AL-D200 Decoder IP

Allegro DVT’s AL-D200 is a silicon proven, multi-format, multi-stream real-time hardware decoder IP core, optimized for 4K@30fps resolution. The AL-D200 decoder IP has an optional support for 4:2:2 color decoding allowing support for professional video applications such as video contribution and transcoding. In addition, its unique scalable architecture offers a highly configurable and flexible design, meeting the requirements for small area and high performance of applications such as:

• Video contribution and transcoding
• Set-Top Boxes, Digital TV
• Smartphones and tablets
• Automotive
• Camera SoCs
