A program map table in a transport stream comprising an elementary stream identifier indicating a particular elementary stream, a high dynamic range flag indicating the presence or absence of high dynamic range content within the elementary stream, and a wide color gamut flag indicating the presence or absence of wide color gamut content within the elementary stream.

Provided is a method of coding blocks of video data representing an image using an encoder, the method including identifying, by the encoder, a first region of the image and a second region of the image, a sum of a first number of pixels in the first region and a second number of pixels in the second region being equal to a total number of pixels of the image, and allocating, by the encoder, a first number of bits including base bits for encoding the first region, and a second number of bits including base bits and enhancement bits for encoding the second region, a sum of the first number of bits and the second number of bits being equal to a total number of bits for encoding all of the pixels, wherein the second region is encoded with a greater number of bits per pixel than the first region.

An image distribution apparatus includes an acquisition unit configured to acquire information about a gazing area specified by a user in a first image, and a transmission unit configured to transmit, from a second image having resolution higher than resolution of the first image and divided into a plurality of tile images, a first tile image where the gazing area belongs and a second tile image adjacent to the first tile image.

A video decoder may be configured to output layers of video data according to layers specified in an output layer set mode as well as based on the actual layers received in an access unit. Accordingly, the video coder may be configured to output layers actually received rather than restart a video bitstream in situations where the layers actually received do not match the layers specified in the output layer set mode. In another example, a video encoder may disable inter prediction when the sub-picture ID of a sub-picture in a currently coded picture does not match the sub-picture ID of a sub-picture in a reference picture.

One high-level aspect of a content-modification system and related methods may involve facilitating content modification by a content-presentation device of received broadcast content in a controlled manner, while under circumstances in which some events that can impact timing may be unpredictable. In particular, certain operations by a content-presentation device may involve matching received content with specific expected content as determined by one or another component of the content-modification system, in order to confirm proper conditions are met for the content-presentation device to proceed with, or continue, content-modification operations. It can happen the matching procedure becomes subject or susceptible to timing irregularities, or jitter. In some instances, jitter may impact the ability to derive the benefits of content modification. Accordingly, example embodiments herein are directed to systems and method for compensation and/or mitigating the effects of jitter.

An electronic device is provided. The electronic device includes a display, at least one processor, and at least one memory configured to store instructions that cause the at least one processor to obtain first information from a first still image frame that is included in a first moving image, obtain second information from the first moving image, identify at least one image function based on at least one of the first information or the second information, and control the display to display at least one function execution object for executing the at least one image function. Various other embodiments can be provided.

An apparatus and method for transmitting and receiving information related to multimedia data in a hybrid network and a structure thereof are provided. The transmission method includes generating transmission characteristic information about the media data, and transmitting the transmission characteristic information. The transmission characteristic information includes valid range information about the transmission characteristic information.

The present technology makes it easy to present an image having appropriate image quality at a receiver side that receives high-frame-rate moving image data. A video stream obtained by encoding moving image data having a high frame rate is generated. A container containing the video stream is transmitted. Blur control information for controlling blur is inserted into a layer of the container and/or a layer of the video stream. The blur control information gives, for example, weighting coefficients for individual frames in a blurring process for adding image data of neighboring frames to image data of a current frame.

The present disclosure relates to an information processing apparatus and an information processing method that enable processing to be performed simply, and a program. By converting a point cloud representing a three-dimensional structure into two dimensions, a geometry image and a texture image, and three-dimensional information metadata required for constructing the geometry image and the texture image in three dimensions are obtained. Then, one PC sample included in a Point Cloud displayed at a specific time is generated by storing the geometry image, the texture image, and the three-dimensional information metadata in accordance with a playback order required at a time of reproducing and playing back the geometry image and the texture image in three dimensions on the basis of the three-dimensional information metadata. It is possible to apply to a data generation device that generates data for distribution of a Point Cloud.
