Following embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
Embodiment
As shown in Figure 1, be the running environment figure that the present invention is based on the shared Streaming Media transfer system preferred embodiment of desktop.Streaming Media transfer system 10 runs in the server 1, and this server 1 is connected at least one client 2, and the Streaming Media of playing on the desktop (not shown) of said Streaming Media transfer system 10 with server 1 sends client 2 to.This Streaming Media comprises audio stream, video flowing, animation streams etc., and this Streaming Media just may be displayed on after need decoding on the desktop of desktop and client 2 of server 1.Said client 2 has decompressing function.
As shown in Figure 2, be the functional block diagram of Streaming Media transfer system 10 among Fig. 1.Said Streaming Media transfer system 10 comprises: receiver module 100, opening module 101, judge module 102, first sending module 103, first control module 104, interception module 105, second sending module 106 and second control module 107.Said module is the software program section with specific function; This software program section is stored in computer-readable recording medium or other memory device; Can be carried out by computer or other calculation element that comprises processor, thereby accomplish the work flow that transmits Streaming Media among the present invention.
When judged result is a said client 2 when having the decoding capability of said initial flow medium, first sending module 103 is used for these initial flow medium are sent to client 2.
When above-mentioned judged result is a said client 2 when not having the decoding capability of said initial flow medium, interception module 105 be used for playing on the desktop of intercepting server 1 with the corresponding picture of said Streaming Media, and the picture of this intercepting is compressed into compressed package.
The compressed package that second control module 107 is used to control 2 pairs of these receptions of said client decompresses, and plays the picture after this decompression.
As shown in Figure 3, be the operation process chart that the present invention is based on the shared Streaming Media transfer approach preferred embodiment of desktop.
