Embodiment Construction

[0035] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0036] The compression process of monitoring information is as follows:

[0037] like image 3 As shown, it is a monitoring information storage diagram. In this example, 1400 bytes are used as the size of a monitoring information data packet. Among them, the data length of the common part is 24 bytes, and the length of the variable part is 1376 bytes. The compression method of streaming media monitoring information is as follows:

[0038] Step 1: Declare a variable i for counting, the initial value of i is 1; declare a variable such as image 3 For the structure variable of the structure shown, apply for a storage space of 1400 bytes. According to this algorithm, it can be seen that the storage space of the public part is 24 bytes, and the storage space of the message part is 1376 bytes.

[0039] Step 2: Obtain th...

Abstract

The invention discloses a monitor information compressing method orientating streaming media transmitting quality. Monitor information monitored by the steaming media transmitting quality is set to be a public part and a change part so as to compress the monitor information of continuously received streaming media messages, especially, parameters of message sequence numbers, message arrival time and the like in the monitor information are subject to efficient lossless compression by using the information of the public part in the method. According to the method, the transmitting efficiency of the monitor information monitored by the streaming media transmitting quality is improved by 3-4 times, thus the network resources occupied by the monitor information during the transmission are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an IP-based monitoring information compression method for streaming media transmission quality monitoring. Background technique [0002] With the rapid development of computer network and streaming media technology, streaming media has become the mainstream of Internet applications, especially with the rapid development of IPTV business, people are interested in IP-based video conferencing, video on demand, distance learning, online games and entertainment, etc. The demand for multimedia real-time applications is increasing, and the requirements for transmission quality are also getting higher and higher. But the IP network is a network that only provides "best effort service", and it cannot guarantee the quality of streaming media transmission, so it contradicts the current requirements of people. Therefore, it is necessary to monitor the quality of streaming medi...
