AirSpeed Multi Stream Database Overview
The term “database” as used in AirSpeed Multi Stream refers to an actual database as well as
all of the associated image and clip files that are associated with that database. Therefore, the
term database can refer either to the actual database file itself, or the database file plus all of
the associated files.
The files in a database are as follows:
• The database itself. These files are located at the root of the database structure and are
named as follows:
- t_flash_st.db
- t_flash_st.idx
- flashtkn.tku
- flash_st.lok
• The Essence files. These contain the actual video and audio essence. They have a suffix
of .tmf and are in the “clips” subdirectory.
• The head frame files. These contain a full resolution uncompressed YUV still image of
the selected headframe. They also contain a redudant copy of the metadata for the clip.
They have a suffix of .g and are located in the “pic_dir” subdirectory.
• The icon files. These contain low resolution YUV still images in several sizes and are
used by the GUI to draw the images on the VGA screen. They have a suffix of .D and
are located in the “bw_pics” subdirectory.
• The proxy files. These contain low resolution video and audio. They have a suffix of
.mpg and .mpg.index, and are located in the “proxies” directory.
