Introduction and comparison of common audio protocols for conference TV white PaperFirst, the digital audio principle: The sound is actually a kind of energy wave, therefore also has the frequency and the amplitude characteristic, the frequency corresponds to the time axis, the amplitude corresponds to the level axis. Usually the ear can be heard in the frequency of 20Hz to 20KHz of sound waves known as audible, less than 20Hz to become infrasound, higher than 20KHz for ultrasound, multimedia te

between English characters and bits. This is known as the ASCII code (American Standard Code for Information Interchange), which has been used so far.The ASCII code specifies a total of 128 characters, such as a space "space" is 32 (binary 00100000), the uppercase letter A is 65 (binary 01000001). These 128 symbols (including 32 control symbols that cannot be printed out) take up only one byte of the latter 7 bits, and the first 1-bit uniform is 0.2. Non-ASCII encodingIt is enough to encode 128

Python Coding knowledge Coding Introduction Kinds Storage units 1. Introduction to CodingEncoding is the process of converting information from one form or format to another, also known as a code abbreviation for a computer programming language. The text, numbers, or other objects are digitally digitized by a predetermined method, or the information or data is converted into a prescrib

I. Coding and decoding involved in the Java Web We all know that for Chinese, where I/O is involved in coding, I have already mentioned I/O operations can cause coding, and most I/O generated garbled is network I/O, since almost all applications now involve network operations, and data is transmitted over the network in bytes. So all data must be able to be seria

Directory (?) [+] Introduction to Huffman coding Huffman encoding is the binary encoding pairing of characters and characters, which is divided into encoding and decoding to compress the binary data length of characters. We know that character storage and transmission are binary (the computer only knows 0/1), then there is the mapping relationship between the character and the binary. Characters belong to character sets (Charset), characters need to b

But I this feature is the principle of investigation, I care about things want to understand, so the QQ group in turn send information, no one heeded. Alas, depressed. Had to own Google it and teach myself. The following is a detailed description. There is no one to ask for help, I have some personal thoughts. Nowadays people have very few to delve into theory, people's idea is to muddle along, people usually just know what, do not know why. For programming, individuals think this is a sad thin

H.265/HEVC's coding architecture is broadly similar to the H.264/AVC architecture, including, in-frame prediction (Intra prediction), inter-frame prediction (inter prediction), conversion (transform), quantization (quantization), de-block filter (deblocking filter), Entropy coding (entropy Coding) modules, but in the HEVC cod
