Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is elaborated.
The invention discloses the method and the device of loading additional information on network camera device terminal display image, described additional information can be the web advertisement, real-time news, information such as instant message or notice.
As shown in Figure 1, described network camera device comprises: camera 100, image coding module 101, network process module 102, control module 103 and character library and form modular converter 104.
Wherein, camera 100 is as source video sequence, directly the output digital video signal;
Image processing module 101 is used for the function such as reception, video image format conversion, additional information stack, MPEG-4 encoding compression of digital video image signal;
Network process module 102 comprises that two functions (1) are used for obtaining from the Internet required additional information; (2) according to appropriate protocol real-time being sent on the network of MPEG-4 code stream;
Control module 103, reception and processing come from the control command of browser on the network, and parameter, user management and the authentication of IPCamera are set;
Character library and form modular converter 104, if the content of additional information is a literal, be used for corresponding text conversion is become 101 stacks of yuv format character image input picture processing module, if the content of additional information is an image, at first described image transitions is become the yuv format data, stack in the input picture processing module 101 again;
Network process module 102 obtains additional information from the outside among the present invention, and described additional information can be fixedly to deposit in the control module 103, also can be in the Internet server.
When the user sends video request by browser, send video request to control module 103 by network process module 102, control module 103 is to the camera 100 beginning video capture of giving an order, image processing module 101 obtains from the source video image of camera input, described source video image can be an arbitrary format, carry out format conversion by 101 pairs of described sources of image processing module video image, convert the image of yuv format to.
Simultaneously, control module 103 on self or the Internet additional information server 105, the additional information that acquisition will be play; These additional informations are analyzed, if the content of these additional informations is literal, then corresponding text conversion is become in the yuv format character image input picture processing module 101 in character library and form modular converter 104, superpose with the described source video image that has converted yuv format to, additional information is added on the top or bottom navigation bar of image, and the back image that superposes carried out the compressed encoding of MPEG-4 form, last compressed MPEG-4 format-pattern is presented on the browser by network process module 102 outputs.
If these additional informations itself are exactly pictorial information, the form that then only need change pictorial information is the yuv format data, then with in this yuv data input picture processing module 101, superpose with the described source video image that has converted yuv format to, additional information is added on the top or bottom navigation bar of image, and the back image that superposes carried out the compressed encoding of MPEG-4 form, last compressed MPEG-4 format-pattern is presented on the browser by network process module 102 outputs.
Leave in the control module 103 of network camera device for the information that requires to add actually or deposit in the Internet additional information server 105, can be according to the function decision of described additional information.If what play is the additional information of immobilized substance, then can save the bandwidth of access web server like this being placed on the control module 103, cause the information category play single but do like this; If what play is renewable additional information, then need provide these information by the Internet additional information server 105.
On the browser display image method concrete steps of loading additional information as shown in Figure 2,
Step 1, from browser described network camera device is sent the capture video image request by the user;
When the user sends video request by browser, by network process module 102 video request is sent to control module 103, send instruction beginning video capture by control module 103 to camera.
Step 2, image processing module 101 obtain the view data that photograph this moment from camera 100;
Camera 100 with photographic images with the data flow transmission of arbitrary format to image processing module 101, carry out format conversion by 101 pairs of input pictures of image processing module, the unified yuv format data that convert to.
The position that step 3, judgement additional information are deposited;
(1) if additional information leaves on the control module 103, then image processing module 101 directly obtains the information content that will play;
(2) if additional information leaves on the Internet additional information server 105, then obtain information content by network process module 102 access internet additional information servers 105, input control module 103 again.
Step 4, image processing module 101 the additional information image overlay in the video output image, and output compression back MPEG-4 image;
(1) if the content of additional information is a literal, then from character library and form modular converter 104, call corresponding yuv format character image, and in the input picture processing module 101, superpose with the rear video of conversion described in step 2 data, additional information is added on the top or bottom navigation bar of image, the back view data that will superpose is carried out the compression of MPEG-4 form, at last compressed view data is exported by network process module 102, is presented on the browser;
(2) if additional information itself is exactly a pictorial information, then described pictorial information can be directly changed into the yuv format data in image processing module 101, and superpose with the described source video data that has converted yuv format to, additional information is added on the top or bottom navigation bar of image, the back image that superposes is carried out the compressed encoding of MPEG-4 form, last compressed MPEG-4 format-pattern is presented on the browser by network process module 102 outputs.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
