Here's an idea I had when I was looking into failover/"emergency operation" for WITR's Rivendell setup.
Currently, we have a log called 'Emergency Log" that contains a Legal ID and a macro cart that loads today's log by running the date(1) command. Unfortunately (or by design) this loads a log and begins playback at the start of the log. At the end of the day it's not a huge deal because we have timed events built into our log that at 46 min past the hour sync up to the correct position in the log, but for those 45 minutes, stuff is playing out of order. Not that big of a deal at a music-centric community/college station like ours where there isn't a ton of underwriting/traffic slots that have to run at specific times, but it could be an issue if you're running a network feed at midnight or whatever. Would there be any way to piggyback on the 'scheduled' times of carts to implement an RML to load a log and "make next" or start at the current time? Usage cases: 1.) Rivendell box / file server at the studio site fails, and through a silence switch a backup box at the transmitter site is notified that there has been a loss of audio or digital clock. Through rdcatch or whatever means, a macro is triggered to start playback and switch the input to the processing/transmitter to a different source and begin playback of today's log or an emergency log. This log is started at the current time in playback 2.) "Master" rivendell box running RDCatch that somehow syncs up voice tracks/music tracks to "slave" boxes at network affiliates sees it's :59 past the hour (because all of our rivendell setups are synced over NTP.) The Master sends a message to slave nodes to start the "Network Feed In The Morning" 'log at a certain point based on what current time it is. I realize that there may be a way of doing this already that i'm not aware of, but I was just throwing this out there as an idea. -- *Chris Cmolik *|* RIT Information Technology '13* *Chief Engineer Emeritus, WITR Radio / Streaming Infrastructure Manager* [[email protected]]**
