Abstract
According to the main application P 38 31 103, the HDTV signal is divided into two signal components, whereby the first is a standard TV signal and the second is a spatial high-resolution and temporal low-resolution HDTV signal. An improved receiver can now (a) still correct movement vectors transmitted as well; (b) transmit in the second channel by digital signals a reference for the level and phase of the signal in the first analog channel; (c) evaluate information transmitted as well which indicates where the second channel may be found in the frequency band; (d) contribute towards the reduction of the necessary store size in a future television system with two digital channels by switching over per image and through the omission of an image regeneration circuit with two image stores. Compatible television transmission system for an HDTV signal.
