New FCC rules mandating closed captioning of television content that’s streamed via IP take affect at the end of September.

Simon Hailes, CTO of Screen Systems, a company in the field of subtitles and closed captions, thinks the best approach to meeting the goal of providing closed captioning for the hearing impaired may be to ignore the standardization approach and insert text in the form of bitmap images over the top of video at the player.

Not only would the bitmap approach be more elegant, it also would make closed captioned content originating in the United States but viewed around the world more suitable to the needs of an international audience, he says.

In this podcast interview, recorded at IBC2012 in Amsterdam, Hailes lays out his thoughts on closed captioning of broadcast content destined to be streamed via the Internet.

Would like to have heard more about how this would actually work. Presumably the caption data is carried in the compressed media file. Then the viewer's player (usually in a browser) turns this data into bitmap graphics which are overlaid? Not quite sure how much that differs from current approaches, or how the graphics are created in the player.
