    • A CPU in a home theater device transmits current sound volume control status data to a digital television receiving device when a theater mode is set. A CPU in the digital television receiving device updates, when the sound volume control status data has been received from the home theater device, sound volume control status data stored in a memory with the received sound volume control status data. A CPU in the digital television receiving device determines sound volume setting value data after an operation based on sound volume operation information fed from a remote control device and the sound volume control status data stored in the memory, and transmits a CEC command including the determined sound volume setting value data to the home theater device while displaying a ratio of the current sound volume to a maximum value in a sound volume adjustable range of the home theater device on a display.
    • 当设置剧院模式时,家庭影院设备中的CPU将当前音量控制状态数据发送到数字电视接收设备。 当已经从家庭影院设备接收到音量控制状态数据时,数字电视接收设备中的CPU更新存储在具有接收到的音量控制状态数据的存储器中的音量控制状态数据。 数字电视接收装置中的CPU基于从遥控装置馈送的音量操作信息和存储在存储器中的音量控制状态数据进行操作之后的音量设定值数据,并发送包括确定的声音的CEC命令 将家庭影院设备的音量设定值数据显示在家庭影院设备的音量调节范围内,同时显示当前音量与最大值的比例。
