Abstract: A wireless moving image and audio transmitting system capable of enhancing the display quality of moving image and output quality of audio without expanding the bandwidth of radio communication is disclosed. The wireless moving image and audio transmitting system comprises a moving image and audio transmitter and a portable display terminal. When the portable display terminal is near the moving image and audio transmitter, the sound input from the audio input unit of the moving image and audio transmitter is directly output from the speaker of the audio output unit. At this time, the moving image and audio transmitter transmits the input moving image at a low compression rate to the portable display terminal. Thus, the display quality of moving image and output quality of audio can be enhanced without expanding the bandwidth of radio communication.

Abstract: A system for remote control of host computer by client computer is disclosed. The client computer converts the operating procedure of its pointing device into operation information including data about switch operation, coordinates data, and time interval data between operations, and transmits the operation information to the host computer. The host computer decomposes the received operation information into the original operating procedure, and reproduces the original operating procedure. Thus, the operating procedure of the pointing device transmitted to the host computer is prevented from having effects of irregular delay of the network.
