The Content Insertion capability within Tolka ADS allows broadcasters to insert relevant and localized advertising for audiences across different regions. Easy to integrate with existing playout automation systems, it automatically preschedules and splices video and audio content ahead of transmission, ensuring frame-accurate insertion. Video and banner ads are fully supported. Segments from one or more compressed program streams can be substituted with alternative content. Time and duration can be precisely specified. Commercials can be tailored to selected demographic groups. The content substitution history can be logged for future reference.
