ADV601LC is an ultralow cost video codec that supports precise compressed bit rate control, field independent compression, and an 8-bit video interface compatible with CCIR-656 and multiplexed Philips formats. It has a general purpose 16- or 32-bit host interface with a 512 deep 32-bit FIFO. The codec is capable of real-time compression or decompression of CCIR-601 digital video with compression ratios from visually loss-less to 350:1. It is suitable for applications such as PC video editing, remote CCTV surveillance, digital camcorders, digital video tape, wireless video systems, and TV instant replay.
The ADV601LC is an ultralow‑cost, single‑chip video encoder/decoder that compresses and decompresses CCIR‑601 digital video in real time. It integrates video and host interfaces with on‑chip SRAM, offering 100 % bit‑stream compatibility with the ADV601 and supporting a range of applications such as PC video editing, CCTV surveillance, and digital camcorders.
The device features a 16‑/32‑bit host interface with a 512‑position, 32‑bit FIFO, a wavelet‑based compression engine, programmable quantizer, and run‑length/Huffman entropy coders. It complies with CCIR‑656 and multi‑plexed Philips formats, provides compression ratios from visually loss‑less to 350:1, and operates at up to 13.5 MHz pixel rate for PAL and NTSC video standards.
