Abstract
A content based method is used to download/record digital video from networks to client stations and home VCRs. In this manner, the disadvantages associated with conventional time-based downloading of programs to analog video is avoided. The method includes the steps of receiving each of the video programs, identifying one of the programs from those received based upon frame signature matching, pre-loaded pattern searching, annotation signal searching or program bar code searching and saving the desired video program based upon the performed identification. Alternately a storage apparatus is included for storing selected signals. Furthermore, content based filtering is included for identifying selected signals and for transferring the identified selected signals to the storage device.
