.TH MUX 1 .SH NAME mux \- interactive television demo .SH SYNOPSIS .B mux/mux .SH DESCRIPTION .I Mux is a standalone application environment run from the Inferno console in .IR emu (1) or started automatically by .IR init (8) in a native environment. It directly uses the .IR draw (3) device and either keyboard or Infrared, and cannot be run under .IR wm (1). It is included in this release only as an example of the use of the Prefab graphics module described by .IR prefab-intro (2). The simpler style of graphics and interaction provided by Prefab and demonstrated by .I mux might be more appropriate than Tk on devices that use infrared remote control for interaction, such as televisions, or devices with limited screen space, such as pocket devices or portable telephones. .SS Configuration .I Mux produces a menu derived from the configuration file .BR /services/basic . Each line in the file has three fields, separated by .BR : , of the following form: .IP .IB icon : app : label .PP The .I icon is the name of a bitmap file to displayed in the menu alongside the textual .I label (which is the rest of the line). When the item is selected, as described below, .I mux runs the Dis file .IP .BI /dis/mux/ app .dis .SS Applications The following applications are available: .TF audioctl .TP .B fnn Financial reports: a scrolling `ticker tape' along the bottom of the screen. .TP .B movie Movies: select a film from a menu of categories .TP .B news Today's Newspaper: on-screen newspapers .TP .B tv Television .TP .B tvlist TV Timetable .TP .B pizza Order Pizza .TP .B email Internet mail .TP .B web Internet Web Browser: simplistic web browser .TP .B register Register with a service provider .TP .B ovid Presentations .TP .B audioctl Audio Control .PD .PP .SS Interaction .I Mux can be controlled using an infrared device, but for demonstration purposes under .IR emu (1) the infrared is emulated using the keyboard (see .IR ir (2)).
