---------------------- Objective ----------------------- H264 is a new generation of coding standards, with high compression quality and support for a variety of network streaming media transmission is known, in terms of coding, I understand his theoretical basis is: the reference to a period of time the image of the statistical results show that in the adjacent several images, the general difference in pix

I started to learn the encoding theory, but the more I learned it, the more I went into the fire. Why does coding solve the channel error? Redundant, yes, but there is always a lack of quantitative analysis and strict proof, getting dizzy and reluctant to look at the logic of different channel coding. Then I started to learn from information theory and gradually gained a quantitative understanding of the s

Developers are sure to be familiar with Base64 coding, and whether or not they have a clear understanding of it is not necessarily. In fact, Base64 is simply no longer easy, and if it's understood or ambiguous, it shouldn't be. About Base64, take a few minutes to get a thorough understanding of it. The article below is affixed with a Base64 codec, easy to read the article at the same time to experiment.　　I. BASE64 code ORIGINWhy do you have Base64 cod

Java coding specifications 1.1 why coding standards are especially important for programmers, there are several reasons: 80% of the cost of a software life cycle is maintenance. Almost no software is maintained by the original developer throughout its lifecycle. Coding specifications can improve the readability of software and allow programmers to understand new

General CSS coding specifications and general css Coding General CSS coding specifications In summary, some front-end encoding specifications are provided first, and most of them are common. It should be the mainstream method.1 Preface The goal of this document is to make CSS Code consistent in the style of the team, which is easy to understand and be maintained

PCM (Pulse-code modulation) Pulse coding modulation, pcm Pulse Coding modulation In audio processing, we often hear PCM data. What is PCM Data?PCM data is a digital signal after the analog signal passes through PCM. PCM is the process of converting the audio signal from analog signal (time continuous, value continuous) to digital signal (time discrete, value discrete. Digital signals have many advantages,

1. If you are in front-end development or web development, you must have heard of Zen coding-a quick way to write html/css code. It uses the syntax of the faux CSS selector to quickly develop HTML and CSS-developed by Sergey Chikuyonok.Now it is renamed to Emmet, and a new website has been built: Docs.emmet.io.2.

C # Coding Standard-coding habits 1. Avoid placing multiple classes in one file. 2. A file should have only one namespace. Avoid placing multiple namespaces in the same file. 3. A file should not exceed 500 rowsCode(Excluding the code generated by the machine ). 4. The code length of a method should not exceed 25 lines. 5. Avoid more than five parameters in the method.

Reprinted please indicate the source: http://blog.csdn.net/horkychen (Excerpt from msdn-coding techniques and programming practices) Names) Naming is most helpful for understanding the logical structure of a program. A name description is "what" is more important than "how. Naming can avoid exposing the underlying implementation, thus retaining an abstract layer, simplifying the complexity of the program. For example, you can use getnextstudent () in

Manchester Encoding(Manchester Encoding), also known as Phase Encoding (PE), is commonly used for LAN transmission. In Manchester Coding, there is a hop in the middle of each bit. The hop in the middle is both a clock signal and a data signal. However, in different books, in Manchester encoding, the value of the level beat expression is different, which produces many ambiguities: 1.
