Abstract

Many Television sets have a capability known as "picture-in-picture (PIP)" where an image different than the 'main' image is displayed in a separate rectangular area of the screen, thus providing the ability to simultaneously view images from two different sources. In order to provide this capability, a TV or other video-display unit must have at least two tuners either both tuners are built into one TV or a second device with a TV tuner (such as a VCR) is connected to the TV and the output of that device is sent to the TV for display in the PIP window. It is the object of the present invention to utilize such a capability to display on one TV a text message sent from another TV.

Instant Messaging for Video Display Devices

Many Television sets have a capability known as "picture-in-picture (PIP)" where an image different than the 'main' image is displayed in a separate rectangular area of the screen, thus providing the ability to simultaneously view images from two different sources. In order to provide this capability, a TV or other video-display unit must have at least two tuners - either both tuners are built into one TV or a second device with a TV tuner (such as a VCR) is connected to the TV and the output of that device is sent to the TV for display in the PIP window. It is the object of the present invention to utilize such a capability to display on one TV a text message sent from another TV.

1. Given a TV or other video-display unit with the capability of displaying a PIP window and accepting video input from an external device. The TV may accept standard composite video or alternatively provide an optical or coaxial digital input. If the TV only accepts composite video, it will be necessary for an intermediate device to format a suitable video stream; eg, a solid-color background with the text to be displayed super-imposed on it.

2. Given a source device that allows a user to enter a message and choose a recipient device. Set-top box technology currently provides a means for users to interact with the TV via a standard remote control and is a good choice for implementing the proposed capability. The user indicates his intention of composing a message in some manner, such as pressing a function button on a remote control. The set-top box or alternative device providing the capability displays a window on the TV where the characters of the message being composed are displayed as they are typed. Upon completion of the message, the user presses another function button that indicates that the message is to be sent to the recipient device.

3. The source device that composed the message now sends the message to the recipie...
