CONNECTED MULTIMEDIA DEPENDENCY MAP
Purpose: identify what one multimedia function needs and what still works.
Use: complete separately for each feature; record exact models and region.
Do not enter passwords, recovery codes or other secrets.
Task and expected result:
Device model / region / firmware / manual URL:
Source -> server or service -> network -> player -> display or audio:
For each connection, document interface / protocol / format / source evidence:
Addressing / discovery / naming requirements:
External dependencies (account, activation, directory, catalog, authorization):
Current provider/model support evidence and date:
Local capability tested / sample file format / observed result:
Service-dependent capability tested / error / observed result:
Supported interruption test / expected / observed / restored configuration:
Router or access-policy documentation consulted:
Original files/settings preserved at (no secrets):
Decision (retain local function / troubleshoot supported service / new player / retire):
Unresolved dependency / next action / owner:
Example only: an external player displaying a local file verifies that path.
Failure of a built-in portal requires its own service/client/network investigation.
