[. . . ] A configurable number of 188-byte MPEG-2 TS packets are mapped straight into a UDP frame with no additional overhead. The MTU for Ethernet is usually 1500 bytes. This limits the number of MPEG-2 TS packets per UDP frame to lie within one to seven. The IP layer is according to RFC791 Internet Protocol Specification. Figure 6. 2 shows a more detailed picture of the MPEG-2 data transfer. TS-packets are mapped in a datagram, using User Data Protocol (UDP), Internet Protocol (IP) and Ethernet. 188 . . . 188 TS packets (1 to 7) UDP datagram IP datagram 8H 20 H Information Information 14H Information Ethernet frame Figure 6. 2: Building the Ethernet Frame Page 6-6 Reference Guide: TT1260 Contribution Receiver ST. RE. E10100. 1 Options 6. 2. 7 ATM AAL-1 E3 Telco Input (TT1260/HWO/ATM-E3) This provides transmission of MPEG2-TS packets (respectively RS coded MPEG2-TS packets) over PDH links using ATM cells, this particular version uses E3 style PDH framing. 6. 2. 8 ATM AAL-1 DS3 Telco Input (TT1260/HWO/ATM-DS3) This provides transmission of MPEG2-TS packets, respectively RS coded MPEG2-TS packets, over PDH links using ATM cells, this particular version uses DS3 style PDH framing. 6. 2. 9 4-Input 16 QAM/QPSK (TANDBERG) Input (TT1260/HWO/HOM) The HMO Card is a 16QAM, 8PSK, QPSK, BPSK input module. This card provides a complete digital front-end board for DVB-S, DSNG and other contribution applications and support 4 L-band inputs The HOM card provides a method of receiving new code via the TT1260's debug interface, this takes the form of an FTP download into the TT1260. The 16 QAM and 8PSK modes of operation are only available if purchased by the customer (this takes the form of a customisation licence key). 6. 2. 10 High Speed RS-422 Data Input (TT1260/HWO/HSDATA) High-speed data (synchronous data) can be carried in a transport stream as private data. This is then extracted from the transport stream and output from the IRD via an RS-422 interface or Ethernet. 6. 2. 11 Alarm Relay Card (TT1260/HDC/ALRM) General The Alarm Relay Card has six additional relays. The alarm relays are programmable to reflect the state of one or more of the individual monitored alarm conditions. NOTE. . . Without this option, only the summary alarm is available. 6. 3 6. 3. 1 Software Enabled Options Licence Keys These options may be enabled through software licence keys. Contact the Customer Services Helpdesk for details (see Preliminary Pages). Reference Guide: TT1260 Contribution Receiver ST. RE. E10100. 1 Page 6-7 Options 6. 3. 2 High Speed Data Over Ethernet (TT1260/SWO/HSETHER) The IRD can be enabled through a licence key to output high-speed data over the Ethernet port. The IRD uses the Data-Piping protocol to de-encapsulate the data received. The data must be carried as private data on a designated transport stream PID. Careful consideration needs to be taken to ensure interoperability with the transmitting equipment. 6. 3. 3 6. 3. 4 6. 3. 5 6. 3. 6 6. 3. 7 8PSK Software Licence (TT1260/SWO/8PSK) Software key licence for TT1260/HWO/HM, enabling QPSK and 8PSK. 16QAM Software Licence Software key licence for TT1260/HWO/HM, enabling QPSK, 8PSK, and 16QAM 4:2:0 Operation (TT1260/SWO/420) Allows only 4:2:0 operation. Low Symbol-rate Operation (TT1260/SWO/LSYM) Software key enabling low symbol-rate operation. SNMP Enabling (TT1260/SWO/SNMP) Enable SNMP protocol for use with TANDBERG TDC and nCompass control systems. 6. 4 6. 4. 1 6. 4. 2 Conditional Access RAS Mode 1 Conditional Access (TT1260/SWO/RAS) This option enables RAS Mode 1 conditional access descrambling. RAS Mode 2 Conditional Access (TT1260/SWO/RAS2) This option enables RAS Mode 2 conditional access descrambling. 6. 4. 3 6. 4. 4 BISS-1 and BISS-2 (TT1260/SWO/BISS) This option enables BISS functionality. Director Functionality (TT1260/SWO/DIR) This option enables Director functionality. Page 6-8 Reference Guide: TT1260 Contribution Receiver ST. RE. E10100. 1 Chapter 7 7.
