Television signal processor for processing any of a plurality of different types of television signals

A television signal processor comprising:

• a signal processing section having means for determining a system from which the television signal processor receives a television signal, the signal processing section decoding the received television signal in accordance with the determined system;
• a display for displaying an image corresponding to the decoded television signal;
• and
• controlling means for processing the decoded television signal for the display based on specification data of the display, the controlling means including:
• means for inputting the specification data for the display,
• means for calculating one of a culling rate and an interpolating rate based on the decoded television signal, the culling rate being one of a horizontal culling rate and a vertical culling rate, and the interpolating rate being one of a horizontal interpolating rate and a vertical interpolating rate, based on the input specification data and the result of determination performed by the system determining means,
• culling means for determining a first coefficient based on the culling rate calculated by the calculating means, and for executing one of a horizontal and vertical culling process with respect to the decoded television signal by multiplying the decoded television signal by coefficients corresponding to the first coefficient,
• interpolating means for determining a second coefficient based on the interpolating rate calculated by the calculating means, and for executing one of a horizontal and vertical interpolating process with respect to the decoded television signal by multiplying the decoded television signal by coefficients corresponding to the second coefficient,
• time conversion means for performing a time-axis conversion process with respect to the decoded television signal based on the specification data input for the display, the time-axis conversion process making the decoded television signal correspond to a synchronizing frequency of the display, and
• synchronizing processing means for generating a synchronizing signal for driving the display based on the specification data for the display, and for outputting the synchronizing signal to the display,
• so that the image corresponding to the decoded television signal can be displayed on the display.
