Frame Synchronisation A BNC connector accepts a composite video input to which the video output timing can be synchronised. 1.2.3 Outputs Transport Stream Outputs · Two BNC connectors output ASI Transport Streams with a maximum data rate of 160 Mbit/s. Video Outputs · · · Two analogue composite video outputs carried on BNC connectors. Two digital video outputs carried on BNC connectors. Audio Outputs Two 9-way D-type, female connectors decode two PES streams of audio from the Transport Stream. The audio outputs simultaneous analogue and digital. The digital mode can be changed via the user interface. Data Output · · · RS-232 asynchronous low-speed data output carried on a 9-way, D-type, female connector. RJ-45 high-speed data over Ethernet output (option). RS-422 synchronous high-speed data output carried on a 9-way D-type, female connector (option). Alarm Output A 9-way D-type connector for alarm and failure monitoring is carried out within the equipment. This produces a summary alarm signal and also lights the general front-panel ALARM LED. There is a 25-way D-type connector on the Alarm Relay Card (TT1260/HDC/ALRM) with six relays for failure monitoring for NCP over-air. The operator can define (using the Alarm Menu pages) which alarm conditions drive the relays. This is described in Chapter 5, Alarms and Annex C, Menus. Reference Guide: TT1260 Contribution Receiver ST.RE.E10100.1 Page 1-7 Introduction 1.2.4 Conditional Access and Scrambling The transport stream received by the IRD may be encrypted. The CA system is used to decrypt the required components of the transport stream so that they can be decoded. The following Conditional Access and Scrambling options are available for the TT1260 range of Satellite Receivers and Decoders: · · · · · · No Conditional Access Basic Interoperable Scrambling System, BISS Mode 1 and Mode E only. TANDBERG Director Remote Authorisation System (RAS) 1 and 2 Signal Protection DVB Common Interface BISS (as specified in EBU Tech 3292 May 2002) is standard on all Receivers/Decoders. The different CA options can be combined, for instance: · TANDBERG Director, RAS and BISS (however, streams with mixed CA are not supported) However, it is not possible to have both DVB Common Interface and TANDBERG Director on the same unit. When the CA system uses a smart card or Common Interface Module, access by the user is via the back panel of the IRD. 1.3 1.3.1 The Satellite Receiver Typical Satellite System The TT1260 Satellite Receiver is a component of the MPEG-2/DVB compliant range of TANDBERG Television equipment. It is designed for use by broadcasters and distributors of video, audio and data services over satellite. 1.3.2 Input Connections The Satellite Receiver interfaces directly to Low-Noise Block (LNB) and accepts an intermediate frequency (IF) input in the band 950 - 2150 MHz (L-band) for operation in the specified symbol-rate range (see Annex B, Technical Specification). The unit can provide dc power and polarisation switching to the LNB.

The input is down-converted via a Low-Noise Block (LNB) to provide an L-band input to the Receiver. The front-end tuning is microprocessor controlled with a frequency synthesised local oscillator. A software tuning and acquisition algorithm resolves translation errors (mainly due to the LNB). The signal is then passed to a demodulator that recovers the signal using soft-decision decoding. The resulting stream is Reed-Solomon decoded and descrambled to provide inputs to the Decoder circuit. The received channel may contain multiple services, therefore the Receiver's demultiplexer is configured to select a single video service and other audio/data components and present them at the output.

The new code is downloaded as a background task in the same transport stream as used for the normal transmission of services. Figure 1.4 shows the system required for this function. The existing software continues to function during the download process. Once all the new code has been received, installed and validated, it is loaded into the active memory and becomes the operating software for the Receiver.

For ATM AAL-1 E3 and ATM AAL-1 DS3 systems, two BNCs may be provided for full duplex operation. Reference Guide: TT1260 Contribution Receiver ST.RE.E10100.1 Page 1-11 Introduction 1.4.3 What the Decoder Does The ASI interfaces are used to present the transport stream in the format required by the internal Decoder circuitry. At this point, the operation of the unit is the same as the Satellite Receiver. The Decoder can be used to receive an input signal from a Public Telecom Network via a Network Adapter Unit (NAU). No error correction is supported at the input of the unit so a level of Quality of Service should be negotiated with the Telecom Network Provider. The Decoder is configured to select a single video service and other audio/data components from the multiple services on the incoming transport stream and present them at the output.

Once set up, the unit requires no further attention except to ensure the fan is working. There are up to four control modes associated with the Receiver (dependent upon options fitted). The unit remains in the chosen control mode until another mode is requested. NOTE... Local (Front Panel) Control is the factory default if TANDBERG Director is not installed. Page 1-12 Reference Guide: TT1260 Contribution Receiver ST.RE.E10100.1 Introduction 1.5.2 Front Panel (Local) Modes When operating the IRD from the Front Panel, there are two main operating modes: Navigate and Edit. See Section 3.3, Front Panel Operating Modes. Timeout (5 minutes) EDIT Off EDIT NAVIGATE EDIT On SAVE Figure 1.7: Front Panel States 1.5.3 Remote Control Modes RS-232/RS-485 Port The unit enters this state when the RS232/RS485 REMOTE port receives a configuration change command or the Remote control mode is selected in the System Menu (#6); see Section C.9, System Menu. The baud-rate of the network control is dependent upon the selected protocol. Local commands are ignored when the unit is in Remote Control mode. Network The unit will operate in a similar manner when the Network port is enabled to receive SNMP commands. The TT1260 must have its IP Address and Subnet Mask configured to conform to the controlling network.
