Abstract: An implementation of streaming video in HTML (Hypertext Markup Language) Web pages combines video signals in MPEG digital television format with Internet World Wide Web pages in HTML format. Internet streaming video is transcoded into MPEG-2 digital video format and multiplexed along with other MPEG-2 digital video signals for transport within a multiple channel digital video system. A navigational control map, transmitted from the headend to the CATV set-top box in a fixed location i n the MPEG-2 video data steam, permits the CATV set-top to find the requested video clip in a predetermined Packet Identifier of the MPEG-2 data stream. The viewer controls the video clip (e.g., play, pause, resume, restart etc.) during the session. In the two-way embodiment, the set-top transmits control commands to the headend, which implements the command in MPEG-2 video.

Abstract: In a telecommunication switching system the telecommunication software is implemented by means of independent software components referred to as objects. The objects communicate with each other by messages and symbolic names only. A runtime system includes a runtime linker which registers the systems components and records a data pointer to the components data. To communicate with another object, a source object transmits an executable expression, called a message, to the runtime system. The message includes the symbolic name and the identity of the method of the destination object. The runtime system serves only a single processor or group of objects and calls the destination object, by means of the identity of the method and the data pointer if the destination object is within the group of objects served by the runtime system. In the case a destination object is located on another processor, the runtime system will broadcast the message to other processors.

Abstract: A telecommunication and development system for the switching of voice and data under computer control in a customer programmable environment that allows real-time modification of communication services. The computer program controlling the system is written in a nonprocedural language that allows for the direct control of the telecommunication system on the basis of state definition, event definition, and action definition. Program scripts define a particular feature, and each script consists of a plurality of triples that automatically respond to the system state and signal information to execute the necessary actions to provide part of a feature to the telecommunication system. During provision of telecommunication services, a customer can add new features that not only add new operations to the system, but modify existing operations without interfering with the present operation of the system.

Abstract: A software system written in a nonprocedural language for controlling a telecommunication system in which an internal software signal is generated when a state is exited and another internal signal is generated when a state is entered to control common operations for the state transitions. For each state, a group of instructions written in the nonprocedural language is autonomously executed in response to the exit signal to perform common exit operations for that particular state. A second group of instruction is autonomously executed in response to the entrance signal to perform common entrance operations for that particular state. Various services performed by the telecommunication system are written in scripts of groups of instructions called triples. Each triple has an event definition defining the signal that the triple will respond to and a state definition defining the state in which the system must be in before the triple can respond.

Abstract: A telecommunication system for the switching of voice and data controlled by a computer executing a nonprocedural language that allows for the explicit control of interaction between features by the program scripts executing the programs. The program scripts are written in the nonprocedural language that allows for a state definition, an event definition, and an operation definition. The triples automatically respond to the system state and system signal to execute the necessary actions to control the telecommunication system. During the run time of the system, a script whose triples implement a particular feature can control whether or not features of lower precedence are allowed to be implemented by determining whether or not allow the continuation of the processing of the system signals to the scripts of lesser precedence. In addition, a script can control its own deactivation until later conditions are met that allow the deactivation of the script.
