Embodiment 1
[0023] like figure 1 As shown, the first embodiment of the present invention provides a display system 100, the display system 100 includes N display units 110 and N video distributors 120, the main data stream flows through each video distributor 120; each video distributor 120 120 is respectively connected to a display unit 110 through a sub-data stream channel 12 to send the corresponding sub-data stream to the corresponding display unit 110 respectively, and N is a positive integer greater than 1.
[0024] In this embodiment, as figure 1As shown, the N video distributors 120 are connected in cascade through the main data stream channel 11 in sequence, and the N video distributors 120 are sequenced according to the cascading sequence, and the first video distributor 120 is connected to the signal source in a preset manner, to access the main data stream. The main data stream input by the signal source refers to the signals required by the display system, including video s...
Embodiment 2
[0035] like Figure 4As shown, Embodiment 2 of the present invention provides a data transmission method for a display system. Based on the display system 100 in Embodiment 1 above, the data transmission method includes the following steps:
[0036] Step S110: Receive a sub-data stream request sent by the corresponding display unit according to its own parameters.
[0037] Specifically, as figure 1 As shown, the first video distributor 120 is connected to the signal source in a preset manner to access the main data stream. When the display system in the first embodiment performs video display, the main data stream formed by the current display image flows through each video distributor 120 in sequence, that is, each video distributor 120 receives the signal source or sends it from the previous video distributor 120 and send all the main data streams to the next video distributor 120. During this process, the main data streams transmitted by each video distributor 120 to the ...
Embodiment 3
[0042] like Figure 5 As shown, the third embodiment of the present invention provides a data transmission method for a display unit. Based on the display unit 110 of the display system 100 in the first embodiment, the data transmission method includes the following steps:
[0043] Step S210: Read the sub-data stream and the excitation signal synchronously sent from the corresponding video distributor, respectively.
[0044] Specifically, as figure 1 As shown, the first video distributor 120 is connected to the signal source in a preset manner to access the main data stream. When the display system in the first embodiment performs video display, the main data stream formed by the current display image flows through each video distributor 120 in sequence, that is, each video distributor 120 receives the signal source or sends it from the previous video distributor 120 and send the main data stream to the next video distributor 120 synchronously. During this process, the main ...
