    • The invention relates to a method and an apparatus for defining entry points for a data stream, in particular a stream of audiovisual information. Entry points in the stream are defined at a predetermined interval. This may be a time interval, a byte interval or any other interval. It is an object of the invention to provide an entry point table having a limited size. This object is achieved by increasing the interval between entry points if the table exceeds a predetermined size. This size may be defined in bytes, in the number of entry points or even in the number of sub-tables. After redefinition of the interval between entry points, entry points are redefined. The invention also relates to an apparatus for defining the entry points and to a record carrier with a data stream incorporating entry points defined by the method according to the invention.
    • 本发明涉及一种用于定义数据流,特别是视听信息流的入口点的方法和装置。 以预定间隔定义流中的入口点。 这可以是时间间隔,字节间隔或任何其他间隔。 本发明的目的是提供一种具有有限尺寸的入口点表。 如果表超过预定大小,则可以通过增加入口点之间的间隔来实现此目的。 这个大小可以以字节,进入点数量或子表数量来定义。 重新定义入口点之间的间隔后,重新定义入口点。 本发明还涉及一种用于定义入口点的装置和具有包含由根据本发明的方法限定的入口点的数据流的记录载体。

    • A method of adding a new device (221) to a device group (210), the device group (210, 220) including a plurality of devices, wherein each device in the device group possesses a device group key and device keys of all other devices in the device group for encryption of messages, except its own device key. The method includes: establishing a secure connection between the new device (221) and a first device (211) in the device group (210); sending, by the first device (211) in the device group (210), the device group key and device keys of all other devices (212, 213, . . . , 21N) in the device group (210) to the new device (221); distributing, by one of the other devices (212, 213, . . . , 21N) in the device group (210), the device key of the first device (211) in the device group (210) to the new device (221); generating and distributing, by one of the devices (211, 212, 213, . . . , 21N) in the device group (210), a device key of the new device (221) to all other devices (211, 212, 213, . . . , 21N) in the device group (210). This approach is also generalized to k-resilient schemes.
    • 一种将新设备(221)添加到设备组(210)的方法,所述设备组(210,220)包括多个设备,其中设备组中的每个设备具有设备组密钥和所有其他设备组的设备密钥 设备组中的设备用于加密消息,除了自己的设备密钥。 该方法包括:在新设备(221)和设备组(210)中的第一设备(211)之间建立安全连接; 通过设备组(210)中的第一设备(211)将设备组(210)中的所有其他设备(212,213,...,21N)的设备组密钥和设备密钥发送到新设备 (221); 通过设备组(210)中的其他设备(212,213,...,21N)之一将设备组(210)中的第一设备(211)的设备密钥分发到新设备(221) ); 通过设备组(210)中的一个设备(211,212,213,...,21N)生成和分发新设备(221)的设备密钥到所有其他设备(211,212,213) ,...,21N)在设备组(210)中。 这种方法也推广到k弹性方案。
