Abstract: Various embodiments are directed towards employing a container and communication protocol proxy component within a client device to receive securely real-time streamed, progressively downloaded, or adaptively streamed container over a network using one container and communication protocol, and to securely decrypt the container and provide it to a media player using a different container and communications protocol. In one embodiment, the container is in Flash Video (FLV) file format. A browser or the media player on the client device may be used to request the container. The requested container is sent over one communication protocol and intercepted by the container and communication protocol proxy component. The container may be received as selectively encrypted container. The container and communication protocol proxy component then may enable decryption of the container and providing of it to the media player using another container and communication protocol combination.

Abstract: A system, apparatus, and method are directed towards managing entitlement/right revocation and delivery to be performed within a non-addressable media network. Such networks may include for example a client device behind a network address translation (NAT) device, employs non-addressable satellite components, or so forth. A server notifies clients that entitlements, revocations, or the like are available by sending a request for communications with the client. The client initiates a connection to receive the entitlements, or the like, and then disconnects from the server. If the client fails to initiate a connection, the server may continue to send a request for a connection, or even change encryption keys to the content to prevent access by the client. In one embodiment, failure to receive an acknowledgement response from the server of a connection with the client, or from the client, may result in invocation of a revocation failure action.

Abstract: A system, apparatus, and method are directed towards allowing ingestion of encrypted content into such as a VOD server, or PVR, or the like by selectively encrypting portions of a content stream based on various selection rules. In one embodiment, the selection rules include leaving selected portions of the content stream unencrypted, including packets that include a PES header; or video packets that include various trick play data such as picture start, GOP start, sequence start, sequence end data; PIDs associated with a PAT, PMT, or the like; while other portions of the content stream may be encrypted, including video and/or audio PIDs, or other video and/or audio portions. In still another embodiment, Entitlement Control Messages (ECMs) may be inserted that employ an encryption/decryption key rotation scheme, such as odd and/or even scrambling control bit structures, which may also be rotated based on a variety of conditions.

Abstract: There is disclosed a process for encrypting a data stream to secure the data stream for single viewing and to protect copyrights of the data stream. Specifically, there is disclosed a process for protecting streaming multimedia, entertainment and communications in an Internet-type transmission. There is further disclosed a streaming server component operably connected with a streaming server that interacts with a client system to affect the inventive process.

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.
