It is based on DRM(Direct Rights Management), thereby, it restricts users from making unauthorized copies that are often bought online from stores. HD DVD and Blu-ray Disc are formats for physical delivery which were adapted when WMV version was standardized by the SMPTE(Society of Motion picture and Television Engineers). It is now termed as VC-1. MPEG-4 AVC, AVS and MPEG-4 ASP are other competitors against this format. Furthermore, it can also provide support to the variable bit rate, average bit rate and constant bit rate. It enables makers to use non-square pixels as well. Lastly, it can process videos using frame interpolation in which intermediate animation frames are created between the existing frames. |
