Overview:

IndigoVision’s Mainstream™ MPEG-4 silicon-verified video encoder IP adds high-performance MPEG-4 video encoding to existing systems. It is particularly suited to adding video encoding capabilities to cameras and other portable, battery-powered devices, such as mobile phones and PDAs.

The Mainstream™ MPEG-4 video encoder is fully compliant with the MPEG-4 Simple Profile standard. The encoder also contains support for some Advanced Simple Profile (ASP) tools for higher performance and can encode arbitrary resolutions up to full ASP Level 5 (D1/DVD) resolutions, all at full frame rate.

Based on the single clocked, synchronous, fully hardware pipelined Mainstream™ architecture the encoder requires minimal intervention from a host processor and can be controlled by a low-cost, low-power processor such as in an ARM or MIPS based SOC. The encoder is provided as a reduced footprint standalone module for encode-only applications, or where separate encoders and decoders are the preferred solution.

Features:

  • MPEG-4 Video Encoder

    • Fully compliant ISO 14496-2 MPEG-4 Simple Profile L0, L1, L2, L3

    • Compliant Advanced Simple Profile tools
