• during display of the video content received via the first network transceiver on the first display panel, based on the user operation input interface receiving, at a first point of time, a first user operation to display on the display apparatus the video content displayed on the first display panel, control the first network transceiver to transmit first information containing identification information identifying the video content displayed on the first display panel to the display apparatus, without transmitting the video content itself to the display apparatus, in order for the display apparatus to display on the display apparatus the same video content as the video content displayed on the first display panel at the first point of time;
• based on transmission of the first information via the first network transceiver, control the first display panel to display information, on the first display panel, for receiving a second user operation to operate the video content displayed on the display apparatus after the first point of time;
• during display of the information for receiving the second user operation on the first display panel, based on the user operation input interface receiving, at a second point of time, the second user operation to operate the video content displayed on the display apparatus, control the first network transceiver to transmit second information related to the second user operation to the display apparatus, by which the smartphone is caused to serve as a remote-control device which is configured to operate the video content being displayed on the display apparatus;
• during display of the video content on the display apparatus, based on the user operation input interface receiving, at a third point of time, a third user operation to display on the first display panel the video content displayed on the display apparatus, control the first network transceiver to transmit third information related to the third user operation to the display apparatus, by which the smartphone is caused to terminate serving as the remote-control device configured to operate the video content displayed on the display apparatus;
• and
• based on transmission of the third information via the first network transceiver, control the first display panel to display the same video content, without receiving the video content from the display apparatus, as the video content displayed on the display apparatus at the third point of time,
• wherein the display apparatus comprises:
• a digital broadcast receiver configured to receive a digital broadcast signal via a TV antenna;
• a signal separator configured to conduct demultiplexing of the digital broadcast signal into audio data and video data;
• a video processor configured to convert a format of the video data;
• an audio processor configured to convert a format of the audio data;
• a second network transceiver configured to communicate over the Internet and conduct communication with the smartphone;
• a remote-control receiver configured to receive a command from the remote controller which receives an operation input for a digital broadcast signal reception, the remote controller being different from the smartphone;
• a second display panel;
• and
• a second controller configured to control an operation mode of the display apparatus,
• wherein the second controller is configured to:
• control the operation mode of the display apparatus to a first operation mode in response to the operation input from the remote controller via the remote-control receiver, wherein
• in the first operation mode, the signal separator is configured to demultiplex the digital broadcast signal received by the digital broadcast receiver into audio data and video data, the video processor is configured to convert the format of the video data, and the second display panel is configured to display a first video content based on the converted video data;
