Sony HDCAM-SR VTRs - the RGB 4:4:4 full-bandwidth high-definition VTRs at the top of the Sony HD VTR lineup - have been well received, especially in movie-making, commercial productions, and high-end television production applications, due to their unprecedented picture quality and system functionalities.

As HD-based programme origination has become more commonplace, demand has steadily escalated for increased levels of quality criteria: even more video bit rates, higher frame rates, and greater format flexibility.
