Q: streaming is not working on Iphone 5

Hello bertpols,

Thank you for the details of the issue you are experiencing with AirPlay.  Accessing AirPlay in iOS 7 is a little different than in the previous iOS.  You can now access AirPlay through the Control Center when you're in any app:

• Display the AirPlay controls. Swipe up from the bottom edge of the screen to open Control Center, then tap .
• Stream content. Tap , then choose the device you want to stream to.

If you are not seeing the AirPlay icon in Control Center, I recommend reviewing the steps in the section titled "If the AirPlay icon doesn't appear" in the following article to isolate and troubleshoot the issue (you can skip any steps that refer to a Mac or Apple TV since you are experiencing this with your iPhone):
