In overview, a system and method for determining the location of a device are disclosed. Typically, the device is generally static such that its location does not vary significantly over time, for example, a television appliance, games console or desktop computer. The location is determined by comparing data from an air pressure sensor with a pressure signature associated with an expected location.
A conditional access module receives a multimedia stream transporting multimedia content and application data forming an application to be executed in relation to the multimedia content. At reception of the multimedia stream by the conditional access module, the application data is separated from the multimedia stream by an input filter included in the conditional access module. The application data comprise a current authentication code. The input filter forwards the application data with the current authentication code to a quarantine memory associated with an application checker included in the conditional access module. The application checker verifies the current authentication code by using a reference authentication code previously acquired by the conditional access module. Upon successful verification of the authentication code, the application data is retrieved from the quarantine memory and merged by a merging module with the multimedia content previously separated by the input filter. The merging module then outputs a checked processed multimedia stream for further processing by the multimedia receiver, which executes the verified application for enhancing the multimedia content.

AN INTERFACE DEVICE FOR CONNECTING AN ELECTRONIC CHIP TO A HOST DEVICE
The present invention provides an interface device for use within a PCMCIA module allowing an interface to be made between an electronic chip on a chip card and a host device. The invention dispenses with the use of industry-standard smartcard connectors to make connection between the chip on the chip card and a printed circuit board providing the interface functionality within the PCMCIA module and makes use of a set of conductive tracks placed either within the housing of the PCMCIA module or within a specially adapted spacer or frame.
The present invention provides method for assembling a housing for a conditional access module complying with a PCMCIA Standard. The housing comprises a top cover and a bottom cover and the housing is assembled by sliding a set of tabs on the top cover into a set of cooperating tabs in the bottom cover.
It is an aim of the present invention to provide an adapter which allows a host device to be connected to a communication network without modifying the configuration of said device at hardware level by using a connector which is initially intended for the insertion of an optional card. The adapter comprises a card body (1) having a first end, fitted with contacts (3), which is intended to be inserted into a card slot arranged on the host device, and a second end, opposite the first end, which is integral with a case (2) which is intended to be linked to the communication network. The adapter has contacts (3) which extend in a first row on a face along the edge of the first end of the card body (1) and in a second row on the other face along the edge of the card body (1) so that the two rows are positioned one opposite the other with the contacts (3) of one row arranged in mirror symmetry relative to the contacts (3') of the other row. The contour of the card body (1) is symmetrical relative to an axis of symmetry (S) perpendicular to the ends of the card body (1), so as to ensure that the card body (1) is inserted into the slot of the host device in some direction or other. The case (2) has at least one cable output arranged on a face of said case (2) so that a cable portion (5) linked to said cable output is headed in a given sense and direction when the adapter is inserted into a slot in the host device, said cable portion exerting minimal traction and shear forces on the adapter.
A copy protection method and apparatus is disclosed. Various protection signals are added to a video signal in the vicinity of the color burst part of the signal. The protection signals are selected to interfere with the frequency down conversion process in the video recorder so that the color burst cannot be recorded properly. The protection signals are chosen so that when a modified video signal containing the original video signal and the protection signals has been recorded by a video recorder, playback of the modified video signal exhibits visual artefacts that are not visible before recording of the modified signal occurred. The protection signals are also used to carry digital control information for controlling the operation of a digital recorder.
The present invention relates to a host unit intended to receive at least one encrypted digital data stream and to which is connected a stream access and decryption control module CAM. The module CAM and the host unit are interlinked by an interface comprising a parallel bus through which the digital data of the stream travel and a bus through which control data travel, the two buses exchanging data bidirectionally. The module and the host unit each comprise a serial input output device and a routing device connected on the one hand to the serial input output device and on the other hand to the parallel bus so that the incoming and outgoing data transmitted serially in lines of the parallel bus are diverted to the respective serial input output devices.
An apparatus for applying an anti-copy protection signal for use with switchable head recorders, such as Video Hi-Fi recorders, is described. A high frequency pulsed signal is added to an original signal. The pulses interfere with the compensator circuitry such that the switching of the record head cannot adequately be masked on recording of a signal. On playback, the switching of the recording heads can subsequently be heard. In Video Hi-Fi recorders, the effect of the high frequency signals also interferes with the compressor-expander circuits to worsen the sound of the head switching.
A anti-copy programme signal is provided. Copies of the anti-copy video pulses made on a video recorder experience reduced quality and interference in playback making them unpleasant to watch. The uncopied signal can be viewed without any material effect on picture quality. The signal comprises a pulse added to each line of the signal throughout both the visible picture region and throughout the vertical blanking region, as well as a first modulated wave-form added to the vertical synchronization pulses of the signal and a second modulated wave-form added to several lines of the picture signal before the vertical blanking section. The presence of all three of these features together has been found to provide a surprising accumulative effectiveness in causing interference in the reproduction of the modified video signal during playback of the copied video signal, that is greater than the effectiveness provided by the different features taken separately.
