VIDEO TRANSMISSION PROCESSING DEVICE |
摘要 |
PURPOSE:To freely revise and set the resolution and the frame rate of com pressed data sent from a connected terminal equipment by providing a connec tion destination control signal generating section to the terminal equipment so as to allow the receiver side to control the compressed data. CONSTITUTION:The size of a display pattern of a video image or the lightness or the like or a sound level inputted to a speaker 109B and a frequency characteristic or the like is controlled through a command via a control input device 108. In this case, a video/sound indication reproduction control section 103B outputs a display state of a video image and a reproduction state of a sound signal to a connection destination control signal generating section 104B. The connection destination control signal generating section 104B outputs a control signal to a transmission data compression control section 105A of a terminal equipment 101A of a connection destination in response to the state of a status signal. Thus, a compression parameter of transmission data or the like is controlled at the receiver side in a form corresponding to the display content on the display monitor 110B at the terminal equipment 101B or the sound reproduction state of a speaker 109B. |
