The invention discloses a multi-channel video display method of a broadcast instructing platform and a multi-channel video display device thereof. The multi-channel video display method comprises the steps that multi-channel first video signals are acquired; the size and the display position of each channel of first video signal are determined according to the number of channels of the multi-channel first video signals and the preset resolution of a second video signal; each channel of first video signal is transformed into the corresponding size and the first video signals are merged into one channel of the second video signal according to the display position; and the second video signal is outputted to display equipment of the broadcast instructing platform to be displayed. The load of the display equipment of the broadcast instructing platform can be effectively reduced, and the situation that the broadcast instructing platform cannot normally work due to overload of the display equipment can be prevented.
Description
technical field [0001] The invention belongs to the field of network video, and in particular relates to a multi-channel video display method and device for a broadcasting station. Background technique [0002] At present, the director station in the video industry mostly refers to the director station technology in the field of TV program production, which is mainly used to switch between different video sources to achieve the perfect effect of TV programs. For example, in a live broadcast, there will be cameras in different directions to transmit image signals in different directions to the director switcher at the same time, and the director will choose one signal as the output according to the effect required by the program. [0003] For the display of multi-channel signals, multiple display devices are often required, and if multiple signals are played on one display device at the same time, it is equivalent to the preview method of opening multiple players on one displ...
