Method and apparatus for command and control of television receiver for video conferencing applications
First Claim
1. A method of aligning a television receiver for use during a video conference, comprising:
- receiving, from a video conference source, one or more alignment commands for one or more television alignment parameters chosen from a list including picture size or position parameters, picture geometry parameters, or picture video form at parameters, said receiving occurring through an existing command signal path within the television receiver originally provided for use other than by the video conference source and without requiring manual control inputs by an operator of the television receiver, decoding, at the television receiver, the one or more alignment commands to obtain corresponding alignment parameters for the television receiver; and
configuring a display output of the television receiver in accordance with the corresponding alignment parameters decoded from the one or more alignment commands.

Abstract
An alignment command is transmitted from a video conference application to a television receiver using an existing command path within the television receiver. The television receiver is then configured in accordance with the alignment command. Transmitting the alignment command may include formatting the command according to a protocol compatible with the existing command path within the television receiver. For example, a signal protocol compatible with a television remote control may be used. Further, the alignment command may be received at an input jack associated with the existing command path within said television receiver. Configuring the television receiver may be accomplished by decoding the alignment command to obtain an alignment parameter for the television receiver. This may include accessing a table (e.g., a look-up table stored in a memory) to obtain the alignment parameter. The alignment parameter may then be used to produce a display alignment command for the television receiver. The television may include means for receiving the alignment command from the video conference application and means for configuring the television according to the alignment command. The receiving means may include a command input path adapted to receive the alignment command. The television'"'"'s means for configuring generally includes a programmable controller configured to provide a display alignment command to configure the television according to the alignment command.

9. A television receiver, comprising:
-
a control port coupled to receive, from a video conference source and not from a manual input source, one or more alignment commands for one or more television alignment parameters chosen from a list including picture size or position parameters, picture geometry parameters, or picture video format parameters, the control port further coupled to provide the received alignment commands to an existing command signal path within the television receiver originally provided for use other than by the video conference source; and
a controller included within the command signal path and coupled to receive the alignment commands from the control port, the controller being configured to decode the alignment commands to obtain corresponding alignment parameters for the television receiver and to provide display alignment commands for the television receiver in response thereto. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A video conference system, comprising:
-
a video conference source including a television remote control simulator configured to provide one or more television alignment commands in a protocol recognizable by an existing command path within a television receiver that was originally provided for use other than by the video conference source, the alignment commands being for adjustment of one or more television alignment parameters chosen from the list including picture size or position parameters, picture geometry parameters, or picture video format parameters, the alignment commands being provided automatically during a video conference application, without manual control input, and the television receiver coupled to the video conference source and configured to receive the alignment commands through a control port in which the alignment commands are buffered prior to decoding, the control port being coupled to the existing command path within the television receiver. - View Dependent Claims (18, 19, 20)
