Abstract
A television signal receiver, especially a satellite receiver, operable to receive and process incoming television signals, automatically determines which television signal standard to utilize for its output based on a parameter of the electrical power supply or supplied electricity. Frequency and voltage of the electrical power are measurable parameters that may be used to determine whether the NTSC or PAL (PAL-M or PAL-N) television signal standard is more probable as the local preference and automatically causes the television receiver to code received television signals in that format for output. The present invention utilizes the principle that the local television standard coincides in some manner with the local power line frequency and voltage.
