Description
Technical Field
The invention relates to the technical field of display, in particular to a signal seeking wall-mounting method and a signal seeking wall-mounting device.
Background
With the continuous expansion of various information types and the continuous increase of system operation complexity, industry users need to establish a large-screen display system capable of integrating multiple signals.
A tiled wall, also called a tiled wall, is a large-screen display system composed of multiple display units and an image controller, and is generally used for ultra-large screen display of one picture and multi-window display of multiple pictures. The spliced wall has a large combined space: the small screen splicing and the large screen splicing can be adopted; the single-screen splicing can be carried out one-to-one, and the whole screen splicing can be carried out one-to-one; and the large screen and the small screen can be spliced in a mixed mode.
Currently, the display processing procedure of the split wall control software for scheduling IP display to be on the wall is as follows:
1. the wall splicing control software sends a control instruction to the processor control board card through the switch, wherein the control instruction comprises a signal source IP to be connected, a signal type and a channel of which IP service board card of the processor is used;
2. the processor control board informs the IP service board card and the channel selected by the wall splicing control software to be connected with the signal source IP through the backboard;
3. if the signal source is successfully connected, the IP service board card acquires signal source data and sends the signal source data to the output board card through the backboard for display;
4. if the signal source fails to be connected, the IP service board feeds back a control board failure message through the backboard, and the control board informs the output board of displaying no video signal through the backboard.
In the step 1, when the processor has a plurality of IP service boards or one IP service board capable of decoding multiple IP signals, the wall-splicing control software needs to seek the IP service boards (i.e., which channel of which IP service board is selected to connect to the actual signal source IP). Although the above-mentioned method for displaying on the wall by scheduling the IP signal by the wall-splicing control software can realize simple display on the wall, the method has the following disadvantages: the wall-splicing control software only adopts sequential seeking, the seeking rule is not flexible enough, and the directional seeking can not be realized.

the configuration unit is used for configuring the IP signal source and additionally arranging the directional seek identifier on the IP signal source to be directionally sought;
the wall-mounting unit is used for sending the slot position number corresponding to the target IP service board card and the channel number corresponding to the target connecting channel to a control board card, and the control board card sends the signal data of the IP signal source to an output board card through a backboard for wall-mounting display; the target connection channel is a connection channel selected from the target IP service board card according to a preset selection channel rule;
the transmission subunit is used for sending the slot position number corresponding to the target IP service board card and the channel number corresponding to the target connection channel to the control board card;
the display subunit is used for the control board card to send a connection instruction to the target IP service board card and the target connection channel, so that the IP signal source is communicated with the target IP service board card through the target connection channel, and the control board card sends the signal data of the IP signal source to the output board card through the backboard for spliced wall display;
the first display subunit is used for the control board card to send a connection instruction to the target IP service board card and the target connection channel, so that the IP signal source is communicated with the target IP service board card through the target connection channel;
and the second display subunit is used for sending the signal data of the IP signal source to the back plate by the IP service board card, sending the signal data to the output board card by the back plate, and splicing and displaying the signal data by the output board card.
8. The signal-seeking wall-mount apparatus according to claim 7, wherein the directional-seeking rule specifically comprises:
acquiring a directional seek identifier, and determining a target IP service board card according to the directional seek identifier;
selecting a target connection channel in the target IP service board card according to a preset selection channel rule;
the sequential seek rule specifically includes:
for two or more IP service board cards, preferentially selecting the IP service board card with the first cis-position slot position number as a target IP service board card;
selecting a target connecting channel for the same IP service board card according to a preset channel selection rule;
the preset selection channel rule is specifically as follows: the first cis numbered channel that is not used is preferentially selected.
