What's the deal with HDMI and CC? Two different systems (comcast & att U-verse) Two different TV's (LG & Samsung) neither one will display CC with HD in HDMI as the source. CC works ok with dvd / blue ray, works ok with tv when the source is set to tv and regular cable connection.
Any work arounds for CC & HDMI?
Thanks

Closed captioning is not part of the HDMI specification. The FCC really let the industry drop the ball on this one. The Comcast or Uverse boxes should (must?) have an option within their menus to display captions in their video output. Every OTA STB I've seen has closed captioning available generated by the box itself.

If worse comes to worse you may have to use a 480i video output like composite, or s-video. The cable boxes should preserve the CC information in the video and allow the TV to view it. Some poorly authored DVDs have the same problem. Closed captioning is only available, not subtitles. In order to view the captions the DVD player has to been in 480i and not in progressive scan mode or 480p.

Closed captions which are decoded and displayed by the TV, can be viewed from an external source (DVD player etc.) only via a 480i analog connection. This means composite video, S-video, or 480i component video (not 480p or higher resolutions). They cannot be viewed via HDMI, even if the resolution is set to 480i.

If the closed captions are decoded and made visible as part of the video image by an external source, then they can be displayed via an HDMI or high-resolution component video connection.

(Aha, eyager beat me to it...)

I have an SA HD STB with my Cox service which works on SD or HD channels on HDMI and Component connections. It is only a on/off/auto option in the STB which is disappointing. When I connect the cable directly to my set viewing the clear QAM SD or HD channels the set's CC works with all its options. The CC information is present on the cable but it does not pass through the STB. The STB must detect it and regenerate it.

This means composite video, S-video, or 480i component video (not 480p or higher resolutions). They cannot be viewed via HDMI, even if the resolution is set to 480i.

The HDMI committee was so obsessed with DRM that they completely forgot to include closed captions. Yet they travel just fine over S-Video. a 1970s technology that has much lower bandwidth.

If you have a cable box, there may be a hidden menu that controls digital closed captions.

Thanks all for the help.Found the cc in the menu of the AT&T box, the in-laws are now happy. :D
