Abstract
A method and system are disclosed for archiving video content to film and recovering the video from the film archive. Video content and a characterization pattern associated with the content are provided as encoded data, which is recorded onto a film and processed to produce a film archive. By encoding the video data using a non-linear transformation between video codes and film density codes, the resulting film archive allows a film print to be produced at a higher quality compared to other film archive techniques. The characterization pattern contains spatial, temporal and colorimetric information relating to the video content, and provides a basis for recovering the video content from the film archive.
Claims16
A method for archiving video content on film, comprising:
- encoding digital video data by at least converting the digital video data into film density codes based on a non-linear transformation;
- providing encoded data that includes the encoded digital video data and a characterization pattern associated with the digital video data;
- recording the encoded data onto film in accordance with the film density codes;
- and
- producing a film archive from the film having the recorded encoded data.
A method for recovering video content from a film archive, including:
- scanning at least a portion of the film archive containing digital video data encoded as film-based data and a characterization pattern associated with the digital video data;
- wherein the digital video data has been encoded into film-based data by a non-linear transformation;
- and
- decoding the film archive based on information contained in the characterization pattern.
A system for archiving video content on film, comprising:
- an encoder for producing encoded data containing film-based data corresponding to digital video data and a characterization pattern associated with the video data, wherein the digital video data and pixel values of the characterization pattern are encoded to the film-based data by a non-linear transformation;
- a film recorder for recording the encoded data onto a film;
- and
- a film processor for processing the film to produce a film archive.
A system for recovering video content from a film archive, comprising:
- a film scanner for scanning the film archive to produce film-based data;
- a decoder for identifying a characterization pattern from the film-based data, and for decoding the film-based data based on the characterization pattern to produce video data for use in recovering the video content;
- wherein the film-based data is related to the video data by a non-linear transformation.
