Abstract
Display interface embodiments are provided to capture various types of analog video signals and digitize them for presentation on advanced digital displays (e.g., computer displays and television displays). The embodiments include at least an error converter channel and a reference converter channel that can each amplify an analog input signal S with a fixed gain G and a programmed gain g and convert the amplified signal to a corresponding digital code. The embodiments also include a channel controller that is configured to conduct process steps that adjust the transfer function of the error converter channel to conform to (e.g., matches) the transfer function of the reference converter channel.
