Abstract :
A method of subsampling suitable for FM transmission of multiplexed analogue component (MAC) video signals is described. A modified quincunx subsampling lattice is used with a zigzag scanning pattern over two TV lines. Simulation results for interpolation using samples in the current field only, are presented to compare this method with an alternative method in which alternate lines of video are deleted.
