Abstract
Abstract Computer data provided according to a first data protocol, such as the Internet protocol, is communicated over a digital television broadcast network using a second data protocol such as MPEG2. The computer data in the first data protocol is encapsulated in at least one data stream for distribution in conformance with the second data protocol. The at least one data stream encapsulating the computer data is multiplexed with a plurality of data streams conforming to the second data protocol for transmission over the network, which may be a cable or satellite television network. The data stream encapsulating the computer data is received from the network according to the second data protocol, and processed in accordance with the second data protocol to recover the computer data in the first data protocol. A prioritization scheme is provided wherein different messages in the first data protocol are prioritized in the output multiplex according to at least one of source address, destination address, data type and connection type.
