Product Description

Product Description

OTV-IPAM2 2U chassis high density analog modulator can ingest multiple HD or SD IP streams in either MPEG-2/ H.264 /H.265 format and convert them to PAL-B/G, PAL-DK, PAL-I, PAL-M, PAL-N, NTSC modulated RF analog outputs for delivery to legacy analog TV networks.

It can decode MPEG-2, H.264 and H.265 encoded video streams in SD and HD quality. In case of HD decoding, automatic downscaling to SD resolution is performed. Numerous audio formats and modes can be decoded and modulated on TV channels.

OTV-IPAM2 ensures a high agility inside the whole RF output frequency range. This enables full flexibility and makes the most efficient use of the available channel spectrum. This allows operators to support legacy analog tiers of service while simplifying headend equipment and power consumption and integrating with modern IP video headend architectures.

Main Features:

  • 4 GE ports (max 64 IP input over MPTS/SPTS), Max 840Mbps for each GE input
