DVD (digital video or versatile disc) format has been a popular digital format for storing audio and visual data.
Blu-ray was named for the blue laser used to read the disc. This digital format allows video and audio data to be stored with greater definition than on DVD.
Web streaming is available through the National Film Board of Canada, Films on Demand, and select databases. By logging in to your University of Lethbridge library account you can access this video content from wherever there is adequate internet access.
