Information processing and content transmission for multi-display
Processing methods and systems for multi-display. The implementations may include establishing, by a computing device, a connection between a controlling terminal and an accessory display device. The computing device may receive activity ID information of a current presentation from the controlling terminal using the established connection, establish a mapping between the current presentation and the accessory display device based on the activity ID information, and transmit a presentation content associated with the current presentation to the accessory display device for display based on the mapping.
1. A method implemented by a computing device, the method comprising:
establishing a connection with a server terminal;
initializing a presentation associated with the connection;
assigning unique activity ID information to the presentation;
transmitting the activity ID information to the server terminal;
transmitting a request for establishing a mapping with an accessory display device to the server terminal, transmitting the request comprising:
receiving a ID code of the accessory display device; and
transmitting the request for establishing the mapping with the accessory display device corresponding to the ID code to the server terminal; and
transmitting a controlling signal of the presentation and a presentation content to the server terminal, wherein receiving the ID code of the accessory display device comprises:
receiving the ID code of the accessory display device issued by the server terminal;
scanning a two-dimensional ID code displayed by the accessory display device;
receiving a user input including the ID code of the accessory display device; or
receiving the ID code of the accessory display device via a sound wave.
2. The method of claim 1 , wherein the accessory display device comprises a monitor or a television.
3. The method of claim 1 , wherein the connection comprises a persistent connection.
4. The method of claim 3 , wherein the persistent connection comprises a TCP persistent connection, a HTTP persistent connection, or a socket persistent connection.
5. The method of claim 1 , wherein the activity ID information is generated using the presentation content.
6. The method of claim 1 , wherein the activity ID information comprises a title of the presentation content, related information of the presentation content or a set of numbers randomly generated based on the presentation content.
7. The method of claim 1 , wherein the controlling signal comprises a signal associated with one or more presentation gestures and/or actions corresponding to the presentation content.
8. One or more computer-readable media storing executable instructions that, when executed by one or more processors of a computing device, cause the one or more processors to perform acts comprising:
establishing a connection with a server terminal;
initializing a presentation associated with the connection;
assigning unique activity ID information to the presentation;
transmitting the activity ID information to the server terminal;
transmitting a request for establishing a mapping with an accessory display device to the server terminal, transmitting the request comprising:
receiving a ID code of the accessory display device; and
transmitting the request for establishing the mapping with the accessory display device corresponding to the ID code to the server terminal; and
transmitting a controlling signal of the presentation and a presentation content to the server terminal, wherein receiving the ID code of the accessory display device comprises:
receiving the ID code of the accessory display device issued by the server terminal;
scanning a two-dimensional ID code displayed by the accessory display device;
receiving a user input including the ID code of the accessory display device; or
receiving the ID code of the accessory display device via a sound wave.
9. The one or more computer-readable media of claim 8 , wherein the accessory display device comprises a monitor or a television.
10. The one or more computer-readable media of claim 8 , wherein the connection comprises a persistent connection.
11. The one or more computer-readable media of claim 10 , wherein the persistent connection comprises a TCP persistent connection, a HTTP persistent connection, or a socket persistent connection.
12. The one or more computer-readable media of claim 8 , wherein the activity ID information is generated using the presentation content.
13. The one or more computer-readable media of claim 8 , wherein the activity ID information comprises a title of the presentation content, related information of the presentation content or a set of numbers randomly generated based on the presentation content.
14. The one or more computer-readable media of claim 8 , wherein the controlling signal comprises a signal associated with one or more presentation gestures and/or actions corresponding to the presentation content.
15. A computing device comprising:
one or more processors;
memory storing executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
establishing a connection with a server terminal;
initializing a presentation associated with the connection;
assigning unique activity ID information to the presentation;
transmitting the activity ID information to the server terminal;
transmitting a request for establishing a mapping with an accessory display device to the server terminal, transmitting the request comprising:
receiving a ID code of the accessory display device; and
transmitting the request for establishing the mapping with the accessory display device corresponding to the ID code to the server terminal; and
transmitting a controlling signal of the presentation and a presentation content to the server terminal, wherein receiving the ID code of the accessory display device comprises:
receiving the ID code of the accessory display device issued by the server terminal;
scanning a two-dimensional ID code displayed by the accessory display device;
receiving a user input including the ID code of the accessory display device; or
receiving the ID code of the accessory display device via a sound wave.
16. The computing device of claim 15 , wherein the accessory display device comprises a monitor or a television.
17. The computing device of claim 15 , wherein the connection comprises a persistent connection, the persistent connection comprising a TCP persistent connection, a HTTP persistent connection, or a socket persistent connection.
18. The computing device of claim 15 , wherein the activity ID information is generated using the presentation content.
19. The computing device of claim 15 , wherein the activity ID information comprises a title of the presentation content, related information of the presentation content or a set of numbers randomly generated based on the presentation content.
20. The computing device of claim 15 , wherein the controlling signal comprises a signal associated with one or more presentation gestures and/or actions corresponding to the presentation content.
