Cross network sharing system

A system, comprising:

• a common display;
• a display computer to run collaboration software connected to the common display that drives the common display, the display computer being on a first network;
• a first mobile device to run a streaming application, the first mobile device being on the first network, the streaming application to convert a display of the first mobile device into stream data;
• a second mobile device to run a sharing application and the streaming application, the second mobile device being on a second network, separate from the first network, the streaming application to convert a display of the second mobile device into stream data;
• a control channel between the second mobile device and the display computer;
• a first stream channel between the display computer and the first mobile device;
• and
• a second stream channel between the display computer and the second mobile devices, wherein
• the first and second mobile devices send stream data to the display computer through corresponding stream channels,
• the second mobile device sends control data to the display computer, and
• the display computer is to display the stream data from the first and second mobile devices on the common display.

A system, comprising:

• a common display;
• a display computer to run collaboration software connected to the common display that drives the common display, the display computer being on a first network;
• a first mobile device to run a sharing application and a streaming application, the first mobile device being on a second network, separate from the first network, the streaming application to convert a display of the mobile device into stream data;
• and
• a relay server in communication with the first mobile device and the display computer, wherein, when the first mobile device is to be connected to the display computer to stream content from the first mobile device to the display computer to be displayed on the common display, the sharing application on the first mobile device is to send a key associated with the display computer to the relay server, and the relay server is:
• to determine the associated display computer in the first network based on the key, and
• to establish a control channel, and
• a stream channel between the display computer and the mobile device to supply the display computer with the stream data from the mobile device, wherein the display computer is to display the stream data on the common display.

• a control channel between the mobile device and the display computer;
• and
• a stream channel between the display computer and the mobile device and wherein the mobile device sends encrypted stream data to the display computer, wherein the display computer is to decrypt the encrypted stream data and display the stream data on the common display.
