Embodiment
The embodiments of the invention provide a kind of transmission method of image and system, below in conjunction with accompanying drawing, to of the invention real
Example is applied to be described in detail.Referring to Fig. 6, the system includes video sending end and more than one video receiver, wherein, video
Transmitting terminal broadcasting video data by the way of broadcast, the video data is multiframe image data.Wherein, video receiver can
For television set, notebook computer, mobile phone and PAD etc..The system will be described in detail later.
As shown in figure 1, the image transfer method that the present invention is provided comprises the following steps：
Step 10：Screen picture is divided into major part and secondary part by video sending end, wherein it is possible to by screen map
As being divided into the left and right, part of upper, middle and lower five and being cached, wherein, the center section of screen can be major part, other
Four parts are secondary part, shown in Figure 2.
It is understood that, it would however also be possible to employ other image partition methods, for example：Extend column border line, screen-picture is carried out
Segmentation, it is shown in Figure 3.
And for example, it can also extend row edge line and column border line simultaneously, screen-picture is split, it is shown in Figure 4.
In addition, a row edge line therein and a column border line can be extended, screen picture is split, referring to figure
Shown in 5.
Step 20：Each several part image is separately encoded by video sending end, and each several part image formed in encoded
The identifier for representing the parts of images position is added in the packet header of packet, then the packet of each several part image is broadcasted
Send.
Wherein, in the present embodiment be located at upper and lower, left and right, in five part pictures can use the mark for representing relevant position respectively
Know symbol to represent its position, to be such as indicated respectively with 000,001,010,011, the 100 of three bytes, and add corresponding picture number
According in bag.The various pieces for the image broadcasted also carry the information for representing to belong to same two field picture, are easy to recipient to recognize.
Wherein, for the major part and secondary part of image, it can be sent using different coded systems.For example, can
So that the secondary part of image is reduced into the modes such as the pixel of the part, resolution ratio using lossy coding mode, because image
Secondary part be much smaller with respect to major part by the probability that eyes of user is focused on, this mode can accelerate transmitting terminal volume
Code speed, also allows for video receiver and accelerates decoding speed.
Step 30：Each video receiver receives the packet of image major part according to attributes such as itself screens, and has
The packet of the reception secondary part of selection, and cached.
Video receiver detects the screen size of itself and resolution ratio, the decoding rate that can show etc. first.According to certainly
The screen size of body and the resolution ratio selection that can be shown receive the secondary part for being adapted to the image of itself.
For example：PAD is larger due to the length of screen, and width is smaller, according to its screen attribute, and PAD selections receive screen map
Picture it is left and right, in three parts of images, then in step 30, only selection receive major part view data bag and left and right part
Secondary part view data bag.If it can be appreciated that PAD is carried out into 90 degree of rotations, PAD is judged by its gravity sensor
The location status that screen is currently placed, i.e. current screen size length and width numerical value is exchanged, selection receive screen picture it is upper,
In, lower three parts of images.
And for example, large-size screen monitors TV is due to larger, complete suitable for the display image of screen, therefore large-size screen monitors TV can receive screen map
As major part and selection receive all secondary parts, that is, the upper and lower, left and right received, in five parts image.
For another example, mobile phone due to screen it is smaller, only selection can receive the major part of screen picture, i.e. center section image.
Step 40：Each video receiver is according to the location identifier in the packet header of reception, by the main portion of image
Point and selection receive secondary part decoded respectively after, be combined display.
It can be appreciated that in order that obtaining image combination accurately, when sending image, each image, which will be carried, to be represented to belong to by one
The information of two field picture segmentation, such as temporal information or frame identification information in video, with will not wrong frame when carrying out image combination
Combination.
In addition, in above-mentioned steps 20, when video sending end broadcasts each view data bag, image can also be carried
Attribute data, such as resolution ratio (i.e. image size), so when video receiver screen is not less than the screen size of transmitting terminal,
When it just can judge that it can receive total data according to image attribute data, then all images data are received.
As shown in fig. 6, image delivering system provided by the present invention, including video sending end 61 and at least one video connect
Receiving end 62, wherein,
The video sending end 61 includes：
Image segmentation module 611, for the image to be sent of video sending end 61 to be divided into major part and at least
One secondary part；
