Description of the Invention: [Technical Field] The present invention relates to a multimedia transmission system and method thereof, and more particularly to a multimedia transmission system for a near-end network and a method thereof. [Prior Art] At present, instant messaging (IM) is a very common Internet application, such as Windows Live Messenger and Skype. Internet users who install IM can establish each other through IM. In the videoconferencing session, each user must individually set up the camera, microphone, and microphone used for the video conferencing function before setting up the video conference. However, after the video conference is established, it is no longer possible to dynamically select other cameras or voices. Input and output device. The handheld bluetooth voice device can establish a Bluetooth connection between the personal computer and the handheld Bluetooth voice device through setting, and the special sound card with the handheld Bluetooth voice device can be used to broadcast the personal computer on the personal computer. The sound is directed to the handheld Bluetooth voice device, which is then played by the handheld Bluetooth voice device. Therefore, after the voice conference is established, the user can first establish a Bluetooth connection between the personal computer and the handheld Bluetooth voice device, and then ask the application to direct the voice to the handheld Bluetooth voice device, so that the user can keep the voice. In the case of the meeting, hold the handheld Bluetooth device to continue talking to other places. However, the above system can only be used in voice conferences and cannot be used in video conferencing, and the system requires special Bluetooth voice devices and special sound cards. 201121325 Therefore, the present invention provides a multimedia transmission system and a method thereof, which can enable a user to dynamically transfer a video conference in progress of an electronic device to another electronic device without re-establishing video, and the present invention is not limited to The special electronic device, for example, the original user uses the desktop machine to establish a video conference with the remote end, and the system of the present invention can dynamically display the video to the notebook computer or various handheld multimedia devices.

The image data is 44〇 encoded, and the first:::Γ1420 two Γ sound is formed! 1 input unit 221 丨 1 丨 system draws the fifth sound;; 201121325 2211 ° second audio operation device 2210 is a microphone, The second audio encoder 441 is used to encode the fifth audio data 441 by the second audio encoder 441 to form a third audio data 42. The second network module 23 is connected to the first network module 14 by the network.连^ ^ ^ receives the second multimedia material 41 in the first communication protocol, and then transmits it to the multimedia one-out module 21, and at the same time After receiving the third multimedia material 41, the third multimedia data μ is sent to the network module 14 by using the first communication protocol, and the second control module 24 is connected to the second network module. The first multimedia output module 21, the second display module 2, and the second multimedia input module 22 provide a second user interface and control the second command 2_ The transmission of the multimedia data 41, the multimedia data 43, the fifth multimedia data 42, and the sixth multimedia data 45. The second command 24 is the first control second control module 24 riding multimedia transmission Instructions. " 凊 Refer to Fig. 2, which is a flow of the multimedia transmission method of the present invention. The multimedia transmission method of the present invention comprises the following steps (S1) for receiving and providing at least one remote transmission φ by the first device. At least the first multimedia device, the first device includes a first multimedia output module, a storage module, and a first display module, and the at least one first data includes at least a first image data and at least a first audio output module, wherein the first multimedia output module captures and encodes at least one first audio material in a dynamic link library stored in the first storage module to form a second audio data; (S3) the first multimedia output module reads and encodes the at least one first image data displayed on the first display module to form a second image data; (S4) the first device transmits the first communication protocol 12 201121325 Sending a second multimedia material including the second audio data and the second image data to a second device, wherein the second device is connected to the first device by a network; (S5) the second device is configured by the first communication protocol Transfer of the third multimedia Through - means; and (S6) a first means to a second communication protocol developed ^ three multimedia information to at least one of the distal end. The details of each device and module are as described above, and will not be described here. With the multimedia transmission system and method of the present invention, local users can perform video conferencing without having to be fixed in front of a desktop computer or a notebook computer, and can be used by various local networks such as a wired network. , wireless network or Bluetooth network 'connects the mobile multimedia device to the desktop computer or the notebook computer, and then 'bidirectionally transmits the multimedia data of the video conference for the mobile video conference 4, and the multimedia transmission method of the present invention can be There are many ways to apply performance and flexibility to multiple videoconferencing. The above description is for illustrative purposes only and not as a limitation. Any changes or modifications to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
