Description
Technical Field
The utility model belongs to the technical field of high-definition video playing, and particularly relates to a large-screen player, an intelligent television, a television box, a cloud server and a vehicle-mounted terminal.
Background
The 8K resolution is a digital video standard in experiments, and is promoted by organizations such as japan broadcast association (NHK), British Broadcasting Company (BBC), and italian broadcast television company (RAI). On 8/23/2012, the international telecommunications union under the united nations flag was developed by NHK from 1995 by regarding the resolution of 7680x4320 suggested by the NHK television station in japan as the international 8K super high definition television (SHV) standard and SHV as an "ultra high definition video system" exceeding the current digital television.
In order to accelerate the rapid and healthy development of the ultra-high definition video industry, 8K application is falling to the ground gradually, the ultra-high definition 8K can bring the sense of fineness exceeding the image quality of the traditional broadcasting and television, meanwhile, the color reduction degree of 8K reaches 75.8%, and colors which cannot be seen in 4K and 1080p can be seen. However, in the 8K video processing, there is a great problem because of its large data amount. Taking 24 frames of 8K video as an example, if the color depth of each bit reaches 6 bits, the bandwidth for processing single-channel 8K data needs to be as high as 14.3Gbps, and massive data processing brings a very big challenge to the current video processing system.
In the field of large-screen splicing at present, the maximum resolution of a single channel can only reach 4K, and no professional splicing controller can process the resolution of 8K. Such huge data volume needs a special chip to collect at the video collection end; when data transmission is carried out, a data transmission channel is specially designed for the high bandwidth to carry out transmission; in the video processing block, no splicing controller can directly perform processing such as superposition and scaling of 8K videos at present.
Through the above analysis, the problems and defects of the prior art are as follows: at a video acquisition end, no special splicing controller is available for video processing at present, the processes of superposition, scaling and the like of 8K videos can be directly carried out, the high resolution display of the existing large screen is realized through a video splicing technology, and the existing splicing controller adopts the HDMI2.0 standard, has the highest bandwidth of only 18Gbps, can only transmit and process 4K video data and cannot directly transmit the 8K videos. With the slow popularization of 8K video, more of the 8K video is applied to large-screen end display, and the large screen generally adopts a splicing technology to realize ultra-high resolution display, but at present, a splicing controller only supports the input of hdmi 2.04k signals, and cannot directly process 8K video data.
The difficulty in solving the above problems and defects is:
because the existing equipment only supports HDMI2.0, but can directly receive and process 8K video, the equipment needs to support 8K decoding instead of transduction, supports a processing chip of an HDMI2.1 protocol, and performs video segmentation and splicing on the basis of the signal and then displays the video on a large screen, hardware and software need to be redesigned, and the development period is long.
The significance of solving the problems and the defects is as follows:
because 8K is gradually popularizing at present, under large-screen display scenes such as markets, conferences, monitoring and the like, higher resolution needs to be supported, and a better viewing effect is achieved, but the existing scheme can only process 4K video data at the highest path, and can not directly process the 8K video data, the large-screen player directly adopts the latest Hisi 8K AVS3 chip scheme, decodes 8K video data, outputs 4 paths of HDMI2.0 signals through a video divider, can be directly used for the current large-screen splicing controller equipment, achieves the effect of displaying and outputting 8K60hz video, and solves the problem that the current large-screen control system can not directly process the 8K signals.
