Sony TRV65E (Hi-8) input enable

The UK PAL model of the Sony CCD-TRV65E camcorder may be enabled for A-V input, thus permitting it's use as a high-band mastering recorder . This could be of benefit for making master recordings of events on location, where the size, weight, or power requirements of an S-VHS or D-VHS master recorder preclude the use of such equipment. The procedure is as follows:
  • Change 00:01 from 00 to 01 <STORE> (enable memory write)
  • Change 0D:14 from 64 to 66 <STORE> (enable A-V in)
  • Change 0D:21 from 00 to 02 <STORE> (checksum compensation)
  • Change 00:01 from 01 to 00 <STORE> (disable memory write)

This procedure does not involve monitoring or changing the checksum. Instead, a compensating value is set into the otherwise unused location 0D:21 in order to compensate for the functional change introduced into 0D:14.

It is possible that the procedure may also work on NTSC models, but this has not been tested. On the other hand, it is possible that NTSC models may have the facility as standard.

The printout (dump) of the memory values held in page 0D of an input enabled TRV65E is as follows:
