Patent number: 9554180Abstract: A system includes a converter to receive a receiving a satellite signal at first transport frequencies and to convert the satellite signal to second transport frequencies and a processor. The processor removes a radio frequency portion from the satellite signal without altering a sequence of media contents of a moving picture experts group portion of the satellite signal and without altering a quality of the media contents of the moving picture experts group portion. The processor determines whether the media contents include an error and corrects the error in the moving picture experts group portion with error correction data of the satellite signal. The processor encrypts the media contents to produce an encrypted digital moving picture experts group transport stream signal. The processor also sends the encrypted digital moving picture experts group transport stream signal to a modulator.Type: GrantFiled: April 26, 2013Date of Patent: January 24, 2017Assignee: AT&T Intellectual Property I, L.P.Inventors: Brad Allen Medford, Ahmad Ansari, Dinesh Nadarajah
