Abstract: A service gateway provides a proxy between a client protocol and a plurality of standard communication protocols. The service gateway provides asymmetrical routing, data compression and encryption to optimize client processing power and communication link bandwidth. The service gateway enables content translation between clients and service providers. The service gateway keeps track of client available memory and sequence numbers in messages to generate error codes when applicable. A store and forward message capability is provided along with abstract session identifiers. The service gateway supports user datagram protocol.

Abstract: Methods and apparatuses relating to processors that contextually optimize instructions at runtime are disclosed. In one embodiment, a processors includes a fetch circuit to fetch an instruction from an instruction storage, a format of the instruction including an opcode, a first source operand identifier, and a second source operand identifier; wherein the instruction storage includes a sequence of sub-optimal instructions preceded by a start-of-sequence instruction and followed by an end-of-sequence instruction.

Abstract: A hierarchical security policy that can be imposed by a policy maker upon a class of entities in an interactive television environment. A general policy is defined for a class of entities. A specific policy may also be defined for any subclass of entities, such as the grouping of advertisements or programs. A specific policy may be defined for any given entity, such as a specific television program as an exception to a class.

Abstract: A method and apparatus for providing digital services in a peer-to-peer environment in which broadband back-channel communications from a client to a central server and broadband peer-to-peer (client-to-client) communications are not available. A plain old telephone service (POTS) is utilized to enable relatively slow modems associated with client set top boxes to communicate latency tolerant information with one another at relatively low data rates. An application is broadcast from a head end server to client device subscribers. The application creates or includes a data structure comprising a state for an interactive game, bulletin board or other application in which a number of users are interested in being apprised of changes to the data structure representing the game or bulletin board.
