    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 compression context for a plurality of packets is established with a receiving device. Each of these packets is associated with one or more reliable multicast protocols, such as the Layered Coding Transform (LCT) protocol, the Asynchronous Layered Coding (ALC) protocol, the FLUTE protocol, the MUPPET protocol, and the NACK-Oriented Reliable Multicast (NORM) protocol. Upon establishment of the compression context, a compressed packet is generated for one of the plurality of packets and transmitted to the receiving device. The compressed packet has a reduced number of bits in its header. Upon receipt, the receiving device decompresses the compressed packet based on the compression context.

    Abstract translation: 用接收设备建立多个分组的压缩上下文。 这些分组中的每一个与一个或多个可靠的多播协议相关联,例如分层编码变换(LCT)协议,异步分层编码(ALC)协议,FLUTE协议,MUPPET协议和面向NACK的可靠多播( NORM)协议。 在建立压缩上下文时,为多个分组之一生成压缩分组,并发送给接收设备。 压缩包在其头部中具有减少的比特数。 在接收到接收设备时,基于压缩上下文来解压缩压缩的分组。
