Although this method can solve the above problems, in order to obtain a target file with ideal space occupation and encoding quality, the re-encoding process needs to do a lot of calculations, so it takes a long time, usually one to two times the playback time of the original file It takes time to complete, it is not real-time, it is unbearable
[0005] In the home of most users with embedded streaming media players, basically also have a personal computer at the same time, and if you just watch movies on a TV or projector, you don't need the inefficient way of file transcoding at all
Some users directly connect the computer to the TV to play, but the computer and the TV are usually not put together, and it is also a cumbersome process to reconnect the computer every time.

Embodiment Construction
[0022] The present invention will be specifically described below in conjunction with the accompanying drawings.
[0023] Reference attached figure 1 , a method for expanding the decoding capability of streaming media playback devices, the main process is:
[0024] The playback device and the decoding device first establish a communication connection through the network transceiver module. In this example, Ethernet and TCP / IP protocol are used for network communication;
[0025] 1. When starting to play, the player checks the original streaming media format. If it finds that the device does not have the corresponding decoding capability, it requests the decoding device for assistance in decoding and points out the location of the original streaming media. In this example, the original streaming media exists in the playback device in the form of a file, and the playback device opens the original streaming media file to the decoding device through the Windows file sharing proto...

Abstract
The invention relates to a method of enlarging the decoding ability of the stream media playing device, belonging to the technical field of computer media. The method utilizes the network so that the playing device is able to utilize the decoding device on the network to decode, thereby finishing the work of decoding playing. The playing device firstly detects whether the initial bit rate belongs to the bit rate which the device cannot decode; if so, the decoding work is transmitted to the decoding device on the network; the decoding device decodes the given initial bit rate and transmit in network; the playing device is able to send the format in decoding playing mode to the playing device; the playing device decodes and plays the bit rate transmitted by the playing decoding device to finish the whole work of decoding and playing; further, the playing device controls the decoding work of the decoding device. The invention is able to be used in the multimedia player, IP set-top box, bidirectional digital television set-top box having computer network interface so that these devices can play the stream media contents in plurality of formats.
Description
technical field [0001] The invention relates to a streaming media decoding method, which belongs to the technical field of computer multimedia, in particular to a technology for realizing remote decoding by using a network. Background technique [0002] At present, the encoding and decoding algorithms and formats of various streaming media are developing rapidly. Video encoding has developed from early FLC and FL to MPEG1, MPEG2, MPEG4, RealVideo, Windows Media Video, H.264, etc.; audio encoding has developed from PCM to MP3, OGG, MPC, mp3Pro, RealAudio, APE, and Windows Media Audio, etc.; and the packaging formats of streaming media are also varied, such as AVI, MPG, RM, RMVB, OGM, MKV, WMV, etc. It is foreseeable that more formats will appear in the future. Now, many embedded players can decode and play some of these formats, so that users can watch movies in these formats on their TVs. [0003] However, due to the diversification and rapid development of streaming media...
