Broadcast
Broadcast is the tool for broadcasting the show. Here the presenter has a powerful tool with a bunch of features to build a high quality play list. Left alone Broadcast will run automated playing the play lists as they come from the scheduler or play the play lists as prepared by the presenter.

The play list

The play list will show a graphical view of the flow of the songs and other sound files. Also, you have time information about the next cue point or control event in the play list. Broadcast comes with two independent play lists, where the second play list is mostly used by the presenter for planning a coming sequence. The second play list can also be used for creating a completely different hour, for example for voice tracking to a night hour.

Voice tracking

Voice tracking is made in a monitor at the bottom of the play list, using only 4 key pressures to add the voice track, begin recording, set overlap for the next song and finish recording.

The monitor runs fully independent of the play list so you can make voice tracking and other adjustments while the play list is running and still keep the full overview of the play list.

Broadcast runs multiple overlapping sound files on a single standard sound card.

Advanced monitor

Advanced monitor is used when the monitor in the play list is not sufficient.

Advanced monitor is a multi track editor and as in any other editing in the Radiohost system the editing is non destructive. This means editing is made as a template on top of the sound file and you can always set the file back to its default settings with no lost of sound quality - even after 1.000 editings.

Groups and Timers

In the play list you can bundle some files together in a group. This means Broadcast will handle those files as one file. The group can be collapsed to show only one line in the play list.

Timers are used for synchronizing the play list to a time schedule by starting a file at a specific time. Used in conjunction with groups you can have timers acting several files before the timing must appear.

In the example, the file 14-Minha Galera is faded just in time to make the file 16-El Viento start exactly at 17.00. The files in the group will all play in full.

Triggers and Loop-record

The play list can be controlled by a remote signal. In its simplest form the trigger signal will play the next song, stop the play list, etc.

A more advanced control will be to have Broadcast listen for a remote signal between 17.54 and 17.56 to start a specific file in the play list.

If Broadcast is used as a master station it can send triggers for example at the start of the first commercial it can send a trigger to start the commercial blocks at the satellite Broadcasts. There will be a nice fade out/in when the commercials starts.

Loop-record is a feature used to mix an external radio signal into the play list. If the station is making all music, commercials, etc. but not the news. The news can be taken from the air and mixed into to play list. There will be no hard relay transition as the overlap has a fade out/in.

Hardware requirements

PC: Pentium 3 based and above.

Operating system: Windows XP, Windows 2003 Server, Windows 2000, Windows NT.

Sound card: Any standard sound card. At least two stereo are recommended with up to 4 stereo out puts as maximum. A cost effective card could be Terratech EWS88.

Hard disc: Many stations which have no separate file server choose to use the PC where Broadcast is running as a file server. The needed capacity is dependent of the number of titles you want to use in your system. For every 10 Gb hard disk you can have approximately 1.125 titles in Mpeg 3, 256 Kbit format.

Net card: 100 Mbit

Ram: 512 Mb
