DP564 Multichannel Audio Decod er A-1 Appendix A Metadata Note: This appendix was originally written for users of Dolby ® E products that assign metadata parameter values. The DP564, as a decoder, sim ply uses the metadata parameters included in a Dolby Dig ital bi tstream.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-2 decoder processes the metadata stream ac cording to parameters set by the program creator, as well as cer tain settings for bass m anagement and dynamic range that are chosen by the consumer to reflect thei r specific home theater equipm ent and environmental conditions.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-3 transparent to consumers, certain parameters affect the output of a home decoder, like when downmixing for a specific speaker configuration, or when the consumer chooses Dynamic Range Control to avoi d disturbing family and neighbors.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-4 Both types of metadata can be exam ined, modified, or passed through during encoding. Table A-1 lists the active metada ta param eters and indicates if each parameter is inform ational or control.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-5 When received at the con sumer’s Dolby Digital decoder, this param eter setting determines the level shif t in the decoder that sets, or normalizes, the average audio output of the decoder to a preset level.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-6 The most important point to remember is th at in setting the dialogue level parameter, you are providing your listener with an esse ntial service. For y our listeners, setting this level properly means: • The volume level is consiste nt with other programs.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-7 Note: While the use of DRC modes during decoding is a consumer-selectable feature, the dialogue level parameter se tting is not. Therefore, the proper setting of the dialogue le vel parameter is essential before previewing a DRC profile.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-8 Dynamic Range Control Profiles Six preset DRC profiles are available to content producer s: Film Light, Film Standard, Music Light, Music Standard, Speech, and None. Each is applied in the pattern shown in Figure A-2.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-9 • Music Standard Max Boost: 12 dB (below –55 dB) Boost Range: –55 dB to –31 dB (2:1 ratio) Null Band Width: 5 dB (–31 dB to –26 d.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-10 It is important to consider the output signals from each piece of equipment that can receive a Dolby Digital program in the hom e.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-11 In each of these devices, the analog stereo output is one of two different stereo downmixes.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-12 Extended BSI parameters translate seamlessl y to decoders that read only universal parameters. A.5.1 Universal Parameters Universal parameters are present in a ll Dolby Digital encoders and decoders.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-13 LFE Channel The status of the LFE Channel pa rameter indicates to a Dolby Digita l encoder whether an LFE Channel is present within the bitstream . Channel Mode determines whether the LFE Channel parame ter can be set.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-14 Bitstream Mode Setting Definition Complete Main (CM) CM flags the bitstream as the Main Au dio Service for the program and all elements are present to form a c omplete audio program. Currently, this is the most comm on setting.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-15 RF Overmodulation Protection This parameter is designed to protect against overmodulation when a decoded Dolby Digital bitstream is RF modulated. When enabled the Dolby Digital encoder includes pre-emphasis in its calculations for RF Mode compression.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-16 Surround Downmix Level Setting Defini tion 0.707 (–3 dB) default The left and right surround channels are each attenuated 3 dB and sent to the left and right front channels, respectively. 0.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-17 environment matches that of the m ixing room. This control operates in add ition to the dialogue level control, and is best th ought of as the final volum e setting on the consumer’s equipment.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-18 Note: The parameters DC Filter , Lowpass Filter , LFE Lowpass Filter , Surround 3 dB Attenuation , and Surround Phase Shift appear after the Extended BSI parameters on Dolby E and Dolby Digital equipment m enus.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-19 Surround 3 dB Attenuation The Surround 3 dB Attenuation paramete r determines whether the surround channel(s) are attenuated 3 dB before en coding. The attenuation actually takes p lace inside the Dolby Digital encoder.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-20 Because the revised definitions affect metada ta param eters that were not used by the consumer decoders, all decoders will be co m patible with the revised bitstream .
DP564 Multichannel Audio Decod er Appendix A: Metadata A-21 Lt/Rt Surround Mix Level This parameter indicates th e level shift applied to th e surround channels w hen downmixing to an Lt/Rt output. Its operati on is sim ilar to the surround downmix level in the universal metadata .
DP564 Multichannel Audio Decod er Appendix A: Metadata A-22 Lo/Ro Surround Mix Level This parameter indicates th e level shift applied to th e surround channels w hen downmixing to a Lo/Ro output. When Exte nded BSI param eters are active, this parameter is used, and the Surround Mix Leve l parameter in the universal param eters is not.
DP564 Multichannel Audio Decod er Appendix A: Metadata A-23 A.6 Metadata Combinations Table A-3 provides examples of combinations of parameters that could be used as a preset.
