Must be different IR hardware
And some! Seems the underlying technology has changed recently to enable low cost, low power, high range units to be embedded into phones / pda's.
Agilent, who supply the software with the samsung, also design and make the hardware.http://news.thomasne...tory/461929/264
"Agilent Technologies Introduces Industry’s Smallest, Lowest-Power Infrared Transceiver for Universal Remote Control via Mobile Phone
Transceiver’s 1.6mm Ultra-Low-Profile Package and 1.8-V Logic Input/Output Interface Enable Slimmer, Compact Mobile Devices
PALO ALTO, Calif., March 14, 2005 -- Agilent Technologies Inc. (NYSE: A) today introduced the industry’s smallest, lowest-power infrared (IR) transceiver that enables mobile phones and personal digital assistants (PDAs) to function as universal IR remote controls for televisions, VCRs, DVDs and other home appliances. The new transceiver offers a remote control distance of up to 7 meters (approximately 23 feet) with an IrDA (Infrared Data Association) link distance of up to 50 cm (approximately 20 inches) and compatibility with Agilent’s universal remote control software."
Speed is upto 4 mb/s so fairly reasonable, IRDA certified link range is 50cm so laptop links should be better. Maybe IrDA has a new lease of life? an off-the-peg solution from one manufacturer of componants for approx $2USD in 'moderate volume' - how long before it spreads to other devices? From reading their product spec the actual control software can also be embedded within the emitter so that 'dumber' devices can also play too
But these cost $4...http://www.avagotech...licationId=5267
Come on HTC, catch up!
