# [[HTML Media]]

## 🎯 한 줄 통찰 (One-line insight)
Web multimedia is anything you can see or hear — images, music, sound, video, animations — but only a small set of formats (MP4/WebM/Ogg for video, MP3/WAV/Ogg for audio) is actually supported by the HTML standard across browsers. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Multimedia is broad** — it can be almost anything you can hear or see: images, music, sound, videos, records, films, animations, and more. [S1]
- **Browsers evolved** — early web browsers supported only text in a single font and color; modern browsers support colors, fonts, images, and multimedia. [S1]
- **Formats matter** — multimedia files have their own formats and extensions; only some are supported by HTML. [S1]
- **HTML-supported video** — only MP4, WebM, and Ogg video are supported by the HTML standard. [S1]
- **HTML-supported audio** — only MP3, WAV, and Ogg audio are supported by the HTML standard. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Format-by-extension pattern** — a media file's container/codec is identified by its extension (.mp4, .webm, .ogg, .mp3, .wav). [S1]
- **HTML-standard subset pattern** — many formats exist, but author for the HTML-supported subset (MP4/WebM/Ogg, MP3/WAV/Ogg) for cross-browser playback. [S1]
- **Recommended-format pattern** — MP4 is supported by all browsers and recommended by YouTube; MP3 is supported by all browsers for audio. [S1]

## 📖 세부 내용 (Details)
**What is multimedia?** Multimedia on the web is sound, music, videos, movies, and animations. Multimedia comes in many different formats — almost anything you can hear or see: images, music, sound, videos, records, films, animations, and more. [S1]

**Browser support** — web pages often contain multimedia elements of different types and formats. Early web browsers had support for only text, limited to a single font in a single color. Later browsers added support for colors, fonts, images, and multimedia. [S1]

**Common video formats** — multimedia elements (like audio or video) are stored in media files; the most common way to discover the type is to look at the file extension: [S1]

| Format | File | Description |
|---|---|---|
| MPEG | .mpg, .mpeg | One of the first popular video formats for the web; no longer supported in HTML |
| AVI | .avi | Developed by Microsoft; commonly used in video cameras and TV hardware; plays well on Windows but not in web browsers |
| WMV | .wmv | Windows Media Video, developed by Microsoft; plays well on Windows but not in web browsers |
| QuickTime | .mov | Developed by Apple; plays well on Apple computers but not in web browsers |
| RealVideo | .rm, .ram | Developed by Real Media for video streaming with low bandwidths; does not play in web browsers |
| Flash | .swf, .flv | Developed by Macromedia, often requires an extra plug-in; no longer supported |
| Ogg | .ogg | Theora Ogg, supported by HTML |
| WebM | .webm | Developed by Mozilla, Opera, Adobe, and Google; supported by HTML |
| MP4 | .mp4 | Designed to store video and audio; commonly used in video cameras and TV hardware; supported by all browsers and recommended by YouTube |

**Note:** Only MP4, WebM, and Ogg video are supported by the HTML standard. [S1]

**Common audio formats** — [S1]

| Format | File | Description |
|---|---|---|
| MIDI | .mid, .midi | Format for electronic music devices; very small files; not supported directly by web browsers |
| RealAudio | .rm, .ram | Developed by Real Media for audio streaming at low bandwidths; does not play in web browsers |
| WMA | .wma | Windows Media Audio; plays well on Windows but not in web browsers |
| AAC | .aac | Advanced Audio Coding, developed by Apple as the default format for iTunes; does not play in web browsers |
| WAV | .wav | Developed by IBM and Microsoft; plays well on Windows, Macintosh, and Linux; supported by HTML |
| Ogg | .ogg | Developed by the Xiph.Org Foundation; supported by HTML |
| MP3 | .mp3 | The most popular format for music players; combines good compression with high quality; supported by all browsers |
| MP4 | .mp4 | A video format, but can also be used for audio; supported by all browsers |

**Note:** Only MP3, WAV, and Ogg audio are supported by the HTML standard. [S1]

## 🛠️ 적용 사례 (Applied in summary)
The format tables above are the practical takeaway: when adding `<video>` or `<audio>` to a page, author for the HTML-supported subset (MP4/WebM/Ogg video; MP3/WAV/Ogg audio), favoring MP4 and MP3 for the widest browser coverage. No external project/commit applications found in the source.

## 💻 코드 패턴 (Code patterns)
This overview page does not present a specific code example; the supported formats are applied via the `<video>` and `<audio>` elements documented in [[HTML Video]] and [[HTML Audio]]. The actionable pattern is the HTML-supported format subset:
- Video: MP4 (`video/mp4`), WebM (`video/webm`), Ogg (`video/ogg`)
- Audio: MP3 (`audio/mpeg`), WAV (`audio/wav`), Ogg (`audio/ogg`)

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
No contradictions found in the source. The historical note is that several once-common formats (MPEG, Flash .swf/.flv, RealMedia) are "no longer supported" in browsers — reflecting the move to the small, royalty-conscious HTML-native format set. [S1]
