Abstract
A receiving apparatus and a receiving method arranged to reduce the delay time of tuning to and reception of a digital TV broadcast actually and apparently. A coefficient memory for storing coefficient data to be supplied to a channel equalizer of a front end section is provided. A control section generates equalizer coefficients supplied to the channel equalizer by using the equalizer coefficients in the coefficient memory, and updates the equalizer coefficients stored in the coefficient memory by substituting the generated equalizer coefficients for them. The control section supplies a predetermined video signal to a display section instead of a video output from a decoding section before the video output from the decoding section is obtained.
