Abstract:
The present invention relates to a method for simultaneous viewing and recording of separate conditional access contents in an image display device. The method for processing at least a first program content and a second program content is proposed, said program contents being selected from at least a first transport stream and a second transport stream, the method for processing at least a first program content and a second program content being applicable by an image display device in communication with a first conditional access module and a second conditional access module, said image display device being further in communication with a first tuner to receive the first transport stream and a second tuner to receive the second transport stream.

Abstract:
The present invention may be deployed in a system comprising a Common Interface Conditional Access Module (CICAM) connected to a host device according to a Common Interface Standard. In keeping with the standard, the common interface comprises a command interface and a transport stream interface. The invention allows for commands to be sent across the common interface at a data rate which is substantially higher than the data rate allowed for commands to be sent according to the Common Interface Standard.
Abstract:
La présente invention concerne une unité hôte destinée à recevoir au moins un flux de données numériques encryptées à laquelle est connecté un module CAM de contrôle d'accès et de décryptage du flux. Le module CAM et l'unité hôte sont reliées entre eux par une interface comportant un bus parallèle dans lequel transitent les données numériques du flux et un bus dans lequel transitent des données de commande, les deux bus échangeant des données de manière bidirectionnelle. Le module et l'unité hôte comprennent chacun un dispositif d'entrée sortie série et un dispositif d'aiguillage connecté d'une part au dispositif d'entrée sortie série et d'autre part au bus parallèle de sorte que les données entrantes et sortantes transmises en série dans des lignes du bus parallèle sont déviées vers les dispositifs d'entrée sortie série respectifs.
Abstract:
An apparatus may include circuitry, a cryptographic module, and a key store. The circuitry may hold a private key associated with first media information. The cryptographic module may operate on the private key to generate a number of first control keys for decrypting the first media information. The key store may hold the number of first control keys from the cryptographic module. In some implementations, the key store may include sufficient storage to store more than one control key from each of a number of different crypto modules. In some implementations, the key store may receive multiple control keys simultaneously or nearly so. In some implementations, the key store may output multiple control keys simultaneously, or nearly so, for decrypting multiple streams of media information at the same time.
Abstract:
The present invention is directed towards providing a partial dual-encrypted stream in a conditional access overlay system. The headend equipment includes an aligner, identifier, and remapper (AIR) device (615) that receives a clear stream and one or two encrypted streams, where the two encrypted streams have been encrypted by two different encryption schemes. The AIR device (615) identifies critical packets associated with the clear stream and subsequently allows two encrypted streams to pass and drops the critical packets of the clear stream. A multiplexer (640) then combines a percentage of the non-critical packets of the clear stream and the critical packets of the two encrypted streams to provide the partial dual-encrypted stream.
Abstract:
An exemplary content delivery system for delivering pre-encrypted content to a first subscriber terminal includes an off line encryption system configured to generate the pre-encrypted content using a control word, a caching system configured to store the pre-encrypted content and transmit the pre-encrypted content to the first subscriber terminal, a first conditional access system configured to allow a number of subscriber terminals to decrypt the pre-encrypted content, a second conditional access system configured to allow the first subscriber terminal to decrypt the pre-encrypted content, and a first encryption renewal system associated with the first conditional access system. The first encryption renewal system is configured to authorize the second conditional access system to allow the first subscriber terminal to decrypt the pre-encrypted content. An exemplary method for delivering pre-encrypted content to a first subscriber terminal includes generating the pre-encrypted content using a control word, transmitting the preencrypted content to the first subscriber terminal, and using an encryption renewal system associated with a first conditional access system to authorize a second conditional access system to allow the first subscriber terminal to decrypt the pre-encrypted content.
Abstract:
The present invention is suitable for use in a partial dual encrypted system. The present invention allows for two different decryption devices (e.g., an incumbent, or first, set-top and an overlay, or second, set-top) to be located in a single system having an incumbent encryption scheme and a second encryption scheme. Each set-top is designed to decrypt the first or second proprietary encryption schemes, respectively. In accordance with the present invention, the second set-top utilizes a novel program map table to ensure that the second set-top chooses correct elemenentary streams in the partial dual-encrypted stream (i.e., a combined stream including a first encrypted stream, a second encrypted stream, and a clear stream) for a desired program.
