Patent ID: 7528888

Claim:
A television broadcast receiver comprising: a tuner that receives a television signal; signal strength detecting means for detecting a strength of the television signal received by the tuner; desired to undesired (D/U) ratio determining means for determining a D/U ratio of the television signal received by the tuner to detect multipath effects; carrier to noise (C/N) ratio determining means for determining a C/N ratio of the television signal received by the tuner to detect interference impairment; received signal quality informing means for presenting information on a quality of the television signal received by the tuner to a user; receiving condition evaluation table storage means for storing a receiving condition evaluation table used for overall evaluation of a condition of the reception of the television signal received by the tuner, the receiving condition evaluation table containing an overall evaluation value, indicating a condition of reception of a television signal, for each combination of a signal strength, a D/U ratio, and a C/N ratio; and overall evaluation value determining means for reading the receiving condition evaluation table to determine an overall evaluation value for the television signal received by the tuner based on the signal strength detected by the signal strength detecting means, the D/U ratio determined by the D/U ratio determining means, and the C/N ratio determined by the C/N ratio determining means, wherein the received signal quality informing means presents the overall evaluation value determined by the overall evaluation value determining means to the user.
