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.
Claims7
A method performed by a controlling device having an input element, comprising:
- responding to an activation of the input element by using, in combination, a first command generating information that is retrieved from an encrypted codeset information stored in a memory of the controlling device and decrypted by a decryptor of the controlling device and a second command generating information that is retrieved from an unencrypted codeset information that is stored in the memory of the controlling device to generate a command signal for transmission by a transmitting device of the controlling device;
- wherein the generated command signal will have both a format recognizable by a controllable device and a data indicative of a functional operation of the controllable device.
