  • Page 12: The Dee28 Card

    4 The DEE28 Card The DEE28 is a next generation Dolby multi format decoder and Dolby Introduction E encoder with quad speed ADD-ON audio bus. It replaces the popular DBD08 and DBE08 on a single card. Based on the Dolby’s Cat. No. 1100 sub module it is capable of decoding Dolby E, Dolby Digital and Dolby Digital Plus and encoding to Dolby E.

  • Page 13: Applications

    Program Procedure This card can be updated with new firmware when new firmware versions are released by Axon. You can download the .spf file from our website when new releases are announced. To upgrade the DEE28 you can follow the instructions as described in the ‘reprogramming cards quick-guide’, downloadable via our website.

    DEE28 and enables the item to be changed or adjusted. Settings can be changed using the front panel of the Synapse frame (SFR18, SFR08 or SFR04) or Axon Cortex. Please refer to chapter 3 for information on the Synapse front panel control and Axon Cortex.

  • Page 15: Dolby_Pcm_Backup

    Dolby_firmware Please only change to No_Update when told so by Axon Support. Output_1_mux ~ With these setting you can choose to either route the default channels to Output_4_mux the output muxes (CH1/2 for output 1, CH3/4 for output 2, CH5/6 for output 3 and CH7/8 for output 4) or to route the encoded Dolby E signal to the specific output.

  • Page 16: Ch_Backup

    Ch_backup With this setting you appoint specific channels within the input source set with Dolby_PCM_backup, which should contain Dolby E. Dependant on the source, you can choose any of the audio pairs listed under Ch_E_in. Sel_Ch1 ~ Sel_Ch16 With these settings you set a source for the corresponding output channel.

  • Page 17: Delay_Ch_1/2 ~ Delay_Ch_15/16

    Delay_CH_1/2 ~ These settings allow you to delay the audio of each pair of channels in a Delay_CH_15/16 range of 0 to 1300 ms. In steps of 0.01 ms. Default is 0ms. IN BUS CONTROL Override 17/24 If you want to pass processed audio from one quad speed add-on card to the other (for instance if you want to pass decoded Dolby E audio from this card to for instance a Loudness Control or Dolby D encoder add-on card next to this card) you have to use this setting.

  • Page 18: Vo_Sel

    VO_Sel Here you set a source which contains the voice over channel. Can be set to Local (physical AES/EBU inputs), Master (audio coming from master card via add-on) or Decoded_PCM (audio coming from the Dolby decoder). Default is Local. VO_Ch Here you select which channel in the above selected source contains the voice over content.

  • Page 19: Meta_Bus

    OUTPUT CONTROL Slot1/2 ~ Slot31/32 These menu items are to fill the Quad speed audio bus with the appropriate outputs. You can fill any of the 16 audio pairs (32 channels in total) with the audio that is set to Out1/2, Out3/4, etc till Out15/16.

  • Page 20: Pcm_Metadata

    PCM_metadata With this setting you decide whether you want to keep generating metadata in case the Dolby E is lost. Default is off. PCM_latency Here you define the delay in case the Dolby signal is lost. Can be set to SingleFrame (equal to Dolby E decoding) or to minimum.

  • Page 21: Ad_Mix

    DOLBY D+ DEC (refer to appendix 2 for decoded Dolby Digital channel mapping) If the decoder receives an input stream with AD program content, mixing Ad_mix occurs according to the input stream mixing metadata. The user has the option of routing the mixed audio, main audio (Main_only), or associated audio to the main output (AD_only).

  • Page 22: Loud_Prgm

    functionally equivalent to LKFS, but represents a confusing discrepancy between the ITU and EBU. Another new concept introduced by R 128 is the Loudness Range (LRA) descriptor. Loudness Range is essentially a measure of the spread of loudness measurements throughout a program, measured in Loudness Units (LU).
  • Page 23  MOM (momentary loudness): This parameter provides the loudness measurement for the last 400 milliseconds, and does not use any gating for the measurement.  INT (integrated loudness): This parameter provides a single, simplified measurement value for the loudness over the entire program.

  • Page 24: Main_Drc_Dd

    10s loudness With this setting you decide whether you want to apply the dynamic Main_DRC_DD range (None (Dialnorm), RF mode or Line mode) to the output signal of the decoder when the input is Dolby Digital. With this setting you decide whether you want to apply the dynamic Main_DRC_E range (None (Dialnorm), RF mode or Line mode) to the output signal of the decoder when the input is Dolby E.

  • Page 26: Bitstrm

    Bitstream describes the audio service contained within the Dolby Digital. #Bitstrm A complete audio program may consist of a main audio service (a complete mix of all program audio), an associated audio service comprising a complete mix, or one main service combined with an associated service.

  • Page 27: Dialogue_Lev

    Commentary This is typically a single channel program intended to convey additional commentary that can be optionally decoded along with the main audio service. This service differs from dialogue services because it contains an optional, rather than required, dialogue channel. The service may also be complete mix of all program channels, comprising up to six channels.

    RfMode has the same options as Line, but each option is 11 dB more #RfMode sensitive to avoid overloading the RF input of a television. Possible are: None, Film stnd, Film light, Music stnd, Music light and speech. Default is None. #D Srnd Dolby Surround.

    7 Events Menu Introduction An event is a special message that is generated on the card asynchronously. This means that it is not the response to a request to the card, but a spontaneous message. What is the Goal of The goal of events is to inform the environment about a changing an event? condition on the card.

  • Page 37: Defining Tags

    The Tag The tag is also defined in the card. The tag has a fixed meaning. When controlling or monitoring software should make decisions based on events, it is easier to use the tag instead of interpreting a string. The first implementation is the tag controlled switch in the GPI16.

  • Page 44: Quad Speed Add-On Bus

    Appendix 1 Quad speed ADD-ON bus The internal audio ADD-ON bus needed an upgrade for some applications. We wanted more channels (32 per video stream seem possible in the near future). And we want the bus to be bidirectional, so 32 channels in and 32 channels out at the same time.
  • Page 45 audio bus  Every Quad-Speed ADD-ON card takes 32 channels from the ‘right hand ADD-ON card’ and adds (or overwrites) the local processed channels.  This can be done for any of the channels that are processed in the ADD-ON card ...

  • Page 46: Some Examples

    The maximum amount of ADD-ON cards in Quad Speed mode is 3. These 3 ADD-ON cards will run all on the same clock in the same phase as the MASTER-CARD. This guarantees that audio channels that are processed in different ADD-ON cards will still operate in the same phase, something very important when processing multiple discrete surround channels.
  • Page 47 Another example of the Quad-Speed audio ADD-ON bus shows a transmission application where a dual up/down/cross output card is connected to a DIO88 in a setup where the embedded audio combined with external audio and a convenient PCM monitoring is available. In the following example (next page) you will see a 4 card application that performs a massive amount of processing divided over 1 MASTER-CARD and 3 ADD-ON cards.
