Claims
- 1. A system for analyzing a plurality of video parameters of an analog signal received from an analog source, including horizontal and vertical sync times and active video time, said analog signal including horizontal and vertical sync pulses and an active video image portion, said system comprising:pixel generating means for generating a first plurality of pixels at the beginning of said active video portion of said analog signal and a second plurality of pixels at the end of said active video portion of said analog signal; and a video format analyzer communicatively coupled to said pixel generating means, wherein said video format analyzer commences measurement of said active video image portion of said analog signal upon detection of said first plurality of pixels.
- 2. The system of claim 1, wherein said video format analyzer stops measurement of said active video image portion of said analog signal upon detection of said second plurality of pixels, the video format analyzer thereby determining the position and duration of said active video image portion within said analog signal.
- 3. The system of claim 2, where said pixels are blue.
- 4. A method for analyzing a plurality of video parameters of an analog signal received from an analog source, including horizontal and vertical sync times and active video time, said analog signal including horizontal and vertical sync pulses and an active video image portion, comprising:generating a first plurality of pixels at a beginning of said active video portion of said analog signal and a second plurality of pixels at an end of said active video portion of said analog signal; and measuring said active video image portion of said analog signal upon detection of said first plurality of pixels.
- 5. The method of claim 4, further comprising stopping measurement of said active video image portion of said analog signal upon detection of said second plurality of pixels, thereby determining the position and duration of said active video image portion within said analog signal.
- 6. The method of claim 5, wherein at least one of said first plurality of pixels and said second plurality of pixels is blue.
