Silicon Image’s M2VD-2HL* is designed to be used in system-on-a-chip solutions for
DVD and STB/DTV markets. With its extensive set of features M2VD-2HL enables companies
to easily provide functions like parallel viewing and recording, picture-in-picture or
simultaneous viewing of several channels in television, PC or other relevant environments.
The M2VD-2HL decoder is optimized to satisfy a wide range of applications and
technologies with optimal performance at lowest possible silicon costs. Its interfaces are
optimized for easy integration into a System-on-Chip architecture using the standard onchip
bus approach. This dramatically reduces the integration effort and enables fast
time-to-market developments.

Features
• ISO/IEC 13818-2 - MPEG-2 Main Profile @ High Level
• ISO/IEC 11172-2 - MPEG-1 constrained parameter set
• Support of all ATSC and DVB HDTV formats
• Real-time decoding of multiple streams only limited by frequency.
• Error detection and autonomous error concealment with concealment vectors on slice,
macroblock and block layer
• Counter for concealed MBs within a picture and threshold register which indicates the level
of interrupt generation
• Software access to relevant internal registers and parameter stores to provide the possibility
of a flexible error handling and a robust and error tolerant decoding control
• Decoding of Packetized Elementary Stream (PES) and Elementary Stream (ES)

Applications
• Set-top boxes
• Digital TV sets and IPTV applications
• DVD players and recorders
• Portable multimedia players
• Surveillance
