Real time video freezing detection implementation on FPGA

In the recent years the demand for real time video delivery has been increased. Hence, real time video distributers must ensure that the end-user quality-of-service is met (QoS). There are multiple conditions which can have influence on the transmission of video content, such as type of transmission, channel capacity, data loss, coding etc. Data loss mostly occurs in packet switched networks. This causes the encoder, on receiving side, to repeat the last good received frame, because of the lack of video stream. This is called video freezing issue or frame freezing, and it can appear in source of transmission and also in the receive side. Frame freezing effect is one of the common degradations in the quality of a video signals. Processing digital video in software can be computationally intensive task, even the simplest of algorithms can consume a great amount of memory. In this paper FPGA parallelism is exploited for implementation of video freezing detection algorithm.
