The average participant is capped by a 1% stake. The core par

Abstract: combined with the psi/Si information table in a TS stream of DVB-C Cable Digital TV, this paper analyzes the PSI Information of MPEG-2 and the various tables in SI information of DVB, this gives you a clearer understanding of the functions and functions of each table. Key words: Digital TV; TS stream; PSI information; SI information; Electronic Program

The Electronic Program Guide (EPG) is usually used in the DVB receiver to quickly find programs. The EPG data generated comes from the business information SI information in the DVB code stream. In digital TV, all the video, audio, text, pictures and so on after digital processing into the data, and according to the MPEG-2 Standard packaging, forming a fixed length (188 bytes) and then the data packets are reused to form a transmission code stream (TS). Generally, a channel corresponds to a TS s

TODO security issues are extensive and complex, I do not understand all of them, so this document will be constantly updated, but also hope that we have a lot of mistakes!The reason for this document is that the PSI has not been developed yet, but there are already users in the actual production environment, and asked me how to enhance security, so I began to write this document.1, the security of the database1.1 Principle 1: In a production environme

Today in the PSI QQ group chatting up the topic of the database foreign key, I wrote this blog post, said I on the database foreign key considerations.1, the database design should use foreign keys.2, very cup with, PSI database design so far, no foreign key.3, PSI will gradually put the database foreign key to fill up.4, some places really can not add foreign ke

At the same time I was thinking: a lot of questions about ExtJS and not very familiar with ExtJS basic knowledge points related, so I decided to write this series of blog.Note: These knowledge points are only applied to the PSI code, not the ExtJS

Before reading this article, it's best to take a look at this: http://my.oschina.net/u/134395/blog/3824471, PSI is currently written in PHP, but I decided to get a Java version!2, one of the reasons: Just for fun! (To Linus Torvalds Salute! )3, if you simply translate the PHP code into Java code, then this fun is not cool enough, so: Java version has its own unique planning.In summary, the PSI Java version

Look at the code firstExt.define ("PSI.Sale.wsmainform ", {extend:" Ext.panel.Panel ", border:0, Layout:" Border ", Initcomponent:function () {var me = this; The following code is slightly1, the main meaning of the above code is to define a new Class:PSI.Sale.WSMainForm, the parent class is: Ext.panel.Panel2, today's new knowledge point is: initcomponentIf you want to add new components to the UI, writing code in InitComponent is a must. So in many of the Ps
