Abstract
A method for scheduling events between first and second video processing devices coupled together wherein each device having at least one event timer for storing a scheduled event. The method involves programming first event information into the first device, comparing the first event information to each event previously scheduled in the first device for determining conflicts therebetween, sending a message representing the first event information to the second device, comparing the first event information to each event previously scheduled in the second device for determining conflicts therebetween. A
user may be provided with information regarding conflicts and may be notified that a password is required for the first event and the respective event timer is enabled in response to receiving the password entered into the first device.
user may be provided with information regarding conflicts and may be notified that a password is required for the first event and the respective event timer is enabled in response to receiving the password entered into the first device.
