Abstract: A network device (ND) includes a first interface controller operable to transfer data between the ND and a host processing unit (host), a second interface controller operable to transfer data between the ND and the host, a network interface configured to interface the ND with a network, and a control unit operable to: receive incoming data from the network, process the incoming data, and transmit the processed incoming data to the host through the second interface controller; or, receive outgoing data from the host through the second interface controller, process the received outgoing data, and transmit the processed outgoing data to the network. The first interface controller, the control unit, and the network interface are together operable to enable the host to transmit and/or receive other data to and/or from the network and the first interface controller. The host and the control unit share a same network address.

Abstract: A Network Device (ND) may be configured to enable secure digital video streaming for HD (high definition) digital video systems over a standard network. The ND may operate in at least one of two modes, a co-processor mode and a stand-alone mode, and may provide at least three high level functions: network interface control (NIC), video streaming offload (VSO), and stand-alone video streaming (SVS). To seamlessly execute the VSO functionality, the ND may be configured to have two network stacks running synchronously on a single network interface having a single network address. The two network stacks may share the data traffic, while the Host network stack may act as a master, and configure the ND network stack to accept only specifically designated traffic, thus offloading some of the data processing to the processor configured in the ND.
