Streaming 4K content with high bitrate


bfds89

Question

Hi. 

I've got a LG OLED C7 with smart IP TV app. I'm having trouble watching 4k movies with high bitrates ( some movies have bitrates higher than 80mpbs). I already connected the TV with wifi AC (5Ghz) instead of ethernet connection (which has only 100mbps port).  

My internet connection has a speed of 200mbps (tested on tv browser).  Nevertheless I'm struggling playing those 4k high bitrate movies. Every few minutes it buffers.

What can be the problem? The TV plays high bitrate movies from USB or bluray and the internet speed should be enough for those bitrates.

 Is it possible to install a gigabit ethernet port in the pcmcia port?

Thanks for your help.

The simple answer is no, but as long as the bitrates do not top 100mbps then the standard network card would do fine.  So you could at least do some testing with a cable to see if the issue is with the WiFi itself or something else.  That said the AC wireless card in the TV should be more than equal to the task you are asking of it. 

What source are you trying to stream from? 
Are you streaming directly from the modem/router to the TV?
Is anyone else in the house using the network when the buffering occurs?

Hi,

I'm using SMART IPTV app with an iptv list.

The service provider already guaranteed that the server is more than capable to share media through internet.

I also tested playing movies through usb pen with success. Initially I was connected  with ethernet port, but experiencing buffering issues, so I decided to connect with wireless so I could achieve more speed (around 200mbps).

Basically I'm trying to stream High bitrate 4K movies (Bluray quality) through internet with no success (buffering from time to time), but I already guaranteed that the problem is not with the server and also by connecting with a speed that is superior than the bitrate of the movies.  Also the 5GHz band is used exclusively by the TV with no interference from the neighborhood, since they use only the 2.4GHz band.

If I could use a PCMCIA card with gigabit connection it would be great.

So you have experienced buffering on both wired and wireless connections?

Just because the content provider's server is capable of streaming 4K and you connection can hit a peak that should be good enough, there are a whole lot of things between them and you that can cause issues.  

I was not thinking of interference with the 5GHz WiFi, but more people using the local/house network.  For instance Windows does have not bandwidth restrictions so if someone downloaded a file while you were streaming Windows will potentially hog all the available bandwidth.  Some modem/routers offer bandwidth quotas for devices, this would help prevent such a problem.  Another things to think about is whether the modem/router has the latest firmware installed.

If you know someone with a suitable Netflix account (or any other service with 4K content) and would let you use their details you could stream a 4K video with them to see if you had the same issue.

Did you test the same stream on a computer with gigabit ethernet?

Well yeah. but I guess my laptot ASUS K550JX with a i74750HQ and a nvidia geforce gtx950m is not enough to run movies using HEVC codec with high bitrate, the movies displays lots of artifacts when watching on PC.

Yes, with wired connection I though it was of the bottleneck of 100mbps port so I changed to Wifi AC.

The TV is the only equipment using the 5GHz network in my household.

I have a Netflix account and it works flawless, but Netflix doesn't stream high bitrate movies,  I think the bitrate of netlflix is around 20-25mbps so this work well.

I remind you that the content I'm trying to stream has bluray quality with very high bitrates.

Hi,

Yes I get that you are trying to stream hit bitrate streams, but no I did not know about the Netflix bitrate.  

When it comes to the WiFi I am not suggesting that something is interfering with the signal, more that is there anything else on the 2.4GHz/wired networks that are using bandwidth?  The traffic is going to pass through the same modem router at the end of the day.

Do you have access to an alternative modem/router for testing?

Hi

as i assume you are trying to stream the high bit rate video from a remote server, can i know your internet speed?

do you have any idea about the video bit rate of the 4k video

secondly, the pcmcia card cannot use for extending system capabilities. Its just a card slot to add subscription cards for satallite channels ( scrambled channels) also part of some regulatory laws.

4K Blu-Ray maxes out at 128 Mbit/s. I 99.99% guarantee your IPTV service is not outputting at anything close to that bandwidth. If they *are* sharing movies at anything close to that bitrate I also 99.99% guarantee it is pirated content. Don't try to have your cake and eat it too; just buy a 4K Blu-Ray player, invest in some discs, pay a legitimate price for content and enjoy top quality without buffering.

      I am creating a streaming application, where user can access a list of mkv files from my server, Mkv is not supported in web browsers and it is not loading properly within my webOS web app.
      I cannot modify my files to another video format.
      Is there a native player for LG WebOS that I can embed into my web application ?
      Is there any video player with web sdk to play mkv on a smart tv.
      Ps: my videos are working well on chrome, as for Firefox or Safari, it tells me that the format is not supported.

      The problem that my QNAP NAS Mediaserver disappears from the WebOS Home screen and from the Home dashboard happens irregularly and unpredictably almost daily. The only way to get it back is to reset WebOS to its initial (factory) settings. After I do that, it always reappears on the Home scree/Home dashboard. I have no idea why this happens, it even happens after I watch an hour of movie content from the NAS and then want to browse through the files on the NAS: it suddenly is not accessible anymore. I tried to tweak (a lot of) the NAS settings but nothing helps.  
      My NAS has a fixed IP in my home LAN. Is it possible to connect to it with the IP address? 
      Any other suggestions how to remedy this tedious problem are welcome!

      In the file attached is a photo of the Home dashboard with the Mediaserver present.

      When trying to use apps that need an internet connection I get an error (-106) saying that there is no connection. When I go to settings -> Network -> Wifi it says that wifi is turned off and I need to turn it on to see available networks. Well there's no switch or option to turn wifi on. I've had it connected to wifi before. Also sometimes it disconnects and then I have to go back in and tell it to connect again. This is the first time its said the wifi was off.
      I did a google search and the results that came up were for WebOs 1.0, even though it was written in 2017, and I have WebOs 3.0. It said hold the settings button until a box appears in the top right of the screen and input 0 0 0 0 then adjust the baud rate. First no box shows up on the 3.0 and two its not the baud rate I'm trying to adjust.
      I tried calling customer support to get to technical support. The automated system is garbage by the way. Then I found out they are only open Monday through Friday as if customers never have a problem on the weekend.
      This is my third stop looking for an answer. This problem is causing my dislike of LG products to grow even more. So if anyone has had this problem and figured it out I would greatly appreciate your help and thanks in advance for your time and help.

      Hello,
      Is there any way of installing an usb gigabit network adapter on a webos smart TV?  The builtin wired adapter is only 100mbps (on a 2000$+ TV, shame  on you LG!!!)  while the wifi (N) is very poor, with the router at 1m from TV it only gets half the bandwidth of the wired network. Anyway the wired network  maxes out near 100mbps but I need more bandwidth as I have 4k video content with bitrates grater than 100mbps which I cannot stream without stuttering to TV through XPLAY/PLEX. 
      Kind regards,

      I have recently shifted from UAE to India. I have 55" LG 3D smart TV model no. 55UB8301. My problem is 1. I can not change country from UAE to India in settings -Country option because India is not available in the list.
      2. I can not download any app which are normally available in Indian smart TVs like Hotstar/Sonyliv/Amazon prime etc.
      3. In screen mirroring option using my Android phone, I can play any video stream from mobile to smart TV BUT only Amazon prime videos are not played. 
      Can anyone help me for above issues...?
