Smart card authenticated download
Systems and methods provide a targeted and secure software image or other data to a television receiver. The data item can be provided to the smart card through a television service provider distribution system in blocks of data that are small enough to be processed by the smart card. For each block of data, the smart card can decrypt the block of data with a global network key, generate a partial hash representing the block of data, update a full hash with the partial hash, encrypt the block of data with a dynamically generated item key, and transmit the encrypted block of data to the television receiver. Once complete, the smart card can security check the software image including an integrity check using the full hash. If the security check passes, the smart card can transmit the dynamically generated item key to the television receiver.
Signal processing apparatus and methods
A unified system of programming communication. The system encompasses the prior art (television, radio, broadcast hardcopy, computer communications, etc.) and new user specific mass media. Within the unified system, parallel processing computer systems, each having an input (e.g., 77) controlling a plurality of computers (e.g., 205), generate and output user information at receiver stations. Under broadcast control, local computers (73, 205), combine user information selectively into prior art communications to exhibit personalized mass media programming at video monitors (202), speakers (263), printers (221), etc. At intermediate transmission stations (e.g., cable television stations), signals in network broadcasts and from local inputs (74, 77, 97, 98) cause control processors (71) and computers (73) to selectively automate connection and operation of receivers (53), recorder/players (76), computers (73), generators (82), strippers (81), etc. At receiver stations, signals in received transmissions and from local inputs (225, 218, 22) cause control processors (200) and computers (205) to automate connection and operation of converters (201), tuners (215), decryptors (224), recorder/players (217), computers (205), furnaces (206), etc. Processors (71, 200) meter and monitor availability and usage of programming.
HYBRID VIDEO TIME-BANDWIDTH PRODUCT IMPROVEMENT (HVTBPI) TRANSMISSION
A video aggregator can multiplex multimedia content, the multiplexed multimedia content being directed to a plurality of customer premises equipment, and aggregate the multiplexed multimedia content into a reduced number of broadcast channels to release at least one of bandwidth and radio frequency spectrum, not included in the reduced number of broadcast channels, for other applications. A system controller can electronically control delivery of the aggregated and multiplexed multimedia content to the plurality of customer premises equipment within the reduced number of broadcast channels, receive a request for unavailable other content, and electronically control delivery of the unavailable other content. A system processor can determine whether other content, the other content being at least one of not currently being broadcast via the aggregated and multiplexed multimedia content into a reduced number of broadcast channels and not stored by a particular customer premises equipment, is unavailable to the particular customer premises equipment to determine the unavailable other content, and formulate the request for the unavailable other content if the other content is determined to be unavailable.
Systems and methods for managing local storage of on-demand content
On-demand systems and methods are provided to manage locally-stored on-demand content. A user's equipment controls the deletion of and/or access to on-demand content from a local storage device based on constraining criteria that may include rental conditions, dynamic factors, and keys.
Image processing apparatus and control method thereof
An image processing apparatus includes: a central processing unit (CPU) configured to process data; a random access memory (RAM) which includes a first storage area which stores the data processed by the CPU and a second storage area different from the first storage area; and a RAM controller configured to authorize the CPU to access the first storage area and block the CPU from accessing the second storage area so that the data loaded to the second storage area can be prevented from being copied by the CPU.
STRONG AUTHENTICATION OF CLIENT SET-TOP BOXES
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.
HYBRID VIDEO TIME-BANDWIDTH PRODUCT IMPROVEMENT (HVTBPI) RECEPTION
The disclosure is directed to an apparatus that can include a first receiver, a second receiver, a video demultiplexor, and an assembly engine. The first receiver can receive multiplexed multimedia content and advertisement, the multiplexed multimedia content and advertisement being received over a reduced number of broadcast channels to release at least one of bandwidth and radio frequency spectrum, not included in the reduced number of broadcast channels, for other applications. The second receiver can receive unavailable other content, the unavailable other content being other content that is different from the multiplexed multimedia content and advertisement and unavailable to the apparatus. The video demultiplexor can demultiplex the received multiplexed multimedia content and advertisement from the reduced number of broadcast channels to produce a multimedia content and an advertisement and store, within a storage device, the multimedia content and the advertisement.
Content management
According to an example embodiment of the present invention, there is provided an apparatus comprising at least one secure element configured to store at least two credentials, and at least one processing core configured to cause a first one of the at least two credentials to be employed to decrypt a first encrypted content to produce a first decrypted content, to cause a second one of the at least two credentials to be employed to decrypt a second encrypted content to produce a second decrypted content, and to cause the first decrypted content be provided to a first rendering device over a first secured tunnel connection, wherein an endpoint of the first secured tunnel connection resides in the apparatus.
Strong authentication of client set-top boxes
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.
IMAGE PROCESSING APPARATUS AND CONTROL METHOD THEREOF
An image processing apparatus includes a storage, a receiver configured to receive a transport stream from a source device, and a processor. According to an aspect, the processor is configured to decrypt encrypted content data obtained from the transport stream received by the receiver, generate index information based on the decrypted content data where the index information generated includes at least one reference corresponding to the encrypted content data to be referenced to display an image of the content data, and store the encrypted content data in association with the index information in the storage.
