you would be surprised. For how many languages do you plan to localize? How many date-formats for the built-in clock? What about a virtual keyboards and input methods? do you support EPG? hbbtv? a rudimentary browser and everything that goes along with that? So you want to support netflix, are you ready to be certified by them, including system security and are you ready to give up everything lpglv3/gplv2 because of the anti tivoization clause? Will you support multi-tasking? wayland, x11 or something entirely different? You will want to make it usable from some kind of remote. Do you have QA to test all of that and are they knowledgeable about all the internationalization issues? You will need a specialist on tuning and decoding of ATSC, DVB, hdmi inputs, upsampling (motion interpolation) to 100hz, 120hz and above. color enhancements, dynamic brightness, the list goes on and on.
