Abstract
An apparatus and method of fine adjustment of tuning data for a TV receiver which can achieve fine adjustment of tuning data quickly and accurately. The apparatus includes a AFT information memory for storing AFT information on the detuned frequency of a selected channel, and a microcomputer for reading the corresponding AFT information of the selected channel from the AFT information memory and providing tuning data by calculating the read AFT information and a center frequency of the selected channel. The microcomputer also performs search operation if the broadcasting signal of the selected channel is inaccurately tuned in order to detect the detuned frequency thereof. The apparatus is also provided with a fine adjustment key for increasing/decreasing the tuning data so as to perform accurate tuning. The tuning data increased/decreased by the fine adjustment key is then stored in the AFT information memory for use in the next tuning.
