Fission HDCore On Air Monitor Module

Many broadcasters around the world are obliged by law to maintain transmission recordings of aired content.  Besides having the resulting media available for any official inquire, it also helps broadcasters clarify issues regarding transmission of advertisement materials. Broadcasters themselves can identify possible transmission problems in their output chains. The On Air Monitor (OAM) Module is Fission HDCore’s compliance recording system.

In order to correlate the signal recordings with the transmission metadata, almost all compliance recording solutions need to import an “As-Run Log” flat file, and calibrate in accordance with the existing playout solution time reference. Usually this is a time consuming and manual process that involves a certain margin of error. If the existing Playout solution is Fission, the On Air Monitor will be tied to the system’s database, the correlation process is non-existent. The Transmission Report section of the OAM provides the following information for every playlist event, such as playout server, channel name, on air date and time, programmed date and time, time difference, on air duration, programmed duration, duration difference, operator, house number, content name and source, filename, path, and the corresponding content segment.

The On Air Monitor allows for immediate access to the compliance recorded media based on the element selected in any such transmissions report.  There are search tools that allow a user to easily identify aired content. Any compliance recorded media segment can be exported for further action.

Detached Storage

Recorded material can be stored within the OAM server’s local storage, including DAS, or in external storage such as NAS or SAN.

Storage Upkeep

In order to keep recording when the available disk space is running low the OAM is capable of automatic purge and move operations, based on user established rules.

Multi-Channel Server

A server can host up to 6 server capture services. Each channel’s recording and upkeep settings can be configured independently, without any restriction against other input channels.

Multi-User Environment

Several users can simultaneously check the captured media from different locations using Fission’s OAM Viewer.

Segment Export

Fission OAM is able to export media clips from in and out points set on any date and time needed.

Live Monitoring

The recording inputs available in each On Air Monitor module are monitored through the use of independent live windows.
