Zapex recently introduced the ZP-330 and 230 MPEG-2 video and audio encoders for digital compression. A new Program Stream feature allows for the encoders' use in broadband and streaming applications, while the Transport stream is used for broadcast and cable applications. The ZP-330 is able to encode video and Dolby digital audio simultaneously. On-board transport stream multiplexers enable users to feed output from the encoders into a DVB card.
Encoder chips improve image quality and reduce bit rates by using multiple algorithms to examine every macro-block. Automatic scene change detection enables the encoders to eliminate block artifacts by detecting subtle changes in the video.
