Abstract
An asymmetric image transmission method and an electronic device thereof are provided. The asymmetric image transmission method is applicable to transmission of an image signal from a transmitter to a receiver and includes: modifying, by the transmitter, a first image pixel length in the image signal that conforms to a four-byte mode to a second image pixel length of a three-byte mode; transmitting a plurality of image pixels of the second image pixel length in the three-byte mode respectively through three transmission lanes of a transmission interface; and modifying, by the receiver, the second image pixel length of the image pixels to the first image pixel length of the four-byte mode to obtain the image signal.

An asymmetric image transmission method, applicable to transmission of an image signal from a transmitter to a receiver, comprising:
- modifying, by the transmitter, a first image pixel length in the image signal that conforms to a four-byte mode to a second image pixel length of a three-byte mode;
- transmitting a plurality of image pixels of the second image pixel length in the three-byte mode respectively through three transmission lanes of a V-by-One transmission interface;
- and
- modifying, by the receiver, the second image pixel length of the image pixels to the first image pixel length of the four-byte mode to obtain the image signal;
- wherein the transmitter is a graphic direct memory access (GDMA) chip, and the receiver is a write direct memory access (WDMA) chip.
An electronic device for asymmetric image transmission, comprising:
- a transmitter, configured to modify a first image pixel length in an image signal that conforms to a four-byte mode to a second image pixel length of a three-byte mode;
- a V-by-One transmission interface, electrically connected to the transmitter, and configured to transmit a plurality of image pixels of the second image pixel length in the three-byte mode respectively through three transmission lanes;
- and
- a receiver, electrically connected to the V-by-One transmission interface, and configured to modify the second image pixel length of the image pixels to the first image pixel length of the four-byte mode to obtain the image signal;
- wherein the transmitter is a graphic direct memory access (GDMA) chip, and the receiver is a write direct memory access (WDMA) chip.
