Synchronous Optical Fiber Network (SONET) is an optical fiber transmission standard that focuses on the physical layer in the OSI model structure. Like SDH in the world, SONET was initially designed for the transmission of voice traffic over optical fiber networks. Like the first layer physical layer protocol, SONET is also used to ensure communication between va

SONET Optical fiber Transmission system defines the synchronous transmission of the line rate hierarchy, the transmission rate is based on 51.84mb/s, approximately corresponds to the T3/E3 transmission rate, which is called the 1th level synchronous transmission signal, that is STS-1; the light signal becomes the 1th stage optical carrier (optical Carrier, OC), that is, OC-1.

talk about what is intra-frame prediction and inter-frame prediction in the encoding process before understanding I-frame B-frame P-frames 1. Intra-frame predictive coding Intra-frame encoding is used to reduce spatial redundancy

In video compression, each frame represents a delicate image. In actual compression, various algorithms are used to reduce the data capacity. IPB is the most common one.To put it simply, I frame is a key frame and belongs to intra-frame compression. It is the same as avi compression. P indicates the forward search. B i

Live555 + FFMPEG how to extract key frames (I frame, P frame, B frame)When developing a Streaming Media Player, especially on the Windows Mobile and Symbian (s60) platforms, you may need to develop your own player.The s60 platform provides the cvideoplayutility interface to implement streaming media players. However, because it is not open-source, many operations

From the simplest of an HTTP request development, according to the TCP/IP protocol, separate the data frame structure of each layer, and how they assume the network service.Protocol stackThe Internet protocol stack consists of five layers:1. The application layer is where the network application and its application layer protocols persist. The application layer of the Internet includes many protocols, common HTTP (which provides request and delivery f

Frame B has four reference modes in the MPEG-4. If both the image compression before and after the reference is recorded, the difference between the pixel value of the front image + pixel value of the back image)/2 is recorded, that is, the difference between the image and the average image. Therefore, the number of Difference values recorded is the same as that of P frames. There is only one difference, which is not increased. Because BThe

After iOS 9.0, Apple officially announced no longer or no recommendation to use Uialertview and uiactionsheet to be replaced by Uialertcontroller. It's easy to use a controller to combine the two. The following is a common method of Uialertview #import "RootViewController.h" @interface Rootviewcontroller () @end @implementation Rootviewcontroller -(void) Viewdidload { [Super Viewdidload]; Create a button click on the show Bomb frame UIButton *bu
