The organization of this document is based directly on the organization and section numbers contained in version 1.4a of the HDMI Specification. Information has been extracted from version 1.4a of the HDMI Specification with no change to section numbers. Resolution of Conflicts This document strives for consistency with the HDMI Specification. However, in the event of any conflicting provisions between this document and the HDMI Specification, the provisions set forth in the HDMI Specification shall prevail. Please Note: Use of the HDMI Vendor Specific Data Block and HDMI Vendor Specific InfoFrame as defined by the HDMI 1.4a Specification ensures interoperability. Non-compliant use of the HDMI Vendor Specific Data Block and HDMI Vendor Specific InfoFrame can create interoperability problems. High-Definition Multimedia Interface Specification Version 1.4a HDMI Licensing, LLC Page 5 of 28 8 Control And Configuration 8.2.3 HDMI Vendor Specific InfoFrame This is a CEA-861 Vendor Specific InfoFrame containing a 24-bit IEEE Registration Identifier of 0x000C03, a value belonging to HDMI Licensing, LLC. The content of this InfoFrame is defined by this specification. The transmission of this InfoFrame is optional for the source device. But if a source device outputs a video signal which is defined in this section 8.2.3, the source shall transmit this packet. Whenever this packet is transmitted, an accurate HDMI Vendor Specific InfoFrame shall be transmitted at least once per two Video Fields. It is optional for a Sink to interpret this packet. The data in the AVI InfoFrame packet remains valid even if the HDMI Vendor Specific InfoFrame is transmitted. The packetization of this HDMI Vendor Specific InfoFrame is defined below.

The value of “0000” means the Frame packing structure described in this section. The value of “1000” means the Side-by-Side (Half) structure described in this section. The value of “0110” means the Top-and-Bottom1 structure described in this section. For other values, see Appendix H (Table H-2). Table 8-13 3D_Structure Value Meaning 0000 Frame packing 0001 ~ 0101 Reserved for future use 0110 Top-and-Bottom 0111 Reserved for future use. 1000 Side-by-Side (Half) 1001 ~ 1111 Reserved for future use For Side-by-Side (Half), the original left and right pictures are sub-sampled to half resolution on the horizontal axis. Sub-sampled pictures are arranged in Side-by-Side layout. See Figure 8-5. For Top-and-Bottom, the original full left and right pictures are sub-sampled to half resolution on the vertical axis. Sub-sampled pictures are arranged in Top-and-Bottom layout. See Figure 8-6.  3D_Ext_Data [4bits] The meaning of this field depends on the 3D_Structure value. If 3D_Structure is 1000 (Side-by-Side (Half)), the 3D_Ext_Data field is added in the HDMI Vendor Specific InfoFrame and shall be 00XX (i.e. from 0000 to 0011, horizontal sub-sampling). For other values, see Appendix H. If 3D_Structure is 1001~1111, the 3D_Ext_Data field is also added and indicates additional information about the 3D format. If 3D_Structure is 0000~0111, the 3D_Ext_Data field shall not be present. 8.2.3.2 3D video format structure The 3D video format is indicated using the VIC (Video Identification Code) in the AVI InfoFrame (indicating the video format of one of the 2D pictures, as defined in CEA-861-D or Table 8-4) in conjunction with the 3D_Structure field in the HDMI Vendor Specific InfoFrame (indicating the 3D structure). Frame packing is one of the HDMI 3D video format structures indicated by the 3D_Structure field and is composed of two stereoscopic pictures: Left and Right, defined as shown in Figure 8-3. 1 In this specification the term “Top-and-Bottom” is used to describe this 3D structure; it is equivalent to the term "Over-Under" that is often used in other literature.

This Active space area shall be encoded in the same manner as the adjoining Active video regions. During the Active space, an HDMI Source shall transmit a constant pixel value. HDMI Sinks shall ignore all data received during the Active space regardless of the value. Frame packing may also be applied for interlaced video timing formats. Figure 8-4 shows the 3D structure for interlaced video timing formats.
