Certainly, above-mentioned is that to have ordered visual telephone data content transmission business with caller be the explanation that example is carried out, but should be understood that, the embodiment of the invention also can be applied to the called situation of ordering visual telephone data content transmission business, only, be to replace the called video content that sends to caller.
Below in conjunction with concrete networking structure the embodiment of the invention is further elaborated.
The detailed process of the method for the embodiment of the invention specifically comprises:
Terminal 1 is initiated the video call request, and video call request process wireless network (Node B, RNC) routes the call to the MSS under the terminal 1;
MSS under the terminal 1 is to the user profile of attaching position register (HLR) inquiry terminal 1 and terminal 2;
Ordered the visual telephone data content transmission when professional in terminal 1 or terminal 2, the MSS under the terminal 1 increases preamble (as: 17003 etc.) before the call number of terminal 1, the video call request is routed to the data content transmission system;
The data content transmission system sets up video phone call through MSS and terminal 2 under the terminal 2;
Terminal 2 sends visual telephone to the data content transmission system and sets up successful affirmation message;
The data content transmission system sends visual telephone to terminal 1 and sets up successful affirmation message;
The visual telephone code stream that the data content transmission system sends by media gateway receiving terminal 1;
The data content transmission system requires to carry out transcoding with content-data to be sent according to the visual telephone code stream, and sends to terminal 2 by media gateway after the visual telephone code stream that receives replaced to the code stream that transcoding obtains;
After receiving the internet content of transcoding and using code stream, terminal 2 decodings obtain content-data to be sent and show.
In the specific embodiment of the invention, the transcoding module is converted to the TS stream format of video with content-data to be sent, also needs to carry out rate adapted simultaneously; Be connected with the multiplexing subsystem of video-telephone system and replace sending module, the TS that is converted to is spread into the multiplexing subsystem of visual telephone, the multiplexing subsystem of visual telephone is multiplexed into the visual telephone code stream together and transmits in the mobile network.
Mobile video telephone is based on H.324M agreement of ITU, and multiplexing subsystem wherein is multiplexed into single output code flow based on video code flow, audio code stream, data message and the control information etc. that utilize logic channel to represent after H.223 agreement will be encoded.And the TS stream (comprising video code flow, audio code stream, data message and control information) of replacing the video that sending module will be converted to content-data to be sent is placed in the buffer memory, multiplexing subsystem to the content in the buffer according to transmission rate, carry out rate adapted, and write in the logic channel of video code flow and speech code stream correspondence, form single code stream.
Certainly, receiving terminal is distinguished for convenience, for this TS code stream is provided with a beginning flag (as 00FF) and an end mark (as: FF00).After terminal is received, code stream is resolved into various multimedia code streams, and generate complete web page files, send browser display based on HTML according to beginning flag and end mark.
Certainly, should be understood that, in the specific embodiment of the invention, also administration module can be set in the data content transmission system, rights management, Content Management, the user individual be responsible for the user are set, and are in charge of other subsystem collaborative work.
For example the application of the embodiment of the invention is elaborated below.
Suppose that user A and user B are undertaken in the process of video calling by data transmission system, user A need send a picture to user B, then user A (also selectes picture waiting for transmission as insert the data content transmission system by the Internet by variety of way notification data content transmission system content-data to be transmitted, perhaps upload picture waiting for transmission in real time to the data content transmission system), by data transmission system this picture is required to encode according to the visual telephone code stream then, obtain the second visual telephone code stream, and the video flowing that the A that receives of the replacement of using sends sends to user B, user B can obtain the selected picture to be transmitted of user A by decoding, has realized utilizing the transmission of the content-data that visual telephone carries out.
The content of above-mentioned transmission can also be the content that called needs send to caller, illustrates as follows.
In some service process, as product introduction, suppose that user A and user B are undertaken in the process of video calling by data transmission system, user B need represent some content to user A, and (FLASH as product introduces, the Web page, the picture of product or the character introduction of product etc.), then user B is (also selected as insert the data content transmission system by the Internet by variety of way notification data content transmission system content-data to be transmitted, perhaps upload to the data content transmission system in real time), by data transmission system this content-data is required to encode according to the visual telephone code stream then, obtain the second visual telephone code stream, and the video flowing that the B that receives of the replacement of using sends sends to user A, user A can obtain the selected picture to be transmitted of user B by decoding, has realized utilizing the transmission of the content-data that visual telephone carries out.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
