Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Multiple memory buffers are used to manage broadcast packet repair and presentation or storage.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner presents a demanded service while a secondary tuner scans for duplicate transmissions of the service, and if one is found, the version with the better quality metrics may be presented.

A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of receivers includes exploring streams broadcasted by a DVB network and streams broadcasted by an IP network and extracting services information from these streams, completing an information table, situated at the highest level in a hierarchy of services information tables, included in the service information DVB-SI transmitted by the DVB network by services information related to the IP network, and transmitting the completed information table in the streams broadcasted by the DVB network towards the receivers having two switchable receiving modules, connected respectively to a DVB and an IP services broadcasting network. The receivers are able to activate the reception of digital data of a service, equivalent to the service currently received, with a second receiving module when receiving conditions of a first receiving module are degraded.

The present invention proposes a method for transmitting a broadcast signal. The method for transmitting a broadcast signal according to the present invention proposes a system which can support a next generation broadcast service in an environment supporting a next generation hybrid broadcast which uses a terrestrial broadcast network and an internet network. Furthermore, the present invention proposes an efficient signaling method which can cover both the terrestrial broadcast network and the internet network in the environment supporting the next generation hybrid broadcast.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner receiving signals from plural antennae presents a demanded service while a secondary tuner uses a single antenna to scan for duplicate transmissions of the service, with handing off between the tuners being effected between scanning and service presentation.

A method and system for planning and running video-on-demand (VOD) advertising includes a planner for planning advertising campaigns and an ad selector for running selected advertisements from selected ones of the campaigns. The campaigns are associated with household demographic classifications, video content category categories, household geographic locations, and/or video viewing times. In response to a viewer requesting a video, the selector selects the campaigns corresponding to the demographic classification associated with the viewer, the content category of the requested video, the geographic location associated with the viewer, and/or the viewing time at which the requested video is viewed. The demographic classification is determined by using an identifier of the viewer's set-top-box. The selector may select the campaigns corresponding to the content categories of the requested video. The content categories are determined by using an identifier associated with the requested video.
