Control signal embedding method, the video signal frame identification system and control signals embedded system

摘要

The command embedding systems and methods enable embedding control signals into standard video signals during recording. Specifically, a user selects a mode of operation of the command signal embedding system. Based on the selected mode, control signals are either manually or automatically embedded in a video signal as the video signal is recorded. The control signals may include, but are not limited to, commands that identify the state of the video camera or the environmental conditions surrounding the video camera or commands that tag key frames in the video signal. Once the control signal is received and embedded, the embedded control signal may be recorded, for example, to facilitate further editing, or may be directly televised or broadcast with further manipulation in mind.
