Abstract: The present disclosure relates to the technical field of hexanediol production, and provides a production method and a production device of high-purity 1,6-hexanediol. A dipic acid and a C6 mixed alcohol are mixed to conduct esterification to obtain a product feed liquid including an adipic acid diester, and the high-purity 1,6-hexanediol is obtained through hydrogenation reduction and distillation. In addition to being used as a reaction raw material, the C6 mixed alcohol further acts as a water-carrying agent; water produced by the esterification is removed by azeotropy, thereby promoting a smooth reaction process to realize the esterification without a catalyst. The method does not need the catalyst during esterification, and the subsequent hydrogenation reduction can be directly conducted with no complicated post-treatment procedure required after the esterification.

Abstract: A system and method are disclosed is to prevent the screen tearing in a video display system with self-refresh features while limiting space used for memory size in the self-refreshing sink device. A flexible method is utilized to manage a frame buffer and control self-refresh display timing to prevent screen tearing. The sink device has capabilities including one or more of self-refreshing and applying single frame updates as well as burst single frame updates while self-refresh is active. The memory utilized by the frame buffer during self-refresh is limited to less than that needed to store two full frames of video.

Abstract: A system and a method are disclosed for enabling fast switching in a multimedia interface system having content protection. By using a partial port receiver to decode a portion of the input at input ports that are not being output to a multimedia sink, the design of the switching system is simplified and silicon costs are reduced. Additionally, the switching system and method reduces the switching delay by maintaining content protection signaling with all of the input ports. This eliminates the need for re-authentication when a new multimedia source is selected.
