DEVICE FOR INDICATING THE RECEIVED SIGNAL QUALITY IN A DIGITAL RECEIVER

摘要

A device for indicating the quality of a received digital broadcast video signal in a digital television receiver includes circuitry for determining the amount of multipath interference. Preferably, the device generates a display graph indicative of the signal quality. Optionally, the device may also consider, in determining the signal quality, whether a demodulator in the television receiver is able to lock onto a sync sequence in the video signal, whether an adaptive equalizer also in the television receiver is able to lock onto the sync sequence, and the amount of errors being corrected in an error correction circuit in the television receiver.
