Since the beginning of 2013, the biggest buzz in the A/V industry was and still is surrounding the future of 4K. To address the rapid oncoming of this new era of immersive visual experiences, manufacturers have developed and marketed not-so-ready 4K products and solutions as the only answers to 4K connectivity.

4K Distribution – The Good, the Bad, and the Distant Truth

Contributed by | PureLink


Typical HD video applications in markets such as medical, education, corporate IT, and broadcast, require managing multiple signals over long distances without losing signal integrity – a challenge that is magnified by 4K integration. While 4K video delivers stunning picture quality, the enormous bandwidth places extreme demands on the vast majority of existing HD infrastructures.

Even with a rise in 4K adoption, manufacturers have only just begun realizing that copper cable infrastructures do not provide enough bandwidth for full 4K HDMI distribution with full pixel density and color depth. Fiber, however, does.

In the Pro-AV World, There are Shortcuts to Success



Successful 4K video transmission, that is...

By only offering HDBaseT® 4K scaling and distribution, a leading control automation manufacturer's 4K certified switching solution fails to address multiple signal transmissions to remote locations over greater distances. 


For example, a university campus A/V system design requires multi-building connectivity with full 120x110 matrix switching of multiple SD, HD, and Ultra HD/4K video sources to multiple 1080p and 4K displays. 

System Requirements:

(Total: 120)

(Total: 110)

• 60 x 4K HDMI (less than 33 ft)

• 70 x 4K (over 330 ft)

• 36 x 4K HDMI (over 330 ft)

• 24 x 1080p (over 330 ft)

• 12 x 1080p HDMI (less than 33 ft)

• 16 x 1080p (less than 33 ft)

• 12 x SD Analog (less than 33 ft)


Technology Requirements:
