ABSTRACT:
An apparatus for converting a signal from a first analog format to a second analog format. The apparatus has an input port, a first converter, filters, first mixers, second converters, and an output port. The input port is configured to receive the signal. The signal has the first analog format. In an embodiment, the first analog format complies with the SCTE 40 2003 technical standard. In an embodiment, the second analog format is a conventional analog format. The first converter is coupled to the port and is configured to convert the signal to a first digital format. The filters are coupled to the first converter and configured to isolate a first channel of the signal from a second channel of the signal. The first mixers are coupled to the filters and configured to expand the first channel and the second channel to a second digital format. The second converters are coupled to the first mixers and configured to convert the first channel and the second channel to the second analog format. The output port is coupled to the second converters and configured to produce the signal having the second analog format.
