Problems solved by technology
[0005] through the aforementioned figure 1 It can be found that the practice of the known technology has the following defects: first, the user computer must be connected to the conference management device at the local end through a data connection. In general, due to the distance between the conference management device and the user computer Not fixed, and the number of user computers 101 may be more than one, these data connections will make the conference space appear messy and inconvenient to operate; secondly, the conference management device must simultaneously shoulder the responsibility of compressing the communication screen format, compressing the screen, and converting the network transmission format and other work, making the conference management device overloaded and unable to achieve efficient video conferencing process

Embodiment Construction
[0067] In the known technology, the conference management device must simultaneously undertake tasks such as compressing the communication screen format, compressing the screen, and converting the network transmission format. In order to improve the transmission effect and reduce the burden on the conference management device, the present invention converts the image screen into a video data screen Distributing the actions to a single video provider provides a more efficient method of image data transfer.
[0068] See figure 2 , which is a schematic diagram of the system architecture applied by the present invention. In the present invention, the video transmission steps between the remote conference management device and the local conference management device are defined as follows: first, the video data providing device 201 (for example: a personal computer, a mobile electronic device, a camera device or an image extraction device, etc.) through the local conference managem...

The invention relates to a method, a system and a device for transmitting video data. The method for transmitting the video data is applied among a video data providing device, a first video device and a second video device. In the method, the video data providing device obtains an picture coding format supported by the first video device; the video data providing device provides a picture, converts the picture into video data according to the picture coding format and transmits the video data to the second video device; and the second video device transmits the video data to the first video device, and the first video device decodes the video data according to the picture coding format to obtain the picture back. The invention really improves the phenomenon of overweight load because compression and transmission mechanisms are both arranged in a conference management device in the known technology, thereby further improving the effect of data transmission in a video conference.
Description
technical field [0001] The present invention relates to a method, system and device for video data transmission, in particular to a method for obtaining and converting an image encoding format using a video data providing device. Background technique [0002] In recent years, video conferencing has become a frequently used tool in the busy business world. The use of video conferencing not only avoids the need for participants to travel to and fro, but also makes meetings more immediate and efficient. When the video conference is being transmitted, in addition to the surrounding environment of the venue, the images to be transmitted also need to transmit the file data and operation screens used in the conference, such as displaying the contents of the computer screen and electronic whiteboard through the network in real time. Transmission, so the amount of transmitted data is also very important for network transmission with heavy video bandwidth. [0003] In other words, th...
