Abstract

The disclosed data business method based on VBD comprises: a. a data signal detector sets the energy decision threshold to compare with the signal frame energy, if signal frame energy over the threshold, determines the data frame as data signal frame to allow it enter speech coder for low-loss coding and output, or else as the non-data signal frame to allow it enter non-speech coder for static compression coding and output; and b. the receiving side sends the speech package to speech decoder to output effective data signal, or sends the static package to non-speech decoder to reconstruct the static signal. This invention reduces channel resource occupancy greatly.

Description

technical field

[0001] The present invention relates to the technical field of media stream transmission, in particular, to the technology of data stream transmission in a gateway. Background technique

[0002] The rapid development of network technology makes it possible to use packet technology to transmit multimedia. The trend of integration of traditional communication technology and packet technology is becoming more and more obvious. Due to the different encoding methods of media streams transmitted in traditional communication networks and modern packet communication networks, in The combination of the traditional network and the packet network requires a codec to convert the encoding method of the media stream, and the device that realizes this conversion is a gateway.

[0003] Currently, the media streams processed by the gateway mainly include voice streams, data streams, and video streams. The data stream mainly refers to the signals sent by data devices such as ...
