To enable HDR video signals of a plurality of signal interfaces to be satisfactorily handled. [Solution] A processing unit processes a linear high dynamic range video signal and obtains a high dynamic range video signal that has undergone a grayscale compression process. The processing unit is able to perform grayscale compression processes of a plurality of signal interfaces. For example, when a grayscale compression process of another signal interface other than a reference signal interface is performed, the processing unit further performs a process of adding characteristics of system gamma of the reference signal interface and a process of cancelling out characteristics of system gamma of the other signal interface.

An information processing apparatus includes the following elements. A generation unit generates a multiplexed video frame having a predetermined screen size. A dividing unit divides input audio data into audio data items each having samples for one frame period of the multiplexed video frame. A multiplexing unit multiplexes audio data items obtained by dividing each stream of input audio data and number-of-samples information representing the number of samples thereof. A processing unit processes audio data items multiplexed in a multiplexed video frame input from an input video port, and outputs from an output video port thereof a multiplexed video frame in which the resulting audio data items and the number-of-samples information thereof are multiplexed. An extraction unit extracts the audio data items multiplexed in the multiplexed video frame output from the processing unit in accordance with the number-of-samples information. A transmission unit outputs the extracted audio data items to outside.

An information processing device includes: a clipping unit configured to subject a plurality of images to clipping processing for clipping a part of an image as a partial image to clip a partial image from each of the plurality of images; a size correcting unit configured to correct an image size regarding each of a plurality of the partial images clipped by the clipping unit; and a synthesizing unit configured to connect the partial images of which the image sizes have been corrected by the size correcting unit to generate a synthetic image.

Information processing device and method, and program

A communication device includes a transmission amplifier supplied with a binary transmission signal is capable of choosing between amplifying the transmission signal and entering a high-impedance state at an output. An antenna is supplied with a transmission signal output from the transmission amplifier. A comparator compares a signal received by the antenna with threshold values to obtain a reception signal, which is supplied to a processing unit. A capacitor is connected between the transmission amplifier and the antenna or between the antenna and the comparator. A control unit allows the transmission amplifier to be in the high-impedance state for a period during which the processing unit receives a reception signal.
