I recently upgraded to a NVidia Android Shield. Everything seemed “ducky” for awhile but now I am experiencing a spinning buffering effect every once in awhile. All of my stations show up strong with the exception of one that never did show up strong. I use an indoor log-periodic dipole array Turk antenna with amplifier. Is this usually a reception problem or other? I could try to elevate the antenna or aim it slightly to see if that helps. Any thoughts.
You didn’t say anything about your network between tablo and shield. This can be a big factor.
Hard wired. Thank you.
I’ve had some heat problems with my Tablo. I find I used it more as they published software updates and improved its performance and functionality. This left me in a situation trying to figure out what changed about signal, network performance, etc. I then realized that the unit itself kept getting very hot so I have been experimenting with various positions and placement attempting to adapt it to allow for the best dissipation of heat. I think I’m going to order one of the chill mats for laptops and place it on that to help cool it.
This might not be the same situation you are in but I figured it was possible with how you described the behavior at first and getting something new etc. might be a contributing factor to different behavior.
Generally heat affects antenna reception (RF signal transmission). In fact the “noise” in an electrical signal is generated in part by heat. I’ve never thought about the influence of heat on a TV tuner but it may affect a tuner’s performance inside an overheated box by increasing its noise floor (the measure of a tuner to recognize a valid signal). Heat might distort reception and signal processing causing the DVR to become erratic. Just speculation…
I put four plastic legs (one inch tall) under my Tablo to allow air to flow under it.
Where I was heading with the heat aspect was that the hotter a processor the slower the processor performs. The Tablo definitely utilizes a processor of some kind and if it is hot enough, will degrade performance of transcoding the signal to a digital stream suitable for ingesting by roku, web app, shield, apple tv etc. But this is all speculation based upon circumstance and observation of my behavior as it relates to new toys and improved software.
I think you’re right because I had a problem with my Samsung DLP TV a few years ago. I had to replace a chip inside of it because the manufacturer had put in a faulty heat sink thus causing the digital light processing chip to overheat and degrade over time.
