Therefore, the Short FEC frame type should be selected in applications where latency is critical and the longer frame type should be used to optimize protection.

- Page 40 FTP is only useful for collecting logs from the device. How to Use API Commands The Adtec EN-31 device is unique in that it handles two physical encoders. To accommodate commands for controlling both encoders, you will need to specify which encoder you are working with for each command you issue.
- Page 41 How Video Rates are Configured (Example is pertinent to MPEG2) Video rates can be configured manually or automatically. The factory default is to automatically set the video rate based on TMR. This option is referred to as VAF (Video Autofill). VAF determines what the TMR is.
- Page 42 GO button. To disable EAS mode press the large STOP button. How to configure Network EAS Triggering By default, the EN-31 is configured to send an EAS trigger over the local network to all Adtec dual channel encoders (HDMI2QAM, YUV2QAM, EN-20 or EN-31). This feature can be disabled by unchecking the box next to “Network EAS Triggering”, then pressing the apply...
- Page 43 How passthru audio function - Dolby E / 5.1 / 2.0, Dolby D, LPCM The Adtec EN-31 encoder supports four pairs of audio encoding or two pairs of passthru per service. An audio passthru consists of a compressed bitstream ( Dolby E 20 Bit / Dolby E 16 Bit / Dolby Digital / Linear Acoustic Stream Stacker 2 ) or an uncompressed stereo pair ( LPCM ) from embedded SDI passed into the egress transport stream ( IP, *RF, ASI ).
- Page 44 not being presented on the corresponding input. The SDI matrix can be changed to each pair without restarting the encode session. Once hash is heard, then a compressed bitstream should be present. Set the mode back to Passthru for the automatic detection mechanism to configure the Dolby type and bitrate.
- Page 45 ○ Even if Service 2 is set to OFF, Service 1 can still only allocate 50% of the Audio resources Encoding: The EN-31 has the following Audio Encoding capabilities and resources. Different CODECs require a different amount of resources. The EN-31 has logic built-in so that the user cannot exceed the audio resources. CODEC MODE...
- Page 46 The important thing is to be aware of different configurations and how resource intensive they are. If an EN-31 is not accepting the settings being submitted, then check the other pairs of audio and ensure the threshold is not being exceeded.
- Page 47 How to use ASI Remux Terminology: “ASI Remux” refers to the ability for an Adtec EN to accept a Transport Stream (TS) via ASI input, and multiplex the incoming service or services with it’s locally encoded service. The result is that the transport stream output becomes a MPTS containing the services from the ASI input in addition to the locally encoded service.
- Page 48 PMT - Program Map Table. This MPEG-2 table specifies PID values for components of programs. The Adtec EN-3X and EN-100 encoders have an ASI input available for the ASI remux feature. Further information can be read about ASI Remux in the ASI Remux article. In some cases, users may want to add custom PID’s from third party generators, such as a DVB Subtitles, into...
- Page 49 As EN encoders do not perform PID conflict resolution at this time, the PID’s inserted into the system should not conflict with other PID’s utilized by the EN-31. To configure ASI Passthrough of DVB subtitles, visit the Manual PIDs tab. This tab contains PMT template entries that will be used to insert into the PMT.
- Page 50 The user will then need to map the entry into the associated PMT by visiting the Manual PID Mapping tab. The Italian DVB Subtitle PID was entered into the first manual PID configuration. This can be mapped by moving the associated PID from the ‘Unmapped PIDs’ box into the ‘Mapped PIDs’...

- Page 52 Vertical Interval Time Code Vertical Interval Time Code (VITC) is typically used in transmissions that require time code from the originating source to be preserved. It was originally developed for analog television recording systems, but has new standards for transmitting in digital systems (SMPTE-12M-1 / SMPTE-12M-2).
- Page 53 How to setup a Zixi IP stream on the Adtec Encoders The Zixi technology can be used to enhance the stability of an IP stream when the network is not in a controlled environment. The use of FEC and latency allows the receiver to request any missing packets and the encoder to resend as needed.
