Abstract

Described are techniques for video bridging for conversion of IP network video streams to the USB Video Class (UVC). The conversion of IP video to UVC video can include the use of software-only conversions and hardware assisted conversions, and can be done within purpose-built “conversion” devices or as software only solutions operating within applications or drivers within the operating systems of the “end nodes”. The end-nodes simultaneously see and use multiple USB UVC video sources. The conversion process can also convert the USB UVC video control protocol to IP Video Stream control protocols.

First claim

What is claimed is:

1. A system, comprising:
first and second camera apparatuses coupled to an internet protocol (IP) network;
a bridging apparatus having a first connection coupled to the IP network and a second connection with a peripheral bus; and
a user device comprising a memory and a processor, wherein the processor executes an operating system that natively supports video communication over the peripheral bus; and wherein the bridging apparatus transcodes video data between the IP network and the peripheral bus, wherein the user device uses its own peripheral bus protocol for controlling the second camera apparatus so that the user device simultaneously accesses and controls video streams provided by the first and second camera apparatuses while the first and second camera apparatuses are being controlled by a uniform, single control protocol.

2. The system of claim 1 , wherein the first and second camera apparatuses are controllable using an Open Network Video Interface Forum (ONVIF) pan-tilt-zoom (PTZ) protocol.

3. The system of claim 1 , wherein the transcoding by the bridging apparatus comprises looking up a look-up table (LUT) for translation of a control message.

4. The system of claim 1 , wherein the bridging apparatus is configured to transcode multimedia data that includes audio data and the video data, and wherein the bridging apparatus includes a buffer for temporarily storing the audio data for alignment with video data.

5. The system of claim 1 , wherein the user device further comprises a display for displaying the video streams provided by one or both of the first and second camera apparatuses.

6. The system of claim 5 , further comprising a second user device that includes a second display for displaying the video streams, wherein the second user device uses its own peripheral bus protocol for controlling the first and second camera apparatuses so that the second user device simultaneously accesses and controls the video streams provided by the first and second camera apparatuses, and wherein the second user device displays a different configuration of the video streams provided by the first and second camera apparatuses than the first user device.

7. The system of claim 1 ,
wherein at least the first camera apparatus provides multimedia data that includes the video data; and the system further comprising
a second user device that comprises an output for outputting the multimedia data; and
wherein the first user device further comprises an output for outputting the multimedia data, the bridging apparatus transmitting the multimedia data to the first and second user devices at the same time.

8. The system of claim 1 , wherein the peripheral bus is a universal serial bus (USB).

9. The system of claim 1 , further comprising a second user device that includes a second display for displaying the video streams, wherein the second user device uses its own peripheral bus protocol for controlling the first and second camera apparatuses so that the second user device simultaneously accesses and controls the video streams provided by the first and second camera apparatuses, and wherein the second user device displays a different configuration of the video streams provided by the first and second camera apparatuses than the first user device.

10. The system of claim 1 wherein the user device is a phone, a laptop computer, or a tablet.

11. The system of claim 1 wherein at least the first camera apparatus is a video camera, a phone with a built-in camera, a laptop computer, or a tablet.
