GENERAL DESCRIPTION
The ADV601LC is an ultralow cost, single chip, dedicated function, all digital CMOS VLSI device capable of supporting visually loss-less to 350:1 real-time compression and decompression of CCIR-601 digital video at very high image quality levels. The chip integrates glueless video and host interfaces with on-chip SRAM to permit low part count, system level implementations suitable for a broad range of applications. The ADV601LC is 100% bitstream compatible with the ADV601.
The ADV601LC is a video encoder/decoder optimized for realtime compression and decompression of interlaced digital video. All features of the ADV601LC are designed to yield high performance at a breakthrough systems-level cost. Additionally, the unique sub-band coding architecture of the ADV601LC offers you many application-specific advantages. A review of the General Theory of Operation and Applying the ADV601LC sections will help you get the most use out of the ADV601LC in any given application.
