Physical media remains superior to streaming in terms of image quality and uncompressed sound. This Panasonic Ultra HD Blu-ray player incorporates an in-house video processor, support for the main HDR formats, and an audio section compatible with high-resolution files. It is designed for 4K disc playback and use in advanced home theater installations.
The HCX processor at the service of the image
At the heart of the player, the HCX processor (for Hollywood Cinema Experience) handles the decoding and processing of Ultra HD Blu-ray discs. Its most tangible function lies in 4K Direct Chroma colour processing, which reconstructs 4:2:0 colour signals into 4:4:4 to reproduce finer textures and a better sense of depth. DVDs and 1080p Blu-rays benefit from 4K upscaling that gains in sharpness without making the image harsh.
The 4K output reaches up to 60p in 4:4:4 via HDMI 2.0, and the player respects the original 24p film frame rate, avoiding judder introduced by conversion to 50 or 60 Hz. Ultra HD Premium certification, Deep Colour and the expanded colour space complete a solid video foundation, whether the source comes from a disc or a file played over the network.
Four HDR formats and brightness control
Few players cover all four HDR families available on the market. The DP-UB820AFK decodes HDR10, HDR10+, Dolby Vision and HLG, bringing together both dynamic metadata formats in a single device. This matters depending on the discs and TVs you own, as not every format is supported by every display.
The HDR Optimizer function adjusts the luminance curve for TVs and video projectors with limited peak brightness, where the disc’s tone mapping does not always match the display’s actual capabilities. On a non-HDR TV, the player converts the signal to SDR while preserving the expanded BT.2020 colour space when the display supports it, limiting colour loss compared with a simple switch to REC.709. The output dynamic range level can be adjusted manually according to the TV’s brightness.
Dual HDMI output and connectivity
Two HDMI ports are located on the rear, a feature that sets this player apart from most models in its category. The first carries the image to the TV or video projector, while the second sends sound to the home theater amplifier. This separation is useful with an older amplifier without an input compatible with recent video streams, and reduces interference between circuits. HDMI Low Clock Jitter processing improves clock stability to preserve the audio signal.
On the audio side, the player features a digital optical output and a 7.1-channel analogue output on RCA, useful for connecting an amplifier without an HDMI input or for directly using the internal converters. Connectivity is completed by an Ethernet port, built-in Wi-Fi and two USB ports, one on the front in USB 2.0, the other on the rear in USB 3.0.
An audio section open to high resolution
The audio section is based on a 32-bit digital-to-analogue converter capable of processing files up to 192 kHz. The player decodes Dolby TrueHD, Dolby Digital Plus, DTS-HD Master Audio and high-resolution DTS-HD streams, and can also transmit them as bitstream to an amplifier that handles them. For file playback, it supports FLAC up to 192 kHz / 24-bit, WAV and AIFF up to 384 kHz / 32-bit, ALAC, as well as DSD up to 11.2 MHz.
Panasonic adds two in-house processing modes that shape the sound rendition. Digital Tube Sound reproduces the behaviour of a tube stage to soften treble, while Surround remastering broadens the soundstage, both active up to 192 kHz / 32-bit. Audio CD playback and access to network-shared files via DLNA are also included.
However, the player leaves out two formats: it plays neither SACD nor DVD-Audio, which some music enthusiasts still seek. For a more sophisticated analogue section, with dedicated power supply and balanced XLR outputs, the flagship model in the same range goes further; the DP-UB820AFK favours a balance between performance and modest dimensions.
Discs, files and everyday use
Disc compatibility covers virtually all media on the market: Ultra HD Blu-ray, 2D and 3D 1080p Blu-ray, DVD and CD, including BD-R and BD-RE recordable discs. Via USB, the player recognises the main video containers, including MKV and MP4 in H.264 or HEVC, high-resolution audio formats and JPEG images. Network playback via DLNA provides access to files from a home server, with one known limitation: changing audio tracks in certain MKV files and decoding high-resolution audio tracks do not always work over the network.
At 430 mm wide, 63 mm high and weighing 2.2 kg, the player remains compact and lightweight, with a less substantial chassis than higher-end reference models. Its responsiveness is the other compromise: powering on, loading an Ultra HD disc and navigating chapters require a little patience. In operation, power consumption is around 32 W, dropping to 0.3 W in standby when network standby is disabled.
LAN (Ethernet): yes (for Ultra HD Blu-ray, DLNA, BD-Live and firmware updates)

Frequently asked questions
Does the DP-UB820AFK play SACDs and DVD-Audios?
+
No. These two physical audio formats are not on its compatibility list. It does, however, play audio CDs and a wide range of high-resolution files from a USB drive, hard drive, or network.
Does the player have a coaxial audio output?
+
It features an optical digital output, but no coaxial output. For analog connection, the 7.1-channel RCA output and the stereo output allow you to connect an amplifier that lacks an HDMI input.
Does voice control work without a connected speaker?
+
No, it goes through a speaker or a compatible Amazon Alexa or Google Assistant device. Without this relay, control is done with the included remote control.
Can both HDMI outputs stream video and audio simultaneously?
+
Yes, depending on the output mode selected in the settings. The video output can carry both picture and sound, while the dedicated audio output feeds the amplifier. This setting is mainly used to separate the streams when the amplifier does not support the latest video signals.
Does the player support 3D Blu-ray?
+
Yes, it plays Full HD 3D Blu-ray discs as well as AVCHD 3D files. A 3D-compatible TV or projector is still required to enjoy them.
Is an internet connection essential for operation?
+
No, not for disc playback, which does not depend on any network. The wired or Wi-Fi connection is used for video streaming, the BD-Live feature on certain Blu-rays, DLNA playback on the local network, and firmware updates.
What equipment do you need to fully enjoy 4K HDR?
+
A 4K HDR-compatible TV or projector, Ultra HD Blu-ray discs, and a high-speed HDMI cable. The dual HDMI output also allows you to route audio to a separate amplifier from the screen, which remains optional for a simple setup.

Perfect in terms of quality and consistent in its menus, but the menu looks like it's from the 2000s. No effort made on that front, which is a shame given the price of the player.
What matters is that the audio and video quality is flawless.

Parfait pour la qualité et cohérent dans ses menus mais par contre, menu des années 2000. Pas de travail de ce côté là ce quinest dommage vu le prix du lecteur.
Ce qui compte c'est que la qualité audio et vidéo est irréprochable.

The player has otherwise been really good, but initially the device's fan made an annoying noise as it resonated against the casing. This was a problem especially during quiet scenes in movies/quiet passages in music, as it could be clearly heard all the way to the sofa (about 2.5m away). The root cause was that the fan is attached with only two screws, with no damping material in between. I solved the problem by slightly loosening the fan screws (the screw heads are on the outside of the casing), which allowed me to push it back a little. After that, I inserted some heat-shrink tubing through the grille between the fan and the casing and tightened the screws again. This stopped all the extra noise, and the device now works as it should.
Besides movies, I also use the player as a CD player. The player has worked really well for both uses, and I've had nothing to complain about (after solving the fan problem). If I hadn't managed to solve the fan problem, I would have sent the player back. Though I don't know whether a new player would have been any better, since it's partly a design flaw, with the fan attached using too few screws. Luckily, this little DIY trick solved it.

Soitin on ollut muuten tosi hyvä, mutta ensi alkuun laitteen tuuletin piti häiritsevää ääntä, kun se resonoi koteloa vasten. Tämä oli ongelmana erityisesti elokuvien/musiikin hiljaisissa kohtauksissa, kun kuului selvästi sohvalle asti (n. 2.5m päähän). Juurisyynä oli se, että tuuletin on kiinnitetty vain kahdella ruuvilla, eikä siinä ollut mitään vaimennusmateriaalia välissä. Ratkaisin ongelman löysyttämällä hieman tuulettimen ruuveja (ruuvinkannat kotelon ulkopuolella), jolloin sain työnnettyä sitä hieman taaksepäin. Tämän jälkeen laitoin ritilöiden välistä kutistesukkaa tuulettimen ja kotelon väliin ja kiristin ruuvit takaisin kiinni. Tähän loppui kaikki ylimääräinen meteli ja laite toimii nyt kuten pitääkin.
Käytän soitinta elokuvien lisäksi CD-soittimena. Molemmissa käyttötarkoituksissa soitin on toiminut tosi hyvin, eikä ole ollut mitään valittamista (tuuletinongelman ratkaisun jälkeen). Jos en olisi saanut ratkaistua tuuletinongelmaa, olisin lähettänyt soittimen takaisin. Tosin en tiedä olisiko uusi soitinkaan ollut yhtään parempi, kun kyseessä on osin suunnitteluvirhe, missä tuuletin kiinnitetään vajailla ruuveilla. Onneksi ratkesi nyt tällä pienellä diy-kikalla.
