Abstract:
The aim of this diploma thesis was to evaluate the performance of the state-ofthe- art mobile video delivery technologies. For this purpose two technologies, HSDPA and DVB-H, were chosen. The performance parameters for "high quality" streaming were investigated and all measurements were provided in live network.<br />A video service over HSDPA is an On Demand approach, which means that users are requesting any media at any time they want. DVB-H is a broadcasting approach like standard TV usage scenario, where all users are receiving the same media at the same time.<br />Using these technologies, video sequences were recorded in several situations - scenarios. Additionally, streaming of the most promising video content types was investigated. An objective video quality metric PSNR was used to compute the quality of received video streams at the application layer of the OSI model.<br />Moreover measurements at the network layer were provided.<br />In the HSDPA case a streaming server was used to provide these measurements.<br />However, this was not possible in DVB-H case, where we did not get access to the content provider. Therefore an alternative solution was chosen.<br />This thesis proves the ability of mentioned technologies to provide high quality video services.
