System and method for preconditioning analog video signals |
摘要 |
A composite analog video signal can be preconditioned by a preconditioning device that removes noise from the composite analog video signal. The preconditioning device can comprise a low-pass filter that removes noise from the composite analog video signal by passing frequencies of the composite analog video signal below about 6 MHz. A decoder can amplify the preconditioned composite analog video signal and can decode the amplified signal into digital component signals. A compression module can encode the digital component signals for transmission over a communication network. The compression module can encode to the digital component signals using an MPEG-1 or other compression standard.
