Beyond-IR: Remote Controls for Home Entertainment
It is amazing that we’re in the 21st century and reliant on a near 30-year old, one-way, line-of-sight-limited technology to control our bleeding edge consumer electronics products like our multi-thousand dollar plasma big-screen TVs and other entertainment systems.
The alternative to infrared remote control technologies is RF-based remote controls. RF-based remote controls overcome three major limitations of infrared technologies: line-of-sight and range; one-way communications; and high power consumption. Let’s take a look at each of these limitations and attempt to better understand why the primary interface to our home entertainment, the remote control, continues to be based on a 1980s era technology and how this will change, especially with the introduction of the RF4CE consortium and standards.
