Video decoder block

摘要

A video decoder block provides a common pathway for processing video signals encoded using different video formats. The video decoder block passes the video signals through the same processing components in order convert the signals to a common format for display or storage. Each processing component cat be disabled or by-passed to enable or disable the function performed by the component. This reduces the number of components and signal processors required in devices that need to accommodate signals of different formats.

1. A method for converting analog video signals to digital video signals, the method comprising:
receiving an analog video signal; determining a characteristic of the analog video signal; converting, with an analog to digital converter and based on the characteristic of the analog video signal, the analog video signal to a digital video signal having a video resolution; selectively disabling at least one of a low pass filter or a decimator of a video converter as a function of the video resolution of the digital video signal, the video converter comprising the analog to digital converter, at least one automatic gain control component, the low pass filter, and the decimator; and processing the digital video signal using the video converter to produce a digital video output signal.
