Method and apparatus for remote control transmission
First Claim
1. A remote control comprising:
- a first circuit operative to generate a transmission comprising first and second portions, said first portion of a duration within a first time range, and said second portion of a duration within a second time range, and to generate a signal indicative of an end of transmission of said first and second portions; and
timer circuitry in communication with said first circuit and operative to render said first circuit signal indicative of an end of transmission inactive when a time length of the first and second portions exceed a predetermined time, and to generate a replacement signal for said first circuit signal indicative of an end of transmission after expiration of the time length of said second portion.

Abstract
A remote control is operative to transmit a remote control signal composed of a first portion and a second portion. The first and second portions are typically a pulse and a space. The pulse has a pulse width of a given duration within a pulse width range, while the space has a space width of a given duration within a space width range. An interrupt signal provided to indicate the end of transmission of the remote control signal is disabled when a space portion requires a space width greater than the space width range. The interrupt signal signaling the end of the remote control transmission is then disabled for a predetermined period of time essentially equivalent to a length of time that the additional space exceeds the space width. During the predetermined period of time, the remote control thus a space. The interrupt signal is then re-enabled after expiration of the predetermined period of time in order to allow for another remote control transmission.

9. A method of generating a remote control transmission comprising the steps of:
-
generating a remote control transmission comprising first and second portions, the first portion of a duration that is within a first time range, and the second portion of a duration that is within a second time range;
generating a signal indicative of an end of transmission of the first and second portions;
inactivating the signal indicative of an end of transmission when a time length of a second portion exceeds a predetermined time; and
generating a replacement signal for the signal indicative of an end of transmission after expiration of the time length of the second portion. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. In a remote control having an integrated circuit operative to generate a remote control transmission comprising a pulse and space, the pulse having a pulse width within a pulse width range, and the space having a space width within a space width range, the integrated circuit further operative to generate a signal indicative of an end of transmission, a method of extending the transmission beyond the space width range comprising the steps of:
-
providing an interrupt signal to the integrated circuit after transmitting the remote control transmission, the interrupt signal operative to temporarily disable generation of another remote control transmission;
providing a timing interval equal to an amount of time that said space is to exceed the space width range, the timing interval equivalent to a space; and
enabling generation of another remote control transmission after expiration of the timing interval.
