<human>:  What are the differences between a Blu-ray and DVD player?
<bot>: The main difference between a Blu-ray and DVD player is that a Blu-ray player can play Blu-ray discs, which have a higher quality of video and audio than a DVD player. Blu-ray players also have additional features such as internet streaming, 3D capabilities, and wider range of audio and video formats. DVD players do not usually have these features and typically only play DVDs or CDs. Additionally, Blu-ray discs typically offer more storage capacity than DVDs, allowing for more content on one disc.
