During step 514, the converter of the powerline adapter 504 may decode, convert or format the powerline signal to be outputted through any number of connectors or ports of the powerline adapter 504 based on the user's selection of the output format or available technology on the television. For example, the powerline adapter 504 may include an HDMI port for communicating the formatted signal to the television. In another example, the powerline signal may be conveyed to the television as a reformatted powerline signal that may be extracted from a power connection of the television for display. The powerline adapter 504 may include any number of connectors, cords or other interface elements.
Next, the powerline adapter 504 communicates the formatted signal to the television (step 516). The formatted signal may be communicated through a port or connector of the powerline adapter 504. For example, audio and video interfaces may be externally connected to the powerline adapter 504 and the television. A short range radio frequency or infrared signal may also transmit the formatted signal to the television.
