Sony called their portable CD-i players
Intelligent Discman. There were two models with an LCD display, the
IVO-V10 and IVO-V11 (see picture). The IVO-V11 was an improved version
of the IVO-V10, it solved some compatibility issues and it was
compatible with the standard for CD-i pointing devices. Besides these
models, there was also a Sony CD-i portable without an LCD screen. The
players could not be upgraded with Digital Video functionality. They
were intented for professional usage.
DVS, a small multimedia company from the
US, produces its own CD-i player for professional applications: the
Video Engine 200 (see picture). As from the end of 2000, this unit is
still on sale.
