1. A method for reconstructing video data, the method comprising:
storing, at a receiving device, a keyframe representing a face;
receiving, at the receiving device and from a transmitting device, information for generating additional frames, wherein the receiving device receives the information from the transmitting device at a transmission data rate measured in frames per second,
wherein if the frames per second of the transmission data rate is below a transmission rate threshold, the information comprises contour information related to one or more faces including data indicating an expression on the face represented by the keyframe, and
wherein if the frames per second of the transmission data rate is equal to or above the transmission rate threshold, the information comprises low bit rate compressed video corresponding to one or more frames; and
generating the one or more additional frames,
wherein if the information comprises the contour information, generating the one or more additional frames includes adjusting the keyframe based on both the contour information and the expression on the face, and
wherein if the information comprises the low bit rate compressed video, generating the one or more additional frames includes displaying, in their entirety, the one or more frames of the low bit rate compressed video.
