The unit I purchased because of the possible Internet functions. Here is my report, about ways to program or to stream TV programs and recordings the unit via the Internet, Android and iPad / Watch on iPad or Android. I am for several years satisfied users from TechniSat s1. The quality of the picture "upscaling" is really neat and there is also a network interface, but only when S1 and not the S1 + (HD). In addition, the design is quite appealing. What I lacked was a dual tuner (record while watching another program) From traveling to schedule recordings or even look. When unpacking, I was a little disappointed. The case is not very appealing. But it can be also very good at hiding, ordered by an infrared extension and "hiding" the unit in the cabinet. That's great and is not the S1. The establishment of ufs913 was pretty easy. I have assigned a fixed IP address and could access via Firefox immediately and program channels for recording. The EPG is quite clear - perhaps a little better than the S1. What bugged the S1, were the long start and switching. These are much faster when ufs913. The image quality of 913 and s1 are approximately identical. Both have a very decent HD image and a very good image in the SD programs. An external connected Samsung 1TB disk and also works flawlessly. The launch of the system will take about 10-15 seconds, which is not very fast, but much better than the S1. To CI / CI + I can say nothing, is not used by me. Home network tested in great detail - here the ufs913 developed its strengths Android: UFScontrol installed and set IP and even the remote control work via smartphone (LG-P880 Android 4:03) Have sought in vain for a way to watch movies directly. After an intensive search, I found the app BubbleUPnP that even the 913 detects and displays the recorded files. This only works with the additionally installed VLC Player. When s1 there is no remote control or access via UPnP or DLNA. As scores of 913 powerful before S1. I have connected a Samsung TV that is also network-compatible and can be controlled via the Apps SamyGo or Samsung Remote. IPad: The iPad there is a program UFScontrol HD with the streaming of recorded movies, remote control and programming of recordings is quite comfortable possible. -that PiP (picture-in-picture) in HDTV does not really work, one sees only still images, according to program changes may also only a black box. In SD programs PiP goes but super. When streaming of live TV programs you have to note that there is only switched, otherwise the whole thing will not work. Having read various reports, I downloaded and installed the latest 2.0 operating software firstonce via USB from Kathrein. The unit does so quite stable. So far, no crashes. Forgot my complete house automation (hexamis.com IPcams and XS1), as would be complete without the control of the media. Overall, I am satisfied with the ufs913 and enthusiastic. By releasing via DynDns (no-ip.com Fritzbox 7390) I can control everything on the go. Only the apps sometimes jolt a bit, but generally work pretty well. Conclusion: I regret the purchase in any way and would again buy the device at any time. Excellent price / performance ratio very pleased overall.
