[QUOTE="mm1352000, post: 1119771, member: 82144"] Possibly, yes. Whether the recording contains CC would depend on the CC format... because there is not just one format. For example, there is [URL='http://en.wikipedia.org/wiki/EIA-608']EIA-608[/URL] - an older standard where the CC data is transmitted in the analog video vertical blanking interval. I'm not 100% sure if this standard is applicable for digital broadcasts or not. Recordings may or may not contain this CC data. Then there is [URL='http://en.wikipedia.org/wiki/CEA-708']CEA/EIA-708[/URL] - the standard for "modern" digital ATSC over-the-air transmissions. The CC data is embedded in the video stream. Recordings should contain this CC data. There's also SCTE 27, which carries CC/subtitle data in a separate data sub-stream. I'm not sure how widely used this standard is, but recordings will [B]not[/B] contain this CC data. There are possibly other formats/standards too... Can you describe your TV source? In other words, do you receive clear QAM cable TV... or over-the-air ATSC TV... or something else? [/QUOTE]
