Signal reproducing/recording/transmitting method and apparatus and signal record medium for use with signals featuring a multiple-phase color burst

An apparatus for reproducing digital data from a signal recording medium, comprising:

• means for reading out recording control information from a playback mode control signal area of said signal recording medium, said recording control information being operable to control the playback mode of said record medium;
• means for connecting an additional burst signal to a front side of a standard color burst signal to generate an extended color burst signal;
• and
• means for changing, based on said recording control information, the phase of said additional burst signal and a front portion of said standard color burst signal associated with an analog color video signal generated from said digital data such that the extended color burst signal is modified to include a portion having a changed phase and a portion having an unchanged phase.

A method for reproducing a ciphered signal from a signal record medium, comprising the steps of:
