Your best be there is to order a SMPTE CD which has all of the latest specs. If you're looking at subtitling, then that a whole different ball of wax. Hello, May I ask if any documentation on Spruce STL is available? I would like to know this : ----------- ------------- Thank you. -- 子曰 不而不改 是謂過矣니라 공자께서 말씀하시길, 잘못을 하고도 고치지 않는 것, 그것을 잘못이라 한다. - 論語< 衛 靈 公>편 JongAm Park jongampark@sbcglobal.net Visit my personal blog at http://jongampark.blogspot.com Visit my technical blog at http://jongampark.wordpress.com _______________________________________________ Do not post admin requests to the list.

I think you're confusing closed captioning with subtitling. STL is a subtitle format, there is no mapping to closed captioning. Each file is a 4 bit TIFF file, uncompressed. It is a rendered image of the subtitle itself. The RGB map, which is fixed palette, states which color to map to each TIFF palette index. 608 is pretty straight forward with command byte pairs to indicate CC channel and what type of display you would like (roll-up, pop-on, paint-on, etc). As for 708, you're dealing with new terror-tory! You're looking at, in the most generic implementation, generating CDP packets with mandated 608 codes as well as native 708 codes.

There’s a million possibilities, and I had hoped someone wrote a few of them down ;) However, it would be very nice if there is a full document or any document.
