Media Player based on SMP8653 – Magic Box HDP500

Magic Box HDP500 manufactured by gmini (apparently a Russian company)  is a new media player featuring the 500-Mhz SMP8653 chipset from Sigma Designs. It does not use Android OS yet, and as far I know no company has yet released SMP8653 Android based products. Having said that,  it comes with most of the connectivity you would expect from a decent set-top box: USB connector (device: USB storage,host: laptop/PC connection), Audio/Video Composite ouput, Component (YPbPr)  output, HDMI and optical digital audio output and and Ethernet port.

So that as you can see on the figure above, there is a title safe zone, where everything would be seen in any monitors (Blue Zone) and the gray zone where parts may be seen in some monitors but not others. This mainly depends on the video output used. You won’t have problem with VGA or LVDS monitors,  since the former are able to underscan (to compensate for overscan) automatically, and the latter are generally configured manually. However, with HDMI monitors (unless those which can support underscan) or monitors using composite or component outputs,  you’ll have to handle overscan problem. Overscan will be much more pronounced with older CRT monitors where horizontal and vertical overscan may reach about 10% and 5% respectively, whereas modern displays will usually have up to 5% horizontal and 3% vertical …
