Abstract: An apparatus, system, and method are directed towards parsing and selectively encrypting different portions of data in real-time, decrypting the encrypted data in real-time, and passing the data to a media player on a client computer or other network capable device. Data in a network packet may be parsed into payload and non-payload portions. The payload portion of the packet data may then be examined to determine whether a predefined type of the data is recognized. For example, in one embodiment, the predefined data type may be media content. If the payload portion is recognized as a predefined data type, then it may be selectively encrypted. The selectively encrypted payload portion and non-payload portion of the packet may then be combined, such that the non-payload portion may be employed by firewalls, proxies, and/or NATs to route the packet towards the client computer or other network capable device.

Abstract: A network device and method are directed towards providing one time content encryption for Video on Demand (VOD) broadcast services and Networked Personal Video Recorders (NPVRs) using unique encryption keys. As content is received by the network device, it is determined whether the content is for broadcast distribution to a consumer and to be ingested into an NPVR/VOD server for possible unicast distribution. If the content is for both distributions, it is encrypted using at least one control word (CW) key. The encrypted content is then copied into at least two streams, with the CW being encrypted with at least two different keys, one for broadcast distribution, and one for NPVR Programs. One stream may then be ingested by the NPVR/VOD server, while the other stream may be broadcast to a consumer. The encryption keys may be provided through EMMs to a consumer based on a purchase.

Abstract: An apparatus and method for selectively encrypting portions of data sent over a network between a server and a client. The apparatus includes parsing means for separating a first portion of the data from a second portion of the data, encrypting means for encrypting only of the first portion of the data, and combining means for combining the encrypted first portion of the data with the second portion of the data, wherein the second portion of the data is not encrypted. The apparatus further includes decrypting means installed at the client for decrypting the encrypted portion of the data. The apparatus is platform independent in terms of media format and data protocol. The encryption unit encrypts data transparently to the client based on the media format. The apparatus of the invention is implemented as one of an application and a plug-in object.
