ABSTRACT:
A remote operation system includes a server and a client. In the server, a video-audio data conversion-into-common-format section converts data in a format unique to application software into data in a common format. A video-audio distributing section outputs audio-accompanying video data and moving-picture area data from the data in the common format. A section, which processes the transmission of the data of audio-accompanying moving-picture, adds a synchronizing data to video data and audio data, thereby obtaining a data stream. A video-audio data converting section outputs data including the moving-picture area data, operation-related audio display data. A remote control section outputs this data and the data stream. The client controls the application software of the server in response to an operation related to the video and the audio obtained from those data.
