Shoutcast - radio controller
This script controls a shoutcast radio receiver and lets you select the stations that you configured on a notecard. Menu driven. Output of station description, genre and current song title using Xy text. Credits for this script go to previous developers of similar scripts:
- Scripter Coba who wrote the LandOwnersRadio (V2.0) script. Menu driven / notecard config script to select genre and station to set parcel music url.
- Jamie Otis who wrote the Raven radio infoboard script. Shows what song is playing by fetching info using the sis.slserver.info/sis.php service (now offline). Display on Xytext.
- Darkie Minotaur who wrote the currentPlaying script. Shows what song is currently playing by fetching info from the /7.html shoutcast page.
Although this script is based upon similar functionality as provided in these scripts, this script is not simply a merge/copy of those scripts, but a complete make-over. I use my own notecard format and processing of notecard info, and own menu system.

Current version: v0.3 released 10-2-2011
Scripts
Shoutcast - radio controller
This script should be put into the shoutcast - radio controller device.
// Script: Shoutcast - radio controller
// Version: 0.3 - released 10-2-2011
// Logic Scripts (Flennan Roffo)
// (c) 2010 - Flennan Roffo (Logic Scripts)
//
// This script is a remake of a couple of similar script:
// + LandOwnersRadio V2.0 by Scripter Coba (( menu driven / notecard config script to select the radio station and sets parcel music url ))
// + Raven radio infoboard by Jamie Otis (( worked at the basis of sis service [sis.slserver.com/sis.php] used Xy text display ))
// + currentPlaying by Darkie Minotaur (( used the /7.html info to fetch current song title info, displayed as float text ))
//
// Purpose:
// * Sets the parcel audio URL and displays the channel info
// * Uses Xytext to display the info.
// * Fetches song title info from the shoutcast url
///////////////////////////////////////////////////////////////////////////////////////
// Extra Features -- 0.1 release
// * On/Off option
// * Allows multiple menus (if options per menu > 12) using a prev/next button
// * Checks if your url is well-formatted
// * Will delete genres for which no stations exist
// * Will skip stations that have same url and same genre (you can however have an identical station url under different genres).
// * New notecard format
//////////////////////////////////////////////////////////////////////////////////////////
// Extra Features -- 0.2 release
// * Configurable button text
// * Gets parcel URL and automatically sets the genre/station and on/off status accordingly (<-- doesn't work)
//////////////////////////////////////////////////////////////////////////////////////////
// Update -- 0.3 release
// * Fixed bug (only first station in genre displayed in menu)
// * Auto reset script when config card updated
// Notes:
// * Expects url to be in the format: <ip>:<port>, where <ip> has the format: xxx.xxx.xxx.xxx (0 <= xxx <= 255)
// * Deletes entries in category (genre) for which no stations are configured with notice.
// * Skips stations which have identical url AND same category (genre).
//////////////////////////////////////////////////////////////////////////////////////////
// Upcoming release -- 0.4
// * Will add functions for remote controller(s) and remote display(s) using llRegionSay to communicate over a channel.
// * Should relax on the constraints about the input format of URL's (currently requires that URL has format: xxx.xxx.xxx.xxx/yyyy).
// * Fix button placement. Control buttons should be on the first line.
// * Implement script reset on change of owner.
// * Permit station to be put under multiple genres, using a comma-seperated list of genres in the section [STATION]
// (currently this is only possible by duplicating the entire line and change the genre.)
/////////////////////////////////////////////////////////////////////////////////////////
// Future plans:
// * Individual user preferences that can be stored on seperate note cards. A user has access to his own list of genres and stations and the system available genres/stations.
// * Feature for accessing online playlists (M3U, PLS, other formats) to play a list of songs provided by that playlist.
// * User provided url.

Notecard format
Example notecard

TODO
Planned for upcoming release 0.4:
- Add a llRegionSay to broadcast the <station>|<genre>|<current songtitle>|<url> to the region and add a script that displays that info on a remote Xytext board. (for use with a remote controller and/or remote display board anywhere in the region/parcel)
- llResetScript on owner change
- Relax on URL format
- Allow multiple genres per station
