c

Product Name: Four Channel MPEG-2 Compression Encoder (WDE-2420)

The WDE-2420 4-in-1 encoder is an easy-to-use and powerful MPEG-2 encoder. Supports analog composite videos as well as mono or analog stereo sound. The compressed data output format is ASI/SPI. Compression method MPEG-2 MP@ML The encoder encodes up to 4 audio and video signals in real-time and multiplexes them to generate 1 MPTS multi program transmission stream. Fully compliant with MPEG-2 standards, with strong compatibility. Its volume is a 1U chassis, and it can be fully set up and operated offline through the front panel LCD display screen.
