`ABSTRACT
`
`A Video-on—demand (VOD) content delivery system has a
`VOD Application Server which manages a database of tem—
`plates for presentation of video content elements of different
`selected types categorized in hierarchical order, A web-based
`Content Management System receives content uploaded
`online in file formats with metadata for title and topical area,
`and automatically converts it into video data format compat-
`ible with the VOD content delivery system indexed by title
`and topical area. A User Interface for the system delivers
`listings data to the viewer’s TV indexed by title and topical
`area specified by the uploaded metadata.

`
`TECHNICAL FIELD
`
`This invention generally relates to the provision of inter-
`active television services through cable TV infrastructure.
`and more particularly, to a system and method for managing,
`converting and displaying video content on a video-on-de-
`mandplatform, andparticularly, advertising displays used for
`drill-down navigation and displays of consumer-generated
`classified ads 011 TV
`
`
`
`BACKGROUND OF INVENTION
`
`Cable television (CATV) systems are used to deliver tele-
`vision services to a vast majority of TV—viewing homes in the
`US. and other technologically advanced countries. The typi—
`cal CATV system has a cable service provider head end
`equipped with video servers to transmit CATV program sig-
`nals through distribution lines to local nodes and from there to
`TV subscriber homes. Within the subscriber homes,
`the
`CATV program signals are transmitted to one or more cus-
`tomer-premises TVs which are coupled to external set-top
`boxes for chamrel tuning or are equipped with internal cable
`channel tuners.
`Current CATV set-top boxes provide various functions for
`channel switching and program access between subscribers
`and the CATV head end. The more advanced digital set-top
`boxes are individually addressable from the CATV head end,
`and also allow subscribers to input via remote control units
`their selection inputs for transmission on a back channel of
`the connecting cable to the CATV head end, thereby enabling
`subscribers to access interactive television services and other
`types of advanced digital TV services. A primary type of
`interactive television system is referred to generally as a
`“video-on—demand” (VOD) system, wherein a viewer can
`enter a selection choice for a video program via the remote
`control unit to the set-top box and have the desired video
`program delivered instantaneously f
