CVBS (Composite Video)

Composite video is an analog video transmission and supported resolutions are 480i or 576i. ODROID-N2 supports this video feature and designed to connect with a TV through audio jack.

The CVBS video signal is assigned to the audio connector (CON6) and TV can be connected with a cable.

In order to select CVBS as a display output rather than HDMI, the Linux kernel command line must be configured properly and HDMI cable must not be attached. The CVBS picture format can be set in boot.ini.

# NTSC
setenv cvbsmode "480cvbs"
# PAL
#setenv cvbsmode "576cvbs"
 
setenv bootargs "${bootargs} cvbsmode=${cvbsmode} cvbscable=${cvbscable}"

For example, if the TV support 480CVBS picture format and its cable is connected, the Linux kernel command line would show like this.

$ cat /proc/cmdline 
console=ttyS0,115200n8 ... cvbsmode=480cvbs cvbscable=1 ...
