Finally, the smart device pushes the video stream to the video terminal by using the video session channel where the video call is in progress, so that the smart device can share the desktop content of the smart device with the video terminal.
本发明另一实施例中，与上一个实施例不同的是：由于转换智能设备的共享的桌面内容的显示数据的视频参数，可能与已经建立好的的视频通话的视频会话通道的视频参数不相同，智能设备并不利用已经建立好的视频通话的视频会话通道，而是重新与视频终端协商传输视频数据，获取新的视频参数，并建立与视频终端新的视频会话通道，后续过程的同S202至S205，这里不再赘述。在本发明实施例中，当智能设备建立与视频终端新的视频会话通道后，原先用于视频通话的视频会话通道可以被释放，也可以同时存在，这样视频终端就可以用两个视频窗口接收智能设备传输的视频流。In another embodiment of the present invention, the difference from the previous embodiment is that due to the conversion of the video parameters of the display data of the shared desktop content of the smart device, it may be different from the video parameters of the video session channel of the established video call. Similarly, the smart device does not use the video session channel of the video call that has been established, but re-negotiates with the video terminal to transmit video data, obtains new video parameters, and establishes a new video session channel with the video terminal. S202 to S205 will not be repeated here. In the embodiment of the present invention, after the smart device establishes a new video session channel with the video terminal, the video session channel originally used for the video call can be released or exist at the same time, so that the video terminal can use two video windows to receive Video streaming from smart devices.
