PS: Each layer has error correction, the physical layer has error correction level, belongs to the channel FEC code
Data link layer with CRC checksum, which belongs to the channel FEC code
Application layer, also has the application layer of FEC, that is, the source of FEC code
Application-Level forward error correctionBased on these shortcomings, the use of these error control technology does not guarantee the video transmission quality of IPTV ser

Supports multiple output modes, such as TS, ISMA, and HTTP, and can be directly received by STB, VLC Player, and Flash Player, the same video can be output to different network environment
It took a long time to compile vlc on linux. Therefore, it was specially recorded throughout the compilation process. Originally, I first wanted to use cygwin or msys + mingw for compilation on windows. Later, the boss came to the saying that linux is not compiled, but false linux will encounter problems, my goal is not to build a vlc version on windows, but to debug vl

At present, there are two directions for the development of communication networks. One is that the transmission layer shows the development trend of all-optical networks. From the ASON technology on the core layer to the FTTP technology on the access layer, there is no indication that the evolution of network bearer to light; in addition, service integration is based on IP addresses. The development of INTERNET makes IP addresses the most ideal service bearer protocol,
first two digits indicate the discard priority, for example, if the remainder of 34/8 = 4 is and the binary value is 010, 34 indicates that AF4 discards the datagram whose priority is middle.
If you arrange cs ef af and BE, you can find an interesting phenomenon, as shown in the following table. This table is the queue with the most application in reality. According to the PRECEDENCE priority of the IP address, CS7 is ranked at the highest order to BE the lowest. Generally, the Usage of these q

Cisco once again launched a new generation of router products and also applied new technologies. So I studied how Cisco developed the new VQE technology to solve the problem of IPTV Video Delivery. Here I will share it with you, I hope it will be useful to you. Cisco has announced the release of the VisualQualityExperience (VQE) technology to extend the Video Delivery Function of its next-generation Internet Protocol (ip ngn) architecture, thereby imp

Secondly, this has also impacted the development of emerging services such as IPTV and video phones.
At present, emerging services such as IPTV
1. First install the necessary dependent software, open the terminal, execute:sudo apt-get install git libtool build-essential pkg-config autoconf2.

Statement 1:
Although Isma and MPEG-2 ts over IP can be used for IPTV stream transmission, but due to the Mechanism and the original intention of different standards, there are some differences in IPTV service support, the specific analysis is as follows:
1. Support for business functions
Isma currently supports MPEG-4 and H.264 and does not support other encoding standards. As video and audio streams are t
