Method of device discovery and digital television terminal

Abstract

The embodiment of the invention discloses a method of device discovery and a digital television terminal. The method comprises the following steps: generating a two-dimension code comprising device identification information by the digital television terminal, wherein the device identification information is information capable of identifying the digital television terminal; displaying the two-dimension code generated by the digital television terminal on a display interface for user interaction to allow a mobile terminal to acquire the two-dimension code and build relationship with the digital television terminal through the two-dimension code. Through the adoption of the method and the digital television terminal, the two-dimension code can be generated through the digital television terminal to realize multi-screen interactive business, so as to guarantee the reliability of the device discovery.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device discovery method and a digital television terminal. Background technique [0002] In multi-screen interactive services, mobile terminals such as mobile phones and tablet computers can interact with devices such as digital TV terminals. Prior to this, mobile terminals need to discover digital TV terminals, so device discovery is the basis of multi-screen interaction. Speed ​​and reliability directly affect the experience of multi-screen interaction. If the device is not found, it may directly cause the failure of multi-screen interactive experience or make it difficult to promote the business. [0003] In the prior art, the multicast network technology is used for device discovery to obtain the IP (Internet Protocol, Internet Association) address and service port number of the digital TV terminal. The multicast network device needs a device gateway to be discovered...

[0002] In multi-screen interactive services, mobile terminals such as mobile phones and tablet computers can interact with devices such as digital TV terminals. Prior to this, mobile terminals need to discover digital TV terminals, so device discovery is the basis of multi-screen interaction. The speed and reliability directly affect the experience of multi-screen interaction. If the device is not found, it may directly cause the failure of the multi-screen interactive experience or make it difficult to promote the business.

[0003] In the prior art, the multicast network technology is used for device discovery to obtain the IP (Internet Protocol, Internet Association) address and service port number of the digital TV terminal. The multicast network device needs a device gateway to be discovered, and when there is When there are multiple digital TV terminals, it is not easy to distinguish which digital TV terminal the discovered IP address corresponds to, which may lead to wrong device connection, which affects the reliability of device discovery and the user experience of multi-screen interactive services.
