handoff of a content receiving channel from the first transfer path to a second transfer path corresponding to the second content to receive the second content.

The present invention relates to a method for transmitting and receiving program configuration information for a scalable ultra high definition (UHD) video service under the hybrid transmission environment, and to a method and apparatus for effectively transmitting scalar layer information, and more particularly, the present invention relates to a scheme for inserting group information for the scalable layer of a base layer and an enhancement layer, which form a scalable UHD video, and transmission channel information into a program map table (PMT) or a package configuration table (PCT), and for transmitting same, and to a scalable layer information format for transmitting layer information with a smaller number of bits as possible when a packet header includes scalable layer information.

A device for determining information for video data includes one or more processors implemented in circuitry that are configured to determine one or more most-interested regions of a plurality of regions of an image of video data from data representative of the one or more most-interested regions. The one or more processors are further configured to generate a request specifying the one or more most-interested regions using the data representative of the one or more most-interested regions and output the request to a server device.

In an example method, a system receives a plurality of frames of a video, and generates a data structure representing the video and representing a plurality of temporal layers. Generating the data structure includes: (i) determining a plurality of quality levels for presenting the video, where each of the quality levels corresponds to a different respective sampling period for sampling the frames of the video, (ii) assigning, based on the sampling periods, each of the frames to a respective one of the temporal layers of the data structure, and (iii) indicating, in the data structure, one or more relationships between (a) at least one the frames assigned to at least one of the temporal layers of the data structure, and (b) at least another one of the frames assigned to at least another one of the temporal layers of the data structure. Further, the system outputs the data structure.

In a picture processing method, when receiving a first picture in a video stream, a decoder side determines, based on a base layer of the 1st sub-picture of the first picture, whether the first picture meets a first preset condition; and the decoder side sends a second picture within a display time period of the first picture for displaying if the first picture meets the first preset condition, where the second picture is a picture that is in the video stream and that is sent within a first display time period for displaying.

A video decoder chipset (200, 300, 400, 500) comprises a video decoder function (210), an upscaler function (230) and a combiner function (240). The video decoder function (210) is configured to (i) decode encoded video data to generate decoded video data at a first level of quality, the encoded video data having been derived by an encoder using first video data at a second, higher level of quality and (ii) output the decoded video data for storage in a memory (220). The upscaler function (230) is configured to (i) obtain the decoded video data from the memory (220) and (ii) upscale the obtained decoded video data to generate second video data at the second level of quality. The combiner function (240) is configured to (i) obtain residual data, the residual data having been derived by the encoder based on the first video data and the second video data, (ii) combine the second video data with the residual data to generate enhanced video data, and (iii) output the enhanced video data.

An adaptive action recognizer for video that performs multiscale spatiotemporal decomposition of video to generate lower complexity video. The adaptive action recognizer has a number of processing pathways, one for each level of video complexity with each processing pathway having a different computational cost. The adaptive action recognizer applies a decision making scheme that encourages using low average computational costs while retaining high accuracy.
