However, the technical scheme of the patent has the following problems:

1. The internal board card adopted by the scheme mainly comprises an input card, an output card and a control card, and the mode of the board card is that the number of discrete board cards used is large, so that the failure rate is high and the maintenance cost is high; and because the integration level of the combination mode of the internal board card is not high, the whole audio and video splicing processing device is large in size, complex in internal structure and low in internal space utilization efficiency.

2. The number of the input interfaces and the output interfaces of the scheme is directly limited to the number of the slots, the signal sources can be collected and output only by means of the input cards and the output cards in a hardware mode, the signal sources can not be collected in a network transmission mode, the limitation of the hardware of the case shell can not be broken through, and the electromagnetic compatibility of the internal space can be reduced.

3. When the number of input interfaces and output interfaces preset by the audio and video splicing processing equipment is relatively large, and when the number of the input interfaces and the number of the output interfaces required by an actual scene are relatively small, the audio and video splicing processing equipment can reduce the number of the input cards and the output cards, so that empty slots can appear in the audio and video splicing processing equipment, and external dust can be very attached to the empty slots at the time, so that the stability of the multi-screen image splicing processor in long-time operation is affected.
