NAME
mux - interactive television demo
SYNOPSIS
mux/mux
DESCRIPTION
Mux is a standalone application environment run from the
Inferno console in emu(1) or started automatically by
init(8) in a native environment. It directly uses the
draw(3) device and either keyboard or Infrared, and cannot
be run under wm(1). It is included in this release only as
an example of the use of the Prefab graphics module
described by prefab-intro(2). The simpler style of graphics
and interaction provided by Prefab and demonstrated by mux
might be more appropriate than Tk on devices that use
infrared remote control for interaction, such as televi-
sions, or devices with limited screen space, such as pocket
devices or portable telephones.
Configuration
Mux produces a menu derived from the configuration file
/services/basic. Each line in the file has three fields,
separated by :, of the following form:
icon:app:label
The icon is the name of a bitmap file to displayed in the
menu alongside the textual label (which is the rest of the
line). When the item is selected, as described below, mux
runs the Dis file
/dis/mux/app.dis
Applications
The following applications are available:
fnn Financial reports: a scrolling `ticker tape' along
the bottom of the screen.
movie Movies: select a film from a menu of categories
news Today's Newspaper: on-screen newspapers
tv Television
tvlist TV Timetable

web Internet Web Browser: simplistic web browser
