The influence of a multipath noise and an adjacent interference noise on the quality of reception of a broadcast is indexed in accordance with a received electric field strength level, and a broadcast station which is a station selection target is searched for using this index value.

Ancillary information associated with one or more images embedded in a digital broadcast data stream may be accessed by a digital broadcast receiving device. The device may include a receiver unit, a processor, and a memory. The processor may execute program instructions to access the ancillary information. Control data may be associated with one or more visual components of one or more video images. The control data and images may be combined into a digital broadcast data stream. The device may receive the images and control data. The images may be presented on a display device. The receiving device may use the control data to present or store a perceptible indication that ancillary information is associated with the visual components in conjunction with presenting the images. The device may use the control data to present or store the ancillary information in response to an input signal.

A media entertainment system including one or more user interfaces that are configured to receive user metadata selections and for receiving user settings for plural media source presets, playback volume settings, time settings, plural alarm settings, and plural alarm volume level settings. Each alarm and associated media source may have its own user selectable specific volume level setting that controls the appliance audio output volume when an alarm is triggered.

A technique of transmitting or receiving an advanced digital broadcasting service more suitably is provided. As the means, a broadcast receiving apparatus for receiving a broadcasting wave, a 2K broadcasting service and a 4K broadcasting service being transmitted by the broadcasting wave, includes: a receiver configured to receive the broadcasting wave; a display; and a controller. The controller is configured to identify whether simultaneous broadcasting of a 2K broadcasting service and a 4K broadcasting service in the broadcasting wave is executed or not on a basis of control information, the control information being contained in the broadcasting wave received by the receiver. In a case where an EPG screen for the 2K broadcasting service and the 4K broadcasting service included in the broadcasting wave received by the receiver is to be displayed on the display, the controller is configured to change a display state in the EPG screen of program information on any one service of the 2K broadcasting service or the 4K broadcasting service at least included in the broadcasting wave in accordance with the identifying result.

A method of transmitting a broadcast signal includes encoding mobile data for FEC (Forward Error Correction); encoding signaling information for signaling the mobile data; allocating the encoded mobile data and signaling data into a transmission frame; and transmitting the broadcast signal including the transmission frame, wherein the transmission frame includes a service signaling table having service_type information identifying a type of a service of the mobile data and hidden information indicating whether the service of the mobile data is hidden or not.
