GT 26 Tangram module IP to 4x ISDB-T
Category : Tangram
The GT26 module is part of the Tangram product portfolio. The GT26 module allows you to add up to 4 channels in ISDB-T format per module to your network. Tangram is a very high density and highly flexible solution for all kinds of networks. The WISI Tangram chassis uses a fully redundant concept (n+1, 1+1).
- High quality IP to ISDB-T modulation
- Up to 4 ISDB-T channels on 2 RF outputs
- For measurement / monitoring test ports of the output signal
- Outstanding signal parameters by direct digital modulation
- RTP/ IP input streaming with FEC error correction
- DVB/ARIB transport stream processing
- Output detection for alarming and redundancy switching
- Up to 24 ISDB-T channels in 1 RU
