Broadcast receiving apparatus and transmission method of digital broadcast modulation wave
A broadcast receiving apparatus is configured to include: a tuner configured to receive a transmission wave, information regarding an injection level being stored in the transmission wave; and a controller. The controller is configured to identify that a rescanning process is required by using the information regarding the injection level contained in the transmission wave received by the tuner, the rescanning process being a setting process for receiving broadcast by the tuner.
1 . A broadcast receiving apparatus comprising:
a tuner configured to receive a transmission wave, information regarding an injection level being stored in the transmission wave;
a remote control receiver configured to receive a signal from a remote controller; and
a controller configured to execute a rescanning process independently of the signal from the remote controller received by the remote control receiver, the rescanning process being a setting process for receiving broadcast by the tuner,
wherein the controller is configured to:
identify that the rescanning process is required by using the information regarding the injection level contained in the transmission wave received by the tuner; and
execute the rescanning process.
2 . The broadcast receiving apparatus according to claim 1 , wherein the information regarding the injection level is information based on variation of a difference of signal levels of a plurality of transmission waves having different signal levels, the plurality of transmission waves being transmitted at the same frequency.
3 . The broadcast receiving apparatus according to claim 1 ,
wherein in a process of identifying that the rescanning process, which is the setting process for receiving the broadcast by the tuner, is required, the controller is configured to confirm whether a 4K broadcasting service list has already been stored in the broadcast receiving apparatus or not, and use a result of the confirmation for the identification.
4 . The broadcast receiving apparatus according to claim 1 , wherein the information regarding the injection level, which is contained in the transmission wave received by the tuner, is stored in a memory or a storage at a time of an initial scan.
5 . The broadcast receiving apparatus according to claim 1 , wherein the rescanning process is executed after the tuner shifts to a standby state for a viewing process or a recording process.
