Abstract: Apparatus, systems and methods for receiving one or more input signals and providing output signals in various video, audio, data and mixed formats are described. One or more input processors receive the input signals. Each of the input processors provides one or more packetized signals corresponding to one or more of the input signals received at the input processor. Each output processor can receive one or more packetized signals and generate one or more output signals. The output signals correspond to one or more of the input signals, additional locally generated signals or data relating to the signals or any combination of such signals. Use of a packet router according to the invention allows input signals encoded as one set of packetized signals to be recombined to provide additional packetized signals incorporating the same or different combinations of the packetized signals.

Abstract: According to one embodiment, a video distribution server includes an SSD, a counter, a determination unit, an output unit, and a first and second distribution controller. The first distribution controller, when target content data of a request belongs to a preferential data, reads the target content data from the SSD. The first distribution controller buffers the read target content data in a first storage area included in the output unit, and distributes the buffered target content data to a request source. The first distribution controller caches the read target content data in a second storage area included in the output unit. When the first distribution controller receives a request for the target content data after the caching of the target content data, the first distribution controller distributes the cached target content data to a request source.

Abstract: An access platform or other network elements can include multiple line cards configured to encrypt data. The platform and/or each of the line cards may receive encryption management data that conforms to a predefined encryption management data interface. The encryption management data received by a particular line card may be generated by a conditional access system device and converted to conform to the encryption management data interface by an encryption manager. Line cards may alternatively be configured for connection to separate encryption hardware components. Line cards may include a block of field programmable gate arrays or other type of programmable hardware that can be configured to execute an encryption module.

Abstract: A method of and apparatus for efficiently providing video on demand services to a cable television subscriber. The provider system consists of two major subsystems. The first subsystem, called a video server, streams video to video on demand subscribers through the cable television network. The second subsystem, called the transaction server, performs virtually all remaining provider functions including, security, accounting, storage and spooling of video data, etc. The video server is preferably uses a Unisys CMP memory platform into which the transaction server spools requested video programs. One or more industry standard processors operating under a standard operating system stream the video data from the memory platform to the subscriber.
