    • The invention relates to a protocol for disabling/erasing access rights to scrambled data. According to the invention, the access rights entered in an access control module comprise the following variables: right identification variable (R ID), action date variable (AD V) and right status variable (S V). The status variable can have one of three encoded values, namely enabled, disabled or erased right. The inventive protocol consists in: transmitting (A) at least one access right management message comprising the right identification variable (R IDX), the action date variable (AD VX) and the status assignment variable (S VX), the latter corresponding to a enabled, disabled or erased right; assigning (B) the action date (AD VX) of the message to the action date (AD V) of the right entered; and allocating (C) the status assignment variable (S VX) of the message, corresponding to an enabled, disabled or erased access right, to the status variable (S V) of the entered access right. The invention is suitable for pay television.
    • 本发明涉及用于禁止/擦除对加扰数据的访问权限的协议。 根据本发明,访问控制模块中输入的访问权限包括以下变量:正确的识别变量(R ID),动作日期变量(AD V)和右侧状态变量(S V)。 状态变量可以具有三个编码值之一,即启用,禁用或擦除。 本发明的协议包括:发送(A)包括权利识别变量(R IDX),动作日期变量(ADVX)和状态分配变量(S VX)的至少一个访问权限管理消息,后者对应于 启用,禁用或删除权限; 将消息的动作日期(AD VX)分配(B)到输入的权利的动作日期(AD V); 以及将所述消息的状态分配变量(S VX)分配(C),所述状态分配变量(S VX)对应于启用的,禁用的或被擦除的访问权限到所输入的访问权限的状态变量(S V)。 本发明适用于收费电视。

    • The invention relates to a remote control protocol for a local action to generate a command message (OM), which permits a broadcaster to control a local action in at least one receiving station comprising: a step for transmission of an authorisation message (HM) from the broadcaster to the receiving station(s) and a verification step (4) in said receiving station(s), for transmitted authenticity parameters and addresses, with regard to parameters memorised in each of said receiving stations. The invention is characterised in that the authorisation message (HM) comprises a generation action (CM), at the level of the receiving station(s), a command message (OM), calculated locally and said protocol also comprises, conditional on the verification step (4), an interpretation step (10) of said action (CM) transmitted with said authorisation message (HM) and a local generation step (20) for a command message (OM) in response to said interpretation step (10). The above finds application particularly in transmission of encoded television information (I*).
    • 本发明涉及一种用于产生命令消息(OM)的本地动作的远程控制协议,其允许广播者控制至少一个接收站中的本地动作,包括:用于从 关于存储在每个所述接收站中的参数,所述接收站的广播者和所述接收站中的验证步骤(4),用于发送的真实性参数和地址。 本发明的特征在于,授权消息(HM)包括在接收站的级别的生成动作(CM),本地计算的命令消息(OM),并且所述协议还包括以验证条件 步骤(4),响应于所述解释步骤(10),利用所述授权消息(HM)发送的所述动作(CM)的解释步骤(10)和用于命令消息(OM)的本地生成步骤(20)。 以上特别适用于编码电视信息(I *)的传输。
