Broadcast Quality, Multi Channel, Frequency Agile, 2 RU 8VSB or QAM (Combination) Tuner/Demodulator with DVB-ASI Output. Ideal for Digital Turnaround at Cable Head Ends, by Feeding the ASI Outputs into Modulators for Transmodulation. These Modules are also Suitable for Remote Receivers Where the Outputs are Encapsulated into IP.

Broadcast Quality, Multichannel, Real Time, Standard or High Definition (up to 1080i), Integrated RF Receiver, and MPEG-2 to H.264 or H.264 to MPEG-2 Transcoder, Scaler, and Standards Converter. Based on Embedded Linux®, it Boots Quickly from Flash Drive and Remembers all Settings. Easy to Use GUI Allows Full Config of Each Stream and via SNMP can Report its Status to Remote Network Operations. Will Transcode and Process Multiple Streams up to CPU Limitations. Typical Dedicated Transcodes are up to 15 SD Streams, 3 1080i Streams, and 4 to 6 720p Streams. There is a Version with IP In and Out. Audio Support is AAC (MPEG-4), Ogg Vorbis, or AC-3 Passthrough.
