What is HDBaseT and Why Do I Need It for My Projector?



The wonderful world of technology brings a revolution to the fore every few years that captivates attention across the globe while significantly boosting performance. Regardless of the technological advances, one of the biggest issues faced by consumers across the globe is cable management. Even though wireless data transmission has improved by leaps and bounds, it still cannot match the efficiency and low latency of a cable. Latency issues and lag arecommon while transmitting 4K video and audio simultaneously, which is unpleasant.


On the other hand, using multiple wires leads to a clutter of cables that is hard to manage. It is true for devices like LCDs and projectors that require multiple cable connections that include power, HDMI, and Ethernet at the very least.


It is a common sight inside rooms where the projector or the display is installed at a distance from the input device, a general scenario in boardrooms, offices, restaurant outlets, and even homes. Consider three cables, each 50 feet long and try to find space to hide them from plain sight!


But no more clutters! With the revolutionary HDBaseT technology.


What is HDBaseT?


HDBaseT is the answer to the prayers of all the people who wished for easier cable management. It is an indigenous standard developed for data transmission. It is promoted by the HDBaseT Alliance, a group of companies whose members include LG, Samsung, and Sony. It is based on a patented technology called 5Play which facilitates transmission of multiple signals over a single cable.


A solitary HDBaseT cable can transmit:


- 2K/4K UHD Audio & Video Signal in an uncompressed format.

- Ethernet Signal at 100Mbps (100BaseT)

- Power up to 100 watts for running the device.

- Serial Communication Data Control Signals including CEC, IR, IP, and RS – 232.

- USB2.0 for Touchscreens and Kernel Virtual Machines

A CAT 5e or CAT 6 Ethernet cable is used for transmitting all these signals and can send data up to distances of 100 meters easily, which is a little over 300 feet.


HDBaseT Projectors


Many commercial devices can benefit from the HDBaseT standard, but projectors and displays are the ones that will gain maximum advantage. The reasons behind this are that firstly projectors are installed at quite a distance from the input source and secondly, they require multiple cable connections. Quite a few manufacturers of projectors have been creating HDBaseT compatible projectors which also support concurrent technologies.


JMGO just launched a laser projector which runs Android OS and can project a 150''(3.8m width) image with the projector just 34 inches (88cm) away from the wall.


The HDBaseT Advantage


HDBaseT has numerous advantages when compared to large-scale multi cable transmission setup.


Cost Effective: For long distance installations, HDBaseT reduces the initial investment in infrastructure as fewer cables are required.

Economically Viable: The hardware infrastructure required is cheap but doesn’t compromise on the quality.

Clutter Free: It makes cables management easier and creates a clutter-free and minimalistic environment.

Easier Installation: The installation process faster thanks to this futuristic technology and requires minimal modification to the establishment’s structure.

Flexible Installation Options:HDBaseT eliminates the need to have a power outlet close to the device allowing for flexible installation.

Lasts Longer: A HDBaseT cable is sturdy and lasts longer than conventional cables.

Lossless Transmission: The video and audio signals are transmitted in an uncompressed format, ensuring better quality.

Predefine Standard: HDBaseTspecifications are predefined and globally accepted and cause no interoperability issues.


Who to buy HDBaseT projectors


HDBaseT Projectors will not make sense for the average consumers who want to connect their devices at a distance of a couple of meters. The technology is beneficial in scenarios where data transmission over long distances is required. These include organizations with large premises having multiple buildings on their campus.


When to Purchase A New HDBaseT Projectors


HDBaseT is an ideal investment for multiple organizations that are setting up new infrastructure or offices. 


Commercial Outlets: HDBaseT is a boon for commercial outlets that make use of projectors and audio systems such as sports bars, restaurants, pubs, discotheques, and clubs. These outlets typically have multiple cables running across the establishment over long distance and switching to HDBaseT will make sense for them.

Corporate Offices: Corporate offices that have multiple boardrooms and are dependent on projectors will find HDBaseT projectors as a great investment. The bigger the office, the better the returns on the technology.

Colleges, Schools, and Educational Institutions: Educational Institutions that have buildings and departments spread across their campus may opt for HDBaseT projectors.

Other Large-Scale Organizations: Other large-scale organizations including hospitals, industries, and hotels that will require transmission of the supported signals over long distances may buy HDBaseT projectors.


When to Upgrade Existing Projectors to HDBaseT


Organizations that already have HDBaseT compatible projectors and use multiple cables for data transmission may switch to HDBaseT under following scenarios.


Premises Upgrading to 2K/4K Ultra High Definition Platform: Premises that use projectors and are planning to upgrade the video and audio from 720p/1080p to 2K/4K may switch their projector cables to HDBaseT for better quality transmission.

Establishments Facing Cable Management Issues: Owners of establishments that face extensive cable management issues and are tired of the hassles may opt for HDBaseT projectors or cables if it is cost efficient for them.
