Abstract: The present invention discloses an apparatus for receiving an ordered sequence of input data and for delaying the output of a delay output item by a variable-length delay-time. The apparatus includes an input port for receiving the ordered sequence of input data and the variable-length delay-time. The apparatus further includes an integrated data storage, a random access memory (RAM) for storing the ordered sequence of input data according to a storage-order corresponding to the ordered sequence of the input data. The apparatus further includes a delay output port for accessing and outputting the delay output item in the storage means according to the variable-length delay-time and the storage-order such that the delay output item is delayed by the variable-length delay-time.

Abstract: A system is disclosed for cancelling ghosts including I daisy chained variable delay elements, the first of which receives a video signal. J multiplexers are also provided, each of which has at least one input connected to the output of each of the I variable delay elements. A transversal filter element is connected to the output of each multiplexer for filtering the delayed video signals selected by the corresponding multiplexer connected thereto. Finally, an adder is provided for adding together the filtered video signals outputted by the transversal filter elements.

Abstract: The present invention comprises a method for characterizing a multi-path signal transmission in transmitting a plurality of signals with a plurality of cyclic fields each including a plurality of horizontal scanning periods wherein some of the scanning periods are vertical blanking periods. The method comprising the steps of: (a). transmitting periodically in a plurality of the scanning periods in one of the fields at least two reference signals each with a different predefined signal characteristics; (b). receiving the plurality of signals including the reference signals; and (c). processing the received signals including the received signals of reference signals for detecting a multi-path channel delay of the signal transmission.
