Hmmm I am not an expert on things like this but I think it has something to do with DVD
I found this link (IN FRENCH)
It has screenshots that are near-enough exact to the one shown above
I fdid however translate this about one of these things
Babel Fish Translation, In English:
"- drive Video ESS: ES4318 F U260 (TTS1505Å) It is the processor a principal... processor MIPS which is used esentiellement to readers DVD and Set signal bow for the tele interactive one... This is the hand processor (one uses the very early scan models, now replaced with ADV7172 processor TV encodeing).... MIPS processor that is specially designed for DVD players and Set-Signal boxings for interactive TV "
Hope this helps
