Transport multiplexer management and control

Abstract

A system and method of multiplexing data into an MPEG transport stream are described. In particular, an IP packet is examined to determine if it is a multicast IP packet. If so, the IP packet is repackaged into one or more MPEG packets for transmission in the MPEG transport stream.

15 claims: 3 independent, 12 dependent

  1. 1
    Claims of equivalent WO 02087158 A2 What is claimed is:1. A control system that uses SNMP to remotely confrol broadband communications hardware via a network, the communications hardware comprising a plurality of processor boards that perform content stream manipulation and configuration task firmware for configuring and controlling the processor boards, the control system comprising: a user interface for presenting information to a control system operator and for receiving input from the operator;an element manager communicatively linking the user interface to the network, the element manager packaging the operator input as SNMP messages and sending the messages to the SNMP agent via the network, the element manager also receiving SNMP messages from the SNMP agent via the network and providing information contained therein to the user interface for presentation to the operator;and an SNMP agent communicatively linking the configuration task firmware and the network, the SNMP agent comprising means for brokering information exchanged between the element manager and the configuration task firmware.
  2. 8
    A method of remotely controlling broadband communications hardware via a network, the communications hardware comprising a plurality of processor boards for manipulating content streams and configuration task firmware for configuring and controlling the processor boards, the method comprising:receiving content stream control commands from the operator at a first location on the network;packaging the control commands as SNMP messages;sending the SNMP messages across the network to a second location physically remote from the first location;receiving the SNMP messages at the second location;translating the received SNMP messages into confrol commands that the configuration task firmware can understand;and sending the translated commands to the configuration task firmware for execution.
  3. 15
    A method of remotely enabling an output port of a TMX chassis via a network, the TMX chassis having a multiplexer, a quantization level processor and an input processor for manipulating content streams passing therethrough to the output port, the method comprising:receiving a port enable command from an operator at a first location on the network;sending the port enable command across the network to the TMX chassis at a second location physically remote from the first location;and responsive to receipt of the port enable command, activating the targeted multiplexer first, activating the quantization level processor second;and activating the input processor third to thereby permit a content stream to pass to the output port.
