Abstract: A LED package includes a LED die, and a memory device. The memory device is arranged for holding LED data information for driving the LED die. A LED driver arrangement includes a LED package as described above, a LED driver device and a microcontroller. The microcontroller is connected to the memory device for accessing the LED data information for driving the LED die and to the LED driver for sending an output flux settings signal. The LED driver device is connected to the LED die for providing a driving signal to the LED die, the driving signal being based on the output flux in package settings signal from the microcontroller.

Abstract: Certain providers, notably of television programs, subsidize the receivers and want to avoid that these apparatuses can also be used for the services offered by other providers. On the other hand, manufacturers of these apparatuses prefer selling multipurpose apparatuses and users do not want to have several similar apparatuses, which, moreover, is cumbersome. To obtain a compromise between these contradictory requirements, it is proposed to permit reception by the apparatus of services offered by a provider other than the provider who has subsidized the apparatus, when the subscription taken out by said provider has reached a certain period or length of service.

Abstract: In a video-communication receiver provided with a deciphering module (13) used for the descrambling of scrambled transmissions, using a memory card (17) for providing information required for descrambling, service information is introduced into the receiver, for example, by replacing the memory card by a service card containing the information in a ciphered form. The receiver is provided with apparatus (29, 12, 31) for deciphering ciphered service information by means of its own deciphering module (13).

Abstract: A collective address is defined at the transmitter end, not only by the contents of a field of bits, but also by a compulsory position of said field in a word which is larger than said field. Said word is full of zeros, outside said field.To recognize in a receiver whether a message received from the transmitter is concerned,a word having the same length as the word, transmitted with its zeros, is constructed by placing several fields (CA1, CA2, . . . , CA10) end to end, each field corresponding to the contents of one of the multiple addresses concerning the receiver, and being also placed in its compulsory position,this word is compared with the received collective address word, while one similar field in the two words is searched separately for each field,the message is recognized if such a similar field is found.

Abstract: A master decoder for use with a master smart card and at least one slave decoder for use with a slave smart card are arranged in a pay tv system, wherein the master decoder receives slave entitlement messages from a central management device and writes the slave entitlement messages to the slave smart cards when the slave smart cards are inserted in the master decoder. This ensures that the slave decoders are used within close proximity of the master decoders, such as in the same dwelling.

Abstract: A receiving device comprises a pseudo-random generator (18) initialized by a control word (CW) and a memory card reader (19). In accordance with the invention, it reads control word in a table of numbers contained in a read-only memory of a memory card (17) by utilizing a mode which is chosen from among several different modes, receives from the transmitter a signal which indicates the choice made in respect of said mode at a given instant.
