A display controlling method for a broadcast receiving apparatus allowed to receive IP simultaneous broadcasting of a 4K broadcasting service via a communication transmission line, in which simultaneous broadcasting of the 4K broadcasting service and a 2K broadcasting service is executed by a broadcasting wave, is configured to: receive and demodulate the 4K broadcasting service, and display a broadcasting program of the 4K broadcasting service; and select and execute one display switching process of first and second display switching processes in accordance with priority order in a case where a defect occurs in reception, demodulation, or display of the 4K broadcasting service, the 2K broadcasting service being received and demodulated to display a broadcasting program of the 2K broadcasting service in the first display switching process, the IP simultaneous broadcasting being received and demodulated to display a program of the IP simultaneous broadcasting in the second display switching process.

Described is a method of audio processing in a HbbTV terminal device. The method includes receiving a decoded broadcast feed including a first audio track, receiving HbbTV content relating to the broadcast feed, the HbbTV content including a second audio track, extracting level-related information from the decoded broadcast feed, wherein the level-related information is embedded in the decoded broadcast feed and enables to obtain an indication of an original audio level of the first audio track, analyzing the first audio track for determining an actual audio level of the first audio track, determining a gain factor based on the actual audio level and the original audio level, and generating a third audio track for output by the HbbTV terminal device based on the first audio track, the second audio track, and the gain factor. Also described is an apparatus for carrying out the method, as well as corresponding programs and computer-readable storage media.

Methods and systems of managing advertising content are shown and disclosed. In one embodiment, the method includes outputting first multimedia content from a first channel, and outputting TAD content from a TAD channel instead of the first multimedia content during a TAD window of the first multimedia content. The method additionally includes receiving a first user input requesting multimedia content of a content channel different from the TAD channel during the TAD window, and outputting the multimedia content of the content channel instead of the TAD content in response to the first user input.

The present invention relates to a device for receiving a hybrid broadcast service and a method for transmitting the same. The device for receiving a hybrid broadcast service, according to one embodiment of the present invention, comprises: a first reception unit for receiving a first broadcast signal transmitted through a first network; a second reception unit for receiving a second broadcast signal transmitted through a second network, wherein the broadcast signal includes a service information table; a signaling information processing unit for extracting the service information table from the broadcast signal, wherein the service information table includes a component identifier descriptor for signaling information for identifying each of a plurality of components constituting one broadcast service, the component identifier descriptor including identification information; and an audio/video processing unit for acquiring the broadcast service including the plurality of components by using the component identification information, and decoding and reproducing the acquired broadcast service.

There is provided a receiver device including a first input terminal, a second input terminal, a first distribution circuit, a second distribution circuit, a first high-frequency processing unit, and a second high-frequency processing unit.

A video processing apparatus includes a down-sampling circuit, a combining circuit, a metadata generating circuit, and an encoder. The down-sampling circuit down-samples P videos according to predetermined picture layout information of K picture layouts. Each of the videos corresponds to a television program. The combining circuit combines the P down-sampled videos according to the predetermined picture layout information to generate combined videos corresponding to the K picture layouts. The metadata generating circuit generates metadata that describes television program information corresponding to the picture layouts according to the predetermined picture layout information. The encoder encodes the combined videos and the metadata to image data that conforms to a predetermined broadcast format for a television broadcasting system to broadcast.

A display apparatus includes a display configured to display an image based on at least one between received first and second broadcast signals, a first signal processor configured to selectively activate and inactivate an operation for processing the first broadcast signal, a second signal processor configured to selectively activate and inactivate an operation for processing the second broadcast signal, and a controller configured to control the first signal processor and the second signal processor to selectively activate or inactivate the operations for processing the first broadcast signal and the second broadcast signal in response to a command for switching between the first broadcast signal and the second broadcast signal.

Disclosed is a broadcast receiving device. A terrestrial broadcast receiving unit receives a terrestrial broadcasting service. A mobile receiving unit receives a mobile broadcasting service transmitted via a network for mobile communication. A control unit allows the terrestrial broadcasting service and the mobile broadcasting service to be selectively received.

A display apparatus includes a display configured to display an image based on at least one between received first and second broadcast signals, a first signal processor configured to selectively activate and inactivate an operation for processing the first broadcast signal, a second signal processor configured to selectively activate and inactivate an operation for processing the second broadcast signal, and a controller configured to control the first signal processor and the second signal processor to selectively activate or inactivate the operations for processing the first broadcast signal and the second broadcast signal in response to a command for switching between the first broadcast signal and the second broadcast signal.
