Accessing only the lower bandwidth data in video data stored in a scalable format requires skipping around within a data file to locate the desired data for a specified progression dimension for each image. This causes seek and rotational latency to occur for each image, increasing access time per image and lowering the available bandwidth for reading motion video from the storage system. Such increases in access time significantly degrade performance of local and shared storage systems, particularly for video editing and other video playback systems used in production, post-production and broadcast operations. To improve the performance of such systems, motion video data stored in a scalable format is processed so as to copy the lower bandwidth data into a separate file. These separate files can be accessed by video editing systems, media management systems and other devices or computer programs that use the lower bandwidth data.
A system for enabling a user to access a video program comprising a sequence of images, the system comprising:
A method for creating a lower bandwidth proxy of compressed motion video data, wherein the compressed motion video data encodes a sequence of images, the method comprising:
A computer program product, comprising:
