  • Always bring extra headphones, extra blank CDs. Bring cables for students to handle. ADD TO COURSE Additional format: midi For future classes, may want to get an iPod for demonstration purposes. You could also use it to backup/transport files. During the winamp exercise, have students make a favorites folder and practice moving/copying files into it, then loading that folder into winamp. When students rip files, have them move some of them into the folder to be burned. 2007/1/25: ripping mp3s does not work in wmp because there is no free mp3 encoder. Need to find a free one. In the mean time, you CAN rip .wma files from wmp instead. Would like to have time browsing online videos. 2007/02/28 In lab 2 we were not able to even transfer the files onto those computers. Lab 1 has a good track record in general. However, there can be problems with the sound drivers in lab 1: include the Dell sound driver in the files for the class: http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R94481&SystemID=DIM_PNT_P4_CEL_2400&os=WW1&osl=en&deviceid=2430&devlib=0&typecnt=1&vercnt=4&formatcnt=1&libid=3&fileid=122481 It is a good exercise for the students to copy the class files, but it seems to take quite a while. maybe if you were doing something else while the files are transferring?
  • What we are aiming for here is a comprehensive project (set of web pages) from start to finish. (you *could* use the materials on the CD) For the last portion of the class, should the students work on a project of their own?
  • The very first thing you are going to want to do is have students install powerpoint viewer 2003, and then coach them through working the PPTs
  • You could have the students research a player via hyperlinks and then report back to the class on their subject.

  • Colorado Free UniversityColorado Free University Towards a definition of multimedia …Towards a definition of multimedia … "Multimedia is media that uses multiple forms of information content and information processing (e.g. text, audio, graphics, animation, video, interactivity) to inform or entertain the user/audience. Multimedia also refers to the use of electronic media to store and experience multimedia content. Rich media is also a synonym for multimedia. Multimedia finds its application in various areas including, but not limited to, art, education, entertainment, engineering, medicine, mathematics, business, and scientific research." Consumption vs. Creation Although this course deals with a little bit of both, the general concentration will be on understanding basic multimedia concepts and technologies. Generally speaking, most computer users focus more on consuming multimedia than creating it. However, once you've begun to enjoy rich media content, it may only be a matter of time before you desire to create it yourself.

  • Colorado Free UniversityColorado Free University Standard multimedia playersStandard multimedia players "Media player is a term typically used to describe computer software for playing back multimedia files. Most software media players support an array of media formats, including both audio and video files. Some media players focus only on audio or video and are known as audio players and video players respectively. Microsoft Windows comes pre-loaded with 'Windows Media Player.' The latest version is WMP11(Comes with Windows Vista & can also be downloaded from microsoft.com as an upgrade to your current WMP), which is still in beta."  Winamp  Windows Media Player  Quicktime, iTunes  Real Player, Flash Player  (Hardware) Standard CD & DVD players

  • Colorado Free UniversityColorado Free University More about MP3sMore about MP3s "MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a popular digital audio encoding and lossy compression format, designed to greatly reduce the amount of data required to represent audio, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners. MP3 audio can be compressed with several different bit rates, providing a range of tradeoffs between data size and sound quality. MP3's extreme popularity makes it secure in its dominant position for the near future, with support from a huge range of software and hardware, including portable MP3 players and even some DVD and CD players. The large MP3 collections that many individuals have amassed will also ensure its longevity."
  • Colorado Free UniversityColorado Free University WinampWinamp "Winamp is a multimedia player made by Nullsoft. It is skinnable, multi- format freeware / shareware. It also now plays streamed video content, both live and recorded. In 2005 Winamp grew from 33 million monthly users to over 52 million monthly users, making it by some counts the third most actively used media player globally. Winamp's strength comes from a very active user community who continue to develop both new features, visualizers and skins." Interface Working with folders Creating and saving playlists Skins Visualizations

  • Colorado Free UniversityColorado Free University Understanding streaming mediaUnderstanding streaming media "Streaming media is media that is consumed (heard or viewed) while it is being delivered. Streaming is more a property of the delivery system than the medium itself. The distinction is usually applied to media that are distributed over computer networks; most other delivery systems are either inherently streaming (radio, television) or inherently non-streaming (books, video cassettes, audio CDs)." Internet radio  SHOUTcast  National stations  Local stations
  • Colorado Free UniversityColorado Free University Bitrates …Bitrates … "In digital multimedia, bitrate is the number of bits used per unit of time to represent a continuous medium such as audio or video after data compression. The bit rate is quantified using the 'bit per second' (bps) unit, often in conjunction with a prefix such as kilo (Kbps), Mega (Mbps), Giga (Gbps) or Tera (Tbps). While often referred to as 'speed,' bitrate does not measure distance/time but quantity/time. In digital multimedia, bitrate represents the amount of information, or detail, that is stored per unit of time of a recording." Example bitrates for audio (MP3) 32 kbps — AM quality 96 kbps — FM quality 128-160 kbps — Ok quality, difference can be heard by a sharp ear 192 kbps — Good quality, difference can only be heard by a few 224-320 kbps — High quality, nearly lossless quality
  • Colorado Free UniversityColorado Free University So what then is an iPod …So what then is an iPod … … and how do they work? "iPod is a brand of portable media players designed and marketed by Apple and launched in 2001. Devices in the iPod range are primarily digital audio players, designed around a central click wheel. The line-up consists of the video-capable fifth generation iPod, the smaller iPod nano, and the display- less iPod shuffle. The full-sized models store media on an internal hard drive, while the smaller iPod nano and iPod shuffle use flash memory. Like many digital music players, iPods can also serve as external data storage devices. In January 2007, Apple announced the iPhone, a device that combines the features of the video-capable iPod with mobile phone and Internet capabilities." shuffle nano iPod videoshuffle nano iPod video iPod wikipedia article iPhone demo 2007/01/11
  • Colorado Free UniversityColorado Free University What is "podcasting"?What is "podcasting"? "A podcast is a multimedia file that is distributed by subscription (paid or unpaid) over the Internet using syndication feeds, for playback on mobile devices and personal computers. Like 'radio', it can mean both the content and the method of broadcast. The latter may also be termed podcasting. The host or author of a podcast is often called a podcaster. The name has aroused some controversy for implying one needs an iPod to listen to podcasts, when in fact all portable media players will play them. Though podcasters' Web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital audio formats by its ability to be downloaded automatically using software capable of reading feed formats such as RSS or Atom."
  • Colorado Free UniversityColorado Free University A word about DRMA word about DRM "Digital Rights Management (generally abbreviated to DRM) is an umbrella term that refers to any of several technologies used by publishers or copyright owners to control access to and usage of digital data or hardware, and to restrictions associated with a specific instance of a digital work or device. Digital Rights Management is a controversial topic. Advocates argue DRM is necessary for copyright holders to prevent unauthorized duplication of their work to ensure continued revenue streams. Some critics put forth that copyright holders are attempting to restrict use of copyrighted material in ways not granted by statutory or common law." Music companies say Steve Jobs out of tune with no-DRM request

  • Colorado Free UniversityColorado Free University Browsing online videoBrowsing online video "Video clips are short clips in video format and predominantly found on the internet where the massive influx of new video clips during 2006 has been dubbed a new phenomenon, having a profound impact on both the internet and other forms of media. Sources for video clips include news and sporting events, historical videos, music videos, television programs, film trailers and vlogs. With the spread of broadband Internet access, video clips have become very popular online. As of mid 2006 there are tens of millions of video clips available online, with new websites springing up focusing entirely on offering free video clips to users and many established and corporate sites adding video clip content to their websites. The term viral video refers to video clip content which gains widespread popularity through the process of Internet sharing, typically through email or IM messages, blogs and other media sharing websites. The proliferation of camera phones means that many videos shot these days are shot by consumers. The availability of cheap video editing and publishing tools allows video shot on mobile phones to be edited and distributed virally both on the web by email." youtube.com video.google.com ifilm.com apple.com/trailers goyk.com
  • Colorado Free UniversityColorado Free University "Ripping""Ripping" "Ripping (also referred to as digital audio extraction) is the process of copying the audio or video data from one media form, such as Digital Versatile Disc (DVD) or Compact Disc (CD), to a hard disk. While the original media is typically digital, the extraction of analog media such as VHS video or vinyl records to a digital format can also be referred to as "ripping". To conserve storage space, the copied data is usually encoded in a compressed format such as MP3, WMA, or MPG."
  • Colorado Free UniversityColorado Free University Burning mediaBurning media "In computing, optical disc authoring, including DVD authoring, known often as burning, is the process of recording source material—video, audio or other data—onto an optical disc (compact disc or DVD). Authoring is commonly done in software on computers with optical disc recorders. There are, however, stand-alone devices like personal video recorders which can also author and record discs. "
