Technical Advances in Type-C Picture Processing
The time-base corrector (TBC) plays an important role in the operation of the Type-C VTR, for most of the features and adjustments are delegated to this unit. Residual uncorrected time-base errors contribute to the VTR's multiple-generation performance limitations. This article describes a high-performance TBC with a 4-f sc sampling clock frequency and 9-bit linear quantization. Digital signal processing is use a throughout the TBC for picture manipulation and digital control of ah operational and preset video adjustments. The stability attained by this form of processing enhances the operational flexibility of these recorders.
