Abstract
The disclosed method for reducing HRC mode reception time of CATV signals is intended for television receivers or video tape recorders provided with a CATV receiver suitable for the North American CATV system but not provided with a CATV mode (STD, HRC and IRC) selection switch. If a channel is selected, corresponding modulation frequency data is transmitted to a tuner. Subsequently, the video signal is checked for the presence of synchronizing signals, and this information is used to determine whether the broadcast is in STD mode or in HRC mode, prior to broadcast signal reception. This eliminates waiting time, reducing HRC mode reception time to only about 100 ms (the time needed to check for the presence of the synchronizing signals), and prevents noises from being generated as well as improving reception quality.
