Ateme Titan Live Encoders

The NTT Sacramento data center runs 5 Ateme Titan Live encoders that transcode DirecTV multicast streams received from Vantiva COM3000 receivers into HLS/DASH streams for TiVo distribution.

Network Architecture

Each encoder has 3 network connections:

VLAN 111 (Multicast) - Receives DirecTV multicast from Vantiva COM3000 (192.168.3.x)
VLAN 240 (Encoder) - Outputs transcoded streams to NTT-BGP1 for multicast to TiVo
VLAN 100 (Internal) - Management and SDI/video input

Hardware

Encoders 0-3: Dell R-series servers
Encoder 4: Lenovo server
