The VCR Plus feature was described. In the TV programming guide each program/show/movie had its own code. When user wanted to program the VCR to record a particular show she just had to enter the program code from the guide - no need to enter the start and end time. I was asked to design this feature. How can it be achieved?

Assuming that TV shows start and end at the 1 min interval (ie won't need to set the start to 1:35:28), there are 1440 mins in 24 hours. One solution would be to have an 8 digit VCR Plus code: xxxxyyyy The first 4 digits will be the start time, second 4 digits will be the end time. This will take 8 bytes of space.

Actually the VCR+ has 30 minute resolution. It packs the info into binary bits, then converts from binary to decimal, saving digits. The Java code is here: http://www.gginc.biz/java/vcr1.html
