A television broadcast receiver determines the signal strength, the desired to undesired (D/U) ratio, the carrier to noise (C/N) ratio of a received television signal. Based on these values, the television broadcast receiver determines an overall evaluation value indicating the condition of reception of the television signal by reading a receiving condition evaluation table and determines a message explaining the condition of reception of the television signal by reading a message table. Then, the television broadcast receiver presents to a user the determined overall evaluation value and message along with the signal strength, the D/U ratio, and the C/N ratio. Accordingly, the user can easily make a judgment on whether the receiving condition is good or not based on the overall evaluation value.
