A little products do not support 4K*2K/60Hz 8 YcbCR4:4:4 signals, while also can not meet HDCP2.2 requirement.
In TV and the demonstration of other display devices, having many platform display devices need to be while be demonstrated.And have
Different brands, the display device of different resolution is demonstrated simultaneously.The distributor that existing market is sold is in order to be able to making each display device
There is image output, minimum resolution ratio can be taken to export.
For the TV of high definition, the advantage of high definition can not be embodied.Export high-resolution image if desired, it is necessary to
The display device of low resolution is removed.Access, so operate quite cumbersome again after the completion of demonstration.
HDMI products applications are increasing on Vehicles Collected from Market, and HDMI multiplexing product also occurs in succession, and species is various.And
HDMI 1.3 currently used in the market and the HDMI mono- of 1.4 editions, which enter to have more point device and the utility model, similarity, but this
A little products do not support 4K*2K/60Hz 8 YcbCR4:4:4 signals, while also can not meet HDCP2.2 requirement.
In addition, the HDMI mono- for selling 1.3 and 1.4 editions in the market enters six and goes out distributor, it is simply simple to distribute work(
Can, HDCP2.2 is not supported, the most important is not support 4K*2K/60Hz 8 YcbCR4:4:4 signals, user is in demonstration
Process has no idea best effect to show guest to see, so as to not reach optimal distribution effect.
Utility model content
Technical problem to be solved in the utility model is to provide one kind will all the way with advanced high-definition multimedia technology
