Parental Control

Parental control : A master control on the video on demand and IPTV sessions played by the child user . Parnet receives a live preview of media content ( such as trailer of movie , or random 2 minute snippet of ongoing IP channel ) child wants to view . Parent can view the media content on his SIP phone and decide whether to go ahead with request or block the show from child.

The differentiating factors of a realtime IPTV parental control application from any other parental control solution is that it doesnt not enforce the parent to review and restricts beforehand . Parent can review the channel / content settings at realtime ie as and when the child requests . Therefore it Saves the time involved in making beforehand channel settings .

Parents can customise the solution to meet their requirnements such as realtime notification to parent can be send via

  • Email ( channel link and summary )
  • IM ( Instant message ) with reply option
  • Call and Video preview with DTMF option

The two services are independent of each other and could be orchestrated using the service broker to act as one single service logic.
