Abstract
In a system for transmitting and receiving a television signal via a transmission channel having at least a transmitting section and a receiving section, the transmitting section including a sampling circuit for sampling each field of the television signal in accordance with a sampling pattern which is shifted field-sequentially at least in the horizontal direction, the transmitting section further includes a field interleaving circuit for generating a field to be transmitted by interleaving between sampling values of a sampled field of the television signal sampling values of at least one further sampled field of the television signal having mutually different shifted sampling patterns, so that a higher temporal resolution is possible on display of the television signal.
