Abstract: The invention relates to a method for optimizing signal reception for a broadcast data receiver. Broadcast Data Receivers are used to receive digital data transmitted from a remote location, process the same and then generate video, audio and auxiliary services. However the Broadcast data receiver is typically located in a household and can be susceptible to general and/or local conditions which affect the reception of the data signals at different frequencies. The present invention provides a method for optimizing the signal reception at the broadcast data receiver location by allowing the analysis of amplitude gain control levels of the broadcast data receiver and then selecting the amplitude gain control levels and/or other levels which optimize the quality of the received signal at each frequency.

Abstract: A method and system is provided for controlling the storage of data. The data is broadcast to and received by a broadcast data receiver and the receiver is provided with or connected to memory in which the data, including video data is to be stored. At an instant decided by any or any combination of control parameters, a portion of the data held in the memory is selected, compressed/recompressed and stored in the memory in the compressed condition.

Abstract: The invention relates to the provision of a broadcast data receiver with at least one tuner and a control system therefore. The tuner is tuned to specific frequencies to obtain transmitted data from which a television channel can be generated. The frequency tuned to is dependent on the channel selected and the invention allows the output signal quality for the channel at each frequency to be optimised by allocating a take over point value at which the transition between radio frequency amplitude gain control and Intermediate frequency amplitude gain control occurs on a channel frequency by channel frequency basis rather than the conventional general take over point value.
