Abstract: 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.

Abstract: 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.

Abstract: An information processing apparatus includes the following elements. A generation unit generates a multiplexed video frame having a predetermined screen size, and inserts first information regarding a configuration of the multiplexed video frame into the multiplexed video frame. A first multiplexing unit arranges one frame of input video data in the multiplexed video frame, multiplexes data of the frame so as to be transmitted as data of the multiplexed video frame corresponding to an arrangement position, and inserts second information regarding the arrangement position and third information regarding a format of the video data into a multiplexed video frame obtained after multiplexing. A processing unit extracts the data of the frame multiplexed in the multiplexed video frame obtained after multiplexing, which is input from an input video port, in accordance with the first information, the second information, and the third information, and performs processing on the extracted data.

Abstract: During the carrying out of a dim effect, a signal generated at a generator is mixed with a video signal and a matt signal at a mixer, a key signal and background signal are added at an adder, and the resultant signal is outputted. During the carrying out of a fade effect, in similar manner, the signal is mixed with the key signal and a fixed value signal at the mixer, the video signal and background signal are added at the adder, and the resultant signal is outputted. Extended dim effect and extended fade effect give depth to a picture with a color approximation where the depth of the image does not completely merge into the background.
