Question and Answers
Answer:
You need to make sure the modulator is hooked up with HDMI and the CVBS as well. HDMI doesn't carry Line 21 data, that data actually has the CC. Without taking the CVBS from the DTV box and into the HDCOAX-8 you're only passing audio video to the modulator and not the CC. Once you hook up the CVBS ports from the STB to the modulator it will work right away.
 
The HDMI video doesn't carry separate CC, if you turn the CC on the STB, it will become part of the Video image which we will encode it, it will be always on the RF,
You can connect HDMI from the STB as a source of the Video and Audio and separate CVBS baseband video output for the same STB as a source of CC -closed captioning, our modulator will detect and read the CC information for the analog video CVBS signal encoded on line 21.
The modulator will generate a separate CC608  strem together with the MPEG video and audio strem, from this analog CVBS signal.
Now, you will be able to turn ON/OFF CC on this specific channel on the TV using the remote control
