CTA’s Canvass Committee has recently published ANSI/CTA-6003, Video Systems (525/60) - Video and Accompanied Data Using the Vertical Blanking Interval - Part 2: 525 Progressive Scan System IEC 61880-2: (2002-09). This standard represents the US National Adoption of IEC 61880-2: (2002-09), which specifies the aspect ratio code and the copy control information code and the method of transfer of these codes in the vertical blanking interval of the luminance signal. It is applicable to the transfer of video related information with the video signal through the baseband analogue signal of the 525-line/60-frame progressive scan video system. This standard is applicable to analogue video signal interfaces between digital and analogue video equipment as follows: 

• digital video equipment to digital video equipment;  
• digital video equipment to analogue video equipment;  
• analogue video equipment to digital video equipment;  
• analogue video equipment to analogue video equipment.
