To achieve CD quality (16bit/44.1khz stereo) need 1411.2 kbit/s bandwidth, obviously Bluetooth A2DP cannot allow (Bluetooth 2.0/2.1 + EDR The largest carrier rate is about 2.1mbit/s, minus the protocol header, interference, power dissipation factor influence , the actual maximum transfer rate is approximately 1000bit/s), so the audio data needs to be compressed. We know that the same bit rate, different encoding format compression rate is different, thus decoding the quality of the restoration i

The basic idea of the Subband encoding (Subband CODING,SBC) is to use a set of Bandpass filters (Band-pass FILTER,BPF) to divide the frequency band of the input audio signal into several successive bands, each of which is called a subband. A separate coding scheme is used to encode the audio signals in each sub-band. When transmitting on a channel, the code of each child band is composited together. At the receiving end of decoding, the code of each

As a web development it is necessary to familiarize yourself with the request headers and the response headers of common HTTP. For example, the request header Content-type specified the content of the request, if the type is application/x-www-form-urlencoded, you can call Reqeust get the parameter method to fetch the content, if the other needs to call the method fetch stream. Another example of the respons

field: 16 bits. The TCP protocol identifies the source and target application processes by using ports. The port number can use any number between 0 and 65535. When a service request is received, the operating system dynamically assigns the port number to the client's application. On the server side, each service serves the user in the "well-known port" (Well-know ports). 　　 Sequence Number field: 32 bits. Used to identify the byte stream of data that is sent from the TCP source to the TCP des

HTTP request Header Overview (HttpServletRequest) An HTTP client (for example, a browser) that must indicate the type of request (typically get or post) when sending a request to the server. If necessary, the client can also choose to send another request header. Most request headers are not required, except for content-length. Content-length must appear for post requests. Here are some of the most common request
