The current development of digital technology has led to an increasing use of video media. Various activities nowadays heavily rely on video media, ranging from learning, work, to entertainment. The rise in video media usage has resulted in video data traffic filling up the internet traffic, thus requiring optimization of video data size before transmission. This optimization can be achieved through compression techniques that aim to reduce the size while maintaining the quality. One of the compression standards that has good optimization for video data is the H.265 compression standard. Apart from considering video data size optimization, in order to cope with the increased video usage, it is necessary to pay attention to the video data transmission process to ensure that the received video data matches the transmitted video data information. During the video data transmission process, there is a possibility of disruptions that can cause damage to the resulting video. Therefore, techniques are needed to prevent and repair video data affected by transmission errors. The technique to prevent data damage during transmission is error resilient, which works by adding redundant bits that can be used to detect and correct errors. On the other hand, the technique to repair video data that has been affected by errors at the receiver side is called error concealment. To implement both techniques, an analysis of potential disruptions during the transmission process and their impacts needs to be conducted. Hence, an error simulation system will be created on the DCT component and packet loss simulation to assess the effects caused by these disruptions. This Final Project aims to address potential issues in video transmission, specifically the problems related to video data size that fills up internet traffic and the disruptions that may occur during the transmission process. To address the issue of video data size, the H.265 compression standard will be applied in this Final Project to reduce the data size by half. Meanwhile, to tackle the issue of disruptions in video transmission, a simulation system will be developed to simulate disruptions in the form of packet loss and error in DCT component, which will provide valuable information for analyzing the disruptions and enable error concealment at the receiver side. Overall, this project will result in a testbed capable of performing several processes, including video data compression, iv simulation of transmission disruptions such as error in DCT component and packet loss, and video data decompression. The other team members will focus on discussing the error concealment process, single error, and burst error. This research is expected to contribute to the development of error resilient and error concealment techniques.
