Patent Application
20180103232
The present application relates generally to video transmission to a client device. More specifically, the present invention relates to efficient use of system components to transmit analog video from a small footprint device.
Providing analog video transmission from a small footprint device poses many design challenges. It is desirable to design a device, such as a security camera, that is small while maintaining robust functionality. There is therefore a need for improved systems and methods for analog video transmission in a small footprint device.
Systems and methods are disclosed for data communication and transmission of analog video from a single device. The scope of the invention is defined by the claims, which are incorporated into this section by reference. A more complete understanding of embodiments of the invention will be afforded to those skilled in the art, as well as a realization of additional advantages thereof, by a consideration of the following detailed description of one or more embodiments. Reference will be made to the appended sheets of drawings that will first be described briefly.
Aspects of the disclosure and their advantages can be better understood with reference to the following drawings and the detailed description that follows. It should be appreciated that like reference numerals are used to identify like elements illustrated in one or more of the figures, wherein showings therein are for purposes of illustrating embodiments of the present disclosure and not for purposes of limiting the same. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present disclosure.
In accordance with various embodiments of the present disclosure, systems and methods for processing and transmitting analog video are provided.
In one embodiment, the board-to-cable interface 116 receives an analog video signal 120 from the analog video source 112 and transmits the signal to the sideband pins of the USB-C port 118. The board-to-cable interface 116 also receives digital communications data 112 from data communications module 114 and provides the digital communications data 112 to pins of the USB-C port 118 in accordance with a USB standard, such as USB-A.
A cable 180 communicatively couples device 110 to each of device 130 and device 150. On a first end, the cable 180 includes a USB-C jack 170 for receiving the analog video signal 120 and communications data 122 from the USB-C port 118. The cable 180 splits the wires coupled to the USB-C sideband pins from the remaining wires into a data communications portion 182 and an analog video portion 184. In one embodiment, the data communications portion 182 terminates at a USB-A connector 132, providing data communications between the first device 110 and the second device 130. The analog video portion 184 terminates with an analog video connector 152, providing an analog video signal to the third device 150.
In various embodiments, the first device 110 may be any device configured to provide an analog video signal 120 to an output through a USB-C communications port 118. In one embodiment, the first device 110 may be an image capture device, such as a surveillance video camera that may capture images in the visible, infrared or other waveforms. The second device 130 may be any device configured to communicate with the first device 110 through a USB interface. In one embodiment, the second device 130 is a server adapted to receive surveillance video data from the first device 110. The third device 150 may be any device configured to receive an analog video signal, such as a video monitor. In various embodiments, the second and third devices 130 and 150 may be combined in a single device, such as a computer system.
In various embodiments, the present disclosure allows for design of a device USB accessory board to maintain a small size. For example, a USB port in a camera may provide connection for power, digital video and control. In a conventional device, an additional port providing an analog video connection may require a larger design. In the exemplary embodiments, a USB-C connector is provided on one device, which feeds two separate connectors for a standard USB type A connection and an analog video connection.

The foregoing disclosure is not intended to limit the present disclosure to the precise forms or particular fields of use disclosed. As such, it is contemplated that various alternate embodiments and/or modifications to the present disclosure, whether explicitly described or implied herein, are possible in light of the disclosure. Having thus described embodiments of the present disclosure, persons of ordinary skill in the art will recognize that changes may be made in form and detail without departing from the scope of the present disclosure. Thus, the present disclosure is limited only by the claims.
This application claims the benefit of and priority to U.S. Provisional Patent Application No. 62/405,855 filed Oct. 7, 2016 and entitled “VIDEO TRANSMISSION SYSTEMS AND METHODS,” which is incorporated herein by reference in its entirety.
