Abstract

Object To transmit well a video signal of a desired bit rate within a transfer bit rate of a transfer path. Solving Means A control unitcontrols the operation of data compression units-through-and switch unit. When the bit rate BR of a non-compressed video signal output from a codecis within the transfer bit rate BRof an HDMI transfer path, the control unitsupplies the non-compressed video signal output from the codecto the HDMI transmitting unitas a video signal to be transmitted. On the other hand, when the bit rate BRis greater than the bit rate BR, the control unitselects a compression method that can be handled on the receiving side performs compression processing so that the bit rate BRbecomes lower than the bit rate BR, and supplies the compression video signal to the HDMI transmitting unitas a video signal to be transmitted. Also, the control unittransmits compression information (control information of the switch unitand data compression units-through-).
