Problems solved by technology

[0009] However, when the server and the client use the network to communicate, if the wireless channel conditions become poor, a large amount of data will be lost, and the decoder will not be able to decode this data, so that the picture will be static. At this time, only Restart the multimedia application to continue receiving streaming services
[0010] At the same time, if an error occurs in the decoding servo system, it cannot be automatically restored. Therefore, the problem here is that the data received through the network cannot be normally decoded.

Embodiment Construction

[0028] Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

[0029] figure 2 It is a flowchart showing the wireless streaming media transmission process according to an example of the present invention.

[0030] In the above example, the streaming media server is composed of the following parts: real-time media source 202; MPEG2 encoder 203; source filter 204; network rendering filter 205; Winsock API (206); TCP / IP layer 207; MAC layer 208; Network source filter 209; MPEG2 demultiplexer filter 210; Decoding filter 211; Display stacker 212; MPEG2 decoder 213; Run analyzer 214; Streaming media client application 215; Network monitor 216.

[0031] The above example schematically shows the process of transferring streaming media data from the streaming media server to the mobile terminal client.

[0032] Refer to figure 2 It can be seen that the streaming media server encodes the real-time multimedia data 202, and transmits the...

Abstract

A mobile terminal client end for identifying and restoring error operation of decoder consists of network monitor for monitoring stream media data to identity lost situation of data and operation analyzer for judging that data loss is caused by decoder operation error or caused by radio transmission if data loss of said stream media is identified.

Description

【Technical Field】 [0001] The invention relates to a mobile terminal client that can identify and restore decoder operation errors. Specifically, the present invention relates to a mobile terminal client with the following functions: when the mobile terminal client uses a wireless network to communicate with a streaming media server, the short-term deterioration of the wireless channel conditions will cause data loss and occur The decoder operates incorrectly, and the present invention is based on the analysis of the operation, identifies the problem from the software side, and restores it. 【Background technique】 [0002] At present, in order to provide users with multimedia streaming media, methods such as MPEG are used to encode the streaming media, and the encoded data is transmitted through the network. In order to decode and display on the client side, various applications have been developed. [0003] Generally speaking, this kind of application program is generally composed...
