Video conferencing involves transmission of video as well as audio over a network between people involved in the video conferencing, over a network. Typically, quality of conference sessions are affected by quality of network connection. If the bandwidth of the network is low, that that may cause call quality issues or call drops, which is not desirable especially in certain applications such as a surgery over video conferencing. Disclosed herein is a Conference Manager (CM) that can facilitate video conferencing over a low bandwidth network. The CM uses a producer unit and a consumer unit, for video capture and transmission, and a communication device for audio capture and transmission. The CM captures and combines audio and video data at a receiving end of the communication network. The CM also uses a fast block-wise data transfer mechanism for facilitating communication between the transmitting end and the receiving end.
