Abstract

V originále

Current high-speed computer networks provide sufficient medium for high-speed and high-bandwidth video transmissions such as High Definition Television (HDTV) streaming and videoconferencing. HDTV has at least twice the resolution of commonly used SDTV standards, thus allowing much more detail to be shown compared to the analog television or regular DVDs. There are two basic ways how to transmit the HDTV video. MPEG2 is the most commonly used format as the compression codec for digital HDTV broadcasts producing a stream of 30\,Mbps at the resolution of 1280x720 pixels and with 25 frames per second. It is also possible to transmit uncompressed HDTV video, that requires transfer rates of up to 1,5\,Gbps with the resolution of 1920x1280 pixels and up to 30 frames per second. This huge amount of data carry a new requirements on the network infrastructure as well as on the CPU and displaying units of the computers used for video delivery. Recently, we built an infrastructure and developed tools for transmitting of both the above mentioned HDTV standards and tested them in laboratory environment as well as in a wide area videoconferencing setup spanning Europe and USA.
