ASi-5 is to provide a set of up to 1536 binary inputs and 1536 binary outputs per Ethernet address. 1.2 ms cycle time can be achieved by the system for up to 24 participants. This fast cycle time allows new fields of applications that were previously reserved for expensive network systems. 96 participants can be addressed in an ASi-5 network.
The ASI output of a DVB Integrated Receiver/Decoder (IRD). It carries the entire MPEG transport stream being received from a DVB satellite feed entering the RF input (far left side in picture). Asynchronous Serial Interface, or ASI, is a method of carrying an MPEG Transport Stream over 75-ohm copper coaxial cable or optical fiber. [1]
The various serial digital interface standards all use (one or more) coaxial cables with BNC connectors, with a nominal impedance of 75 ohms. This is the same type of cable used in analog composite video setups, which potentially makes for easier "drop in" equipment upgrades (though may be necessary for long runs at the higher bitrates for older oxidising or lower grade of cable to replaced ...
The "stop bit" is actually a "stop period"; the stop period of the transmitter may be arbitrarily long. It cannot be shorter than a specified amount, usually 1 to 2 bit times. The receiver requires a shorter stop period than the transmitter. At the end of each character, the receiver stops briefly to wait for the next start bit.
The Advanced eXtensible Interface (AXI) is an on-chip communication bus protocol and is part of the Advanced Microcontroller Bus Architecture specification (AMBA). [1] [2] AXI had been introduced in 2003 with the AMBA3 specification.
EIA-170/RS-170 applies only to monochrome (black & white) video. The later color video version is RS-170A which shows color burst and the 4 color field sequence of NTSC. The RS-170A version is only a tentative standard, and was never formally adopted. NAB Engineering Handbook Seventh Edition. [1] EIA-189A Formerly RS-189A.
An application-specific integrated circuit (ASIC / ˈ eɪ s ɪ k /) is an integrated circuit (IC) chip customized for a particular use, rather than intended for general-purpose use, such as a chip designed to run in a digital voice recorder or a high-efficiency video codec. [1]
