Elementary stream In the MPEG-2, bit streams that contain encoded images, sounds, or data are called the basic stream ES (elementary stream ), it only contains one type of data (audio, video, or subtitle). What we call "audio", "video", or "bit stream" is elementary stream, the format is generally determined only by the data contained (such as the video codec ). Packetized elementary streamAfter packaging, es becomes the package's basic stream PES (packetized elementary stream). It can synthesi

Iimax®Solutions has rich experience in optical fiber cabling and LazrSPEED®High-performance products such as TeraSPEEDTM, InstaPATCHTM Plus, and LC connector. After years of research, the IMAX Laboratory analyzed the cost of the complete Optical Fiber System and concluded that the optimization of NM applications on Multi-Mode Optical Fiber enables the most benefits to users, the second is the application of 1300 nm on single-mode optical fiber.It is worth mentioning that SYSTIMAX LazrSPEED®Multi

Abstract: This article describes the conversion algorithms of common encodings in detail after sorting out various types of data. I. general character set (UCS) ISO/IEC 10646-1 [ISO-10646] defines a character set of more than 8 bits, known as the general character set (UCS), which contains most of the world's writeable character systems. Two types of multi-8-bit encoding have been defined, and each character adopts four 8-bit encoding called UCS-4, a

During word or Excel operations, the interoperability type "…" cannot be embedded in vs2010. Use the applicable interface to solve the problem. When I asked du Niang, the solution was exactly the same: select the DLL introduced in the project, right-click the DLL, select properties, and set "embedded interoperability type" to false. After the problem is easily solved, many people may wonder what this "embedded interoperability type" means? Next let me go slowly. (If you don't have much time, che

Video is an important part of Multimedia Systems in computers. To meet the needs of video storage, people have set different video file formats to put the video and audio in one file for simultaneous playback. Video files are actually a container that contains different tracks. The Container formats used are related to the scalability of video files. FourCC is the Four-Character Codes. It consists of 4 characters (4 bytes) and is a Four-byte format that uniquely identifies the video data stream,

This note does not cover this issue. It is only pointed out that although multiple bytes are used to represent a symbol, the Chinese character encoding of the GB class has nothing to do with the Unicode and UTF-8 of the subsequent text. 3.

We call this design a dual-interface card.The idea of this article is how to design the chip architecture reasonably, so that the CPU, operating system software and external interface are irre

Many even some books on the market use void main (), which is actually incorrect. Void main () has never been defined in C/C ++ (). The father of C ++ Bjarne stroustrup clearly states the definition void main (){/*... */} is not and never has been c ++, nor has it even been c. (void main () never exists in C ++ or C ). The following describes the definition of the main function in the C and C ++ standards respectively.1. cIn c89, main () is acceptable. Brian W. kernighan and Dennis M. Ritchie us

To achieve load balancing on both sides, you need to throw task A to Controller A and Task B to Controller B, for the same task, only one controller is under control at any time. A/P: Active/Passive. For A specific LUN, the target port of A controller is in the active/optimized status in its path, the target port of another controller is in the standby status.
