The Duke of Cambridge is set to give a keynote speech at a conference on the future of children's media.
William and Kate will attend the Children's Global Media Summit at the Manchester Central Convention Complex on Wednesday.
The event brings together creatives, technology innovators, policymakers and executives from around the world to discuss the future of media for the younger generation and explore the impact digital technology will have on children's futures.
Kate will join a forum hosted by Sesame Street's Workshop, the charitable foundation of the children's TV show, on research commissioned into kindness.
William is due attend a short private meeting related to the Royal Foundation Cyber Bullying Taskforce before giving his speech.
Last month, William gave a speech at the launch of the taskforce at Google's London headquarters and said he hoped the UK could become a world leader on tackling cyberbullying.
Before going to the summit, the Duke and Duchess will speak to schoolchildren taking part in a focus group, called a "stepping out" session, where they can give editorial staff and content producers from children's television their views on new programmes.
