Local TV Control Using a Cisco IP Phone
To enable the TV control process:
• The channel guide and associated icons are defined in Cisco StadiumVision Director.
• The underlying commands used by the DMP to change the channel, input, and volume are
configured in Cisco StadiumVision Director.
• The images that make up the phone UI (including the icons) are stored in Cisco StadiumVision
Director.
• The IP Phone is subscribed to the Cisco StadiumVision Services on CUCM.
When the user touches TV/Volume on the IP Phone (for example to change a channel):
1. The IP Phone sends a request for video control services to Cisco StadiumVision Director.
2. The Cisco StadiumVision Director dynamically creates the XML (content and pointers) for the local TV
control device. Simultaneously, Cisco StadiumVision Director sends an HTTP request to CUCM for
the phone’s speeddial information (if using speeddials).
the phone’s speeddial information (if using speeddials).
3. The Cisco StadiumVision Director sends the XML information to the IP phone to update the touch-
screen content. The XML includes URLs to the screen graphics that the phone must show next.
These graphics are built by Cisco StadiumVision Director on the fly as the user navigates through the
