This invention relates to the field of
computer technology and discloses a distributed display control method and
system supporting
multimedia file display. The method includes, in response to a display command, acquiring a
multimedia file and loading it to a playback control terminal, generating an overall display screen, and splitting it into multiple sub-screens using a
graphics card internal splicing method to form multiple display signals. These signals are then sent to multiple correspondingly connected encoding transmission nodes, encoded as network signals, and combined at the display control terminal into a virtual extended
signal source. In response to a
display arrangement command for the extended
signal source, the display control terminal associates the extended
signal source with a decoding display node and sends control commands to the decoding display node to decode the network signals received from the encoding transmission node into display signals and drive the corresponding display terminal to display the image. This invention supports the splicing and output of ultra-
high resolution multimedia content, enabling direct display without the need for additional playback equipment or manual switching.
