Today we will take a look at the black technology in Xiaomi TV 4A! HDR 10 can be seen as a low-level version of Dolby Vision. The version of Dolby Vision cannot be generated from the HDR10 version, but vice versa. The HDR10 is obviously a compromise product that standard setters have made to meet the average performance of most devices. It is free, but it is minimal free. The cost is that the HDR10 is incompatible with the SDR, and the color depth is only 10 bits. With static metadata, the mapping capability between different device capabilities is insufficient. After abandoning these, HDR10 then became a free-licensed universal HDR standard. The HLG (Hybrid Log-Gamma) is an HDR standard jointly initiated by the British BBC and Japan's NHK. It allows TV broadcast signals to be compatible with both HDR and non-HDR TVs. The reason why HLG technology can achieve compatibility between the two is mainly due to the fact that the signal contains no element data and can be compatible with the transmission equipment and display equipment of the current television broadcasting. The more important point is the license-free fee and is more conducive to HDR technology. In the field of wired, wireless and satellite television applications. With Dolby Audio, movies, TV shows, music, and games can be enhanced with sound effects from multiple levels. Dolby Audio technology provides up to 7.1 channels of surround sound, including virtual surround sound from any source and transmitted through headphones. The DTS-HD is a coherent acoustic audio coding system that includes original DTS digital surround sound, DTS-ES and DTS 96/24, plus lossless compression. But it has a higher interchangeability and expansion, in addition to taking into account a higher sound quality, more channels, but also compatible with the network to download the interactive content of the DTS-HD logo content. The sampling frequency and channel selection are also more flexible. However, the compression ratio is still smaller than the DD+, so the loss of sound information is less and the details are more abundant.
