Power regulator/UPS and AV distributor circuit for Raspberry Pi

I need a circuit designed for a Raspberry Pi that contains the following:

Voltage regulator receiving +12V DC input and outputs +5V DC. The +5V DC will power a Raspberry Pi and should contain a UPS circuit using either battery power or capacitors (preferred). Upon +12V DC loss, the battery should power the Raspberry Pi for ~5 minutes and a signal should be sent to the Raspberry Pi over either an SPI or I2C interface to shutdown the Raspberry Pi.

Within the same circuit, I'd also like to power an AV amplifier/distributor. The circuit should take one RCA input (Video, Left Audio, Right Audio) and have 4 outputs.
