ABSTRACT:
A technique for delivering analog video over fiber-to-the-home (FTTH) networks addresses a fundamental problem of the standard signal format, i.e., power budget constraint, by increasing the usable optical signal efficiency. In particular, a technique is provided for transmitting an efficient modified analog video which is compatible with existing receivers. More specifically, the synchronization portion of a standard NTSC video signal is reduced in amplitude during transmission, producing an appreciable increase in the allowable optical modulation index (OMI).
