PureLink’s Breakthrough Fast-Switching Technology Conquers all Myths
RAMSEY, NJ – September 25, 2013 – A blink of a human eye takes 300 to 400 milliseconds. That’s one-third of a second. PureLink’s revolutionary PM Series matrix routers produce switching speeds that are virtually undetectable. That’s right – faster than you can blink.
The concept of switching multiple AV signals seems easy to understand. For users, it simply means inter-changing the images and sounds produced by each source from one display to another. However, what is overlooked by most, are the series of complex processes that must be precisely executed in order to produce a successful switch. This includes:
• EDID Handshake (exchange of display information)
• HDCP Handshake (validation of copyright legitimacy)
• Signal conversion (ex: digital signal to analog signal)
• Scaling (up-scaling or down converting of an input signal to correctly match the display, so that the best possible picture can be smoothly drawn onto the display)
• Audio Extraction/Insertion (insertion or extraction of audio signals from an input signal such as HDMI)
• Signal Conversion to optical or CatX for extension
• Sgnal Regeneration for error correction.
Correctly managing these processes alone to achieve reliable switching is an ongoing
challenge. However, making this step as fast as possible is an even greater challenge. There are many myths surrounding the performance factor of a matrix switcher.
Myth #1: The complex exchange of signals and information takes a little time.
The nature of the multiple processes and digital signals that must pass through during a switch makes it impossible to avoid a few blinks here and there, creating a lapse of at least a few seconds before the switch occurs.
Myth #2: HDCP handshake causes delays.
Another common reason is that HDCP handshake between multiple displays and sources takes time, thus resulting in a delay.
Myth #3: Older displays slow down the switch.
The switching time is also dependent on each display’s refresh capability. A display with a faster response time will produce a faster switch.
PureLink however, takes no excuses. The following short video clip demonstrates the switching capability of a PureLink PM Series matrix router, proving that these, in fact, are nothing more than myths. Take a look for yourself:
The conclusion? The performance of a matrix switch should not be judged by the success rate in switching, but by the speed of reliable switching that is produced each time. Don’t blink.. or you’ll miss the switch!
