Stream Control Transmission Protocol (SCTP) is one of the TCP/IP protocol stack transport protocol. In this paper we aim for improving the video transmission rates by significantly enhancing the SCTP protocol frame structures. We make use of SCTP multi-streaming feature for determining various frame formats that defines the effective transmission. The proposed unidirectional delay technique is used to find the time lag occurred in transmission and thereby resolves the problem by resending the lost packets in a single SCTP association. This can broadcast the lost packets by differentiating the arrival of lost packet, before and after timeout. Enhanced SCTP (ESCTP) also increases the video quality of the transmission frames along with the throughput. By simulations, we observe that ESCTP can perform better than the standard retransmission approach that creates redundancies of data and can limit the time needed for retransmission.
