Abstract
The invention relates to an HDMI video image output converter. The HDMI video image output converter comprises an HDMI input port, an HDMI conversion chip, an output port and a SCALER chip, wherein the HDMI input port is connected with the HDMI conversion chip, the HDMI conversion chip is connected with the output port, the SCALER chip is used for being adapted to the resolution ratio of an output device automatically, and the HDMI conversion chip is connected with the output port through the SCALER chip. The HDMI video image output converter has the advantages that the problem that HDMI video output converters in the prior art can not identify resolution ratios automatically is solved; a function of HDMI conversion AV output is added.
Description
Technical field
The present invention relates to a kind of video image output translator, particularly relate to a kind of HDMI video image output translator.
Background technology
HDMI converting video image in the market is output as the transducer of VGA/YPBPR, is point-to-point conversion substantially, can not change resolution.And format transformation is without the AV translation function, highest resolution that particularly can not the self adaptation display device
