Subject: [stella] CC Standard From: Glenn Saunders <krishna@xxxxxxxxxxxx> Date: Sun, 3 Aug 1997 17:37:10 -0700 (PDT) |
I found just about everything BUT the CD standard, known as EIA-608. Unfortunately there is a $106-110 extortion fee necessary to receive a copy of the technical standard. I suspect that a copy of this document may be available on the internet but I simply can not find it via normal searches on Yahoo, Magellan, or Excite. There is a book available for $30 which should include this document. I would have a lot of respect for the individual dedicated enough to go to such lengths to figure this out. Of course, you could try reverse-engineering it. More on that later. Here is the book: Inside Captioning Order a copy * (or copies!)

The data is encoded in Line 21, field 1. This field is split up into two portions, for two separate channels. Field 2 is now in use as a 2nd language thing. I suppose that despite the 2600's dual-field "noninterlaced" nature that CC decoders should be able to handle the signal okay, that is, as long as the placement of the 2600 playfield pixels lines up with the expected placement of the white-on-black slivers of standard CC data. ------------------- PLACEMENT: Currently, four rows at the top and four rows at the bottom of the picture are available for caption display. Additionally, there are eight indents to allow left-to-right placement of captions. Full 15 row by 32 column screen addressing has been specified by the FCC for decoders mandated by the TV Decoder Circuitry Act. This expanded specification can be used compatibly with TeleCaption II and later decoders, but it is incompatible with the original TeleCaption (TeleCaption I) adapter. Italics and underline: As in printed text, upper- and lower-case italics and underlining may be used to indicate emphasis. You may use standard print methods of setting off the text of a speaker who is not physically present in a scene, such as a narrator, the voice in a dream, a flashback, or the voiceover reading of a letter. For example, these may be rendered in italics. (In documentaries, however, a frequently heard voice such as the narrator's is usually in roman.) COLOR: Do all TVs support color captions? The FCC strongly encourages, but does not require, manufacturers to include color capability in their televisions. Most television manufacturers are including the capability now, and this trend is expected to continue. STYLES: What character formatting attributes are available? With the latest decoders, caption text can be displayed as white or colored characters on a black background. They can be normal text, italicized, underlined, flashing, or any combination of those attributes. CHARACTER SET: The Caption FAQ Line 21 Captioning Character Set Back to top Feedback Sponsored by Cheetah Systems By Gary D. Robson Updated: February 1997 _________________________________________________________________ This is the character set called out by the FCC, effective July 15, 1991. For the most part, it follows standard ASCII. Exceptions are marked with a * in the "Symbol" column. The set of two-byte codes at the end of the table require that the first byte be (hex 11) if the character is being sent to channel 1, or (19 hex) if the character is being sent to channel 2. Note that the registered trademark symbol (hex 11,30) and trademark symbol (hex 11,34) were changed when this standard was enacted. On decoders manufactured prior to the effective date of this standard (hex 11,30) was a ¼ (one-fourth) symbol, and (hex 11,34) was a ¾ (three-fourths) symbol. Additional note: not all web browsers and operating systems can display all of the characters in this table, which is why the "Description" column was added. The solid block (hex 7f) and the music note (hex 11,37) can't be displayed by any browser (that I know of), so the symbols aren't in this table at all.
