H.265 high-definition hard disk video recorders are initially used in the fields of security and monitoring in finance and transportation. Image acquisition equipment such as cameras save required monitoring content in a specific format on the hard disk, so that any content can be selected for playback at any time. ? Definition of H.265 HD DVR: Since the storage medium is based on a hard disk rather than a traditional magnetic tape, we simply call it a “hard disk video recorder”. Through configuration, the digital hard disk video recorder can easily achieve data format conversion, encrypted storage, remote control, bit rate control, and multi-channel simultaneous recording and playback. These features based on new technologies in the electronics and communications industry in recent years make it completely suitable for monitoring. Replaces traditional video recording methods based on traditional tape media. These new features, especially their high reliability and reusability, are also very attractive to the TV production and broadcasting industry. However, unlike the electronic surveillance field, the requirements of the TV industry for video recorders are not only to have “recording” functions, but also to achieve “high quality” recording and playback functions. In other words, it is required that the image quality of the recorder must be at or near the broadcast level, that is, the digital video standard for the studio specified in the CCIR601 (ITU601) document, such as a sampling rate of 13.5MHz, a quantization bit of at least 8 bits, and a sampling ratio of 4: 2: 2, Standard data stream 27MB / s and so on. At the same time, due to different application areas, the television industry requires higher reliability, longer mean time between failures, and better maintainability for the use of video recorders. Therefore, the hard disk video recorders used in the television program production and broadcasting industry have many characteristics that are different from those of ordinary hard disk video recorders. Each company also makes different designs based on different considerations. Next, let's first analyze the overall system configuration of the broadcast-level multi-channel hard disk video recorder. ? The main functions of H.265 HD DVR: 1.
