Section 4.0 Choosing the Correct Automation Tool

Rivendell includes two modules specially optimized for performing automatic operations:

The RDCatch and RDAirPlay modules. The two modules take radically different

approaches in how they go about organizing and controlling operations, so a few words

regarding each may be in order here.

RDCatch is aimed at executing actions on the basis of a strict time-based schedule,

referred to as an event list. Each action (which can be a recording, a play out, an up- or

download, a macro execution or an operation on an audio switcher device) executes on

the basis of its scheduled time in the event list, independently of all other actions. As

such, RDCatch is often best suited for use in settings such as network head end

operations or 'auxiliary' roles at broadcast stations, where the transitions between events

are generally not an important part of the presentation.

RDAirPlay takes a very different approach, in that most events are organized into one or

more playlists or logs. A Rivendell log is a list of one or more carts, organized in

chronological order. As the name implies, RDAirPlay is optimized for use in situations

where the transitions between the various program elements are a key part of the delivery

and presentation of the content, such as in live air play environments.

Of course, it's entirely possible to use both modules, even together on the same machine

at the same time – the Linux OS makes for a very robust and capable multitasking

system.

Section 4.1 The RDCatch Main Window

After starting up RDCatch, you should see the main RDCatch window, looking

something like Illustration 11. The window consists of four areas: the record / play out

decks at the top, the filter areas just below the decks, the events list and the audition

buttons and other buttons at the bottom. We'll cover each of these in turn.

4.1.0 The Record / Play Out Deck Area

If the system administrator has configured one or more RDCatch record or play out

decks, they will be visible at the top of the RDCatch main window. A record deck is a

virtual 'recorder' that can be used to make automated recordings, while a play out deck

can be used to automatically play out audio. It does not matter on which particular host

a particular deck 'resides' – all Rivendell decks throughout the system are visible in

RDCatch, regardless of which host it is run upon.

Starting at the left-hand edge of each deck, there is the deck's name, consisting of the

name of the deck's host machine followed by a number and a letter, an 'R' to indicate a

record deck and a 'P' to indicate a play out deck. Next, for record decks, there is a MON

button, used to monitor the audio present at the deck input, followed by an ABORT
