image usage information from a TV manufacturer

There are two ways using image in TTML in Japan.

One is using SVG image format to define another Kanji that is not
defined ARIB STD-B62. In fact, there are many Kanji that is not
in the standard Japanese fontset, expressing persons name and/or
locations. Also some TV programs in Japan, Broadcaster uses emoji character
using SVG.

Another usecase of image, the broadcasters can transmit
PNG image on TTML, this TTML is not for captioning the programs,
but for alerting with messages.  We call it "superimpose".
For example, if there is an earthquake and tsunami coming up to,
broadcaster send warning message in TTML format.
In this case, they might add a map where will be serious.
