  • Patent number: 9338516
    Abstract: In a method for transferring data via a digital television (DTV) network and a mobile communication network using an electronic device, the method receives a DTV signal via the DTV network and detects a decode error rate (DER) of the DTV signal at a first frequency. The method further detects the DER of the DTV signal at a second frequency and detects an average signal strength of the mobile communication network when the DER is continuously greater than a first threshold value. The method builds an electronic connection between the electronic device and a multimedia server via the mobile communication network and receives multimedia data from the multimedia server when the DER is continuously greater than a second threshold value and when the average signal strength is continuously greater than a third threshold value.
