CHAPTER 1. GENERAL DESCRIPTION OF PRODUCT
1-74
7-10 Support for Analog Signal I/O Copyright Protection Signals
(1) Detection of copyright protection signals added to input signals
• Detected copyright protection signals: Pseudo-synch pulses and CGMSA (Copy Generation Management System for analog)
signals
• Signal detection time: 20 seconds maximum
(2) Copyright protection signals added to output signals
• Macrovision (pseudo-synch pulses): Not added

7-11 Video ID1 Detection/Output Support
(1) S1 signal output
When a Full mode (squeezed) video signal, consisting of 16:9 video compressed to 4:3, is output from the S terminal, an S 1 -
compatible wide monitor will detect an identification signal for automatically restoring the 16:9 video (e.g., during playback of a
tape recorded in Camera 16:9 mode or a tape containing system data related to the aspect ratio).
• NTSC
→
16:9 Full mode + 4:3 Letter Box mode identification signal output
• PAL
→
16:9 Full mode identification signal output
(2) Video ID1 output
• When a Full mode (squeezed) video signal, consisting of 16:9 video compressed to 4:3, is output from the composite video
terminal or S terminal, a video ID 1 /-compatible wide monitor will detect an identification signal for automatically restoring the
16:9 video (e.g., during playback of a tape recorded in Camera 16:9 mode or a tape containing system data related to the aspect
ratio).
(3) Detection of S1 signal or video ID1 during line input (ID1 is for NTSC models only)
• A video ID 1 /S 1 signal multiplexed onto a video signal input from the composite video terminal or S terminal is detected, and
system data relating to aspect ratio information is recorded.
(4) Detection of WSS (Wide Screen Signaling) signal during line input (iPAL model only)
