    • Delivery of conditional access (CA) data to a receiver (410) that is able to connect to a plurality of scrambled programs. Conditional access for a current channel is handled (310) using standard ECMs delivered with the channel. In parallel, the receiver (410) retrieves (320) an ECM for a separate stream comprising control words for every channel. The control word of this ECM is used to descramble (330) the separate stream to access the control words for every channel. In a preferred embodiment, these control words are super-encrypted using channel keys and the receiver is only able to obtain channel keys for channels for which it has access rights. In case the control words are super-encrypted, they are decrypted (340). Upon channel change, the relevant retrieved control word is used to descramble (350) the new channel. Also provided is a receiver device (410) and a transmitter device (420). According to a variant, the control words received in the separate stream is treated only upon a change of channel. The invention enables a reduction or removal of the CA delay when switching between channels.
    • 将条件访问(CA)数据传送到能够连接到多个加扰程序的接收器(410)。 使用通道随附的标准ECM处理(310)当前通道的条件访问。 并行地,接收机(410)检索(320)用于包含用于每个信道的控制字的单独流的(702)ECM。 该ECM的控制字用于解扰(330)单独流以访问每个通道的控制字。 在优选实施例中,使用信道密钥对这些控制字进行超级加密,并且接收机只能获得具有访问权限的信道的信道密钥。 在控制字被超加密的情况下,它们被解密(340)。 在频道改变时,使用相关检索到的控制字来解扰(350)新频道。 还提供了接收机设备(410)和发射机设备(420)。 根据一个变型,在单独流中接收的控制字仅在频道改变时被处理。 本发明能够在通道之间切换时减少或消除CA延迟。

    • Method for retransmission of a multimedia stream from a video transmitter via an intermediary storage server, this multimedia stream comprising packets coding independent images, and packets of dependent images, the multimedia stream comprising a continuous component and a discontinuous component, the intermediary server storing this multimedia stream in a memory characterized in that it comprises the following steps: - the step for the intermediary server to receive a request for retransmission of the multimedia stream transmitted - the step for the intermediary server to select an independent image packet stored in its memory in order to begin a retransmission of the received multimedia stream and - the step for the server to accelerate the retransmission of the multimedia stream received later than the independent image packet selected omitting to retransmit the dependent image packets until the accelerated part of the stream retransmitted by the intermediary server is synchronized with the stream received by this intermediary server, wherein the retransmission of the discontinuous component is accelerated while the retransmission of the continuous component is carried out, without acceleration, from a continuous packet stored in the server in such a way that the continuous component is synchronized with the discontinuous component retransmitted when the stream retransmitted by the intermediary server is synchronized with the stream received by this intermediary server.
