This document describes some enhancements to the INPUT SIGNAL MODE command and OUTPUT SIGNAL MODE commands of the AV/C Tape Recorder/Player Subunit Specification, Version 2.1. The effect is to add a NOTIFY status to these commands so that a controller of the Tape Recorder/Player

Subunit can be notified when there is a change in the status of these two modes.

This document should be read in conjunction with the AV/C Tape Recorder/Player Subunit Specification, Version 2.1, Ref [1]
