Second part of the article on the application of the HDBaseT standard, which seeks to meet the specific needs of each use case.

One of the main advantages of HDBaseT is its flexibility, it can be used in a wide variety of use cases and applications. Not all situations require the same resolution, latency or transmission of the same type of data: some only need audio and video, others also require different types of controls, perhaps Ethernet and USB.

Before the creation of HDBaseT, installers limited themselves to what could be transmitted through a certain cable, which caused a proliferation of cables, restriction of the distances that could be covered and greater complexity. HDBaseT simplified things by allowing transmission over long distances (up to 100 m) of audio and video, Ethernet, USB, controls and power through a single Cat6 cable (or higher).

Depending on the specific needs of each client, the installers and integrators can choose the HDBaseT product with the necessary characteristics to meet the specific needs of each application.

Currently the HDBaseT Alliance has more than 200 members worldwide and there are thousands of HDBaseT products on the market, from simple extenders to projectors, switches / dies, screens, receivers and more. In the last article in this series, we analyzed some of the common HDBaseT applications and explained how technology can optimize digital signage and educational and business facilities. In the present article, we will examine other additional use cases.

In transport: connectivity in movement
Whether on long or short trips, passengers can always enjoy the projected content on bus or train screens. The possibility of seeing this type of material, be it purely informative, advertising or entertainment, improves the travel experience. To achieve this, public transport systems require a technology that makes possible a reliable and robust infrastructure for the transmission of high quality content in real time on several screens. HDBaseT offers maximum performance even in the demanding and challenging conditions of buses and trains.

HDBaseT is ideal for digital displays, public address systems, microphones, security cameras, stop button extensions, controls and power. Because HDBaseT allows point-to-point connection, daisy-chaining and multiple data flows, information, advertising and content can be cascaded simultaneously to numerous screens. Therefore, HDBaseT is ideal for connection in buses and wagons, but also for the infrastructure of the stations.

Another outstanding benefit of HDBaseT is the possibility of reducing the number of cables needed to transmit the different types of data, since installing more cables can be a challenge in these types of environments, particularly when reconditioning old vehicles. In addition, it is a very noisy environment, where several electronic systems compete for space and interfere with each other. HDBaseT is a technology of great robustness, capable of handling interferences without generating much interference itself. In addition, the HDBaseT protocol can compensate for any interference and transmission errors.

In the health sector: optimization of operating theaters
Technology in general has been integrated into many aspects of our lives, from the simplest cell phone to the most advanced systems in the world. One of the sectors where technology has saved lives is, by all accounts, the medical sector, which has provided equipment and systems that have optimized the way to diagnose and treat conditions.

Audiovisual systems are one of the main technologies implemented in the field of medicine, since they can facilitate medical procedures, optimize resources and maximize results. In addition, audiovisual resources can be used as useful training tools for students, who can see in real time what is happening in the operating rooms.

The surgeons have the possibility of operating with video images of the highest quality, which accurately and clearly reflect the procedures. While the advent of visualization systems for medical use can help improve the workflow of procedures, such systems create new requirements for advanced connectivity with high bandwidth to optimize video performance. For images to be useful in medical environments, reliable connectivity solutions must guarantee near-zero video latency, the highest image quality, simplicity and complete interoperability between multiple sources and screens.

During surgical and medical procedures, the agility with which decisions are made and techniques applied can be a decisive factor. To help maximize workflow efficiency, operating rooms need to use the most advanced digital platforms. The systems and monitors of images must be connected in an easy and agile way to allow an accurate and reliable visualization. This visualization is not only used to collect data for training, transmission and analysis, but also to allow surgeons to perform minimally invasive endoscopic procedures.

HDBaseT is an ideal solution for the health sector, due, specifically, to its ability to provide high quality images with almost zero latency. HDBaseT offers an advanced connectivity solution that meets the high standards of visualization technologies for medical purposes. In addition, thanks to the inherent interoperability of the HDBaseT technology system, different devices can be connected, allowing optimal video transmission, while processing different formats and types of input or output, such as 3G-SDI, DVI, HDMI and DP.

Although network cables of different categories are the simplest and easiest to use, many medical facilities require the exclusive installation of fiber optics. HDBaseT can also be transmitted through fiber cables at much wider distances, while still tunneling audio and video, Ethernet, controls and USB signals.

At home: no more clutter of cables
As our lives have become increasingly digital and connected, the number of devices, both sources and screens, has multiplied in our homes. The possibility of optimizing the audiovisual system in our homes can provide a better experience for customers.

With HDBaseT, there is no need to have several cables to connect our televisions to different sources: Blu-ray player, computers, game consoles, cable boxes, etc. Furthermore, there is no need to double the number of sources in our homes: the same Blu-ray player can transmit content to the living room, bedrooms and kitchen. In fact, with HDBaseT, all sources can be placed in a secluded location (for example, the basement or a closet) and then routed to different rooms with a single cable.

Another residential application of the HDBaseT is the home offices. In this context, the same requirements that we discussed in our previous article about installation in companies also apply here, namely, reliable, high-bandwidth and near-zero latency transmissions and interoperability between different devices. In this sense, all AV functions that a person enjoys in their usual office can find them in their home.

There is more…
HDBaseT is a versatile technology that can be used in different contexts, according to the specific demands of each installation. Other applications of HDBaseT include industrial PCs (embedded systems), the hotel and retail sector, houses of worship, government and military facilities, media, cultural and event centers, etc.

We would like to invite you to share your implementation stories with us, we will be happy to share them with all our members. If you want more information, you can contact You can do it in Spanish!

In our next article, we will explore the best practices for HDBaseT installations.
