The WISI TANGRAM video platform is a high-density digital TV headend for contribution of digital TV via IP networks and end-to-end IPTV solutions such as video-on-demand, connected TV and OTT (Over The Top) or Web TV. The platform is highly customizable and offers advanced DVB stream processing in a small footprint 1 RU chassis concept. The TANGRAM chassis can be equipped with 6 + 1 modules. The six rear loaded modules have different functionalities, and can perform all necessary signal processing functions.
- Small footprint in 1RU chassis
- Hot swappable fan tray
- Fully redundant concept (1+1, n+1)
- Optional scrambling and multiplexing function
- Redundant power supplies ensure operational capability
- Each module can be equipped in every slot
