The embodiments described herein relate generally to video cables, and more specifically to systems, methods, and modes for a video cable that can convert a video signal from several different types of digital video signal protocols to a high definition multi-media interface (HDMI) protocol video signal.
In many corporate or school settings, people are often called on to give a presentation. Typically, however, a presenter using a conference room or classroom needs a variety of cables and/or connectors to connect presenter devices to the room display or projector. The presenter can carry a variety of adapters that work between his/her devices and the variety of display and projector connections. But, as has probably happened to many people, the adapters are easily lost, misplaced, or left behind.
Likewise, the facility can carry a variety of adapters. But again, the adapters are easily lost, misplaced, or accidentally packed up and walked off with. The only real solution that ensures being able to present the information is for the facilities to purchase an expensive video switching device and a number of different kinds of cables that are all permanently installed. However, those of skill in the art can appreciate that this can be an expensive solution. Thus, there is a need for a video cable that can convert a video signal from several different types of digital video signal protocols to a high definition multi-media interface (HDMI) protocol video signal.
It is an object of the embodiments to substantially solve at least the problems and/or disadvantages discussed above, and to provide at least one or more of the advantages described below.
It is therefore a general aspect of the embodiments to provide systems, methods, and modes for a video cable that can convert a video signal from several different types of digital video signal to a high definition multi-media video interface (HDMI) signal that will obviate or minimize problems of the type previously described.

The different aspects of the embodiments described herein pertain to the context of a video cable that can convert a video signal from several different types of digital video signal to an HDMI video signal, but is not limited thereto, except as may be set forth expressly in the appended claims.
For 40 years Creston Electronics Inc., has been the world's leading manufacturer of advanced control and automation systems, innovating technology to simplify and enhance modern lifestyles and businesses. Crestron designs, manufactures, and offers for sale, integrated solutions to control audio, video, computer, and environmental systems. In addition, the devices and systems offered by Crestron streamlines technology, improving the quality of life in commercial buildings, universities, hotels, hospitals, and homes, among other locations. Accordingly, the systems, methods, and modes of the aspects of the embodiments described herein, as embodied as a Dante In-Ceiling Commercial Loudspeaker, can be manufactured by Crestron Electronics Inc., located in Rockleigh, N.J.
According to further aspects of the embodiments, additional video protocols that can be used, in addition to, or in place or, those discussed above, include standard display port display signal. Standard DisplayPort (SDP) display signals are a digital display interface developed by a consortium of personal computer and chip (integrated circuits) manufacturers and standardized by the Video Electronics Standards Association (VESA). SDP signals generally originate from a video source and are connected to a display device such as a computer monitor, and it can also carry audio, and other forms of data). Another display protocol is the video graphics array (VGA) display protocol. VGA signals are analog signals, and comprise analog component red, green, blue, horizontal sync, and vertical sync (RGBHV) video signals. In the case that an HDMI cable is connected to MHVPC 100, then, in that case, MHVPC 100 acts as a simple “pass-through” device. While several example types of video signals are discussed herein, in regard to MHVPC 100, these are merely examples only, and not to be taken in limiting sense, meaning other types of video transmission protocols can be accommodated in MHVPC 100 according to aspects of the embodiments.
In operation, if multiple video/audio sources are connected to MHVPC 100, typically only one source will be active at any given time. It is typically the case, however, that a presenter generally only has one type of video/audio source operating at any given time, and so when MHVPC 100 and auto-sense switch 106 detects activity at one of its inputs, HDMI converter 108 senses the type of video input, and then retrieves the correct software algorithm automatically to convert the received signal to HDMI. Auto-sense switch 106, located in combined switch and converter device 102 senses the “live” input, and connects it to the single output that is sent to converter 108, wherein conversion to HDMI occurs. As discussed above, however, it is sometimes the case wherein an HDMI signal is input, so that MHVPC 100 acts as a through put device.
According to further aspects of the embodiments, a user selection switch can be implemented in which the user can select which input should be used as the active input to perform conversion on and output as an HDMI signal. This switch is not shown in
Once the auto-selected, or manually selected, input signal is sent to HDMI converter 108, the received, input signal is converted from its original format to an HDMI format (unless it was HDMI to begin with), and output as an HDMI video signal that is carried via HDMI cable 110 to video sink 118.
HDMI video cable connector 114 is then connected to HDMI video cable receptacle 116, which is located on HDMI video display device (video sink) 118. The now-converted HDMI video/audio signal can now be displayed on video sink 118, according to aspects of the embodiments.
Also shown as part of MHVCP 100 is pig-tail power connector 122, which is connected to connector 114. Power connector 122 is connected to pig-tail power connector receptacle (power receptacle) 124 that can be located at video sink 118. Alternatively, power connector 122 can be connected to power receptacle 124 that is part of a USB charging device (not shown).
According to aspects of the embodiments, each of switch 106 and converter 108 receive their power from pig-tail power connector 122 which is sent through HDMI cable 122 back to devices 108, 106, as shown in
