Embodiment
The present invention realizes that by in application layer data being split multichannel nation is fixed.
As shown in Figure 1, be network parallel data transmission method flow chart of the present invention, comprise:
The data based unique characteristics that step 1, data receiver will need to transmit is split as at least two group data;
At least two communication ports that step 2, data receiver utilization have been set up transmit this at least two groups data to the data receiver;
Step 3, data receiver merge the two group data that receive at least.
Owing to be data to be split in the feature of application layer according to data, therefore can effectively avoid carrying out the fixed defective of passage nation at protocol layer, there is not the total bandwidth loss after bandwidth is bound.
Data receiver needs at least two networking communication modules.Before carrying out transfer of data, data receiver and data receiver utilize its networking communication module to set up communication port, for example, set up a communication port by each networking communication module.Each communication port can be identical for type, for example, is the GPRS passage, also can be that type is different, and for example, two is the GPRS passage, and one is the ADSL passage.Data receiver need be notified the recipient with the address information of a plurality of communication channels, when data receiver is in narrowband network, when the data receiver is in broadband network, data receiver need utilize a plurality of narrow band communication channels to carry out the transmission of data, promptly data receiver by a plurality of transmissions address to data receiver's address transmission data; When the data receiver is in narrowband network, when data receiver was in broadband network, the data receiver also can receive the data of sending from an address by a plurality of addresses; When the both sides of transfer of data all are in narrowband network, a plurality of address transfer data of a plurality of addresses of data receiver to the data receiver are arranged.For the ease of the recipient merging of data is handled, when transmit leg has a plurality of address, need will these a plurality of addresses information notify the recipient.
For the transmission of needs coding, the data after data receiver will split are encoded and are transmitted.
Fractionation for data can have multiple mode, as long as this data resolution method is reversible.When splitting, can utilize the feature of data structure self.For example, the data of transmission are stereo audio signal, can cut apart according to left and right acoustic channels so; The data of transmission are video image, image can be split into N * M grid so, form NM sub-video, also but interlacing is cut apart, is cut apart according to the color space feature, with RGB is example, cuts apart according to the RGB different colours, according to nbit before each figure layer of RGB, back (8-n) bit is cut apart, and perhaps cuts according to the order between the different frame.For various data formats, give a reversible partitioning scheme cutting data and get final product in a word, available partitioning scheme combination is various, does not enumerate one by one at this.
When the transmission data, can be seen as relatively independent data to these data sets, respectively transmission.For example, for NM sub-video, these sub-videos are compressed into independently video flowing respectively by the individual independently compressor reducer of NM.Again with these independently video flowing by NM independently networking passage (can be the device that the arrowband connects) send to data receiver.Data receiver can be transmitted one group of data on each communication port when sending data, for example, view data is divided into three groups of R, G, B, utilizes three communication ports to transmit three groups of data respectively; Also can organize data characteristic according to each, as data volume, utilize a communication port transmission multi-group data, for example, when vedio data is represented with yuv format, data are divided into three groups according to Y, U, V, the data volume of three groups of data ratio is 4: 1: 1 so, so, traffic channel Y group data be can utilize, another traffic channel U group data and V group data utilized.In addition, in a plurality of communication channel types of setting up not simultaneously, can not take all factors into consideration, for example each data volume and Channel Transmission ability yet, utilize the bigger Channel Transmission Y group data of bandwidth, and utilize two little channels of bandwidth to transmit U group data and V group data respectively.
The data receiver, need the multi-group data that receive be merged according to the fractionation mode, if data receiver is encoded to data, the recipient wants earlier the data of respectively organizing that receive independently to be decoded so, and then the decoded data of respectively organizing are merged.The both sides of transfer of data can appoint in advance that the data of concrete application split mode; Also can arrange multiple fractionation mode in advance, and define the code of every kind of fractionation mode correspondence, in transfer of data, transmit leg is notified the recipient the concrete fractionation mode that adopts by sending respective code then.Also can in every group of data, add and merge reference information, for example, in the sub video stream that splits according to the position, add the positional information of sub-video, carry out the merging of image by this positional information.When data were video image, synchronous signal transmission regularly also was so that the data receiver is to the broadcast of video.The data receiver just can utilize these data after carrying out the data merging, or these data are continued to send and the third party.
As shown in Figure 2, for the present invention with the specific embodiment flow chart.In the present embodiment, data receiver is in narrowband network, the data receiver is in broadband network, where transmit leg splits into N * M grid with image according to prevailing video wall mode is several, form NM sub-video, to reciever, reciever merges view data and plays according to splitting type by identical NM the traffic channel of type.Present embodiment specifically comprises the steps:
Where step 102, data receiver split into N * M grid with video image according to prevailing video wall mode is several, form NM sub-video;
The present invention has realized not changing the arrowband connection device, does not change ISP and is provided with, and on basis, original networking, a plurality of passages is bound fully, and is not had the total bandwidth after the bandwidth binding to lose; This method transplantability is good, and Internet protocol and connection mode are not had dependence, can use on any networking type of attachment, the bandwidth of existing narrow band transmission can be doubled, to reach it because of the bandwidth constraints function that is beyond one's reach; This method is applicable to the various data structures that have reversible method for splitting.
