6.1.8.2. Audio Metadata Bundle Bit-Fields

The Audio Metadata (AM) packet carries additional information related to 3D Audio and Multi-Stream Audio (MST).

The core sends the AM packet on the active edge of the V-SYNC signal to ensure that the packet is sent once per field. The signal bundle of audio_metadata[165:0] is clocked by vid_clk.

Table 17.  Audio Metadata Bundle Bit-Fields for Packet Header and Control

The following table lists the AM signal bit-fields for packet header (as described in the HDMI 2.0b Specification Section 8.3) and control.

Bit-field Name Description
0 3D_AUDIO
  • 1: Transmits 3D audio
  • 0: Transmits MST audio
2:1 NUM_VIEWS Number of views for an MST stream
4:3 NUM_AUDIO_STR Number of audio streams - 1
165 Control Disables the core from inserting the AM packet.
  • 1: The core does not insert audio_metadata[164:0]. The AM packet on the Auxiliary Data Port passes through.
  • 0: The core inserts audio_metadata[164:0] when audio format[3:0] is 3D audio or MST audio. The core filters the AM packet on the Auxiliary Data Port.
Table 18.  Audio Metadata Bundle Bit-Fields for Packet Content when 3D_AUDIO = 1

The following table lists the AM signal bit-fields for packet content when 3D_AUDIO = 1 (as described in the HDMI 2.0b Specification Section 8.3.1).

Bit-field Name Description
9:5 3D_CC Channel count of the transmitted 3D audio
12:10 Reserved Reserved (0)
16:13 ACAT Audio channel allocation standard
20:17 Reserved Reserved (0)
28:21 3D_ACAT Channel/Speaker allocation for 3D audio
164:29 Reserved Reserved (0)
Table 19.  Audio Metadata Bundle Bit-Fields for Packet Content when 3D_AUDIO = 0

The following table lists the AM signal bit-fields for packet content when 3D_AUDIO = 0 (as described in the HDMI 2.0b Specification Section 8.3.2).

Bit-field Name Description
5 Multiview_Left_0 Left stereoscopic picture (Subpacket 0 in MST Audio Sample Packet)
6 Multiview_Right_0 Right stereoscopic picture (Subpacket 0 in MST Audio Sample Packet)
