  • Strategies for Integrating Plural Modes of Content Delivery
    Publication number: 20140317649
    Abstract: A hybrid system is described which allows an Internet Protocol (IP) set-top box to receive broadcast media content from a broadcast delivery infrastructure and on-demand media content from an IP delivery infrastructure. The broadcast delivery infrastructure can generate a quadrature amplitude modulated (QAM) signal, while the IP delivery infrastructure can generate an IP-based signal. The system uses a format converter to convert the QAM signal into a rights-protected signal expressed in an IP-compatible format. The format converter can be implemented as an OpenCable Unidirectional Receiver (OCUR) device.

  • Application dispatcher for seamless, server application support for network terminals and non-network terminals
    Patent number: 6163797
    Abstract: A plurality of clients are connected to one or more servers. When a client initiates a connection with a server, the server responds to the request for connection by transmitting a message back to the client to determine whether the client is a network terminal or not. The client responds with a message that is received by an application dispatcher at the server which takes one of a pair of actions based on whether the client is a network terminal. If the client terminal is a network terminal, then the application dispatcher starts a server application in the server which responds to the client application in the client. Going forward, the server application responds to all future requests from the client application. If the client is not a network terminal, then the application dispatcher initiates a client application in the server to service the client terminal application requirements.

  • Server for starting client application on client if client is network terminal and initiating client application on server if client is non network terminal
    Patent number: 5828840
    Abstract: A plurality of clients are connected to one or more servers. When a client initiates a connection with a server, the server responds to the request for connection by transmitting a message back to the client to determine whether the client is a network terminal or not. The client responds with a message that is received by an application dispatcher at the server which takes one of a pair of actions based on whether the client is a network terminal. If the client terminal is a network terminal, then the application dispatcher spawns a server application in the server which responds to the client application in the client. Going forward, the server application responds to all future requests from the client application. If the client is not a network terminal, then the application dispatcher initiates a client application in the server to service the client terminal application requirements.
