    • The devices come under protection classification I. It is absolutely necessary, therefore, to insert the mains plug into a fused socket. • Warning Connecting external video sources of which the mass has a different potential from that of the EMA 207 may cause “wow” (avoided by matching the potentials or isolating them from each other). 1.2 Contact If there are any questions or problems, help is available from: BLANKOM Antennentechnik GmbH Hermann-Petersilge-Str.

    It can be sent either to a cascaded EMA 207 or to a downstream modulator. By cascading EMA 207 devices (up to 8), a transport stream with up to 32 services can be produced or these services can be added to an incoming transport stream.

    Making the connections: The PC and the EMA 207 must be connected to the network using an Ethernet cable. If the EMA 207 is connected directly to the PC, a cross-link Ethernet cable must be used. To establish the connection, the IP addresses of the devices must first be matched up.

    Part N : 9172.x1 LINE That of the EMA 207 is 192.168.2.86 on delivery. The address of the network connection in the PC must be adapted to the IP address of the EMA 207 (subnet mask: 255.255.255.0, IP address: 192.168.2.XXX). Do not let XXX be exactly the same as the IP address of the EMA 207. When cascades are being configured initially, it is necessary to ensure that there is always only one EMA 207 connected to the network, as the IP addresses of all the devices are identical on delivery.
  • Page 9 EMA 207 MPEG-2 ENCODER/ MULTIPLEXER SDI/ A/V → ASI(TS) Part N : 9172.x1 LINE Status 19x: The status pages regularly deliver updated internal information for maintenance checks on the status and functioning of the device. They also can called up directly by input of IP address followed by page number. E.g. the input status delivers the page 190: “http://192.168.2.86/190.htm“.
  • Page 10 Transfer of the PC‘s settings Date and time on the device. Download MIB: With this function, a MIB parameter file can be downloaded from the EMA 207 to the PC. The file is used to configure the sy- stem via SNMP .

    When programmes or transponders are being forwarded, the origin of the data can be indicated here by inserting the “origi- nal” network ID for purposes of information. Cascade Number within Network: [1 ... 8] The number of the cascade is inserted here to distinguish between the EMA 207 cascades installed. It must be the same num- ber for all the EMA 207s of a cascade and it serves to generate unique programme numbers (designated by service ID) within a network.

    EMA 207 MPEG-2 ENCODER/ MULTIPLEXER SDI/ A/V → ASI(TS) Part N : 9172.x1 LINE Program Name: This is where a programme name is allocated for each encoder input port. The programme name will be displayed by the set- top box. The programme name must be unique and may appear only once in a cascade of encoders. The maximum length is 16 characters.

    Although the standard allows 1 to 8 frames, this range is not supported from every connectable audio device with an ASI TS input port known to BLANKOM. This, with an inappropriate combination of frame value and audio bitrate, can lead to sound problems (for example, periodic breaks).

    • Transport stream identification (TS ID) Unique identification of the transport stream is generated. The TS ID can be any number between 1 and 65 535. However, at the start the TS ID will be the 5-digit serial number of the EMA 207 being initia- lised. In the simplest case, the TS ID of the first device should also be entered for all the devices.
  • Page 17 VTX: Teletext internally generated. The EMA 207 has the facility that a teletext carrousel can be generated for each particular device. This teletext can be allocated to one or all of the services being shown. This is an optional function and a charge is made for it.

  • Page 18: Transport Stream Bit Rate (Ts Out Bitrate), System Bit Rate

    The bit rate (“TS-Out bit rate”) is selected in the configuration settings under Channel Mux. For the EMA 207, the maximum TS-Out bit rate possible is 214 Mbps. When deciding the TS-Out bit rate it is necessary and im- portant to check what is the maximum transport stream bit rate which can be processed or forwarded by succeeding compon- ents such as modulators and upconverters.

    The EMA 207 can select any pair of signals from these and embed them in the DVB transport stream. 3.4.3 Options The EMA 207 can access the signals when processed in a variety of ways. If there is a need for further functions, it is always possible to enquire about them (section 1.2, contact).

    Ethernet connections of the HCB x00 and the EMA 207 are networked. Before this happens, the “lo- west” of the IP addresses of all the EMA 207 encoders must be entered in the configuration menu for the IP address of the HCB x00. It is only possible to enter (or change) IP addresses into the HCB x00 directly.
