At risk of making it too 'modern' you could replace them with 82V Zener diodes but do not bypass them completely. They are used as voltage regulators but be careful because they do change characteristics after a lot of use.

The (only) thing that would make any particular byte value a special symbol is how it is interpreted by the applications that send and receive it. So, use something easy to detect, 0 or ff, and you will have to also make sure that this value *is not* sent by your app in any of the multimedia data.
This can be done either by encoding the data so
