Methods and apparatus for generating, including and using information relating to archived audio/video data
First Claim
1. A method of operating a system to process image data for storage and retrieval, the method comprising the steps of:
- analyzing said image data to be encoded to determine, for each image represented by the image data, a level of encoding complexity;
encoding said image data according to a first encoding format to generate first encoded image data; and
storing with the first encoded image data encoding complexity level information indicating at least one determined level of encoding complexity associated with the first encoded image data.

Abstract
Archival storage and retrieval of audio/video information is described. Audio and/or video information is digitized, compressed and stored in an intermediate archive format (IAF), which preserves the content at a high-enough quality for subsequent retrieval and conversion into various formats required at the time of use or distribution. A single capture operation is performed with ancillary metadata being added to facilitate subsequent searching, indexing and format conversion. Captured data content is catalogued and indexed at or subsequent to the creation of an IAF file that includes the archived information. The IAF includes a family of audio-video digital encoding formats based on public standards. The encoding format used in any particular application is determined at encoding time from information provided by the archive system user. At encoding, the particular encoding scheme is selected to optimize a tradeoff between storage constraints and end use quality requirements.
