Embodiments of the invention disclose a display system, a method for decoding device hot backup in the display system and a backup decoding device. The display system comprises N display devices, N work decoding devices and M backup decoding devices, wherein N and M are positive integers; the N work decoding devices are respectively connected with the N display devices; and each backup decoding device is connected with each of the N display devices, and is used for carrying out hot backup for the N work decoding devices, judging whether the backup decoding equipment is switched from a backup state to a work state according to the state and priority information of the backup decoding equipment and the states and priority information of the other backup decoding devices when any work decoding device is abnormal, and outputting a video signal to the display device corresponding to the abnormal work decoding equipment. In the scheme, any abnormal work decoding device can be replaced by all the backup decoding devices, so that the fault interrupt time of the display businesses can be shortened and the backup success rate is relatively high.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display system, a method for hot backup of a decoding device, and a backup decoding device. Background technique [0002] In the existing decoding and display system with multiple display devices, each decoding device is connected to the display device through the display port. When the decoding device fails, the display device cannot display normally, resulting in interruption of the display service, which can only be achieved through human intervention. Back to normal. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide a display system and a method for hot backup of a decoding device and a backup decoding device, which are used to solve the problem of display service interruption caused by a failure of a decoding device in an existing display system. [0004] The purpose of the embodiments of the present invention is ac...
