====== 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.

===== Encoder Summary =====

^ Encoder ^ Hostname ^ VLAN 240 IP ^ VLAN 100 IP ^ VLAN 111 (Multicast) ^ iDRAC IP ^
| Encoder 0 | Titan | 172.17.240.141 | 10.10.1.19 | 192.168.3.139 | - |
| Encoder 1 | Titan | 172.17.240.139 | 10.100.1.18 | 192.168.3.129 | 10.100.1.49 |
| Encoder 2 | Titan2 | 172.17.240.132 | - | 192.168.3.102 | 10.100.1.13 |
| Encoder 3 | Titan3 | 172.17.240.133 | 10.100.1.133 | 192.168.3.103 | 10.100.1.14 |
| Encoder 4 | Titan (Lenovo) | 172.17.240.134 | 10.100.1.134 | 192.168.3.134 | - |

===== 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 [[vyos|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

# From local machine, jump through NTT-Media1
ssh -J mmunger@68.66.14.158 titan@172.17.240.141  # Encoder 0
ssh -J mmunger@68.66.14.158 titan@172.17.240.139  # Encoder 1
ssh -J mmunger@68.66.14.158 titan@172.17.240.132  # Encoder 2
ssh -J mmunger@68.66.14.158 titan@172.17.240.133  # Encoder 3
ssh -J mmunger@68.66.14.158 titan@172.17.240.134  # Encoder 4
