AB Television

Project Description

Paris (France). SI Media has recently been selected by AB Television, one of the main private television operators in France, as the supplier of a system consisting in 2 HD channels.
The system manages the emission on-air of two thematic channels in HD format: AB Golf Channel, dedicated to the notorious sport, and AB Lucky Jack Channel, which presents a playlist focused on poker playing.
This involves a distributed system, with the main play out carried out from a datacenter based in Luxemburg, while the disaster recovery system (Backup), capturing and the preparation of the playlists are carried out in Paris, in the main branch of AB Television Company.

 

The play out occurs in HD format 1080i and the chosen containers for clip management are MXF and GXF. Indeed, the choice of GXF format is necessary due to the need to continue using the enormous already-existing archive, entirely in SD and GXF.

 

The adopted video server is based on a custom solution which foresees a local cache in Raid-5 and a Matrox board X.MI02/12/8000/S which is capable of manage until the point of capturing and two contemporary output channels from the same machine.

 

Another two video servers with the same configuration operate in Paris. These intervene in case of fault of the main video server working in Luxemburg, but are also used as the ingestion channels from live sources and/or tapes both operating in XDCAM-HD format.

 

The Media Asset Management supplied by SI Media is capable of distributing the clips planned by the playlists in the three video servers, archiving new clips in the central archive, and recovery, if need be, of necessary clips into the video servers. Other than the ingestion from external sources (lives and tapes), it is also possible to import clips from watch folders, and taking advantage of the MAM capacity, to recognise the new clips and to recover the necessary metadata: name, duration, TCIN, TCOUT, Aspect Ratio, description, etc. The playlists are created with the traffic application called Karina, entirely developed by the AB Television development team.

 

This large interfacing project from both parts has allowed Karina to connect to the SI Media database thanks to a gateway (MediaLinker) developed by SI Media.

 

With this in mind, SI Media has supplied to the Customer a complete solution for its Master Control Room, including:

 

    • MediaStore: HSM module for exchanging assets between the NearLine archives working in Paris (Hitachi NAS for 120TB) and Luxemburg (Hitachi NAS for 40TB) and between each NearLine archive and its connected video servers (GammaRed VS based on Matrox X.MIO2 enc/dec board with 6TB of local cache).
    • MediaLinker: module for exchanging data (playlist, as run log, asset metadata, ingestion list) between MS SQL 2008 R2 database and Karina broadcast management system (BMS).
    • MediaPlay and  MediaPlayBK: 2 playout channels in Luxemburg and their own redundancies in Paris, both of them working in 1:1 configuration.
    • MediaRec: two modules for capturing tasks each one of them with the remote control of the A/V router in order to select the right source for ingestion.
    • MediaDevice: module dedicated to the management and control of the devices involved into the automation: A/V Router, Logo generator, Character generator.

 

In this installation the low resolution clips (WM9 at 1.5 Mb/s is the selected format and bit rate for this purpose) are automatically generated by MediaStore Proxy, the transcoder application supplied by SI Media.
The system, other than the three video servers and numerous clients, involves 2 Hitachi Central Archives (one of 40TB in Luxemburg and one of 120TB in Paris), 4 CG and logo generators Cast Genie supplied by Anywhere Video (2 main and two backup), 2 Harris SD/HD A/V Router.
