'''Nintendo Video''' 是一项允许美国/日本/欧洲的3DS用户下载各种任天堂提供的3D视频的服务。Nintendo Video 甚至能在应用自身不再运行时，使用 SpotPass下载视频。

'''Eurosport''' 是一项与 '''Nintendo Video''' 相似的，提供给欧洲用户的服务。

== 互联网接入 ==

它会确认你的3DS所在的国家和地区。不同国家的3DS发起不同的URL请求，它是包含了区域代码(EU/USA/JP)的二级域名, 国家代码根据国家和语言确定。下表包含了已知的国家代码、二级域名与相应文件名。

在下面所有的请求中，COUNTRYCODE应该用你的国家的代码代替，COUNTRYSUBDOMAIN/FILENAME也应据实更换。语言代码应该被替换为所需语言（现在所有可用的语言的大部分的内容是相同的，所以可以使用“1”）。

令人惊讶的是，Nintendo Video使用未加密的HTTP连接来传输视频。按下“连接检查”按钮，Nintendo Video发送一个HTTP请求给''COUNTRYSUBDOMAIN''.est.c.app.nintendowifi.net:

<tt>GET /1/''COUNTRYCODE''/''LANGUAGECODE''/CHECK HTTP/1.1

Host: ''COUNTRYSUBDOMAIN''.est.c.app.nintendowifi.net</tt>

如你所见，没有发送console-specific数据。服务器的响应可能是 403 或者 404 错误代码。403 表示用户区域不匹配 ''COUNTRYCODE'' 和 ''COUNTRYSUBDOMAIN'' (可能根据IP判断)，而 404 表示一切OK.

如果一切正常，3DS进行下载视频。支持Nintendo Video 应用硬解码的似乎只有四个视频，因为它发起以下请求来确认查询到同一台服务器：

<tt>GET /1/''COUNTRYCODE''/''LANGUAGECODE''/''FILENAME''1 HTTP/1.1

Host: ''COUNTRYSUBDOMAIN''.est.c.app.nintendowifi.net</tt>

<tt>GET /1/''COUNTRYCODE''/''LANGUAGECODE''/''FILENAME''2 HTTP/1.1

Host: ''COUNTRYSUBDOMAIN''.est.c.app.nintendowifi.net</tt>

<tt>GET /1/''COUNTRYCODE''/''LANGUAGECODE''/''FILENAME''3 HTTP/1.1

Host: ''COUNTRYSUBDOMAIN''.est.c.app.nintendowifi.net</tt>

<tt>GET /1/''COUNTRYCODE''/''LANGUAGECODE''/''FILENAME''4 HTTP/1.1

Host: ''COUNTRYSUBDOMAIN''.est.c.app.nintendowifi.net</tt>

''FILENAMEi'' seems to return 403 if user's region doesn't match, 404 if ''i''th video doesn't exist and the video itself otherwise. As of 18th of July 2011, only 1st and 2nd videos are available from UK IP addresses.

For Japan region /1/1/0/ESJ_CNF must also present on a server in order to play video files.

These videos can easily be downloaded from any computer with IP address that matches country specified by ''COUNTRYCODE'', ''COUNTRYSUBDOMAIN'' and ''LANGUAGECODE'' using wget without any special settings. Videos are region-locked.

== SD storage ==
Downloaded videos are stored in the SD card [[Extdata]], from the decrypted [[SpotPass]] content payload. Country info is presumably stored in this metadata, region-lock is handled by the BOSS module via the programID in the [[SpotPass#Payload Content Header|payload header]]. At the end of the video file is a JPEG, which contains the video thumbnail, and various metadata in the EXIF including the URL associated with the video. The text shown on the web browser button is also stored in the EXIF.

All of these fields are big-endian?

== File format ==

File format used for storing videos is not yet known either. Both videos that were available at 18th of July 2011 contained string "boss" in the first four bytes, which leads me to believe this is a [http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files "magic number"] used to identify this type of file.
This header and the crypto used for the payload following it, is the [[SpotPass]] content container format.(See the SpotPass page for info on the container format) See the above SD storage section for info on the cleartext payload.

The video codec used is unknown.(But going by the manual it should be Mobiclip in some form) Region info is stored in the decrypted SpotPass crypto layer, see above SD section.

== Server spoofing ==

In case you want to try messing with Nintendo Video, here's a description of what I did:

# Set up a DNS server using bind9, which returned my IP as the IP for pubeu-p.est.c.app.nintendowifi.net [http://pastie.org/2230422 (bind config)].
## Don't forget to replace MY_IP in config with your IP address, but '''don't''' replace the IP of conntest.nintendowifi.net service
# Set up an HTTP server using nginx and put ESP_MD1, ESP_MD2 (which I have downloaded from Nintendo's servers earlier, see above) in my /var/www/1/110/1/ folder.
# Configured my 3DS to use my DNS server as both primary and secondary DNS server.
# ???
# PROFIT!
