I.                   Introduction

Video Chat allows subscribers with cell phone the capability to send Voice, Data, Graphical and Video images to an individual or a selected group, where they can receive and view these signals on a TV channel.

The concept is to make a gateway that enables the sending of  voice, data, graphical, and video messages via cell phone to an individual and/or a selected group where it can be displayed on a TV monitor. The process utilizes both the cell phone network and the Cable Access Television (CATV) network infrastructures. It requires translation of the cell phone signals to CATV signals.

II.                Problem Solved

This idea fulfills the need for sharing or collecting subscriber’s views on a specific topic. For example, a group of high school students or distance learners can watch a show and comment on it or share project information. Groups of friends can exchange messages while watching TV or playing video games together.

Commercial Enterprises like advertisers, focus groups or market research organizations could use this capability to obtain feedback on topics of interest, the effectiveness of TV advertising (e.g., test ad information retention), reaction of the public to breaking news events or documentaries on topics relating to public policy.

It requires:

  • New devices in CATV Headend that can receive cell phone signals, convert those signals to RF and distribute them over the Cable Plant.
  • Modification to CATV set top boxes to provide authorization and mode setup capabilities.
  • Adding NetMeeting capability to the MSC or external to MSC (i.e., a NetMeeting server)

This is an extension to Cell Phone service. It allows phones concurrent usage with the TV. Any phone voice, data or graphics can be displayed on the television. There are hundreds of uses for just the communications industry, including: Watch TV and read instant messages; Watch TV and play games, Display your own commentary (Pop-Video) on Movies.
Since a user needs authorization to be in a viewing group, this feature can be sold as either a pay per view or subscription service.

III.             How it Works

The Video Chat Gateway is described as a process whose steps include:

  • Setting up Communication
  • Sending a message
  • Message Distribution
  • Receiving a message

Background

In CATV Network Infrastructure (see Figure 1) consists of a Headend and Cable Plant. The Headend is used for receiving, converting, and transmitting RF signals. The Cable Plant is normally a hybrid of fiber optics and coaxial cables, with amplifiers, splitters, tabs and other elements necessary to carry RF signals to/from the subscriber’s premises.

The Headend converts the received PCS signals to the RF signals and broadcasts them to the subscribers using a...
