Data transmission method, apparatus and system, device and storage medium

A data transmission apparatus, comprising:

• a processor;
• a communication interface connected with the processor;
• a memory storing a computer program and connected with the processor;
• wherein the computer program, when executed by the processor, cause the processor to:
• acquire data of a display image layer and data of a transparency layer, and determine, based on the data of the display image layer and the data of the transparency layer, multiple sets of data to be superimposed;
• construct a target layer based on the display image layer and the transparency layer for each set of data to be superimposed;
• determine first placement data and second placement data of the target layer based on the data of the display image layer and the data of the transparency layer for each set of data to be superimposed;
• place the first placement data to a first position of the target layer and place the second placement data to a second position of the target layer, to obtain data of the target layer;
• transmit, through the communication interface, data of multiple target layers.

A data transmission system, comprising:

• a first chip, comprising a graphics processing unit (GPU), a display processing unit (DPU) and a first interface that are connected communicatively;
• wherein the GPU is configured to acquire data of a display image layer and data of a transparency layer, and determine, based on the data of the display image layer and the data of the transparency layer, multiple sets of data to be superimposed;
• construct a target layer based on the display image layer and the transparency layer for each set of data to be superimposed;
• determine first placement data and second placement data of each target layer based on the data of the display image layer and the data of the transparency layer for each set of data to be superimposed;
• place the first placement data to a first position of the target layer and place the second placement data to a second position of the target layer, to obtain data of each target layer;
• and send data of multiple target layers to the first interface based on the DPU;
• a second chip, configured to receive the data of the multiple target layers sent by the first chip through the first interface.
