Abstract: A method for delivering encrypted content to a subscriber terminal on-demand through a communication network is provided. The method begins when SRM receives a request for content from the subscriber terminal. In response to the request, the SRM directs a video server to transmit the content as an unencrypted transport stream to an encryptor. The packets in the unencrypted transport stream include a header with a destination address associated with the subscriber terminal. The encryptor encrypts the content in the unencrypted transport stream to generate an encrypted transport stream. The encryptor also inserts in the packet headers of the packets in the encrypted transport stream the destination address associated with the subscriber terminal obtained from the packet headers in the unencrypted transport stream. Finally, the encrypted transport stream is transmitted to the subscriber terminal over the communication network.

Abstract: The invention defines a method for leveraging the standard conditional access module interface of a digital TV receiver to deliver IPTV or other TV content without the need of a set top box. An IP-connected interface (“probe”) is used in place of a conditional access module to establish a two-way communication link between the TV and the IPTV headend or other IP content source and to deliver IP content. In an embodiment, the invention covers the specifics of content navigation without requiring any modification of the TV receiver application software or provisioning of IPTV-specific software. Content navigation is achieved by supporting a catalog/grid browsing session on the TV receiver and enabling a flat multiplex navigation, a virtual MPEG multiplex that contains the definition of several available programs but a single video and audio channel is dynamically switched to carry the selected program.

Abstract: A television event may be consumed after been stored in a mass memory of a multimedia unit, but still fully relies on the security of a secure device. A conversion of a received content aims at firstly descrambling the content using control words included in entitlement control messages and immediately re-encrypting the descrambled content by a unique key generated specifically for this content. Access conditions attached to the entitlement control message containing the control word are temporarily stored and once the decryption is terminated, the secure device produces an information block. This information block containing for example access conditions and an identifier of the content is either stored into a secure memory of the secure device or stored in the mass memory with the encrypted content. The unique key is made up of a combination of a root key specific to the secure device and the information block.

Abstract: The present invention makes use of techniques such as those described by Boneh and Franklin to allow for the realization of a pseudo-asymmetric encryption scheme whereby one public encryption corresponds to a plurality of private decryption keys. This scheme therefore provides a solution to the problem of inefficient use of bandwidth in asymmetrical encryption schemes which inherently require that a plurality of encryptions of data be broadcast to a plurality of receivers. The invention further ensures that the advantage of traceability, typical found in asymmetric encryption schemes, is maintained due to the characteristic that each receiver uses a unique traceable decryption key. The traceability thus achieved by the present invention allows for the revocation of a security module which has been involved in the abusive use of conditional access data, particularly by means of clones of security modules whose security has been compromised.

Abstract: The present invention proposes a solution to prevent a program flow in a processing unit from being modified with respect to an intended program flow, thereby ensuring that important steps such as verifying or authenticating are not bypassed. The invention is particularly aimed at security modules within receiver/decoders in a pay-TV system and involves performing a set of predetermined operations during the processing of entitlement management messages and/or entitlement control messages, said operations being redundant with respect to the normal processing of said messages while leading to the calculation of keys which can then be used to verify that the intended program flow has been respected.

Abstract: Advertising is marked with a code in a way which makes it difficult to fool the system. The advertising is marked with a code at the time the advertising is produced. Then, when the advertising is broadcast, the code on the advertising is analyzed. Different security measures can be used, including producing the code in the closed captioning so that many different people can see the code, or comparing codes in one part of the signal with a code in another part of the signal. Measures are taken to prevent the code from being used to detect commercials. According to another part of this system, a paradigm for a clearinghouse is disclosed in which the user signs up with the clearinghouse, obtains a line of credit, and the advertiser, the agency, and the ad producer also subscribe to the service. When the ad is actually aired, the payment can be automatically transferred.
