determine whether at least a predetermined minimum amount of storage in the memory is available to receive the video stream;

transmit a video session invitation acceptance message to the video capture device via the one or more networks when it is determined that at least the predetermined minimum amount of storage in the memory is available;

receive a video stream from the video capture device via the one or more networks in substantially real-time,

buffer the video stream in the memory, and

output the buffered video stream to a display.

12. The video receiving device of claim 11 , wherein the communications interface comprises one of a data network interface or a cellular-based communications network interface.

13. The video receiving device of claim 11 , wherein the logic is further configured to:

transmit a video session invitation rejection message to the video capture device via the one or more networks when it is determined that sufficient storage in the memory is not available.

14. The video receiving device of claim 11 , wherein the logic is further configured to:

receive an end of transmission message from the video capture device, and

transmit an end of session acknowledgement message to the video capture device.

15. The video receiving device of claim 11 , wherein the logic is further configured to:

determine whether the buffered video stream should be immediately output to the display, and

output the buffered video stream to the display when it is determined that the buffered video stream should be immediately output to the display.

16. The video receiving device of claim 15 , wherein the logic configured to determine whether the buffered video stream should be immediately output to the display, further comprises:

logic configured to:

notify a user of the incoming video stream, and

receive a selection to view the incoming video stream from the user.

17. The video receiving device of claim 15 , wherein the logic is further configured to:

determine whether the buffered video stream should be saved for later viewing, and

deleting the buffered video stream from the memory when it is determined that the buffered video stream should not be saved for later viewing.

18. The video receiving device of claim 15 , wherein the logic is further configured to:

store the buffered video in the memory for later viewing when it is determined that the buffered video stream should not be immediately output to the display.

19. A streaming video system, comprising:

a video capture terminal configured to:

communicate with a first communications network;

receive an identification of a video receiving terminal from an address book maintained on another device;

capture video data;

transmit a video session invitation to the video receiving terminal;

receive a video session invitation acceptance message from the video receiving terminal; and

stream the video data to the video receiving terminal via the first network in substantially real-time;

wherein the video receiving terminal is configured to:

communicate with a second network operatively connected to the first network,

receive the video session invitation from the video capture terminal via the second network;

determine whether at least a predetermined minimum amount of storage is available to receive the video data
