Overview
The Atria Logic AL-MPEG2E-SW is a software-based, low power MPEG-2 Main Profile video encoder IP core, targeted for mobile and non-mobile, low power devices in industrial and medical applications. Industrial applications include broadcast contribution portable video recorders and train/bus/truck/airplane black box recorders. Medical applications include operating theater recorders, as well as PACS video archiving.
The encoder supports MPEG-2 Main Profile at Low and Main Level IPB encoding up to SD resolutions, and supports both single-pass variable bit rate (VBR) and constant bit rate (CBR) encoding. Support for rate distortion optimization for mode decisions provides exceptional video quality at low bit rates. The encoder is fully MPEG-2 standards compliant.
The implementation includes power-optimizing algorithms that enable the encoder to run at very low power in a Linux or MS Windows environment on a wide range of ARM processors, such as ARM7, ARM9, ARM9E and ARM11, as well as on the EZchip Tilera TilePro64 processors.
