Abstract: A system for expanding access to PSTN based telephone lines (landlines). The system can achieve landline reliability and superior voice quality similar to Skype or VoIP at computing devices such as desktops, laptops, smartphones (e.g., Blackberries®, iPhones®, PDAs), cell/mobile phones, tablets, and the like, by allowing landline calls to and from such computing devices. The PSTN landline connection can be used for placing or receiving calls through such computing devices, and can be made available at alternate external fixed and mobile locations, i.e., at locations other than a standard wired or wireless telephone connected to a wall jack. A LandLink CPE is provided for connecting at least one computing device to the Public Switched Telephone Network (PSTN) for making calls.

Abstract: A laser video disk master is operated at 2.times. speed for duplicating video information to be recorded in VHS format. Two last disk video players are modified to operate in synchronism in order to multiplex from one to the other in duplicating video programs of length equal to the two recorded disks. The 2.times. frequency NTSC format video output signal is then demodulated, drop out detection is performed, and the digitally-encoded stereo audio information is separated, error corrected, and converted by digital to analog (D/A) conversion to left and right channels of stereo analog information. The left and right channels of audio information are presented simultaneously to an FM modulator for presentation to rotating video heads and to a 2.times. Dolby processor for presentation to linear heads. The demodulated 2.times. video information is converted to digital information by an analog to digital (A/D) converter and then time-base corrected and drop out compensated.
