Abstract

An improved universal remote control unit (URC) for controlling electronic appliance units. The URC unit has the typical remote controller module for controlling appliances such as TV, stereo, VCR or DVD. Additionally, the URC has a scratch pad memory for storing telephone numbers and web site information entered through the URC unit'"'"'s alphanumeric keys. When activated, the key pad entries are stored in the memory, instead of being used to control the appliance. The URC unit further has a digital recorder module that can be implemented with a microphone, a voice recorder chip and a speaker, all integrated with the URC unit. The digital recorder module can even use the battery that is typically used by the URC unit. The URC unit further has a display screen to display the information stored in and recalled from the memory.

memory control to selectively fast-forward, reverse, erase, playback, make permanent at least one of the plurality of the signals stored by the FIFO memory.

7. The URC according to claim 1, wherein the digital voice recorder comprises:

a microphone to receive the audio signal concurrently generated by both the user and the user'"'"'s ambience, said microphone being operationally independent of said control circuitry'"'"'s controlling of said appliance;

a memory to store the received audio signal directly from said microphone;

a speaker to play back the received audio signal stored in the EEPROM, and

control circuitry to operate the digital voice recorder upon the user'"'"'s command, wherein said control circuitry is operationally independent of said microphone, memory and speaker.

8. A universal remote control (“

URC”

) to control at least one electronic appliance, comprising;

a portable housing (40);

a plurality of keys (405) located on a top surface of said portable housing, comprising a set of numerical keys corresponding to the numerals “

0”

through “

9”

, superimposed by alphabets from letter “

A”

through “

Z”

;

a first control circuit (418) which, responsive to inputting from said keys, remotely controls the operation of the at least one electronic appliance, the first control circuit being located within the housing;

a memory (420) which controllably stores the keys entered by the user, independent of the operation of said first control circuit;

an LCD display (450) located on the top surface of the housing to display the keys stored in said memory;
