Overview of BTU-2 APTX Bluetooth Receiver

       1. Introduction to Bluetooth

       As we all know, in today's rapid popularization of communication technology, when it comes to Bluetooth, I believe that everyone will not be unfamiliar with the word. As the most common wireless transmission in smart devices, Bluetooth was still a very fashionable word a few years ago. After so many years of evolution, Bluetooth technology has transformed from 1.0 on paper to an indispensable wireless module.

Why is it named bluetooth? It comes from a little story about a tenth-century Danish king named Harald Blatand, who was articulate and sociable. He unified Norway, Sweden and Denmark. Because he likes to eat blueberries, his gums are often blue, so he is known as the bluetooth king. The designers felt that the name "Bluetooth" was very expressive when deciding on the name, and the personality of King Blatand fit the characteristics of this technology, so the name "Bluetooth" was used. The Bluetooth logo design is derived from the letters of the "H" and "B" Bluetooth logos in the name of Harald Bluetooth, which are represented by ancient Nordic letters. Combining the two becomes the Bluetooth logo.

       2. Advantages of Bluetooth

       Compared with other wireless technologies: infrared, wireless 2.4G, WiFi, Bluetooth has many advantages, such as perfect encryption measures, stable transmission process and rich compatible devices. Therefore, it has been widely used in mobile phones, computer notebooks, and digital audio fields. It is especially favored by the younger generation of digital product enthusiasts. How to connect the large-capacity song resources in the mobile phone to the high-fidelity sound with good sound effect, so that the mobile phone can play high-quality sounds of nature, which has become a lot of young generation. A topic of interest to audiophiles of digital hi-fi music!

       To this end, we introduced the US CSR aptx high-fidelity Bluetooth stereo patent technology in the highly mature Bluetooth transmission technology. The apt-X technology is a real-time digital audio data compression system used in the field of professional audio and broadcasting. Linear audio samples are compressed to 1/4 of the original, with no noticeable loss of sound quality and extremely low latency. This technology enables its audio sound effects to be CD-quality. Greatly enhances the superior stereo audio sound quality in a Bluetooth connection, and its full audio frequency bandwidth matches high-fidelity performance. Solved the audio coding low latency technology to minimize the delay, and solved the "lip sync" and so on. Using the patented aptx high-fidelity Bluetooth stereo technology requires the purchase of the US CSR aptx patented technology, which is expensive, but the benefits it brings are obvious and effective.
