The growth of Internet applications has become widely used in many different fields. Such growth has motivated video communication over best-effort packet networks. Multimedia communications have emerged as a major research and development area. In particular, computers in multimedia open a wide range of possibilities by combining different types of digital media such as text, graphics, audio, and video. This paper concentrates on the transmission of video streaming over computer networks. This study is preformed on two different codecs H.264 and MPEG-2. Video streaming files are transmitted by using two different protocols HTTP and UDP. After making the real time implementation, the performance of transmission parameters over the computer network is measured. Practical results show that jitter time of MPEG-2 is less than H.264. So MPEG-2 protocol is better than H.264 over the UDP protocols. In contrast, jitter time of H.264 is less than MPEG-2 over HTTP protocol. So H.264 is better than MPEG-2 over the HTTP protocol. This is from the network performance view. However, from video quality view, MPEG-2 achieves the guidelines of QoS of video streaming.
