Signal transmission system

Abstract

A signal transmission system according to the present invention, in one embodiment comprises: a signal transmission unit that includes a MPEG decoder which receives digital broadcasting and outputs a luminance signal Y and two color difference signals PB / PR, and a transmission path encoding circuit which encodes the YPBPR outputted from the MPEG decoder into signals in the forms suited to a transmission path and transmits the encoded signals; and a signal reception unit that includes a transmission path decoding circuit which receives the encoded YPBPR and decodes them, a Y processing circuit which processes the decoded luminance signal Y, a chrominance processing circuit which processes the respective decoded color difference signals PB / PR, a signal conversion circuit which converts the YPBPR outputted from the Y processing circuit and the chrominance processing circuit into RGB signals, and a display device which displays the RGB signals. According to the so-configured signal transmission system, it is possible to realize a signal transmission system in which hardware configurations of the video signal transmitting end and receiving end can be simplified.

Benefits of technology

[0011]Therefore, it is possible to realize a signal transmission system in which hardware configurations at the video signal transmitting end and receiving end can be simplified.

[0035]Therefore, it is possible to realize a signal transmission system which can set parameters for noise removal for every frame.

Problems solved by technology

However, in the above-described conventional signal transmission system, since the transmission path encoding is performed on the RGB signals, the output from the MPEG decoder is once converted into the RGB signals, encoded, and transmitted through the transmission path and, thereafter, the RGB signals must be converted into the YPBPR to perform signal processing again on the monitor side and, further, the Y color-difference signals must be converted into the RGB signals once again to output the RGB signals to the final display device, resulting in a drawback of requiring a lot of hardware.
