Abstract
A hybrid analog/digital STB includes a tuner supplying respective analog and digital television signal processing paths. The analog processing path provides demodulated composite analog video and audio signals and the digital processing path provides demodulated component digital video and audio signals. The demodulated analog and video signals are combined in composite or component form to achieve various desirable effects in a highly flexible system architecture. OSD and display map normalization functions are also integrated within the system architecture.
