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.
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.
Abstract:
A data reader for reading data provided as part of a barcode (2). The barcode (2) includes a plurality of black bars (6) and white spaces (8) in a pre-determined arrangement (4), with characters in the form of numbers (10) represented by the pre-determined arrangement (4) provided adjacent the arrangement. The data reader is provided with image capture and processing means to identify the barcode (2) and/or the numbers (10), capture at least one image of the numbers (10) and process the at least one image to identify the numbers (10) and read data represented by the numbers. The data is then used by the data reader to identify an item or items to which the barcode (2) corresponds or one or more attributes of the item.
Abstract:
The present invention relates to a method and system for selecting the particular location for the storage of e-mails or other electronic documents in a storage means. Conventionally electronic documents are stored in a manner which allows the same to be identified and retrieved from a multilayered, or hierarchical storage structure. The present invention allows the electronic documents to be stored in a selected location with the selection being made by comparison of predefined attributes of the storage location with attributes of the document. Weighting values can also be allocated to the locations and the attributes and weighting values can be revised following the receipt and storage of a document.
Abstract:
The invention relates to the generation of an on-screen display and a control system for the same which allows the known problems in display which can occur to be avoided. Upon change of at least part of an OSD, the system continues until a request to redraw the display is received. At this stage, if the Vsync signal of the display screen has occurred since the change the redraw occurs immediately, thereby avoiding unnecessary delay.
Abstract:
The invention relates to a television system incorporating a display screen (2), broadcast data receiver (3), remote control device (6) and the generation of an EPG on screen which provides information relating to programs and channels which can be viewed. In accordance with the invention the user can select one or a number of said channels and/or programs from said EPG and designate a button or button configuration on the remote control (6) for each selected channel/program or a number of selected channels/programs. The selected channel(s)/program(s) typically relate to pre-defined criteria, such as subject matter categories, user-favorite channels or similar. Once designated the user can then subsequently select a channel/program for display by depression of the appropriate button or button configuration.
Abstract:
The invention relates to a television system of the type which includes a display screen, a broadcast data receiver for the reception of video, audio and auxiliary data from a broadcast service provider and the generation of television programmes therefrom for display on the display screen and via speakers. The system allows a user to select a viewing time period in which they wish to watch a programme, typically in its entirety. The system identifies those of the available programmes at the start of the viewing time period which can be watched in their entirety in said period and indicates the same to the user who can then select to watch the same or one of the same. The user can therefore quickly select a television programme for a given period of time thereby greatly reducing the time which may be spent flicking through channels to find a suitable programme.
Abstract:
The invention relates to the provision of electrical apparatus which has at least one printed circuit board on which electrical components are set out and a first format of connection type exposed to allow connection of further apparatus. The connections can be attached directly to further apparatus with the same connector format and allow transfer of data between further electrical apparatus or alternatively, at the time of manufacturing an adaptor can be provided which has connectors of the same format as those on the printed circuit board for connection with the said printed circuit board and a series of output connectors of a different format which can be exposed for the selective connection thereto of phono or other format connectors. This therefore allows a common printed circuit board design to be used for electrical apparatus for sale in any market, regardless of the particular type of connectors which are used to connect the printed circuit board to other pieces of apparatus in that market and a decision to be made by the manufacturer at the time of manufacture as to whether or not to connect the adaptor dependent on the ultimate destination of the apparatus.
Abstract:
The invention relates to a system and method for the generation of television channels and which allows the generation of the same by the processing and selection of designated packets of data from multiple data transport streams, with each transport stream including numerous packets of data. In each transport stream the packet of data is identified by the allocation of a packet identification Code (PID) and each is held in the transport packet which is transmitted as part of each transport stream. In accordance with the invention, and in order to prevent errors and inaccurate packet selection, a Transport Stream Identification Code (TSID) is allocated to each of the transport streams of data received. Typically the TSID is located in the transport packet for each transport stream of data. In the selection of a packet of data, the appropriate TSID is referred to identify the appropriate transport stream and the PID then referred to identify the packet of data from that transport stream.
Abstract:
A method is provided for delivery of ordered goods to a secure location. The secure location at a premises (3) is accessed by securing means (10) which can be opened by the input of a security code. The method includes the generation of a security code at the time of ordering the goods from a retailer (5). The generated security code is communicated to the deliverer of the goods and to the securing means (10) at the secure location and input of the security code by the deliverer into the security means causes the security means to be opened and the ordered goods to be located in the secure location. The order can be placed using a broadcast data receiver (2).
