Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In embodiments of the present invention, transmitting terminal carries out, according to predeterminated frequency sampling, obtaining sampled speech data to audio signal; To compress control, Lossless Compression is carried out to described sampled speech data, obtain compressed voice data; Described compressed voice data are transmitted with RTP; Receiving terminal, according to the described compressed voice data received, calls the decompress(ion) control corresponding with described compression control to described compressed voice data decompression, obtains described sampled speech data.
Below in conjunction with specific embodiment, realization of the present invention is described in detail:
Embodiment one
Fig. 1 shows the realization flow of the method for the reduction voice transfer load that the embodiment of the present invention one provides, and details are as follows:
It should be noted that, lossless data compression (LosslessCompression) refers to that the data after using compression are reconstructed, or be called reduction, decompression, data after reconstruct are identical with original data, and Lossless Compression is for requiring signal and the on all four occasion of primary signal of reconstruct.That is data information after overcompression is not suffered a loss, and can also return to the former state before compression completely.
In step S101, transmitting terminal carries out, according to predeterminated frequency sampling, obtaining sampled speech data to audio signal; To compress control, Lossless Compression is carried out to described sampled speech data, obtain compressed voice data; Described compressed voice data are transmitted with RTP.
In the present embodiment, described predeterminated frequency refer to pre-set within a second to the sampling number of voice signal, the reduction of sample frequency more high sound is more true more natural, also more occupied bandwidth in sample frequency its transmitting procedure higher, the general sample frequency using 8K8bit.Described compression control is the control compressed sampled speech data, and its suffix is .rtp, namely carries out compressing the file generating .zlib to the loading section of RTP signal.RTP (Real-timeTransportProtocol, RTP) has the end-to-end transfer service of real-time characteristic for data provide, as the interactive video audio frequency under multicast or unicast network services or analogue data.
In step s 102, receiving terminal, according to the described compressed voice data received, calls the decompress(ion) control corresponding with described compression control to described compressed voice data decompression, obtains described sampled speech data.
In the present embodiment, described decompress(ion) control is control compressed voice data being carried out to decompress(ion).Described receiving terminal receives described compressed voice data, and described compressed voice data are put into buffering area, then according to the described compressed voice data received, call the decompress(ion) control corresponding with described compression control to described compressed voice data decompression, obtain described sampled speech data.Finally, described sampled speech data are sent to dsp chip parsing by described receiving terminal.The application scenarios of the reduction voice transfer load of transmitting terminal and receiving terminal as shown in Figure 2.
The present embodiment, decreases by Lossless Compression the bandwidth that voice take, simultaneously owing to playing encipherment protection to voice content.
