  5. E-mail – Killer Application?! T.Sharon-A.Frank

  6. Multimedia Mail  T.Sharon-A.Frank

  7. Multimedia Mail Challenges • Incorporate Generators/Viewers • Massive Storage Space • Different Standards – Interoperability • different media formats • different platforms • different protocols T.Sharon-A.Frank

  8. MIME Overview • MIME (Multipurpose Internet Mail Extension): • Unlimited Text Line Length or Overall Length • Character Sets other than ASCII • Binary or Application Specific Files • Multiple Objects in a Single Message • Images, Audio, Video Attachments T.Sharon-A.Frank

  9. MIME Types • Need to identify the type of media data in a data stream in a platform-independent way. • Originally designed to allow inclusion of data other than text in email, adopted by HTTP. • Content-type: type/subtype. • Types include text, image, audio, video, application, subtypes define specific formats. • e.g. text/html, image/gif

  10. Text example subtypes: plain, html Image example subtypes: jpeg, gif Audio example subtypes: basic (8-bit mu-law encoded), 32kadpcm (32 kbps coding) Video example subtypes: mpeg, quicktime Application other data that must be processed by reader before “viewable” example subtypes: msword, octet-stream Example MIME Types T.Sharon-A.Frank

  11. Six top-level MIME types and some common subtypes T.Sharon-A.Frank

  12. step: protocol for exchanging email messages RFC 822: standard for text message format: header lines, e.g., To: From: Subject: differentfrom SMTP commands! body the “message”, ASCII characters only line containing only `.’ Mail message format header blank line body . T.Sharon-A.Frank

  13. MIME: multimedia mail extensions, RFC 2045, 2056 Additional lines in message header declare MIME content type. From: alice@crepes.fr To: bob@hamburger.edu Subject: Picture of yummy crepe. MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Type: image/jpeg base64 encoded data ..... ......................... ......base64 encoded data . Message format: multimedia extensions MIME version method used to encode data multimedia data type, subtype, parameter declaration encoded data T.Sharon-A.Frank

  14. Mail Types • Compound Mail • Includes text, graphics and/or images • All attachments are printable • Multimedia Mail • Explicit Inclusion – all media included • Implicit Inclusion – only links to media T.Sharon-A.Frank
