VIDEO TRANSMISSION SYSTEMS AND METHODS
A system includes a video source providing an analog video signal, a data communications module, providing digital data communications, a USB-C port configured to receive a USB-C jack, and a board-to-cable device configured to map the analog video signal to sideband pins of the USB-C port, and map the digital data communications to the USB-C pins in accordance with a USB protocol. The a cable for use in the system may include a USB-C connector at a first end, an analog video portion coupled to sideband pins of the USB-C connector, and a digital data portion coupled to a subset of pins of the USB-C connector, the subset of pins selected in accordance with a USB protocol.
1 . A method for transmitting analog video and digital data comprising:
receiving an analog video signal;
receiving digital data;
transmitting the analog video signal through sideband pins of a USB-C port; and
transmitting the digital data through the USB-C port in accordance with a USB communications protocol.
2 . The method of claim 1 wherein the analog video signal is a composite video signal.
3 . The method of claim 1 further comprising transmitting the analog video signal and digital data through a single USB-C connector.
4 . The method of claim 3 further comprising providing a communications cable coupled to the USB-C connector.
5 . The method of claim 4 wherein the communications cable splits into a sideband portion and a digital data portion.
6 . The method of claim 5 wherein the sideband portion is coupled at a terminal end to an analog video connector.
7 . The method of claim 5 wherein the digital data portion is coupled at a terminal end to a USB connector.
8 . A system comprising:
a video source providing an analog video signal;
a data communications module, providing digital data communications;
a USB-C port, configured to receive a USB-C jack; and
a board-to-cable device configured to map the analog video signal to sideband pins of the USB-C port, and map the digital data communications to the USB-C pins in accordance with a USB protocol.
9 . The system of claim 8 wherein the video source is an image capture device.
10 . The system of claim 8 wherein the analog video signal is a composite video signal.
11 . The system of claim 8 further comprising a cable coupled to the USB-C port, the cable comprising:
a USB-C connector at a first end;
an analog video coupled to sideband pins of the USB-C connector; and
a digital data portion coupled to a subset of pins of the USB-C connector, the subset of pins selected in accordance with a USB protocol.
12 . The system of claim 11 wherein the analog video portion includes an analog video connector at a terminal end.
13 . The system of claim 11 wherein the digital data portion includes a USB connector at a terminal end.
14 . A cable comprising:
a first end including a USB-C connector; and
a second end split into an analog video portion and a digital data portion, wherein the analog video portion is coupled to sideband pins of the USB-C connector, and wherein the digital data portion is coupled to a subset of pins of the USB-C connector in accordance with a USB protocol.
15 . The cable of claim 14 wherein the analog video portion includes an analog video connector at a terminal end opposite the USB-C connector.
16 . The cable of claim 14 wherein the digital data portion includes a USB-A connector at a terminal end opposite the USB-C connector.
17 . A method of operating the cable of claim 16 comprising:
coupling the USB-C connector to a first device;
transmitting via the first device through the sideband pins of the USB-C connector, an analog video signal; and
transmitting via the first device through a subset of the remaining pins of the USB-C connector, digital data.
18 . The method of claim 17 further comprising coupling the analog video connector to a second device, the second device receiving the transmitted analog video signal.
19 . The method of claim 17 further comprising coupling the USB connector to a third device, the third device receiving the transmitted digital data.
