Abstract
A method and device for adapting an existing analog television receiver to receive and decode both analog and digital television signals. A digital module is provided within the analog television receiver and its output is provided to the picture-in-picture (PIP) interface of an analog module within the receiver. The digital signal then has the benefit of using the picture improvement circuitry located within the analog module and there is no need to modify the analog module which has been in the cost optimization process for years.
