1. Project Description

Overview

There are many different types of digital media formats that are commonly used by artists and creative practitioners for a variety of outcomes. This assessment task asks you to create a glossary of digital media formats that demonstrate your understanding of which types of formats are used for different purposes & the pros & cons of each type.

What is a MIME type?

Multipurpose Internet Mail Extensions (MIME) is an Internet standard that extends the format of email to support:

  • Text in character sets other than ASCII
  • Non-text attachments
  • Message bodies with multiple parts
  • Header information in non-ASCII character sets

MIME's use, however, has grown beyond describing the content of email and now is often used to describe content type in general including for the web and as a storage for rich content in open source and commercial software products. We often use MIME type to describe a format such as JPG for the JPEG image format, MP3 for the MPEG 3 audio format or MP4 for the MPEG 4 video format.

To see an example of a list of MIME types recognised by various software and server applications, take a look at this URL:

http://svn.apache.org/viewvc/httpd/httpd/branches/2.2.x/docs/conf/mime.types?view=annotate

Information for this assessment task is freely available via the Internet, and very easy to find with simple searches.

The standard types of formats & MIME types you can cover come under the following categories (you only need to select 4 file formats per category - where more than 4 are listed)

Image: JPEG; PNG; GIF; TIFF; PSD; AI; BMP; TGA

Audio: MP3; AIFF; WAV; OGG; AU; MIDI

Video/Multimedia: MP4; MOV; DV; AVI; FLV; SWF; VRML

3D - some common 3D interchange formats: 3DS; ASE; OBJ; BLEND; PLY; LWO; LWS; FBX; 3D

Document: TXT; PDF; RTF; DOCX; ODT

Hypertext / Hypermedia / Web file formats: HTML; JS; CSS; XML; PHP; JSP

Compressed/Archived file formats: ZIP; RAR

Executable files: EXE; DMG

Mobile Apps: IPA; APP; XAP; APK; ALX

 

If there are other common formats that you want to add, that is fine - especially if it's a format that you use in your creative practice, or that you are familiar with. This is only a minimum set of common ones and not a definitive list as there would be too many. As new technology is developed, these formats may fall out of usage and new ones may appear.

 

 

2. Requirements

For each of the formats selected you need to describe the following sections:

  • format name:
  • format type:
  • details (what software applications to create & access it?):
  • uses(what can you do with it? examples of usage - use links to online content):
  • pros & cons:

For example:

Format name: JPEG

Format type: image

Details:

JPEG is a commonly used method of "lossy" compression for digital photography images. The degree of compression can be adjusted, allowing a selectable trade-off between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality, and is the file type most often produced in digital photography or computer generated images.

The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is image/jpeg , except in Internet Explorer, which provides a MIME type of image/pjpeg when uploading JPEG images.

JPEG/JFIF supports a maximum image size of 65535×65535 pixels

Uses:

JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.

usage: as JPEG files are so ubiquitous. almost any website will have JPEG examples. Here are a couple of links to Artists that use JPEG images either in their creative practices or to document their creative practices:

Pros & Cons:

Pro - low storage size: JPEG images are extremely prevalent on the Internet because of their ability to compress images to a small size. This means rapid download, which is an advantage.

Con - loss of image quality: the main problem with the JPEG format is the "lossy" compression can cause degradation of the image where parts of the image appear pixelated or blocky and patchy due to the loss of information during compression. Once information has been lost, it cannot be restored, so it is necessary to save the original high quality image before compressing into JPEG format.

 

You don't need to say too much about each format - concise descriptions are all that is necessary. The glossary should provide an informative review of between 30 - 40 common digital media formats. You can group the formats according to the categories listed above, or form your own system such as alphabetical etc.

 

3. Specifications

Create a Word document to compile your review and either:

1. convert to PDF & upload it as an attachment to a blog post; or

2. insert the text into a static Page in your Wordpress.com blog.

You will receive assistance with technical issues in class.
