In terms of video connections, the BDP-430 offers a single HDMI output, as well as component and composite video outputs. (Players released after January 1, 2011, are no longer allowed to have HD-capable component video outputs, due to copy-protection restrictions; the Pioneer models got in just under the wire with their December release.) The player supports 1080p/60 and 1080p/24 output resolutions via HDMI, but it does not include a Source Direct mode that outputs all sources at their native resolution (a feature that formerly appeared on many Pioneer models).
On the audio side, outputs include HDMI, optical digital (no coaxial), and stereo analog. The BDP-430 has onboard Dolby TrueHD and DTS-HD Master Audio decoding, and it also passes these high-resolution audio formats in bitstream form over HDMI, for your A/V receiver to decode. The player lacks multichannel analog audio outputs, so the only way to pass decoded high-resolution audio formats is via HDMI. The BDP-430 features Pioneer's PQLS technology to eliminate jitter in both stereo and multichannel sources when you mate the player with certain Pioneer receivers.
The BDP-430 supports BD, DVD, CD audio, AVCHD, Divx, WMV, MKV, MP3, WMA, and JPEG playback. You can add the player to your home network either by using the back-panel Ethernet port or by attaching the optional AS-WL200 wireless LAN adapter ($99) to the back-panel USB port. This USB port also supports the addition of a USB drive to store BD-Live content; the player does not have internal memory for BD-Live storage. A second, front-panel USB port also supports BD-Live storage and media playback. As I mentioned above, the BDP-430 lacks an RS-232 port, as well as IR ports, for integration into an advanced control system.
