Video Decode Quality with HQV 2.0

Posted by Martina Birk on Tuesday, August 20, 2024

One of the bugs in the currently available firmware for the Boxee Box is the constant buffering and stuttering of Blu-Ray M2TS files, even over USB. Unfortunately, the HQV 2.0 benchmark we have is a set of M2TS files from a Blu-Ray ISO. I had to put up with constant interruptions in the benchmarking videos, and as such I wasn't very comfortable tabulating the results. I tried repeating playback of each stream more than 3 times each to ensure that I had a fair idea of how the playback quality turned out.

The Boxee Box appears to fare a little bit better than the average WDTV type streamer even with the unreliable firmware. Do note that some of the tests simply make no sense for the Boxee Box because the knobs to activate and test out the features just don't exist (as Boxee probably doesn't want to befuddle the average user with some arcane menu options).

That said, one of the disappointing aspects revealed in the above benchmark is the complete lack of cadence detection. Hopefully, the end user doesn't want to spend too much time watching interlaced videos at non-native video refresh rates. Other than that, we wouldn't fault Boxee too much for not scoring higher in this benchmark.
