Abstract
A codeset is described in a Public Codeset Communication Format (PCCF) as a format block including a plurality of fields having readily decipherable values, such as ASCII character values. One field is a mark/space information field that includes a sequence of mark time indicators and space time indicators for an operational signal of the codeset. A second field is a signal characteristic information field for the operational signal. Signal characteristic information may include carrier on/off information, repeat frame information, toggle control information, and last frame information. The PCCF is a codeset interchange format of general applicability.
Claims6
A controlling device, comprising:
- a microcontroller;
- a transmitting device;
- an input device;
- and
- a memory storing an encrypted codeset information;
- wherein the microcontroller further comprises both a decryptor that decrypts a command generating information that is caused to be retrieved from the encrypted codeset information in response to an input received via use of the input device and a rendering engine that uses the command generating information as decrypted by the decryptor to generate a command signal for transmission by the transmitting device to a controllable device and wherein the command signal generated by the rendering engine has both a format recognizable by the controllable device and a data indicative of a functional operation of the controllable device that corresponds to the input received via use of the input device.
