Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of method of transmitting video data and device.
Background technology
At present, flourish along with mobile communication technology, the disposal ability of mobile terminal and mobile network's transmission bandwidth have all obtained great lifting, become possibility thereby make to carry out real-time visual video data communication between multiple mobile terminals.Meanwhile, based on the incomparable flexibility of mobile terminal and portability, realized the target of carrying out anywhere or anytime real-time visual video data communication.
Fig. 1 is according to the schematic diagram that carries out real-time visual video data communication between multiple mobile terminals of correlation technique, as shown in Figure 1, the first mobile terminal 10 and the second mobile terminal 20 are realized real-time visual video data communication via transfer server, and wherein the first mobile terminal 10 and the second mobile terminal 20 are for completing the tasks such as video data acquiring, video data encoding, video data transmitting, video data decoding and video data playback.For example, the first mobile terminal 10 carries out video data acquiring by the camera 101 (this camera 101 both can built-in also can be external) of self, and by the coding video data of collection and send to transfer server, simultaneously, the video data of the second mobile terminal 20 from transfer server receives this coding, decodes and is shown to user it.
In Fig. 1, transfer server 30 is mainly used in video data and forwards control.For example, consider and need in diverse network (such as the Internet, local area network (LAN)), ensure service quality (Qualityof Service, referred to as QoS), the forwarding control of transfer server 30 at least needs to comprise the several operations of execution:
(1) video data sequences is divided into picture frame, and be further divided into macro block, wherein macro block is the basic element of video data sequences, it can be defined as arbitrary shape, in present video data encoding, great majority adopt the square block of 16*16 as a macro block, and picture frame is the Basic Transmission Unit that prior art adopts;
(2) thus picture frame is shone upon and makes between picture frame associated with each otherly, and macro block coefficient is converted;
(3) coding unit adopts video data QoS algorithm to the processing of encoding of the view data of video data stream.Wherein, this video data QoS algorithm generally comprises video data encoding, adaptive video data encoding, transcoding technology, code stream handoff technique of minimum transfer etc.Particularly, the video data encoding of minimum transfer refers to that producing stream of video data according to minimum acceptable bandwidth by encoder transmits, and the shortcoming of this algorithm is can not the dynamic change of flexible adaptation network; Adaptive video data encoding refers to the parameter of automatically adjusting encoder according to the variation of network environment, makes the code check of output code flow adapt to network change; Transcoding technology refers to preserves enough good compressed video datas of a quality in transfer server 30, and in the time that needs reduce bit rate output, 30 need of transfer server carry out decoding and the coding of part just can export suitable video data stream; Code stream handoff technique refers to multiple copies of the different quality of preserving same video data program in transfer server 30, the intracoded frame of these code streams is alignd, and transfer server 30 selects a suitable code stream to send to user according to user network bandwidth situation.
What as can be seen here, Fig. 1 proposed is to ensure service quality as much as possible by the forwarding control of transfer server 30.But, network condition at the second mobile terminal 20 is not good, the transmission channel that is recipient cannot give under the prerequisite of any guarantee its transmission quality, the various video data QoS algorithms that the forwarding control of above-mentioned transfer server 30 is used have all lost meaning, probably cause video data transmitting of low quality, cannot carry out video data communication even at all.
