Abstract
A method (300) and an apparatus (110) for a communication device for controlling an image portion and an audio portion of a push-to-video communication are disclosed. The communication device (110) initiates the push-to-video communication (304), establishes the push-to-video communication (306), transmits the image portion and the audio portion of the push-to-video communication (308), and makes control of at least one of the image and audio portions of the push-to-video communication available (310) for other communication devices involved in the push-to-video communication. The communication device (110), after making the control of at least one of the image and audio portions of the push-to-video communication available, continues to transmit the corresponding portions of the push-to-video communication (312). The communication device (110) relinquishes the control when one of the other communication devices takes the control.
