Method and system for video encoding using noise level estimates from vertical blanking interval TV lines

摘要

A system and method for video encoding using noise level estimates from vertical blanking interval lines. A video signal may be received by an encoding system. Information may be extracted from the video signal and may be analyzed. The extracted information may be vertical blanking intervals. The extracted and analyzed information may be utilized to estimate a noise level of the video signal. The estimated noise level may then be utilized in encoding the video signal by being inserted into the video signal or used to change parameters used in video encoding.
