Application
The DVB-ASI input card converts a MPEG stream (SPTS or MPTS) with a constant TS rate
from 1.5Mbps up to 170Mbps to an ATM cell stream, either using AAL1 (ATM Adaptation
Layer 1, with or without FEC) or AAL5 (rtVBR). For protection switching on ASI level the card
provides 2 inputs and an integrated A-B switch. An automatic and seamless protection
switching will be performed in case of LOS (Loss of Signal) on ATM side or a loss of the
MPEG TS input signals.
The card supports ASI burst and packet mode as well as TS packet sizes of 188 and 204
Byte. In case of 204 Byte packets a correction of the TS packet can be performed based on
the integrated Reed-Solomon (RS) processor. The MPEG RS can be stripped off or
transported transparently.
According to the user configuration the MPEG TS packets are mapped to AAL1, AAL1 with
FEC (ITU-T I.361.1) or AAL5 (ATMF VoD 2.0). The resulting ATM cell stream is shaped by
the use of an extended Dual-Leaky-Bucket algorithm to assure an equidistant cell
distribution. The ATM traffic is sent over 2 high-speed serial links supporting redundant
network interfaces and protection switching.
The card can be configured by using the console port (RS232) or in combination with an
installed controller card via the 2 redundant Ethernet ports. All configuration parameters are
stored locally and non-volatile. The entire function of the module is controlled by the onboard
CPU. The firmware is stored in the on-board Flash memory.
The card supports hot-plug and hot-swap according to the Compact-PCI specification.
