The DMP-BDT700 Blu-ray player Panasonic is the top model of this year. It can play Blu-ray 2D and 3D 1080p but 4K 2160/24p and 2160/60p videos and JPEG photos 4K. It simply includes a SoC that brings the latest UniPhier MN2WS0220 developed by Panasonic with management 4K upscaling 4K 24p, 50 or 60 im / s, and a Dual Core ARM Cortex-A9 MPCore to provide a very powerful video processing with reduction jitter, and 4K Chroma Direct Up Conversion with treatment against the Ringing Effect, but we do not yet know all the intricacies and possibilities. There is a safe bet that found improvement filters details and contours, one or two Noise, and a filter to improve the upscaling.
The audio portion thus consists of four high-end DAC (apparently developed by Panasonic) capable of handling 192 kHz and 32 bits. There are also two HDMI 2.0 compatible 2160/60p, 2160/24p, and 1080p/24p and to separate the audio and video signal. There are also all kinds of audio processing as a Remaster 96 khz (upsampling) Dialogue Enhancement, setting levels, crossover, speaker distance, etc.. (As BDT500 2012). The chassis has been redesigned, more solid, all-aluminum, treated against vibration and isolated from EMI / RFI. According to my source, power is linear, but this remains to be confirmed.
For the rest, there is a media management via USB, UPnP and Samba (client / server) and support for MKV, MP3, FLAC 5.1 192/24, 4K JPEG, XviD, AVCHD, M2TS, and TS, the new interface Panasonic internet, applications tens, the Miracast compatibility, a web browser and Wi-Fi and Wi-Fi integrated Direct.
