Embodiment Construction

[0026] The invention simplifies the rebuilding process of the multimedia data when the multimedia service quality is evaluated by establishing the index between the sent data identification number and the multimedia data, and is beneficial to monitor the performance of the multimedia service on multiple receiving ends at the server end.

[0027] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] The first step is to establish an index between the sent multimedia data identification number and the corresponding multimedia information.

[0029] The multimedia data identification number sent is the sequence number sent by the encoded multimedia data. In the RTP protocol, the multimedia data identification number sent is the RTP packet sequence number; in the TCP / IP protocol, the multimedia data identification number sent is the IP packet sequence number; In the H.324M protocol, the multimedia data...

Abstract

The invention discloses a method for monitoring multimedia data based on index, the steps are as follows: indices between a transmitted multimedia data identification number and corresponding multimedia characteristic data is established at a server terminal; the indices include data package numbers, data types or index data; the data package number means the multimedia data identification number that is received or transmitted; the data type means the type of the multimedia data package, the index data means the multimedia characteristic data corresponding to the data package number; after feeding back the multimedia data identification number corresponding to the false multimedia data package to the server terminal, a receiving terminal looks for the multimedia characteristic data corresponding to the multimedia data identification number in the indices of the server terminal and monitors multimedia service performance according to the multimedia characteristic data. By establishing the indices, the invention simplifies the reconstruction process of the multimedia data, thus being favorable for monitoring the multimedia service performance to more than one receiving terminals at the server terminal simultaneously.

Description

technical field [0001] The invention relates to a multimedia information transmission and processing technology, in particular to an index-based monitoring method for multimedia data. Background technique [0002] With the development of wired and wireless networks and the drive of user needs, multimedia technology and related applications have received more and more attention, and are considered to be one of the mainstream applications of high-speed networks in the future. Multimedia applications include video applications and audio applications. Compared with traditional Internet applications such as WWW and E-mail, the demand for bandwidth is greater. Existing multimedia data transmissions such as video and audio adopt high-compression coding techniques, which use the time, space and statistical correlation of multimedia information such as video and audio to perform data compression. Compressed multimedia data is very sensitive to transmission errors. In particular, exi...
