PROBLEM TO BE SOLVED: To provide a digital signal recorder that economically generates time stamp information by using an analog video signal simultaneously outputted from a set top box STB outputting stream data. SOLUTION: An analog video signal outputted from an STB 1 is given to a SYNC separator 11 of a D-VHS recorder 10, which fetches a synchronizing signal. This synchronizing signal is fed to a phase locked loop 13, which generates a 27 MHz clock. The 27 MHz clock is given via a changeover switch 17 to a time stamp generator 19, which generates a time stamp and gives it to a D-VHS formatter 21.
