Star cluster codeset database for universal remote control devices

摘要

A codeset database for a universal remote control device includes a device index table, a key index table, protocol tables, and a set of keycode data structures. A keycode data structure includes a plurality of keycode data structure pointers (KDSPs) and one or more optional keycodes. In a star linking method, a keycode data structure is linked to multiple keycode data structures by pointing to those keycode data structures using multiple KDSPs. In a cluster linking method, a keycode data structure is linked to multiple keycode data structures by being pointed by those keycode data structures. A keycode data structure may not contain any actual keycodes, but a plurality of keycode data structure pointers and other information. A special value inside the keycode data structure is used to indicate whether and how keycode data structures are linked together.

1. A controlling device having a memory in which is stored a first device keycode data structure, the first device keycode data structure stored in the memory of the controlling device comprising:
a first keycode associated with a first key of the controlling device; a second device keycode data structure pointer pointing to a second device keycode data structure; and a third device keycode data structure pointer pointing to a third device keycode data structure; wherein the second device keycode data structure comprises a second keycode associated with a second key of the controlling device and the third device keycode data structure comprises a third keycode associated with a third key of the controlling device and wherein each of the first, second, and third keycodes comprise data used to generate an operational signal to be transmitted by the controlling device.
