I have simple, if expensive, needs. I want to achieve, in 2018, the kind of immersive glow that the Philips Ambilight, a product last updated in 2007, provided the TV obsessive a decade ago. I can drop $US150 ($192) on the Dreamscreen backlight, but I'd much rather use the eight Philips Hue lights already in my basement. If TV and set-top box makers embrace Philips's new Entertainment API, my needs might finally be met.
