AtlasGear AG-3803 Receiver Decoder Card
Sencore's AtlasGear is a series of receiver/decoder cards with multiple channel, high-density, multi-format decoding capabilities. The AtlasGear AG-3803 8-VSB/ASI to ASI/Composite Receiver / Decoder Card enables providers to receive ATSC broadcast signals and output those signals via ASI and Composite Video.
Overview
Sencore's AtlasGear is a series of receiver/decoder cards with multiple channel, high-density, multi-format decoding capabilities. The AtlasGear AG-3803 8-VSB/ASI to ASI/Composite Receiver/Decoder Card enables providers to receive ATSC broadcast signals and output those signals via ASI and Composite Video.
The AtlasGear series of receiver decoder cards are used within the openGear™ chassis. With AtlasGear and the open architecture of the openGear™ system, the multi-format decoding functionality of Sencore's award winning Modular Receiver Decoder (MRD) can be easily integrated with a wide range of solutions available from multiple companies each specializing in their own technologies.
Features
Multi-Format SD/HD MPEG2 & H.264 Decoder
Future proof off-air turn around applications with multi-format support on one card.
Composite Video Output
Output Composite Video with the re-created NTSC VANC data (closed captions, XDS [from 608 data or from PSIP tables] and AMOL/Gemstar [SCTE 127]).
Manual or AFD Triggered Downconversion
Fix the output format to the preferred center-cut, letterbox, or anamorphic modes. Or, switch formats on the fly with support for the Active Format Descriptor (AFD).
ASI Input
Automatic redundency switching from 8-VSB to ASI from off-air to fiber fed back-up.
ASI Output
Simultaneous ASI output to facilitate transport stream analysis or as an input directly to a stat-mux.
Remote Access
View multiple chassis and multiple cards simultaneously with the DashBoardTM application. Integrate monitoring and control into any network management system with the available SNMP MIB.
