    Abstract: Methods and systems are provided for filtering digital data formatted in packets. A filter module contains a plurality of filters and is coupled to a filter mapping module. The filter mapping module receives the identification of clusters of discrete segments of a packet and selects a group of fixed length filters to filter the clusters.

    Abstract: A hybrid method for a service provider to transmit decryption information (e.g., algorithms, parameters, keys) to clients in a secure manner and at low cost for use in decrypting broadcast services. The service provider uses a bi-directional channel (e.g., a GPRS channel) to receive service requests, authenticate clients and transmit currently valid decryption information (and, optionally, future decryption information) necessary to decrypt a broadcast service. The service provider transmits the encrypted service on a unidirectional channel (e.g., a DVB-T channel). The service provider preferably also changes the encryption of the service with time, and, as it does, transmits updated decryption information to its clients on the unidirectional channel. The updated decryption information is encrypted using the currently valid decryption information and may also include future decryption information and synchronization information.

    Abstract translation: 一种用于服务提供商以安全的方式以低成本向解密信息(例如算法,参数,密钥)传送解密信息(用于解密广播服务)的混合方法。 服务提供商使用双向信道(例如,GPRS信道)来接收服务请求,认证客户端并发送解密广播服务所必需的当前有效的解密信息(以及可选地,未来的解密信息)。 服务提供商在单向信道(例如,DVB-T信道)上发送加密的业务。 服务提供者还优选地随时间改变服务的加密,并且如此,在单向信道上向其客户端发送更新的解密信息。 使用当前有效的解密信息来加密更新的解密信息,还可以包括将来的解密信息和同步信息。

    Abstract: A method and system for performing multicast broadcast handover in a wireless data network are disclosed. Each cell broadcasts administrative announcements over a logical channel to mobile terminals. The announcements indicate which multicast broadcasts are available in specified cells, as well as connection information for each cell. The mobile terminals may tune to a multicast broadcast as defined by the administrative announcements. While tuned to the multicast, the mobile terminal continues to receive administrative announcements. As the broadcast fades out or is otherwise interrupted, the mobile terminal can retune to the same multicast broadcast in another cell, based on the cell connection information included in the previously received administrative announcements.
