Abstract

A receiver allows controlling a device to be controlled such as a display device based on reference timing acquired from reception data without delay and with low power consumption, and includes: a communication device receiving data incoming intermittently; a first control circuit analyzing the data received by the communication device to identify the presence of a predetermined reference timing signal pattern in the data; and a timer for counting a clock from an initial value, generating a control signal for the device to be controlled according to a resulting count value, and if the count value reaches a predetermined interval value, resuming counting the clock at the initial value. The timer changes the initial value to reduce a count of the clock between the initial value and the interval value if the first control circuit identifies the predetermined reference timing signal pattern to be present.

First claim

What is claimed is:

1. A receiver comprising:
a communication device which receives data incoming intermittently;
a first control circuit which analyzes the data received by the communication device to identify whether or not a predetermined reference timing signal pattern is present in the data; and
a timer part which counts a clock from an initial value, generating a control signal for a device to be controlled according to a resulting count value, and if the count value rea…
