摘要： 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.

摘要： Changes to the functions of an apparatus and the addition of appliances can be easily performed without needing to change the internal wiring or make connections with signal cables. The system includes a first signal processing means (151, 152) that process an input signal, a judging means for judging whether an expansion second signal processing means (160) is present, a communication means for performing data transfers between the first signal processing means and the expansion second signal processing means via wireless communication, and a control means (171) that changes, when the judging means has judged that an expansion second signal processing means is present, the processing function for an input signal by having wireless communication executed by the communication means. Also, data transfers inside the first signal processing means and the second signal processing means may be performed via wireless communication as necessary.

摘要： Practical speaker connection is identified using a device having a sound channel of a 5.1 channel or 7.1 channel, and a device is provided that can easily reproduce the optimum multiple channels. Actual speaker arrangement can be identified by, for example, measuring the impedance of a terminal at the side of an audio amplifier. If incorrect connection is found, a warning is issued. This information is transmitted to a signal source with an EDID and a signal with the optimum a number of sound channel is sent. The EDID is also used for the connection with a display unit and the speaker connection with which the display unit is provided uniquely. For example, a sound through the 7.1 channel is easily reproduced using the speaker of the display unit in the channel of the front speaker.

摘要： PROBLEM TO BE SOLVED: To generate a sound suitable for a display region of an animation on a display screen when playing back the animation. SOLUTION: An image transformation information supply section 130 calculates, for each frame, an affine transformation parameter for transforming an image based on motion information of an animation. An image transforming section 140 uses the calculated affine transformation parameter, with a reference image as a criterion, to perform affine transformation, for each frame, upon an image constituting the animation. A sound conversion information calculating section 190 calculates sound conversion information for converting a sound corresponding to the transformed image from the image transforming section 140 based on information indicating a central position, angle or magnification of the image. A sound conversion processing section 200 adjusts the volume of channels constituting the sound based on the sound conversion information, adds the adjusted sounds of the channels and outputs the results to a speaker 220 as an output sound.
