# Update entry 49 (`com.museblossom.contentsdefence.1`) — add `audio` and `video`

## What changes

Only `decodedMediaTypes` changes, from `["image"]` to `["audio", "image", "video"]`.

Per the contribution guidelines, `identifier`, `alg` and `type` are unchanged.

```diff
   "identifier": 49,
   "alg": "com.museblossom.contentsdefence.1",
   "type": "watermark",
-  "decodedMediaTypes": ["image"],
+  "decodedMediaTypes": ["audio", "image", "video"],
```

## Why

Contents Defence (MuseBlossom Co., Ltd.) now embeds and extracts the same invisible
watermark in **audio** and **video** assets, not only still images. The algorithm and
its identifier are unchanged — the entry's media-type scope simply no longer reflects
what the algorithm covers.

The watermark serves the same purpose in all three media families: recovering the
associated C2PA manifest from a Manifest Repository when embedded metadata has been
stripped (for example after re-encoding on social platforms).

## Checklist against the selection rules

- Conforms to the schema — `decodedMediaTypes` values are from the documented enum
  (`application`, `audio`, `image`, `model`, `text`, `video`).
- `identifier`, `alg`, `type` unchanged, as required for updates.
- Submitted by an individual affiliated with MuseBlossom Co., Ltd., which owns the
  algorithm.
- `informationalUrl` (https://museblossom.com/about) resolves.
- The algorithm supports both embedding and extraction of the soft binding identifier
  for manifest recovery.
