Abstract: An association engine for organizing content items in a logical database is provided. First description data including dimension data for a first identified content item in the database is extracted (S1). This process may be repeated for additional available identified content items (S3). Candidate description data is extracted (S5). Then, a set of vector values for each candidate content item may be generated (S11), each vector value representing a degree of similarity between the dimension data for a dimension, for example, metadata, usage history, genre, content type, of the first description data and the corresponding dimension data of the candidate description data. A similar candidate content item from the candidate content items may be selected (S15) based on the degrees of similarity represented by the generated set of vector values, and grouped (S16) with the first content item in the organization of the logical database.

The invention avoids the conventional need to remove the items of apparatus at the storage location for the performance of the checks and procedures by providing a package with selectively removable portions which, when removed, allow the required access to the components of the apparatus without needing to remove same from the package.

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 center frequency for the carrier is located. In one embodiment the method includes the prediction of the center 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 a method of controlling the operation of a voltage controlled oscillator (VCO) with respect to a SAW filter (6) within a broadcast data receiver (BDR) (104). Over time, it is found that during normal operation of the BDR (104), the SAW filter (6) is susceptible to frequency drift which can affect the operation of the BDR. In accordance with the invention, temperature readings are taken at various time intervals from within the BDR (104) to provide an indication of changes in temperature over time and, if the temperature does change in the BDR with time then the operating frequency of the VCO can be adjusted to a predefined frequency value which is appropriate for the temperature values measured. By adjusting the operating frequency of the VCO with changes in temperature, the drift of the SAW filter (6) can be compensated for, thereby ensuring the continued operation of the BDR (104) in the required manner.
