This article follows the series of articles of the “Living with 4K” topic, and 4K related products and subjects, including 4K content and 4K Blu-ray. Today is about a new 4K player that is just coming to the market, the Nuvola NP-1.

NanoTech Entertainment has confirmed product availability of their Nuvola NP-1 4K player that claims to be compatible with all UHDTVs regardless of brand, as opposed to the proprietary player/TV pairing setup Sony has done with their current 4K media player (FMP-X1) and their UHDTVs/4K Projectors, which limits their 4K media player connectivity to only Sony UHDTVs/4K Projectors.

The other 4K player competiNuvola NP-1 Honored by Storage Visions 2014tor, the $1750 Red Ray 4K player, has been unavailable for over a year after their “reserve your unit” announcement in late 2012 with an original price of $1400+. According to an email I received from the manufacturer last week: “The unit is available on our website with an estimated ship date of 2 – 3 weeks… and we are not distributing units for review at this time”. I still hope they are going to deliver a player as promised and that it will be successful, as well as Odemax, their 4K content provider partner, because the 4K market needs more content and players to play it, not just UHDTVs.

When considering the three 4K player options the Sony 4K player is the only one that is available for purchase on stores, if the Nuvola NP-1 will actually be made available as announced (being announced since May 29, 2013) it appears to be the best deal in price and compatibility, for now, and it was honored recently with a Storage Visions® 2014 Visionary Product Award in the Home Entertainment category.

I am expecting a Nuvola NP-1 review unit to arrive in February 2014 as the manufacturer promised this week, so I can test the quality of the player and the 4K content with a Sony 4K projector. Meanwhile, I thought the readership would appreciate this heads up article that compiles my exchanges with Mr. David R. Foley, Nano Tech’s founder and creator of the NP-1.


Primary Differences between Sony and Nuvola 4K Players

A key difference between the Sony 4K player and the Nuvola 4K player is that the current Sony FMP-X1 4K player has been introduced for downloads of 4K content distributed by Sony, but that may change with a soon to be available Netflix 4K partnership effort announced at CES 2014, and with a streaming prototype media player announced by Sony compatible with the “Video Unlimited 4K” premium 4K distribution service of Sony (more details further below).

How the Nuvola 4K player differs from the Sony is that it has been introduced for primarily streaming 4K content sourced from several providers, and if desired it can also download the 4K content and store it into an externally connected hard drive using its USB 3.0 output, more details further down.

Another difference is price, the Sony 4K player is $699 and the Nuvola 4K player is $299.

Sony FMP-X1 4K player

Another difference is regarding digital audio/video connectivity, the Sony player has two HDMI ports, one HDMI can be used to connect to the 4K display for the 4K video to be delivered undisturbed and the second HDMI can be used to output multichannel digital audio to a home theater audio setup that cannot pass-thru 4K video, in other words, a parallel HDMI connection, one for 4K video, one for multichannel digital audio. If the user has audio equipment that can actually pass-thru 4K video then the parallel HDMI connection would not be necessary.

How the Nuvola player differs is that it has only one HDMI output for the video and audio, and no extra digital audio connection. The implications of this limitation are described further below in the audio section.

Nuvola NP-1 4K Player

Another difference relevant to installations of 4K projectors is that Sony’s 4K player requires the use of a new Sony Xperia tablet to control the player and to download content, which increases the total cost of ownership to about $500 on top of the $699.

Conversely, the Nuvola player has a remote control and does not require a separate tablet. However, Sony’s tablet is elegant and light and can also be used for all the other purposes a regular tablet can be used, although it would have to be returned to the 4K display room when the 4K player has to be controlled.

Regarding 4K content pricing, the Nuvola 4K content providers such as Netflix and Amazon Instant have not yet announced the price of their streamed/downloaded content, on the other hand Sony announced in mid 2013 their player and 4K content service, which is already available and content can be rented for 24 hrs of playback for $7.99 or purchased from $29.99, depending on the movie, TV episode purchases start at $3.99.

As mentioned briefly before, Sony announced at CES 2014 their partnership with Netflix to deliver 4K UltraHD content in the first half of 2014 in all territories where Netflix is available, which implies that a new Sony’s 4K player would be capable of streaming 4K from Netflix in addition to the current 4K player download capabilities. Sony also announced that starting January 2014 more than one hundred and forty 4K movies can be purchased from the Video Unlimited 4K distribution service.

According to Sony’s press release at CES 2014:

Next Generation 4K media player prototype
New media player compatible with Sony's premium 4K distribution service "Video Unlimited 4K." Capable of playing back content at a maximum bit rate of 100 Mbps, it allows customers to enjoy high picture and sound with the stability that content downloads offer.
• In addition to H.264/MPEG-4 AVC (Advanced Video Coding), this new 4K media player incorporates a decoder compatible with the advanced HEVC compression format. This decoder is designed to provide customers with the ability to enjoy 4K/60p content and anticipated new 4K streaming services.
• Also includes a XAVC S decoder. This decoder will allow customers to save 4K video taken using "FDR-AX100" and "FDR-AX1" 4K Handycam®s on the 4K media player's internal HDD and replay these videos on a 4K TV.


Nuvola’s NP-1 player conneBack of Nuvola NP-1 playerctivity limitation of one HDMI complicates the options for the playback of multi-channel digital audio (or for any audio) if the single HDMI output cannot be connected to the display through an A/V receiver/pre-pro that does not accept/pass-thru 4K video, which is the case of most audio equipment in the market that typically cannot be upgraded for 4K pass-thru (it should accept 4K not only output 4K, for upscaling for example).

To accommodate for that limitation the HDMI cable from the 4K player has to be then connected to a) the 4K panel directly and listen to the typically compromised audio quality of its audio sNuvola NP-1 remote controlpeakers/amplification, or b) an HDMI splitter (“one HDMI in/two out”) that simultaneously connects to the audio equipment and to the 4K display for the video (typical if the display is a 4K projector).

Consideration should be given regarding the HDMI splitter current and future compatibility with HDCP 1.0/2.2, and other HDMI 2.0 functionality features such as 60fps 4K, which may entail a future splitter replacement if not upgradeable (more further below). 

Alternatively, there is the commercial Nuvola NP-H1 player available for $699 ($400 above the NP-1) that has additional audio outputs beyond the single HDMI (it has 5-channels analog connectors and a digital optical audio), which, although costly, the NP-H1 would avoid running the risk of compromising the quality of the HDMI 4K video output of the player when the signal goes thru the extra HDMI splitter before reaching the 4K display.

If the NP-1 Nuvola player would have had a separate Digital Coaxial/Optical output in addition to its HDMI it could have output legacy lossy DTS or Dolby Digital 5.1/7.1 discrete digital multi-channel to an A/V system. For lossless DTS Master Audio or Dolby True HD codecs the HDMI output would be needed and the HDMI splitter maybe the only viable solution if the A/V equipment cannot handle 4K.

The player specs are not clear regarding the multichannel audio outputted via HDMI other than the NP-H1 commercial player spec mentioning “5.1” without indicating if that means a) legacy lossy DTS/Dolby Digital 5.1, or b) also lossleBack of Sony 4K Player FMP-X1ss DTS Master Audio/Dolby True HD in 5.1, or c) if the player outputs the soundtrack unaltered as included in the content, or d) the soundtrack is converted to lossy 5.1 regardless if the source is of superior audio quality.

In summary, it would have been ideal if the Nuvola players have two HDMI outputs, as the Sony 4K player (shown on the left) and as several other Blu-ray players have for backward compatibility reasons. Not having them means that the buyer of the player most probably have to spend extra to address the audio connectivity limitation, unless the player is connected directly to an UHDTV panel and the user would not mind its TV audio quality.




The Nuvola player is limited to output 4:2:0 chroma sub-sampling, 8-bit depth, Rec.709 HDTV color space, 24/30 frames per second (for film and video based sources respectively), and is suited with an HDMI 1.4 chip.

In other words, just an HD/Blu-ray type of spec that certainly limits the potential of what 4K content could provide thru the player as per the BT. 2020 Ultra HDTV standard. In fairness, the Sony player shows similar spec limitations with no upgradeability mentioned, and “that” unfortunately may also be the case with the 4K content the public is expected to consume for the near future, including a hopefully soon to be available 4K Blu-ray which spec is in the works and was said will be ready before year end, according to a Samsung statement (and I expect their 4K Blu-ray player prototype by CES 2015 and possibly a finish product available shortly after in 2015).

The manufacturer said the commercial version of the Nuvola NP-1 unit has similar specs, but it is rugged and is designed with software to handle digital signage installations. Other than the extra audio connectivity mentioned above, the company said a consumer would not benefit from spending more ($699) in that commercial unit because it offers the same video quality than the $299 NP-1 unit, and the digital signage capabilities would be useless to regular consumers just looking for 4K playback.

According to the company, the second generation unit (when is available) will be fitted with a 2.0 HDMI chip and a better processor, and is expected to handle 60 fps 4K and better than 8-bit depth, but still limited to output 4:2:0 chroma sub-sampling at 4K 60 fps as per current HDMI 2.0 specs.

The company claimed that the type of HDMI 2.0 chips required for what a 4K player must do are not available yet, although for the purpose of 4K displays the 2.0 chips may be available. Some display manufacturers implemented/upgraded/worked around 1.4 HDMI chips into 4K UHDTVs/projectors and provided some extra “HDMI 2.0 type” of functionality, such as 60 fps for 4K, and HDCP 2.2, without actually installing an HDMI 2.0 chip.

Nano Tech said that they will have to wait possibly until 2Q2014 for the HDMI 2.0 chip suitable to their 4K player to become available. The HDMI 2.0 spec was recently approved in September 2013 and normally takes months before compliant chips become available.


Streaming and Downloading

Although the player is mainly designed as a streamer of 4K content (and of lower resolutions) it can also store a downloaded movie in a compatible storage device connected to its USB 3.0 output, if the content source provides the option/functionality for download, not just streaming.

According to the company, once the content has been stored the user can find the file of the recorded movie in the attached storage device, similarly to a Windows Explorer type of activity, and the movie will be played by the NP-1 player. No details about content organization were provided but I assume there will be no other than folders with files, certainly not as fancy as a Kaleidescape server, and certainly not as pricey either.

In addition to Netflix, Amazon Instant, etc. and other 4K streaming apps that are included in the player's menu, Nano Tech hopes the player will have access to new 4K content providers that are open to the player. Additionally, the company is also implementing their own 4K content service, the bundled UltraFlix™ UHD channel, which will be announced in February of this year, the company said.

Sony’s 4K content service and ODEMAX content partner of the Red Ray 4K player were mentioned in the conversation but they are not included as 4K providers of the Nuvola player.


What’s in the Plans

Although Nano Tech Entertainment has just announced the introduction of their Nuvola NP-1 4K player the company is already working on a second generation of the player for which they are considering and welcoming feedback from the users of the first generation unit released just now.

Along those lines, the company took my request of enhancing the HDMI connectivity limitations for separate audio, which as I said it only has one HDMI output and no coax/optical digital audio outputs, however, no promises were given.

A second HDMI output was quoted as "not a low cost feature" and I suspect it meant “relative to the low player’s price of $299 MSRP”, however, the market has many price-reasonable Blu-ray players and A/V equipment with multiple HDMI outputs, some even supporting 4K.

Nano Tech preferred not to issue any statement estimating the availability of the second generation player, neither to confirm if it would be available even within this year, because, they said, it will take much effort and time to build the second generation unit and test it to make sure it works as expected with the new chips/processor. However, Nano Tech confirmed that they committed their efforts to do so and it will be a matter of time.

There will be an upgrade program for users of 1st generation players (NP-1) to trade them in for a second generation unit when it becomes available. The price of the trade in upgrade is expected to be lower than buying the second generation unit but no details were provided.

It remains to be seen what it would happen to the 4K content stored in the external HDD when switching players, many HD-DVRs loose access to previously recorded content when the attached HDDs are disconnected and reconnected. There will be no upgrades to the 1st generation unit other than the trade-in program. Although it was not said I assume they did not mean that for firmware upgrades thru its internet connection like a Blu-ray player does.

With the eventual upgrade/trade in of the 4K player, an HDMI splitter that was installed for the audio limitations mentioned earlier may also need replacement to be compatible with HDCP 2.2, 60 fps 4K if implemented by the content providers and if the new player still has the same HDMI limitations.
