Technical Details
what runs on :6419SVDRP runs over TCP, normally on port 6419, and uses a line-oriented command/response exchange. The server begins with a 220 greeting; commands and responses are terminated by CRLF, with three-digit response codes and hyphen-marked continuation lines for multiline replies. Commands can query or change recorder state, including channels, timers, and recordings. The protocol is not encrypted; VDR deployments commonly restrict permitted client addresses through svdrphosts.conf.

security overview
SVDRP can expose control over recordings, timers, and other recorder functions. It has no transport encryption, and deployments commonly rely on source-address restrictions rather than strong client authentication, so do not expose it directly to the internet; restrict it to trusted hosts or a VPN.
