摘要： A device configured to communicate with a second device may register a second device using one of multiple registration modes including a domain- registration mode, a device-registration mode, and a no-registration mode. The domain-registration mode allows the second device to register with the device and at least one other device registered with the device, the device-registration mode allows the second device to register with the device and with no other devices, and the no-registration mode does not allow any device to register with the device. The device receives a selection of one of the multiple registration modes and places the device in the selected registration mode.

摘要： An apparatus and method for providing at least one root certificate are disclosed. Specifically, a plurality of root certificates is received and stored. Afterwards, a request is received from a first endpoint device for a desired root certificate, where the desired root certificate is used by the first endpoint device to verify an identity of a second endpoint device. Furthermore, the first endpoint device and the second endpoint device are associated with different certificate hierarchies. The desired root certificate is then sent to at least the first endpoint device.

摘要： The systems disclosed here provide a complete standards-based end-to-end scalable system for storage, delivery and in-home distribution of digital content over IP networks using standard protocols such as Real-time Transport Protocol ("RTP") or IP-encapsulated MPEG-2 Transport Stream, or traditional MPEG-2 networks. Mechanisms are provided for receiving (65) content from one security domain, re-encrypting (73, 76) that content uniquely for a receiving device (50), persistently storing (77) that content (86), and playing back that content (86) at a later time to and within another security domain. The systems also provide the ability to stream the persistently-stored content from the initial receiving device to another device (300) that has been authenticated as part of a, e.g., home network. This allows a media server, e.g., a dual-tuner set-top box ("STB") with hard drive (170) , to deliver recorded content to any TV in the house by streaming to media clients such as STBs.
摘要翻译：这里公开的系统提供了一种完整的基于标准的端对端可扩展系统，用于使用诸如实时传输协议（“RTP”）或IP-IP的标准协议通过IP网络存储，传送和在家内分发数字内容，封装的MPEG-2传输流或传统的MPEG-2网络。提供用于从一个安全域接收（65）内容的机制，对接收设备（50）唯一地重新加密（73,76）该内容，持续存储（77）该内容（86）并且播放该内容（86） 86）在较晚时间到另一个安全域内。这些系统还提供将持续存储的内容从初始接收设备流式传输到已经被认证为例如家庭网络的一部分的另一设备（300）的能力。这允许诸如具有硬盘驱动器（170）的双调谐器机顶盒（“STB”）的媒体服务器通过流向诸如STB的媒体客户端将记录的内容传送到房屋中的任何电视。

摘要： Management of rights to content is provided within an authorized domain. In a single authorized domain, where a plurality of domain interfaces are protected using a common rights management system, a copy of particular content may be allowed to be provided on all devices or only on specific devices coupled to the domain via the interfaces. Copy protection information, for outputs to external devices not protected by the common rights management system, is also specified. Rules can be provided for specifying whether particular content may be copied or moved to another protected domain. A number of rendering devices permitted to render the content simultaneously may be specified. Content rules are provided for use in managing rights to content within an authorized domain. Such rules can be associated with content that is persistently stored by a consumer device, as well as with content that is only rendered by a consumer device.

摘要： A system provides improved security in a streaming media decoder includes decryption of encoded media information at the media layer, within a decoder component of a playback device 100. A content source, such as an MPEG-4 media stream from a network, or a file on a local storage device, etc. that contains packetized content, and supplies encrypted and encoded media information 110. A reassembler component 120 is used to initiate decryption of a nominal amount of information needed to perform further processing at the QuickTime player. Encrypted access units are sent from the reassembler 120 to the decoder 140, where the decoder 140 causes decryption of the access unit information. This approach prevents decrypted, encoded information from being transferred from the reassembler 120 to the decoder 140. Such decrypted and encoded information is especially susceptible to copying. Instead, the information transferred from the reassembler 120 to the decoder 140 is largely still encrypted. In a preferred embodiment, an Internet Protocol rights management system (IPRM) 150 is used to perform the decryption processing. The reassembler 120 makes requests of the IPRM process 150 to open a decryption session and decrypts selected packets to identify the window rendering size. The decoder 140 makes requests of the IPRM process 150 to decrypt access units within the same decryption session and to close the decryption session. Because content is encrypted on packet boundaries, and when called upon by the decoder 140, the IPRM component 150 must recreate the packet boundaries from the access unit before decryption is possible. The IPRM system component 150 is able to do so because the encrypted packets contain an IPRM header that is used by the IPRM system 150 to calculate the packet length. After decrypting all the packets, the IPRM system component 150 reconstructs the decrypted access unit and returns decrypted content to the decoder 140.
摘要翻译：一种系统在流媒体解码器中提供了改进的安全性，包括在播放设备100的解码器组件内的媒体层处对已编码媒体信息的解密。内容源，例如来自网络的MPEG-4媒体流或文件在包含分组化内容的本地存储设备等上，并且提供加密和编码的媒体信息110.重组组件120用于启动在QuickTime播放器处执行进一步处理所需的标称信息量的解密。加密的访问单元从重新组装器120发送到解码器140，其中解码器140导致对存取单元信息的解密。这种方法防止解密的编码信息从重组器120传送到解码器140.这种解密和编码的信息特别容易复制。相反，从重新组装器120传送到解码器140的信息在很大程度上仍被加密。在优选实施例中，使用因特网协议权限管理系统（IPRM）150来执行解密处理。重新组合器120使得IPRM过程150的请求打开解密会话并解密所选择的分组以识别窗口呈现大小。解码器140使IPRM处理150的请求解密相同解密会话中的访问单元并关闭解密会话。由于内容在分组边界上被加密，并且当解码器140调用时，IPRM组件150必须在解密之前从访问单元重新创建分组边界。 IPRM系统组件150能够这样做，因为加密的分组包含由IPRM系统150用来计算分组长度的IPRM头部。在解密所有数据包之后，IPRM系统组件150重构解密的存取单元并将解密的内容返回到解码器140。

摘要： A targeted discovery between a first device and a second device in a network, in particular, a WHDI network, provides discovery for an identified device or a group of identified devices. The targeted discovery determines an identifier for a second device or a group of devices that the second device belongs to, and sends a device discovery message to the second device using the identifier for the second device when the second device is configured to respond to the device discovery message if the device discovery message includes the identifier for the second device. The first device receives a response to the device discovery message from the second device and can start further communication with the second device.
