Denon displayed their two upcoming Blu-ray players at IFA, the DVD-2500BT and DVD-3800BD. Unfortunately the Denon representatives couldn't offer much details about the players, but both players will support Blu-ray Profile 1.1, which means that they will come equiped with secondary video/audio decoders to enable picture-in-picture functionality. The BD players will also feature HDMI 1.3a and are backwards compatible with DVD and CD.
The main difference between the two players is that the DVD-3800BD does internal decoding of the audio, while the DVD-2500BT only supports output of the HD audio bitstream to an external decoder. The DVD-3800BD also comes equiped with Silicon Optix Realta HQV video processor for deinterlacing and upconversion of standard definition to HD. We weren't able to get confirmation if the DVD-3800BD will support internal decoding of Dolby TrueHD and DTS-HD Master Audio, but they stated that it was very likely. The DVD-3800BD also features Dynamic Discrete Surround Circuit-HD (DDSC-HD), which is a sound circuit designed by Denon to offer high-quality surround sound.
