    Semi-synchronous video for deaf telephony with an adapted synchronous codec
    (University of the Western Cape, 2009) Ma, Zhenyu; Tucker, William D.
    As Information and Communication Technology (ICT) matures, communication services must be improved to meet the needs of all types of users. For some uses, current Video over Internet Protocol (IP) brings unsatisfactory and even unrecognisable quality of video sequences. Such communication does not always meet the needs of Deaf 1 people. Asynchronous video messaging, such as EyeJot (www.eyejot.com), offers Deaf people the ability to send and receive video messages like email. Unfortunately, communicating like this incurs much delay, resulting in slow response. Even though text messaging is popular among Deaf people via cellphone or Internet, but they would prefer to use sign language for communication. Video Relay Service (VRS) attempts to help Deaf users communicate with hearing people in sign language. VRS provides synchronous video and voice services to enable those who use sign language to communicate with hearing people through a relay interpreter across the world via the Internet.
