Broadcast receiving equipment

Abstract

To provide a technology for transmitting and receiving advanced digital broadcast services more appropriately.SOLUTION: A broadcast receiving device that can receive signals for each sound source via a broadcast wave, comprises: a broadcast receiving unit that receives the broadcast wave; a sound output unit configured by a plurality of loudspeakers to output sound according to the signals for each sound source that are transmitted from the broadcast receiving device; and a control unit. The control unit decides a sound reproduction position that depends on the signals for each sound source according to arrangement information on the plurality of loudspeakers, calculates a signal corresponding to a sound channel of 22.2 channels on the basis of the signals by sound source, and then, converts a signal corresponding to a sound channel for 22.2 channels into a signal for the sound output unit.SELECTED DRAWING: Figure 2A

Claims

1. A broadcast receiving device capable of receiving signals from different sound sources via broadcast waves, A broadcast receiving unit that receives the aforementioned broadcast waves, An audio output unit consisting of multiple speakers that outputs sound according to the sound source-specific signals transmitted from the broadcast receiving device, Control unit and Equipped with, The control unit, According to the arrangement information of the multiple speakers, the playback position of the sound based on the signal for each sound source is determined. Based on the aforementioned signals for each sound source, a signal corresponding to 22.2ch audio channels is calculated, and then the signal corresponding to the 22.2ch audio channels is converted into a signal for the audio output unit. The broadcast wave transmits to the broadcast receiving unit a parameter containing information on whether or not to allow the user to set the playback position for each signal from the sound source. The playback position setting is selected by the control unit from preset positions transmitted via the broadcast wave, or set by the user within a limited range. Broadcast receiving equipment.

2. In the broadcast receiving device according to claim 1, It further includes an operation input section for receiving control signals from a remote controller, The user can use the remote controller to set the playback position of the audio based on the signals for each sound source. Broadcast receiving equipment.

3. In the broadcast receiving device according to claim 1, It further includes a communication unit capable of receiving data via a network, The communication unit receives additional audio signals, different from the signals for each sound source, via the network. The control unit reproduces the sound from the audio signal together with the sound from the respective sound source signals received via the broadcast wave. Broadcast receiving equipment.

4. In the broadcast receiving device according to claim 1, When the broadcast receiving unit receives an emergency broadcast, the control unit disables the audio playback settings configured by the user and changes the audio playback settings to emergency broadcast settings. Broadcast receiving equipment.
