Operational states include, inter alia, tuner frequency: transport mode such as recording, playing or stopped: and current position within the recording media, for example a timecode, elapsed time or time remaining. The commands can also include commands to interrogate the memory within the video recorder. information may thereby be discovered remotely, for example the time, date, channel and duration values corresponding to events that have been set for unattended recording. Further the commands include commands to control the positioning of the recording and reproducing heads of the video recorder; commands to place the recording means of the video recorder into a recording condition, a replaying condition, a forward advancing condition, a reverse advancing condition, a position seeking condition, a pause condition or a stop condition and commands to tune the tuner to a particular frequency or channel.</p> |
