Huawei's 'Gold Medal Customer Service” Bruce Lee Reveals Beidou Satellite Image Message: Compressed to 400 Chinese Characters and Sent

According to news on August 1, Huawei Terminal BG CTO Bruce Lee published an article today revealing the principle of the Beidou satellite image message function: the image is compressed through a compression algorithm, the received photo is saved in JPEG format, and the file size becomes 62.88KB.

According to reports, the current Beidou satellite short messages do not support data transmission. Huawei uses a compression algorithm to compress the image to 800 Byte (equivalent to the space of 400 Chinese characters), and then sends it. Received photos are saved in JPEG format, with file sizes approximately 80 times larger than before compression.

A user asked about the compression of photos of outdoor scenes in the Weibo comment area, and Bruce Lee replied with pictures of landscape photos. Fenye inquires and learned that the Beidou satellite picture messaging function is currently only supported by Huawei Pura 70 series mobile phones (excluding the standard version). In principle, this function is the same as the free editing and sending of Beidou messages. It needs to be used in a non-network environment, but it can be used by turning off the SIM card and WIFI.
