(reprint) Common Audio Protocol IntroductionIntroduction 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, hig

address Zen coding for Dreamweaver v.0.7 test Pass Is it a little confusing? Today, I'm going to introduce you to Zen coding, a set of tools for fast HTML and CSS encoding. Originally introduced by Vadim Makeev in April 2009 (the article in Russian), I developed a few months from my humble (i.e. I) and finally reached a more mature state. The Zen coding consists

Web page Production WEBJX article introduction: for engineers who are familiar with C + + or the Java language, JavaScript is flexible, easy to understand, and relatively loosely formatted for code. It's easy to learn and apply to your own code. Also because of this, JavaScript coding norms are often despised, the development process of tinkering, and eventually evolved into a follow-up maintenance personnel nightmare. Software exists For e

The coding methods and problems of win, PY, notepad++ first to say the conclusion: Because the default encoding used by Win CMD is GBK (ANSI), if it encounters bat or Python's Chinese needs to be displayed in cmd, if garbled, first check whether because it is not 1. GBK encoded in Chinese or 2. is converted to GBK encoding or 3 in code. In Python code, it is a Unicode object . do not in win under the text document editor with your own utf

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

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
