摘要： Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The Transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.

摘要： A system includes a video-on-demand server and an authentication server. The video-on-demand server is configured to provide video-on-demand content through a broadband connection to a set-top box device. The authentication server is in communication with the video-on-demand server. The authentication server is configured to receive a request to allow access to a video-on-demand package that includes the video-on-demand content, to determine if a user is currently authorized to constantly receive a broadcast package that includes a plurality of broadcast channels related to the video-on-demand content, and to authorize a broadcast channel in the broadcast package when not currently authorized to receive the broadcast package.

摘要： A system and method for facilitating content delivery with end-to-end encryption in a network architecture using a common intermediary mezzanine distribution format (CMZF). An edge media router (EMR) device is provided in one embodiment that is configured to receive a media content asset packaged in a CMZF container structure, wherein the media content asset is provided as CMZF-formatted media content in a CMZF stream scheme. The CMZF container structure, configured to facilitate carriage of ISOBMFF track and track metadata data objects as well as sample variants in PES payload in additional elementary streams, is operative to carry each bitrate representation of the media content asset encrypted in one or more encryption schemes at a headend. Upon receipt, the EMR device is configured to repackage the media content asset to generate one or more output formats without reencrypting the media content asset for storage at a storage node and/or for downstream delivery.

摘要： A system and method for distributing content in a network architecture using a common intermediary mezzanine distribution format (CMZF). A media content asset may be processed for packaging in a CMZF container structure configured to carry each bitrate representation of the media content in a valid CMZF stream scheme, the media content encrypted in one or more encryption schemes. The CMZF formatted media content may be provided to an origin server for file-based distribution over a network which is of one of the following types; unmanaged network, managed network, or a combination thereof, and/or to a streaming network node for stream-based distribution over a over a network which is of one of the following types; unmanaged network, managed network, or a combination thereof. In one embodiment, the CMZF container structure may be based on an MPEG-TS format extended to facilitate carriage of ISOBMFF track and track metadata data objects in PES payload in additional elementary streams. In another embodiment the CMZF container structure may be based on an MPEG-TS format to facilitate carriage of sample variants in PES payload.

摘要： A device and a method for processing an image by a multimedia device that supports encryption and decryption are provided. The device includes a thumbnail image of an original image is obtained and the original image is encrypted using a first encryption scheme. An encrypted image frame is generated such that the encrypted image frame includes an identity field in which marker information is recorded between a first image field in which the obtained thumbnail image is recorded and a second image field in which the encrypted original image is recorded. The marker information indicates whether the encrypted image frame includes the second image field.

摘要： This system provides wired and/or wireless access throughout a multimedia network built on a distributed architecture which can be transparent to the user. This multimedia network includes content which is imported or generated within the network. The system allows for the content provider to determine the license status of content and update the license status of content which was previously provided by that provider. The external content can be accessed in real time or downloaded and stored within the system for later access at the convenience of the user. The usage of some content is controlled by the use of encryption and other protection methods. The system allows for storage of live video by storing the digitized video and allowing the user to control how, when and where the content is viewed. The system makes available multiple multimedia services to all users in the network or connected via the internet.

摘要： Systems and methods are provided for securely providing a media stream from a server device to a remote player via a communications network. A request for a connection is received from the remote player at the server device via the communications network. In response to the request for the connection, an authorization credential is requested from a central server via the communications network. Further, in response to the authorization credential received from the central server, the media stream between the server device and the remote player can be established over the communications network. At least a portion of the media stream may be encrypted based upon the authorization credential.
