Abstract: The invention provides a method for searching the frequency range of a digital data receiving device, said method including the steps in one embodiment of firstly identifying and disregarding analogue carrier frequencies in the range, then proceeding to estimate the initial starting frequency for a digital carrier by dynamic real-time pre-processing of the spectrum profile and then obtaining successive samples of the frequency range from the start position for the carrier until the centre frequency for the carrier is located. In one embodiment the method includes the prediction of the centre frequency estimations of all digital carriers for respective channels in the range prior to the search commencing. The method reduces the possibility of locking to analogue carriers, and can reduce the time required to perform a search in comparison to the current digital carrier frequency "search & lock" procedure

Abstract: The invention relates to improvements to the operation of a broadcast data receiver (BDR) and, in particular, to the provision of a video data amplifier and driver circuit for the processing of a received video data signal. The circuit includes a means for generating at least one compensatory value and preferably a multiplication factor. The compensatory value is added to the received video data signal as it passes through the circuit to form a combined signal. The combined signal can also be multiplied. The level of the compensatory value can alter with reference to changes in the environment of the operation of the circuit so as to take into account and minimise changes affecting the operation of the circuit and on the video signal.
