[5] [CODE[video/[VAR[*]]]] [[媒体型]]は、[[動画]]形式を識別します。
純粋な動画(謎)のみならず、[[アニメーション]]の類もここに含まれます。
;; [8] 利用者の指示に従い動作する[[対話的]]内容や様々な内容を組み合わせる複合的な形式は
[CODE[[[application/*]]]] に分類されるのが普通です。
;; [9] [[アニメーション]]は [CODE(MIME)@en[[[image/*]]]] を使う場合もあります。

[FIGCAPTION[
[7] RFC 2046 4.4. Video Media Type
]FIGCAPTION]
>A media type of "video" indicates that the body contains a
time-varying-picture image, possibly with color and coordinated sound.
The term 'video' is used in its most generic sense, rather than with
reference to any particular technology or format, and is not meant to
preclude subtypes such as animated drawings encoded compactly. The
subtype "mpeg" refers to video coded according to the MPEG standard [MPEG].
[CODE(MIME)[video]] の媒体型は、本体が、絵が時を追って変わる,
色がついていたり音がついていたりすることもある画像で構成されることを示します。
用語[DFN[[RUBYB[動画] [video]]]]は、
特定の技術や形式を指すというよりもその最も普通の意味で使うこととし、
[RUBY[軽少] [コンパクト]]に符号化した[RUBYB[動く図形] [animated drawing]]を排除することを意味するものではありません。
亜型 [CODE(MIME)[mpeg]] は、 [[MPEG]]
規格により符号化された動画を指します。
>Note that although in general this document strongly discourages the
mixing of multiple media in a single body, it is recognized that many
so-called video formats include a representation for synchronized
audio, and this is explicitly permitted for subtypes of "video".
なお、一般にこの文書は複数の媒体を単一の本体に混合することを強く非推奨としていますが、いわゆる動画形式の多くは同期音声の表現を含んでいると思われるので、
亜型 [CODE(MIME)[video]] に関しては陽にこれを認めます。
>Unrecognized subtypes of "video" should at a minumum be treated as
"application/octet-stream". Implementations may optionally elect to
pass subtypes of "video" that they do not specifically recognize to a
robust general-purpose video display application, if such an
application is available.
認識出来ない [CODE(MIME)[video]] の亜型は、少なくても
[CODE(MIME)[[[application/octet-stream]]]]
として扱うべきです。実装者は具体的に認識出来ない
[CODE(MIME)[audio]] の亜型を頑強な一般目的動画演奏応用があればそいつに渡すことを任意で選んでも構いません。

*メモ
[4] 静止画なら [[image/*]] 媒体型, 音声のみなら [[audio/*]] 媒体型をどうぞ。立体図形なら [[model/*]] 媒体型, その他高度な機能が含まれるなら [[application/*]] 媒体型かもしれません。
