Abstract
Computer readable media, methods and apparatuses may be configured for determining a rate of signal pulses transmitted by a device and a transmission interval occurring between a first of the signal pulses and a second of the signal pulses, detecting selection of a command by a user, and transmitting at least a portion of the command during the transmission interval.
Claims20
A method comprising:
- determining, by a remote control, a rate of signal pulses transmitted by a device and a transmission interval occurring between a first of the signal pulses and a second of the signal pulses;
- detecting, by the remote control, selection of a command by a user;
- and
- transmitting at least a portion of the command during the transmission interval.
1 more element
A method comprising:
- transmitting, by a display device, signal pulses at a pulse rate corresponding to a frame rate of a video program;
- transmitting, to a remote control, a message specifying the pulse rate and a time duration of a transmission interval between a pair of the signal pulses;
- and
- receiving, from the remote control, a command signal during the transmission interval.
1 more element
A method comprising:
- detecting, by a device, a command packet sent by a remote control;
- determining that the command packet comprises an end sentinel followed by an identifier data sequence that identifies an alternative signaling frequency and comprises remote control address data of the remote control;
- causing transmission of a pairing request comprising the remote control address data and device address data of the device;
- and
- receiving a pairing response message from the remote control to establish a communication session with the remote control using the alternative signaling frequency.
