  • Page 1 - Receives DVB-T2/T/C TS & converts into ASI & IP in real time. Sophisticated End Users and OEMs - Records TS using Free application DVSStationIP. the AT88IP is an ideal solution for a - Web based Software as well as DVSStationIP. number of applications such as: - DVSStationIP runs on Windows XP, Vista, Windows 7.
  • Page 2: Block Diagram

    The block diagram of the AT88IP device. 2 EXTERNAL INTERFACES The external interfaces for the AT88IP are shown. There are two F-Type RF connectors, a Mini BNC connector for the DVB-ASI output, a RJ45 connector with two LEDs, a Power Supply Inlet and a Power Switch.
  • Page 3: Installation

    Connect the AT88IP & the PC/laptop to your network DHCP server. Connect the power adaptor & Power up the AT88IP using the switch on the rear of the unit. You should see the Power LED is ON and the 2nd LED ( Status1 ) BLINKING.
  • Page 4 When you update the firmware you must wait for the process to complete without any interruptions. If the updating is interrupted, by disconnecting it from the network or powering it down, the device will no longer have a valid firmware & no longer operates. © 2017 Alitronika DVS AT88IP www.alitronika.com...

Below are presented the main points on MPEG2 TS over IP Encapsulation set by DVB-IPI. All MPEG-2 transport streams shall be encapsulated in RTP (Real-time Transport Protocol) according to RFC 1889 in conjunction with RFC 2250.
  • Page 14: Forward Error Correction

    Forward Error Correction The Pro-MPEG Forum (association of broadcasters, program-makers, and vendors) approved an open standard to improve QoS in professional video over IP networks, while keeping interoperability between equipment manufacturers. Standard is provided as a set of guidelines and recommendations (Codes of Practice). Code of Practice #3 describes a Forward Error Correction (FEC) method for protection against errors in delivering professional MPEG-2 TS data over IP networks.
  • Page 15 Appendix2 - Multicast All Alitronika IP devices have the capability to transmit or receive a transport stream by unicast, multicast or broadcast. This appendix describes the multicast settings. 2.1 Multicast Transmit In order to enable multicast transmit, the target IP address must be set to a value in the multicast range. The multicast range is from 224.0.0.0 to 239.255.255.255.
  • Page 16 2.3 RIGMP Querier The join and leave multicast group messages belongs to the IGMP protocol. Most switches have a timeout at the multicast group table. The timeout can be named “Host timeout” or “Aging timeout”. At the timeout the multicast group is cleared and multicasting stops. To avoid this the following can be done: •...
