Abstract: By transmitting region reconstruction information from a network side device to a terminal side device, quality is enhanced in video reconstruction by super resolution techniques or the like. A video is divided into multiple regions, and the region reconstruction information includes video reconstruction information for each of the multiple regions divided. The region reconstruction information is generated based on the classification information associated with the video.

Abstract: The accuracy of a motion vector is switched based on a picture or a slice. An inter prediction parameter decoding control unit shifts a difference vector by using a shift amount that is identified by a flag for which a value range is configured based on a mode configured for a predetermined region of a reference image including a plurality of prediction blocks.

Abstract: A problem to be addressed by disclosure is, without using a specific device such as an eye-tracking device, to extract from a bird's-eye image a region of interest of a subject person as a region of interest image as viewed through the eyes of the subject person. Provided is a region of interest image generating device, which extracts, from at least one bird's-eye image, camera parameters, and spatial position information which includes information of the heights of objects in the at least one bird's-eye image, a region of interest in the at least one bird's-eye image as a region of interest image as viewed from a different viewpoint.

Abstract: With use of a PinP function, a display processing unit (230) of a display device (200) displays, while displaying a video of a baseball broadcasting program on a secondary screen positioned at a center part or its upper part of a primary screen, a different video, captured by a “camera including a wide-angle lens” that is installed behind the outfield of a baseball park as a broadcast spot, on the primary screen.

Abstract: In a remote simultaneous viewing system, zapping for a different group that views a content having the same attribute as that of a content viewed by a belonging group of a user is enabled. A content reproduction portion (22) that reproduces a content; and a group switching portion (25) that switches a belonging group of a user to a different group that views a content having the same attribute as that of the reproduced content are included.

Abstract: A group-viewing assistance device allowing a viewer to perform group-viewing without giving much resistance is realized. A group-viewing assistance server (100) presents a viewing environment list indicating, for each group, which content is under group-viewing, executes processing for causing a person who desires group-viewing to participate in remote communication in a group designated by the desiring person, and causes a viewing apparatus (200) of the desiring person to reproduce a content under group-viewing by the group.

Abstract: While executing a television viewing APP, an engine (112) performs another application. A degree-of-concentration determination unit (131) determines the frequency of operations for the application, and calculates the degree of concentration for the program on the basis of the type of the application and the determination result. When the degree of concentration is high, the presentation controller (140) displays an advertisement relevant to the program, on a display unit (150).

Abstract: A device (100) includes a reception unit (110) that receives a program accompanied by a main advertisement from a device (300), a processing unit (120) that displays a program image on a display unit (140), and an engine (131) that displays the main advertisement on the display unit (140). The engine (131) transmits control information indicating a method of controlling displaying a related-advertisement to a sub-device (200) that receives the related-advertisement related to the main advertisement from a server (400) and displays the received related-advertisement.

Abstract: A television set (10) capable of receiving a video content and an additional content including information associated with the video content includes a demultiplexing unit (12) configured to display the video content on a display unit (16) and the additional content on a tablet terminal (20).

Abstract: An image quality/rate control portion 106 confirms whether a predictive code amount Ci is a target code amount Rt or less. When the predictive code amount Ci is the target code amount Rt or less, the predictive code amount Ci is output to a base layer coding portion 101. Then, a switch 108 is turned off. When the predictive code amount Ci exceeds the target code amount Rt, the target code amount Rt is output to the base layer coding portion 101. Then, the switch 108 is turned on and (predictive code amount Ci?target code amount Rt) is output to an enhancement layer coding portion 103. A buffer 104 stores coded data of the base layer coding portion 101 and the enhancement layer coding portion 103. In this manner, while performing fixed bit rate coding using a single transmission path, image quality of a moving image is made constant so as to prevent deterioration of image quality.

Abstract: A control information decoding section (102) decodes sets of control information contained in a stream. Further, a random access information analyzing section (101) carries out analysis of locations of random access points of media items contained in the stream, on the basis of the sets of control information. Still further, a management information generating section (103) generates management information for managing a plurality of random access points contained in the stream, on the basis of decoded versions of the sets of control information, which has been obtained by the control information decoding section (102), and the locations of the random access points obtained by the analysis performed by the random access information analyzing section (101). Then, the management information thus generated and the stream are recorded onto a storage medium (104).
