DVB-ASI: Asynchronous Serial Interface as specified by DVB standard

Asynchronous Serial Interface was specified by DVB, dedicated at conveying bit serial MPEG2 transport streams over long distances, high noise tolerant (typically for satellite applications, for example). Using a 75 ohms coaxial cable, ASI standard allows to interconnect two devices more than 300 meters far from each other, with data rate up to 214 Mbps (line transmission rate of 270 Mbps with 8B/10B data encoding).
Two functional modes of ASI do exist : burst mode, or continuous mode. In burst mode (also called packet mode), a complete MPEG2 packet can be sent at maximum rate (214 Mbps), then transfer is paused until the next packet of data is ready to be transmitted. In continuous mode (also called byte mode), data bytes are spread out evenly in time, leading to an instantaneous data rate approaching the average data rate. ASI interface is widely used by broadcasting professionals, since it combines cost effective and easy to use cabling, and large bandwidth.
 

ASI - LVDS These Interfaces convert an MPEG2 transport stream (DVB or ATSC) from DVB-ASI to DVB-SPI - LVDS (Low Voltage Differential Signal) - or the other way around. Enter the section to get available references

ASI - LVDS/TTL Interfaces here convert an MPEG2 transport stream (DVB or ATSC) from DVB ASI to LVDS and TTL (both formats are supported in the same box) or the other way around. Enter the section to get available references.

ASI - M2S Interfaces here convert an MPEG2 transport stream (DVB or ATSC) from DVB-ASI to M2S (as specified by Harmonic / Divicom) or the other way around. Enter the section to get available references.

ASI - M2P Interfaces here convert an MPEG2 transport stream (DVB or ATSC) from DVB-ASI to M2P (MPEG2 Parallel Interface from Harmonic / Divicom) or the other way around. Enter the section to get available references.

ASI - RS-422 ENENSYS has one interfacing product able to translate signals from DVB-ASI to RS-422 interface (RS 422 is a proprietary format from NDS). Enter the section to get available references.

ASI - USB 2.0 ENENSYS product range also includes high end interfaces that adapt ASI with high speed USB 2.0 bus. These come with software applications (stream player or stream recorder/ real time analyser). Enter the section to get available references.
