Media streaming device with gateway functionality
First Claim
1. A first device for providing a media stream to a second device, the first device comprising:
- an input interface configured to receive audio/visual signals from a media source;
a local area network interface to a local area network;
a wide area network interface to a wide area network;
a media streaming module disposed within the first device and coupled to the input interface, wherein the media streaming module is configured to create the media stream from the audio/visual signals received from the input interface, wherein the media streaming module comprises a host port interface, and wherein the media streaming module is configured to format the created media stream into network packets that are routable on at least one of the local area network and the wide area network and to encapsulate the network packets into an interface format that is compatible with the host port interface; and
a modem module disposed within the first device, wherein the modem module is coupled to the wide area network interface to provide a gateway between the local area network and the wide area network, wherein the modem module comprises an external memory interface coupled to the media streaming module via an HPI-EMIF bridge that provides a dedicated communications channel between the media streaming module and the modem module, and wherein the modem module is configured to receive the encapsulated network packets from the media streaming module via the HPI-EMIF bridge, to decapsulate the network packets, and to transmit the decapsulated network packets containing the media stream via at least one of the local area network interface and the wide area network interface.

Abstract
Various methods and devices provide place shifting of a media stream to a remote device while also providing network functionality for a local area network (LAN) and/or a wide area network (WAN). The gateway includes a media interface for receiving audio/visual (A/V) signals from the media source, as well as interfaces to the LAN and/or the WAN. A media streaming module receives the A/V signals from the media interface and processes the received A/V signals to thereby create the media stream. A modem module receives the media stream from the media streaming module via a dedicated connection, network switch and/or other connection, and transmits the media stream to the remote device via at least one of the first and second network interfaces.

5. A method for transmitting a network stream representing audio/visual signals received from a media source to a second device using a first device that communicates via a first network and a second network and that comprises a media streaming module having a host port interface and a gateway module having an external memory interface that has a direct connection to the host port interface via an HPI-EMIF bridge, and wherein the gateway module, the method comprising:
-
receiving the audio/visual signals from the media source; processing the audio/visual signals to create the media stream at the media streaming module of the first device, wherein the processing comprises formatting the media stream into network packets that are compatible with at least one of the first network and the second network and encapsulating the network packets into an interface format that is compatible with the HPI-EMIF bridge; providing the encapsulated network packets containing the media stream from the media streaming module to the gateway module of the first device via the HPI-EMIF bridge, wherein the gateway module extracts the network packets from the encapsulated network packets; and transmitting the extracted network packets containing the media stream to the second device via at least one of the first and the second networks. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
