摘要：本发明公开了一种转换视频编码的方法，将第一编码方式的视频帧解码为标准中间格式的图像，同时识别该视频帧是基准帧还是预测帧并记录识别结果；根据所记录的识别结果，将该标准中间格式图像编码为第二编码方式的视频帧。本发明还公开了使用该方法的视频编码转换设备。应用了本发明的转换视频编码的方法和设备，可以在进行视频编码转换时，根据原编码方式的视频帧的类型进行重新编码，避免将原编码方式的大量预测帧重新编码为新编码方式的基准帧所导致的图像误差，从而提高了重编码之后视频图像的质量。

摘要： A method and apparatus for transmitting and receiving background noise and a silence compressing system. Classifying the background noise into different categories based on the noise character, establishing correspondence between noise character and noise categories, setting different background noise categories correspond to different silence insertion descriptors(SID) frame structures. The transmitting end confirms the category of current background noise based on the noise character and established correspondence between noise character and noise categories, generates silence insertion descriptors(SID) frame based on the frame structure correspond to the noise category, and transmits the silence insertion descriptors(SID) frame. Because adopting SID frames with different structures to describe background noise with different noise character, the character of various background noise can be accurately described, the comfort background noise synthesized by decoding end can well matches the background noise character of coding end, and enhanced quality of synthesized voice can be achieved.

摘要：一种IP分组网络间的数据传输方法及网关及系统，包括：在分组网络边缘的网关直接将其映射至时分复用TDM线路，透传给TDM线路中属于另一个分组网络的对端边缘网关，对端边缘网关直接将映射数据转换为原数据包，发给与其相连的分组网络。这样，在由TDM连接的多个分组网络中，可以在各个分组网络间直接映射透传传真数据包，无需对数据进行反复的调制和解调，有效地节省了网关的处理能力，降低了在数据传输过程中出错的概率，减少由反复进行调制、解调而引入的时延，提高传真的成功率和可靠性。

摘要： A control method, device, and system of an echo canceller during faxing, the method comprises: a signal detecting device enables an echo canceller after a trigger signal is detected, if the echo canceller is in a turn-off state. A signal detecting unit detecting signals in the fax system is arranged in the device and the system, which enables the turned-off echo canceller after the trigger signal is sent, such that the turn-off echo canceller could be turned on again during the faxing process, and the reliability of the fax and the quality of the fax image are ensured.

摘要： A method and system for negotiating about the ability of the data signal detector, include that at the time of the voice band data transferring, the gateway at the transmission end transmits the first signaling which includes the information of the ability supported by the data signal detector (301); after the gateway at the receiving end according to the first signaling received identifies whether the gateway at the transmission end has transmitted the data according to including the data detector, and decides if starting the non-voice decoder to decode the soundless packet (302). Farther, when the gateway at the receiving end can not startthe non-voice decoder, it feeds back the second signaling which includes the information of the ability supported by the data signal detector to the gateway at the transmission end (303); the gateway at the transmission end according to the second signaling received transmits data by the mode which does not include the data signal detector (304). The present invention is used in the fax service of packet network, the ability of the data signal detector can be negotiated at the time of transferring by the voice band data. The present invention is also discloses a gateway at the transmission end, a gateway at the receiving end which can negotiate about the ability of the data signal detector.

摘要： A method for realizing data service in a voice band data manner comprises the following steps: a. a data signal detector divides the input signal frames into data signal frames and non-data signal frames, then a voice coder proceeds a voice coding on the data signal frames, while the non-voice coder proceeds a mute compression coding on the non-data signal frames; b. a voice decoder proceeds a voice decoding on the data signal frames which are voice coded to output available dada signals, while a non-voice decoder proceeds a decoding on the non-data signal frames which are mute compression coded to reconstruct mute signals. A system and a signal detector use this method.
