Abstract: A video apparatus according to the present invention includes: an information process portion that records or plays play information which includes video or audio, a communication portion that connects to a communication network to perform communication, and a control portion that executes a control program. Besides, the video apparatus allows a change of the control program in a case where a predetermined condition is met. Besides, the video apparatus includes a communication control portion that controls the communication portion to perform communication with a predetermined information process apparatus which is connected to the communication network. Besides, the video apparatus include a calculation portion that receives calculation data necessary to perform a calculation process from the information process apparatus; performs calculation that uses the calculation data; and transmits calculation result data which indicate a result of the calculation to the information process apparatus.

Abstract: A plurality of standard television broadcast programs recorded on a recording medium are selected. Video and audio signals of one of the selected plurality of standard television broadcast programs are reproduced. Markers are attached to a standard video-and-audio part of the reproduced video and audio signals of the one of the selected plurality of standard television broadcast programs. The standard video-and-audio part is registered. Video and audio signals of another one of the selected plurality of standard television broadcast programs are serially reproduced. The reproduced video and audio signals are compared with the standard video and audio signals of the registered standard video-and-audio part to thereby determine a video-and-audio part of the reproduced video and audio signals, which is substantially matched with the registered standard video-and-audio part.

Abstract: When there is a key operation, the number of times of selection or the number of times of cancellation corresponding to the command or the menu item for which the key operation was made is rewritten. When a “enter” (select) button is depressed for selection, the count for the number of times of selection is incremented by 1. When a “return” button is depressed for selection, the count for the number of times of cancellation is incremented by 1. The number of times of execution is obtained by subtracting the number of times of cancellation from the number of times of selection, and the display order is set in accordance with the number of times of execution thus obtained.
