Harmony 670, a universal remote. A universal remote is a remote control that can be programmed to operate various brands of one or more types of consumer electronics devices. . Low-end universal remotes can only control a set number of devices determined by their manufacturer, while mid- and high-end universal remotes allow the user to program in new control codes to the re
The article has that Philips Magnavox made the first universal remote (and indicates they may have), but Steve Wozniak in his book iWoz, 2006, claims that he was "the first to make what is now known as a universal remote control" (p262).
Most of these were connected to the set being controlled by wires, but the Philco Mystery Control (1939) was a battery-operated low-frequency radio transmitter, [14] thus making it the first wireless remote control for a consumer electronics device. Using pulse-count modulation, this also was the first digital wireless remote control.
Universal Remote Console (URC) is a standard for defining alternative user interfaces for devices that can be used remotely. In the vocabulary of URC, the remote devices are called "controllers", while the devices they control are called "targets".
The term "Commercial Wireless" had a different meaning in the early days of radio and telephone. Magnavox manufactured radios, TVs, and phonographs. In the 1960s, Magnavox manufactured the first plasma displays for the military and for computer applications. Magnavox Odyssey. In 1972 Magnavox introduced the Odyssey, the first video game console ...
Function codes may specify a unit number code (1–16) or a command code. The unit number or command code occupies the first 4 of the 5 bits. The final bit is a 0 for a unit code and a 1 for a command code. Multiple unit codes may be transmitted in sequence before a command code is finally sent. The command will be applied to all unit codes sent.
Simple remote control systems use a fixed code word; the code word that opens the gate today will also open the gate tomorrow. An attacker with an appropriate receiver could discover the code word and use it to gain access sometime later. More sophisticated remote control systems use a rolling code (or hopping code) that changes for every use.
A JP1 Remote Control. A JP1 remote is a type of universal remote, usually with a six-pin interface connector labeled "JP1" in the battery compartment, manufactured by Universal Electronics Inc. The JP1 interface allows the remote to be reprogrammed, adding new code lists and functions. Home theater hobbyists use JP1 to avoid obsolescence.
