socket is sent. The I/O multiplexer will continue to transmit the next socket to the file event dispatcher after the event that the previous socket generated has been processed. I/O multiplexing programs are implemented by wrapping the I/O multiplexing Library of common Select, Epoll, Evport, and Kqueue functions. 2. Time Event Classification timed event: Specify time to execute once. Recurring event: Executes once at intervals. Currently, Redis onl

are synchronized, business threads are at risk of being synchronized blocking as long as they are IO, which can lead to poor reliability of the system, depending on the processing power of external components and network conditions. With non-blocking io (NIO), the three defects of synchronous blocking IO will be solved: NIO uses reactor mode, a reactor thread aggregates a multiplexer selector, which can register, listen, and poll hundreds of channel

Structured modelingA description of a signal resource allocation (or a combination of logical connections) in a module becomes a data flow description (Data-flow Description), or data flow modeling (Data-flow Modeling)A description of the behavior of the signal in the module, called the Behavior description (behavioral Description), or behavior modeling (behavioral Modeling)Organize many modules into a larger module, described as a structured description (Structural Description), or

, etc.). Subclasses that inherit from EventHandler can customize the behavior of the event handler. The reactor class is used to manage EventHandler (registration, deletion, and so on) and uses handle_events to implement event loops, constantly invoking a multi-separator select for a synchronous event multiplexer (typically the kernel), as long as a file handle is activated (readable/writable, etc.). Select returns (blocks), and Handle_events invokes

In the beginning to do the real problem, found that the computer system this piece of the problem is always wrong, so will For the composition of the computer hardware system and the relationship between the parts, we first come to a simple general summary: The computer hardware system consists of 5 large parts of the arithmetic, controller, memory, input device and output device. wherein, the arithmetic and the controller compose the central processing unit (CPU). The operator is responsible

the PTS/DTS flag in each frame. When inserting the PTS/DTS flag, For B-frames, it is not necessary to insert DTS in B-frames because PTS and DTS are equal in B-frames (see Figure 1). For I-frames and P-frames, the order of the packets changes after being reused, The display must be stored in the video decoder's sort buffer, and then displayed after a new sort. So be sure to insert both PTS and DTS as the basis for the new sort. Second, the synchronization mechanism Encoder System clock ST
