Problems solved by technology

If another large-screen device is used to replace the original large-screen device, it must be re-paired with the terminal, which is not conducive to the replacement of large-screen devices
Since the terminal device transmits data to the large-screen device for display, and the data is stored on the terminal device, the data will be lost during transmission, so that problems such as frame drop and delay can be found when displaying on the large-screen device

Abstract

The invention relates to the technical field of projection, in particular to a cross-screen projection method and device for a heterogeneous network. The invention provides a cross-screen projection method for a heterogeneous network, which is applied to a server and comprises the following steps that: enabling the server to receive instruction information sent by a terminal, wherein the instruction information comprises pairing relation information and media asset content parameter information; Acquiring a set top box identifier ID corresponding to the terminal according to the pairing relation information; And sending the media asset content parameter information to the set top box according to the set top box ID, so that the set top box retrieves watching content information from the metadata end according to the media asset content parameter information, and projects the watching content information to large-screen equipment. According to the invention, data transmission loss and frame loss and delay on a large screen in the prior art can be avoided.

Description

technical field [0001] The present disclosure relates to the technical field of projection, and in particular, to a heterogeneous network cross-screen projection method and device. Background technique [0002] Content transfer, as the name implies, is to transfer data from one device to another for editing and displaying. At present, there are many technologies similar to content transfer on the market. The one that is most relevant to public life is mobile phone screen projection, which maps mobile phone content to large-screen devices. The main solution of this technology is that large-screen devices and terminal devices (mobile phones, pads, etc.) co-exist on the same network, and through the management software of the terminal, the media assets (pictures, videos, etc.) , description, control, event and presentation, and a series of processes to map the content of media assets to large-screen devices. The most important prerequisite for the implementation of the prior ...
