摘要： A selective encryption encoder consistent with certain embodiments of the invention has vertical and/or horizontal stripes encrypted. In one embodiment, packets are examined in the digital video signal to identify a specified packet type, the specified packet type being both packets carrying intra-coded data representing a pattern of horizontal stripes across an image and packets carrying intra-coded data representing a pattern of vertical stripes across an image. The packets identified as being of the specified packet type are encrypted using a first encryption method to produce first encrypted packets. These first encrypted packets are then used to replace the unencrypted packets in the digital video signal to produce a partially encrypted video signal. The packets of the specified type can also be multiple encrypted and replaced in the data stream to produce a multiple encrypted video data stream. This abstract is not to be considered limiting since embodiments consistent with the present invention may incorporate more, fewer or differing elements than mentioned in this abstract.
摘要翻译：与本发明的某些实施例一致的选择性加密编码器具有加密的垂直和/或水平条纹。在一个实施例中，在数字视频信号中检查分组以识别指定的分组类型，所指定的分组类型是两个分组，这两个分组类型是携带表示跨越图像的水平条带模式的帧内编码数据的分组，以及携带表示模式的帧内编码数据的分组横跨图像的垂直条纹。使用第一加密方法对被标识为具有指定分组类型的分组进行加密，以产生第一加密分组。然后，这些第一加密分组用于替换数字视频信号中的未加密分组，以产生部分加密的视频信号。指定类型的数据包也可以在数据流中进行多重加密和替换，以产生多个加密的视频数据流。该摘要不被认为是限制性的，因为与本发明一致的实施例可以包含比本摘要中提及的更多，更少或不同的元件。

摘要： A multimedia stream head end includes a legacy conditional access (CA) device that fully encrypts the stream using legacy keys. A copy of the stream is sent to a secondary CA device that encrypts only critical packets in the stream using secondary keys to render a partially encrypted stream. The critical packets in the fully encrypted stream from the legacy CA device are obtained and inserted next to the corresponding critical packets in the partially encrypted stream. Thus, only critical packets are encrypted, with encrypted versions being generated by both the legacy CA and secondary CA without the legacy CA knowing which of the packets that it encrypts are “critical”.

摘要： A CableCARD device for manipulation of a stream of data has an inband data input for receiving a stream of data from a host, the stream of data having a plurality of packets each having a packet identifier (PID) associated therewith, wherein the stream of data further has encrypted packets. A PID remapper selects certain of the packets for remapping of the packet identifiers associated with the selected packets, and remaps the packet identifiers of the selected packets so that the packets are associated with a new packet identifier. A decrypter decrypts the encrypted packets. An encrypter re-encrypts the decrypted packets. An inband data output sends the data stream with remapped packet identifiers back to the host. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

The specified packet type includes packets carrying data representing a video slice wherein the video slice contains a larger amount of data than a threshold amount of data. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. Packets are sent and received to and from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method.
