摘要： Described embodiments provide systems and methods for data encryption. A server communicating data with a client can determine a level of data encryption on the data that the server is capable of handling according to resources available to the server. A level of data encryption can include a type of encryption and a strength of the type of data encryption. The server can receive a level of data encryption on the data that the client is capable of handling according to resources available to the client. The server can identify a level of data encryption with which the server and the client agree to proceed, according to the determined level of data encryption and the received level of data encryption. The server, following a predefined interval, can identify an updated level of data encryption with which the server and the client agree to proceed.

摘要： A “trusted domain” is established within which content received from a communications network, e.g., a cable TV network, is protected from unauthorized copying thereof, in accordance with the invention. In an illustrative embodiment, the trusted domain includes a device associated with a user which receives content from the cable TV network. The content may be encrypted using a content key in accordance, e.g., with a 3DES encryption algorithm before it is stored in the device. In addition, a first encrypted content key version and a second encrypted content key version are generated by respectively encrypting the content key with a public key associated with the device and another public key associated with the user, in accordance with public key cryptography. The first and second encrypted content key versions are stored in association with the encrypted content in the device storage. The encrypted content can be migrated from a first device to a second device, and can be decrypted in the second device in the second device is associated with the same user, and also provided with the second encrypted content key version.

摘要： A method includes encrypting, at a server, a media content item to form encrypted content. The method includes determining, at the server, a group of media devices associated with users that are likely to request the media content item. The method includes multicasting, without receiving a related request for the media content item from a media device of the group, the encrypted content and information from the server to the group of media devices. The information includes a usage period of the encrypted content. The method includes, receiving, at the server during the usage period, an acceptance notice of an offer for the media content item from a media device of the group of media devices. The method also includes sending, from the server to the media device, a decryption key for the encrypted content responsive to the acceptance notice.

摘要： Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.

摘要： An image generation apparatus includes: a generation unit that generates an output image in which a foreground mask image overlaps a background image, the foreground mask image having been generated based on a moving object included in an input image; an update unit that executes update processing for updating at least a partial area within the background image based on the input image; and a restricting unit that restricts reflection of the update processing in a restricted area compared to other areas, the restricted area being at least a partial area in the output image.

摘要： In a system for video data capture and sharing client devices may include one or more video cameras and sensors to capture video data and a local buffer memory for storing the captured video data. The system uses inputs from various sources, including sensors, to determine an operating mode. Based on the operating mode, video recording settings are set for the video cameras to change the size of the video data that is generated and stored in the local buffer memory to optimize its use. When the operating mode corresponds to an event of interest, the data recorded is larger, with higher video quality parameters, and when the operational mode corresponds to video footage of no interest, the data recorded is smaller, with lower video quality parameters. Additionally, other actions can be taken based on the operational mode, such as over-write the video recording parameters, notify users of likely loss of recorded data, and the like.

摘要： A system for securely providing adaptive bit rate streaming media content on-demand may include a security server of a program distributor that selects, based on a received authorized request, which of a differently encrypted stored versions of a “special segment” of the requested program to deliver to the receiving device during the transmission of the requested program. The selection may be based on a pseudo-random selection process per request for the program based on an identifier of the request associated with the remote control device. The selection of which of the differently encrypted stored versions of the “special segment” of the ordered program to deliver may be=based on the current session. The secure remote then sends to the receiving device the correct decryption key for the receiving device to decrypt the particular encrypted version selected of the “special segment” to be sent to the receiving device.

摘要： Described herein are systems and methods for securing transmission of content from a smart card in a host television receiver to a client television receiver. The smart card can receive the encrypted content stream from the television service provider, decrypt the content stream with the global network key, identify the client television receiver as the destination of the content stream, generate a unique key specific to the content stream, encrypt the unique key with a local key known to the client television receiver, encrypt the content stream with the unique key, and transmit the encrypted content stream along with the encrypted unique key to the client television receiver. The client television receiver can then receive the encrypted content stream and the encrypted unique key, decrypt the unique key, decrypt the content stream with the unique key, and transmit the content stream to a display device of the client television receiver.
