ViewHD AV | Composite Video and L/R Audio to HDMI Converter "VHD-AV2HDMI" will merge and converter the input composite analog video and audio signals into single upscaled HDMI digital A/V signal at 720P or 1080P with integrated audio.
Attention: To use this item, the HDTV must support HDMI input at 720P or 1080P.
Operating Guide: Use the 720P/1080P switch button on the front panel to select the desired HDMI output video format. When the LED light is red, the output format is 720P; when the LED light is green, the output format is 1080P. The outgoing format will be rotated between NTSC and PAL as well, so the loop is (720P@60Hz to 1080P@60Hz to 720P@50Hz to 1080P@50Hz to 720P@60Hz...). For NTSC (60Hz) only TVs, there will be no picture or noise when the output format is at 50Hz(PAL). So please keep this in mind when using this item.
