CBS has begun testing high-definition streaming video.
Buried in the lab's section of the network's Web site is a gallery of short HD clips from shows such as Jericho, CSI: Crime Scene Investigation and Dexter.
TechCrunch was first to report the story and said the clips are available in H.264 format at 480p, with 720 p and 1080p coming later.
CBS has been overshadowed on the Internet in recent months by Hulu, the video portal operated by NBC Universal and News Corp. Hulu launched earlier this month and has attracted a score of content from other networks, studios, and sports leagues. Hulu has also begun testing high-definition streaming.
