Media synchronization within home network using set-top box as gateway
Techniques disclosed herein include systems and methods for transmitting TV program related content to IP connected devices on a home network, or other local area network. Users can watch television while simultaneously receiving content related to TV programs currently being displayed on a television. TV centric and TV program related content can be transmitted to IP connected devices. Moreover, this TV program related content can be displayed at the same time as a television program is being displayed on a television. As such, the system can provide media synchronization within home network using the set-top box as a gateway for delivering the content. Users can watch TV at home, and at the same time receive TV program related content on a laptop, tablet computer, mobile phone, etc.
