HVD

HVD is an abbreviation for English High-definition Versatile Disc. HVD combines powerful functions, clear images, low prices, superior backward compatibility, key technologies, and independent intellectual property rights. It contains a 24-bit DSP, a 24-bit CPU, a 32-bit CPU, and a lot of decoding hardware and image post-processing hardware, equivalent to 1G of Pentium computing capabilities, is the highest level of integrated high-definition video on the market decoder. The HVD's horizontal resolution and vertical resolution all reach the 720-line high-definition standard. HVD is very suitable for the technical status of Chinese electronic products. First of all, high-definition television and television do not support 1080P capabilities. The vast majority of products only support 720P and 1080i. Second, from the perspective of video compression, 720P supports progressive line, small jitter, and is suitable for high-definition video. Finally, considering the compression efficiency, The 720P has a low bit rate and is suitable for storing a complete movie on a single disc. This kind of optical disc is in the field of red light technology and has a lower cost, so the HVD has three major advantages of high definition, low cost, and matching with high-definition television. The format supported by HVD is (P stands for Progressive, I stands for Interlaced):
