Data is sent in the form of analog signals from an analog video resource. For example, TV broadcasting stations and satellite broadcasting TV channels are analog resources that send video and audio signals as electromagnetic waves. A VHS cassette player is another example of an analog resource that outputs analog video and audio signals.
We can categorize analog video resources into equipment that receives analog signals as waves (like a TV antenna or satellite receiver) and equipment that uses analog media(like 8mm, VHS, and Hi8 tapes). Various devices like VCRs (Video Cassette Recorders), Camcorders, and 8mm Projectors are needed to play these media.
We can get output signals from analog video resources using three output cables. (In fact we can find three input ports in every capture card used for receiving analog signals.)
The first port is the antenna jack, used for receiving analog signals from TV channels and satellite receivers. This port is used to capture...
