DVB-ASI - Digital Video Broadcast- Asynchronous Serial Interface
DVB-ASI is a serial video communications standard defined by the DVB consortium for use in transporting MPEG-2 encoded video streams. The standard is most commonly used to connect cable head-end equipment that transports MPEG-2 streams. Data is transported at a rate of 270 Mb/s. A complete discussion of DVB-ASI specifications is provided in EN 50083-9: Cabled Distribution Systems for Television, Sound and Interactive Multimedia Signals, available from ETSI. Implementation of multiple channels of DVB-ASI are possible in Xilinx FPGAs and typically result in substantial cost savings versus ASSP-based solutions. When integrated with SDI and HD-SDI, the FPGA becomes a true connectivy platform for all kinds of applications handling compressed and uncompressed video.

What is the difference between ASI and SDI in Video?
In digital video broadcast (DVB), SDI is Serial Digital Interface an uncompressed form of A/V signal and ASI is Asynchronous Serial Interface an compressed form of A/V signal. The SDI signal hold the pids(audio, video, subtitle ...) of one channel, ASI can hold pids from multiple channels and in some cases (satelite uplink) some pids who describe the transponder(NIT, TID...)
