Encoders

Head End Encoders are used to scramble premium channels by introducing a jamming signal in the middle of the premium channel's video and audio carriers. A positive filter, installed in the subscriber's drop path, decodes, or unscrambles the jammed signals and restores the picture and sound.

Model EE-2002 and EE-EOSC

Eagle's Model EE-2002 dual discrete jamming carrier offers improved scrambling by using dual IF carriers. Model EE-2002 introduces Eagle's patented "Dual Stage Pre-emphasis" at the headend which compensates the video near the jamming carrier and sharpens or enhances the decoded picture.

Eagle's Model EE-EOSC uses a single RF jamming carrier. There is no pre-emphasis. The EOSC is also used to simulate a lower jamming audio subcarrier when a lower adjacent television channel is not present.

Model EE-3002

The EE-3002 uses Eagle's patented Sideband Interdiction System to utilize the channel's own sideband information as interdiction energy. A Sideband Interdiction Decoding filter is used at the subscriber drop to decode the signal for the paying subscriber to near perfect condition with full frequency response, sharpness and definition. The Model EE-3002 features AGC Gain Control, Interdiction Level Control, Remote Activation, and a Front Panel On/Off switch.
