A signal transmitting method, a signal transmitting apparatus, and a signal receiving method, and a signal receiving apparatus are discussed, The signal transmitting method according to an embodiment includes encoding ultra high definition (UHD) video data; and encoding signaling information. A service type indicates a UHD digital television service using high efficiency video coding (HEVC). The signaling information includes linkage information. When a linkage type has one of specific values, the linkage type indicates additional linkage information. The UHD digital television service is signaled based on a link type and the linkage type. When a first value of the linkage type is used, an existing service is linked to a target UHD digital television service. When a second value of the linkage type is used, a UHD digital television service is linked to an existing service including a high definition or 3D service.

Disclosed herein are system, method, and computer program product embodiments for the automatic display of closed captioning information. An embodiment operates by accessing user behavior information for a program. It is determined, based on the user behavior information, that multiple closed captioning requests overlap during a portion of the program. A start time indicating when to begin and an end time indicating when to end display of closed captioning information for the overlapping portion is calculated. The program including the start time and the end time corresponding to the overlapping portion is provided for playback, wherein during a playback of the program, the closed captioning information is automatically displayed between the start time and the end time.

A computer-implemented method includes receiving a video frame. The computer-implemented method further includes dividing the video frame into two or more frame regions, each of the two or more frame regions corresponding to a selectively coolable region of a display. The computer-implemented method further includes identifying one or more frame characteristics for each of the two or more frame regions. The computer-implemented method further includes determining a cooling intensity to be applied to each selectively coolable region for displaying the video frame on the display based on the one or more frame characteristics. The computer-implemented method further includes applying the cooling intensity to each selectively coolable region at an effective time before displaying the video frame on the display. A corresponding computer system and computer program product are also disclosed.

A processing system includes a transport stream aggregator that receives a plurality of transport streams in a transport stream format and that generates an aggregated transport stream in response. The transport stream aggregator processes transport stream packets of the plurality of transport streams and replaces a packet synchronization field with a customized synchronization field. A processing device is configured to generate a processed video signal from the aggregated transport stream.

A method for transmitting device indicator data in a network-based AV system is provided. The method for transmitting the device indicator data records device indicator data on a data unit which is used in an AV transmission protocol, and transmits the data unit. Accordingly, the indicator data which changes in real time in a network AV device can be rapidly transmitted to a management platform.
