A channel conversion part () performs channel conversion on audio data of a plurality of channels so that the number of channels thereof is converted to an appropriate number of channels for which an acoustic effect can be verified or perceived by audience according to the volume level of reproduced sound, and audio is output only with a required number of channels. In addition, a frequency control part () for controlling the operating frequencies of switching regulators (-) of audio amplifiers (-) also performs frequency control according to the volume level of sound of each channel which performs an audio output.

Audio control method and audio control apparatus

Whether or not HDCP authentication is necessary is determined and managed for each device connected to an HDMI port. In selector control, when switching to an HDMI port to which is connected a video signal output apparatus that requires HDCP authentication, DDC access is turned off by setting an HPD signal to Low. Communication is then resumed after a predetermined amount of time has passed by setting the HPD signal to High and thereby turning the DDC access back on. When switching to an HDMI port to which is connected a video signal output apparatus that does not require HDCP authentication, the HPD signal is kept at High, and video and audio data is output without resuming the DDC access.

Video control apparatus and control method for video control apparatus

A lighting apparatus includes a plurality of light sources of which emissions of light are able to be controlled independently of one another, a control unit configured to control brightness of each light source, and a measurement unit configured to measure the brightness of each light source. In cases where the brightness of each light source is measured, the control unit carries out a first control which causes a measurement target light source to turn on and at the same time light sources other than the measurement target light source to turn off, and a second control which decreases the brightness of each of the light sources in a stepwise manner immediately before a turn-off period of time thereof, and which increases the brightness of each of the light sources in a stepwise manner immediately after the turn-off period of time.

Lighting apparatus, control method therefor and backlight apparatus

A stereoscopic image display apparatus capable of generating a cursor that moves according to user operation to allow stereoscopic view with a stereoscopic image including a set of images with parallax and capable of combining and displaying the cursor on the stereoscopic image acquires a parallax amount of the stereoscopic image at a location where the cursor is combined and displayed on the stereoscopic image and calculates a moving speed of the cursor. The stereoscopic image display apparatus determines whether the cursor is moving based on the calculated moving speed and generates the cursor including a certain predetermined value as the parallax amount of the cursor if it is determined that the cursor is moving. The stereoscopic image display apparatus generates the cursor by setting the parallax amount of the cursor to the parallax amount of the acquired stereoscopic image if it is determined that the cursor is not moving.

Stereoscopic image display apparatus and cursor display method

In case a video display apparatus is connected to a video output apparatus using communication means that disconnects an electrical connection in accordance with stop of power supply from the video output apparatus is operating in an operation mode where an output of video data is restarted after an output of video data is temporarily stopped, control is performed so that the electrical connection is not disconnected. In a state where in accordance with supply power from the video output apparatus, a control signal for establishing an electrical connection via the communication means is in an ON level, in case stop of the power supply is detected, if the video output apparatus is in an operation mode where an output of video data is restarted after an output of video data is temporarily stopped, control is performed so that the control signal is not changed to an OFF level.

When a video output apparatus () is connected, a video display apparatus () obtains information of content data stored in the video output apparatus (). Then, based on the obtained information, the video display apparatus () determines whether the content data is decodable with respect to itself. If it is not decodable, it requests the video output apparatus () to decode the content data before transferring the content data using a data transfer method specified. By doing this, an appropriate transfer protocol is selected automatically when transferring content data between the video display apparatus () and the video output apparatus ().

When an image processing apparatus capable of connecting to a digital camera is to perform image-correction processing on irreversible-compression encoded image data acquired from the digital camera, it is determined whether the image-correction processing can be executed by the connected digital camera. When the processing can be executed, it is confirmed whether or not RAW data that corresponds to the irreversible-compression encoded image data is present in the digital camera. If the corresponding RAW data is present in the digital camera, the digital camera is requested to execute the image-correction processing based on the RAW data. This makes it possible to suppress degradation in the image quality more than when directly correcting an irreversible-compression encoded image.
