[1] All JP1 remotes are made by Universal Electronics, Inc.[2] UEI sells various models under their One For All brand name,[3] and supplies remotes to consumer electronic manufacturers such as Radio Shack, Sony, and Sky, as well as North American cable TV providers such as Comcast, Rogers, Cox, Shaw, Charter and Time Warner.
Updates and extensions include new device code data, new IR protocols, advanced keymapping, and macros.
[7] Nicola Salmoria discovered how to add new functions by writing software "Extenders" (protocols which replace a JP1 remote's main processing loop).
In October, 2000, at remotecentral.com’s "General Consumer Remotes" forum, electronics hobbyists Dan "HW Hackr" Nelson and Rob Crowe[8] worked out how a JP1 connector could be used to examine and modify that portion of a remote control's memory containing user configuration data and user-updated devices.
The JP1 Remotes Forum expanded on that work, and remains the foremost locus of discovery for exploiting new JP1 functionality.
This control can operate up to four consumer devices, with protocols and code sets normally limited to TV, analogue satellite and VCR.
Remote controls in this product range can normally be identified by the presence of three programming eyelets in the battery compartment.
