Several telecommunication programs offer audio broadcast
capability. It has been the MMC's experience that while the human
eye is tolerant of dropouts and data loss in visible images, the human ear
is much more sensitive to data loss. Almost all audio broadcast
programs experience data loss. For that reason, the MMC continues to
utilize telephones for audio communication. However, information on
the telecommunication programs offering audio broadcast is presented.
The differentiating factor between telecommunication
programs offering video broadcast is image size and network bandwidth
utilized, which are necessarily related by the compression algorithm used
by the broadcast. It has been MMC's experience that while image size
of 120 X 160 pixels can be utilized, image size of 320 X 240 or even 640 X
480 pixels are desirable.

Electronic notebooks are still in their infancy stage.
Functionality, user interfaces, and robustness are the discriminating
factors. Most electronic notebooks are custom written software.
Remote tours are a methodology for familiarizing a
user with facilities before their visit. These tours provide an
image of the facility, narrative about the facility, and navigation
around the facility. This allows the user to become familiar with the
facility layout and instruments prior to arriving on-site.
Web based control of instruments is the most challenging and difficult
aspect of the MMC project. While there are one or two commercial
instrument control programs, most are still custom software.
