• Moving images and audio

Black Hat Guy:   "I was watching and listening to this moving image with audio data stream on my LCD screen and speakers respectively about..."

Mrs. Roberts:      "You were what?"

Black Hat Guy:   "I was watching a video on my computer about..."

For both technical and non-technical usage?
