Standard Definition Decoders

Stradis offers a full line of standard definition MPEG2 decoders with a variety of outputs and additional features. Models range from the full-featured SDM290ex which offer multi-channel audio, LTC, RS422 control, and other advanced features to the SDM230 which offers analog video outputs and a single pair of unbalanced analog audio outputs. Since all models are completely software compatible you can choose the one that best fits your application. All models provide a powerful decoding solution with a wide array of features.

• Begin playback of a stream at any I-Frame.
• Decoding of streams up to 50Mbps with 4:2:2 or 4:2:0 chroma formats.
• Hardware synchronization of audio and video timing

Audio

• Decoding and uncompressed output of MPEG-1 Layer 1, 2, and 3 audio formats.
