7.11 Video Port Interface (VPIF)
The DM6467T Video Port Interface (VPIF) allows the capture and display of digital video streams.
Features include:
• 150-MHz VPIF
• Up to 2 Video Capture Channels (Channel 0 and Channel 1)
– Two 8-bit Standard-Definition (SD) Video with embedded timing codes (BT.656)
– Single 16-bit High-Definition (HD) Video with embedded timing codes (BT.1120)
– Single Raw Video (8-/10-/12-bit)
• Up to 2 Video Display Channels (Channel 2 and Channel 3)
– Two 8-bit SD Video Display with embedded timing codes (BT.656)
– Single 16-bit HD Video Display with embedded timing codes (BT.1120)
The VPIF capture channel input data format is selectable based on the settings of the specific Channel
Control Register (Channels 0–3). The VPIF Raw Video data-bus width is selectable based on the settings
of the Channel 0 Control Register. For more detailed information on these specific Channel Control
Registers, see the TMS320DM6467x DMSoC Video Port Interface (VPIF) User's Guide (Literature
Number SPRUER9).
7.11.1 VPIF Bus Master Memory Map
The VPIF peripheral includes a bus master interface that accesses the DM6467T system bus to transfer
video-capture and video-display data. Table 7-44 shows the memory map for the VPIF master interface.

7.11.2 VPIF Clock Control (Capture and Display)
The source clocks for the VPIF data channels are selectable based on the settings of the VIDCLKCTL
register (0x01C4 0038) (For the VIDCLKCTL register details, see Section 4.3.2.1, Video Clock Control
Register). The VSCLKDIS register (0x01C4 006C) is used to disable the clock inputs when changing the
clock source to ensure glitch-free operation. (For the VSCLKDIS register details, see Section 4.3.2.3,
Video and TSIF Clock Disable).
For both the VPIF dual 8-bit or 16-bit video-capture modes, Channel 0 is always clocked by VP_CLKIN0
(see Figure 7-34).
Figure 7-34. VPIF Capture Channel 0 Source Clock
Video-Capture Channel 1 is clocked by the VP_CLKIN1 signal, when the dual 8-bit capture mode is
enabled. When the 16-bit capture mode or 8-/10-/12-bit raw-capture mode is used, VP_CLKIN0 must be
selected as the clock source (VIDCLKCTL.VCH1CLK = 0) [see Figure 7-35].
