MUMBAI, India, June 6 -- Intellectual Property India has published a patent application (202414077434 A) filed by Shanghai Tosun Technology Ltd., Shanghai, on Oct. 11, 2024, for 'time synchronization method of video information and bus message information and electronic device.'
Inventor(s) include Liu, Chu; Xie, Yueyin; and Mo, Mang.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "A time synchronization method of video information and bus message information includes: defining a timestamp of the video information as a basic timestamp; upon starting recording, obtaining a first-frame timestamp T0 of the video information, and aligning a first-frame timestamp of the bus messages with the first-frame timestamp T0 of the video information and recording each frame timestamp Ty of the aligned bus messages; upon stopping recording, obtaining a tail-frame timestamp T1 of the video information and a tail-frame timestamp T2 of the bus messages; setting a ratio coefficient k=(T1-T0)/(T2-T0); traversing all recorded bus messages and modifying and storing each frame timestamp Ty of these bus messages as Tx, wherein Tx = T0+(Ty- T0)* k; and each frame timestamp Tx of the bus messages is recorded based on a clock of the video information."
