Method for supporting scalable progressive downloading of video signal

Abstract

Disclosed is a method for enabling scalable progressive downloading of video signals. In the method, when a server transmits scalably encoded content data to a client, the server transmits some of the content data from a head of the content data to a tail of the content data according to transmission conditions, and transmits some of residual data of the content data having not been transmitted in the prior process. When scalably coded transmission content data is reproduced, the transmission content data are stored in a storage means as a file, the content data is read, decoded and output. Further, the recorded content data are read while an area having no recorded content data is skipped based on a specific code in the file.

Dependencies are inferred from the claim text.
