  • Page 9: Introduction

    WISI 's Inca Multiscreen Launch Platform (MLP) is a high-density transcoder with integrated HLS packager and origin server. The Multiscreen Launch Platform is based on the Inca Modular Series 4400 with the 4420 two bay chassis. The Multiscreen Launch Platform transcodes up to 12 HD or 24 SD channels to multiple bitrate profiles and features both automatic packaging and origin server capable of serving up to 2 Gbps of HLS data, reaching up to 500 clients at 4 Mbps.

    3. Deploying the Multiscreen Launch Platform 3.2.2 Video Network Source and output video are in MPEG-2 transport stream format. Output video is the transcoded video which is output to the multicast video network, making it available for inspection, prior to packaging for HLS delivery. The transcoded outputs are typically UDP multicast, which allows any host connected to the video network to access the streams.

Transcoding sources with excessive decode delay can result in loss of associated audio. WISI Support may recommend enabling the Audio Delay Compatibility Mode, which will make the multiplexer wait for audio during excessive decode delays.

This setting is only required if legacy Broadcom PVR equipment is being used with output streams from WISI transcoders. When enabled, it is applied to all output streams that use the V2 data pathway on the chassis and these streams will be reformatted to be compatible with legacy Broadcom PVRs.

  • Page 94: Redundancy

    12. Redundancy 12. Redundancy WISI offers the Service Failover redundancy option on the Multisceeen Launch Platform. Service failover redundancy enables configuring a secondary source to replace a primary source in the same chassis, when one or more of up to six user-configured trigger conditions are detected. When the trigger condition on the primary source clears, the system automatically returns service to the primary source.

  • Page 95: Service Failover

    12. Redundancy 12.1 Service Failover In service failover, the system monitors up to 16 PIDs in the primary source used to generate an output. Up to six parameters can be monitored, with user-configurable thresholds. The system can be configured to automatically fail over to a user-specified secondary source when any of the trigger conditions are met.
  • Page 96 12. Redundancy Service failover is accessed by selecting Edit in the drop-down menu in the source or output section of the desired output tile, then selecting the Monitor/Failover tab, as shown in the screenshots below. Figure 12.2 - Select Edit in the Source Portion of the Tile Figure 12.3 - Select Edit for an Output Monitor/Failover configuration in the source region of the tile applies to the tile’s first output.

    This field specifies one or more PIDs to monitor in the source selected in Monitor mode. Up to 16 [Textbox] PIDs can be specified. PIDs are specified using WISI filter expressions, separated by commas. Several example expressions are provided below. For more examples of filter expressions see...
  • Page 98 12. Redundancy For transcoded outputs, service failover monitoring can take place either before or after the transcode process, using the Watch the source or Watch the transcoder output options. The selected monitor mode determines where the secondary source will be substituted in the signal flow, in the event of a failover.
  • Page 99 12. Redundancy Watch the transcoder output In Watch the transcoder output mode, monitoring and secondary source substitution take place after the transcode processor. The substituted secondary source is output directly, without being transcoded. Figure 12.6 - Transcoded Outputs – Watch the Transcoder Output Up to six parameters in each of up to 16 selected PIDs in the primary source can be monitored.
