A Simple Family of Digital Filters for a Binary Hierarchy

The concept of a binary hierarchy or family of TV picture quality levels is described. A family of digital filters designed for such a binary hierarchy is introduced. The main advantage provided by these filters is that they can be used to perform most up-conversion and down-conversion processes while utilizing essentially the same hardware components, the same boards, and the same layout. The filter's function is changed by means of wire jumpers and external control signals. The family concept can be extended to more complex filters. The use of these filters in the Digital Hierarchy Demonstrations is described.
