摘要： Content is distributed from a source (22) to a sink (26) only if the sink is within a predetermined distance from a source (22). Furthermore, a control signal is sent over a limited range channel to the sink and the content is then sent only if the control signal is received properly by the sink. The content (210) is also sent to the sink, but the sink cannot decode the content unless it has a proper copy of the decoding key. The control signal can be sent over a wireless channel, an IR channel, or an AC line. The content (210) is sent over the Internet, either using a standard wired channel over a wireless channel.

摘要： An apparatus for processing data and content includes at least one drive and a player (that may be implemented by software). At least some of the content is protected using a content scrambling scheme such as audio or video watermarking. The drive and player cooperate to operate in a lockable mode wherein if protected content is provided to the drive, the drive and player are interlocked so that the content is presented by the player only in accordance with consistent with protection scheme being used, and cannot be presented by any other player. Moreover, in the locked mode, protected content may not be accepted from any other drive. The drive and player are switched to an unlocked mode by presenting to the drive unprotected content.
