ASI-IP-GTW User's Manual

Keep 204 bytes: Tick this box to transparently transmit all 204 bytes of the incoming ASI transport stream, if present. When only 188 byte packets are received or the box is unchecked, only 188 bytes of each transport stream packet is transmitted.

1.1.1.24 Input Status

Sync detected: Yes if the unit is receiving a valid DVB ASI stream on the ASI input interface. No if no DVB ASI stream is received.

Packet length: Shows the packet length of the MPEG2 transport stream packets received (188 or 204 bytes).

ASI total rate: Shows the bitrate of the MPEG2 transport stream on the input including NULL packets.

ASI effective rate: Shows the effective bitrate of the MPEG2 transport stream on the input i.e. bitrate excluding NULL packets.

1.1.1.25 IP TX Parameters

Enable IP transmission: Click this box to enable the MPEG-2 transport stream on the DVB ASI input to be sent through the IP network.

Protocol: Select UDP or RTP transmission mode. See 5.3.1 for more information on this

IP destination addr: Enter the destination IP address to use when transmitting data on the stream. The address may be either a unicast address or a multicast address.

UDP dest. port: Enter the UDP destination port to use when transmitting data on the stream. The UDP destination port is used by the receiver to separate one stream from another. UDP port numbers are in the range 1-65535.

Warning: Please ensure that there is no conflict in UDP ports in use. Pay special attention to the fact that FEC data are always sent on UDP port two higher than the media port and four higher than the media port, e.g., if UDP destination port is 5510, column FEC UDP port is 5512 and row FEC UDP port is 5514.

UDP source port: Enter the UDP source port to be used in the outgoing UDP frames for the current stream. UDP port numbers are in the range 1-65535. (Note that the ASI-IP-GTW receiver unit does not check this parameter when receiving streams)

FEC streams are transmitted with the same UDP source port as the media frames.

TS packets per frame: Enter the number of 188 byte MPEG-2 transport stream packets to map into each UDP frame. Valid values are between 1 and 7. We generally recommend using 7 when ASI-IP-GTW is used both at the sender and the receiver to reduce overhead. For very low bitrate streams, less than 7 packets per frame may be used to reduce the delay through the unit.
