Overview

Sync Generator with Reference In
The ADVC G4 is more than just a compact and robust sync generator.
While most competitive products have only six outputs and restrictions on SD and HD signals, the ADVC G4 has nine outputs that can be individually controlled in groups of three.
For example, three outputs can be SD, the other six can be HD, or vice versa.
The ADVC G4 also includes a 48 kHz wordclock as well as a reference input, which allows it to be used as an extender when more than nine outputs are needed, or when an extension from the main system is necessary.
The ADVC G4 features the highest signal quality, best functionality, and the most comprehensive format support in the compact sync generator market.

Videoguys Notes
4) Grass Valley ADVC-G Series Converters
The ADVC line of converters have been the industry standard for HDV/ DV/Analog converters going back to the days of Canopus. Grass Valley purchased Canopus several years ago and with the introduction of the G-Series the ADVC line-up has grown up to fill the needs of broadcast professionals and post houses that require SDI connectivity and conversion.
What I like best about the G-Series of converters is the combination of quality and rugged reliability, at affordable prices. When you get one of these babies in your hands, you can immediately tell from the look and feel that they are up to the task in even the most torturous professional environments. This is not to put down other lines of converters, I just really like the rugged design the Grass Valley team came up with. 
- The ADVC-G1 at $1,199 converts your analog, HDMI and DVI signals to HD/SD-SDI. It also upconverts SD footage to HD which makes it perfect for editors with older legacy gear trying to integrate it into an HD workflow via SDI.
- The ADVC-G2 at $999 converts your HDMI and SDI signal to analog. Converts HDMI to SDI. Also downconverts your HD footage to SD making is a great choice for anyone looking to pull HD content into an older analog or SD workflow.
- The ADVC-G3 at $999 converts SDI input into HDMI output. Combines dual SDI input into a single HDMI output. Editors working with 3D footage can use the ADVC-G3 to combine both inputs into a multiplexed 3D HDMI output.
- The ADVC-G4 at $699 generates Sync for multiple devices using a single input. This is for those who need to sync multiple SD and HD signals for use in broadcast production environments.
