TV-linked digital content delivery system patent acquired
~Interactive delivery of program info and ads based on TV audio~

Tokyo, August 17, 2018 --- D.A.Consortium Holdings Inc. (DACHD) and D.A.Consortium Inc. (DAC) announced today that they have acquired a patent for a system that delivers content and ads most appropriate to a user based on TV audio content recognition technology that is able to determine what programs or commercials that user is viewing.


Users are spending an increasing number of hours on the Internet yearly. Of the total number of hours spent on all types of media per day, the share of digital media, including smartphones and tablets, is more than 50%(*1). In addition, viewership behavior is evolving, such as users doing other activities while viewing. To respond to these changes, there is an increasing need for marketing activities that link mass media and smartphones, such as with TV stations creating program-specific SNS official accounts to disseminate information.

DAC has been developing ad delivery systems that use audio recognition technologies and acquired a patent(*3) that utilizes ACR(*2) to capture sound from TVs, radio and outdoor advertising through smartphone microphones in order to identify what content or advertising a user is listening to and deliver appropriate digital ads.

Patent overview

The newly acquired patent is for a system that is able to capture the sound of TV programs, TV commercials and other TV audio via the user’s smartphone microphone with user permission. This information allows companies to grasp in real-time a user’s online viewing behavior so that it can provide ad campaigns, TV programs, program promotion and other TV and digital media-linked information.

DAC will use this patent and combine it with various solutions, such as its own ad server FlexOne®,, an audio recognition technology developed by the affiliated company Evixar Inc.(*4), and a cloud-based CMS called dino(*5) offered by Revolver, Inc., to provide users more effective ads and content. In addition, by linking the patent with DAC’s DMP AudienceOne(*6), client companies will be able to deliver targeted and optimal digital ads and content according to each user’s offline media status.

By making real-time, interactive communication with users possible using TV audio, the newly patented technology will provide a better viewing environment and styles. At the same time, it will help enhance engagement with users and contribute to improved ad effectiveness.

This patent is not limited to TV, but can also be linked with radio, outdoor digital signage, in-store announcements and other interactive forms of communication.
