Reflections and thoughts

Doing business is something that requires mental and physical strength.The continuation of the company relies on the accumulation of the past,the accumulation of time consumed is not infinite. Some companies are flow thinking, some are product thinking. We temporarily belong to the latter, the former latter is not superior or inferior, past thinking confined to the latter, did not think about the former, the two do not conflict, future growth comes from the new organization of the former, as well as the continued maintenance of the latter. The mission and values of the company are extremely important when the company enters the mid-term. The mission needs to be deeply understood and believed in by the founder, it is the compass of the company, the key guiding factor of the second, third…n curve, and is a great challenge for the founder. Both of these are very difficult and very important, and are long-term projects. Investment some industries to achieve the first only 5 billion market value, some industries do a sloppy 50 billion market value, the track is limited to pursue greater breakthroughs inescapable problems, limited by one of the reasons, too early to start, not deep enough knowledge, web era entrepreneurs natural disadvantage in the more efficient short video live era, limited by the second reason, organizational capacity is limited, can not be fast and agile to new opportunities The second reason for this limitation is the limited organisational ability to organise new opportunities quickly and agilely.

How to get 8k on display and bitstream surround sound at the same time?

With the rise of 8K displays, 8K content, and HDMI 2.1 sources, it’s time to talk about 8K audio video distribution. Consumers are buying 8K TVs and gaming consoles, but their other devices are 4K, or 1080p. Going directly from the 8K gaming console to the 8K TV works great,but what if you want surround sound too? If you want bitstream surround sound audio from HDMI 2.1 sources like a PS5 or XBOX Series X, you could try to go directly from the source into an AVR.But most AVRs can’t handle 8K or HDMI 2.1, and the signal won’t get through to the TV. How do we get 8K on the display and bitstream surround sound at the same time? With our 8k Matrix switcher 4×2, you can watch 8K content and listen to full surround sound audio without sacrificing video quality. It is an 8K matrix switcher with 4 HDMI inputs and 2 HDMI outputs. It supports HDMI 2.1 features like high frame rate, variable refresh rate, uncompressed audio, and 8K video resolutions up to 40Gbps (FRL5), making it ideal for 8K audio video distribution. But how do we get the surround sound to work? AVRs will still cut the video quality down if they can’t handle the massive 8K 30hz or 4K 120hz content. We can get around the AVR with the 8K Matrix Switcher 4×2. One of the HDMI outputs has a built-in video downscaler that can take 8K and scale it down to 1080p without messing
