1. A method for transmitting reduced depth information, comprising:
obtaining, by a remote server, a first depth map of an image frame, wherein the first depth map comprises a plurality of first depth pixels corresponding to a plurality of image pixels in the image frame;
downscaling, by the remote server, the first depth map as a second depth map, wherein the second depth map comprises a plurality of second depth pixels, and each second depth pixel has a depth value;
adjusting, by the remote server, the second depth map as a third depth map by scaling up the depth value of each second depth pixel based on a specific ratio;
dividing, by the remote server, the third depth map into a plurality of fourth depth maps;
appending, by the remote server, the fourth depth maps to the image frame;
encoding, by the remote server, the image frame appended with the fourth depth maps; and
transmitting, by the remote server, the encoded image frame to a client device.
