Description
Technical Field
The present application relates to the field of document display technologies, and in particular, to a display device and an information prompting method.
Background
The display device can provide the user with the media asset playing function, such as playing of audio, video, pictures and other resources, which is widely concerned by the user. With the development of big data and artificial intelligence, the functional requirements of users on display devices are increasing day by day. Some users want to realize multi-screen interaction during the media asset playing process. The multi-screen interaction means that the media asset content can be transmitted on different display devices, and the media asset content can be shared on different display devices at the same time. Currently, the mainstream multi-screen interaction technology is mostly based on DLNA (DIGITAL LIVING NETWORK ALLIANCE ), miracast, airPlay, google Cast and other media asset transmission technologies to realize the transmission of media asset contents.
The Google Cast transport process relies on the SSL (Secure Sockets Layer Secure Sockets) protocol. The SSL Protocol is located between a TCP (Transmission Control Protocol)/IP Protocol and various application layer protocols, and provides security support for data communication. The SSL protocol can be divided into two layers: the SSL recording Protocol (SSL Record Protocol) is established on a reliable transmission Protocol (such as TCP) and provides support for basic functions of data encapsulation, compression, encryption and the like for a higher-layer Protocol; an SSL Handshake Protocol (SSL Handshake Protocol) is established on the SSL recording Protocol, and is used for performing identity authentication, encryption algorithm negotiation, encryption key exchange, and the like on two communication parties before actual data transmission starts, where SSL Handshake failure (i.e., failure in media resource transmission) may be caused by inconsistency of system time of a multi-screen interactive display device. For example, when the user manually changes the data & time (system time) in the settings menu of one display device accidentally or with other intentions, the system time of the display device is inconsistent with the system time of other display devices, and thus the multi-screen interaction for transmission without media resources fails. At this moment, the user does not know that the multi-screen interaction fails due to the fact that the user changes the system time, and therefore a display device is urgently needed, the display device can prompt the user that the failure of the multi-screen interaction function is possibly caused by the change of the system time under the condition that the user modifies the system time, the user can be helped to find out the reason of the failure of screen projection, and the experience of the user is improved.

Some users want to realize multi-screen interaction during the media asset playing process. The multi-screen interaction means that the media asset content can be transmitted on different display devices, and the media asset content can be shared on different display devices at the same time. At present, the mainstream multi-screen interaction technology is mostly based on DLNA, miracast, airPlay, google Cast and other media asset transmission technologies to realize the transfer of media asset contents.
The Google Cast transport process relies on the SSL (Secure Sockets Layer Secure Sockets) protocol. The SSL protocol is positioned between the TCP/IP protocol and various application layer protocols and provides safety support for data communication. The SSL protocol can be divided into two layers: the SSL recording protocol is established on a reliable transmission protocol and provides support for basic functions of data encapsulation, compression, encryption and the like for a high-level protocol; the SSL handshake protocol is established on the SSL record protocol and used for carrying out identity authentication, encryption algorithm negotiation, encryption key exchange and the like on two communication parties before actual data transmission starts, and SSL handshake failure can be caused by inconsistent system time of the multi-screen interactive display equipment.
