NEWSNTT provides HD video over IP for broadcast from Sapporo Snow Festival in real time & on-demand On February 5th and 6th of 2010, Nippon Telegraph and Telephone Corporation (NTT) concluded successful trials of their high speed wireless system, showcasing the viability of distributing high quality video through their high speed IP network. The NTT wireless technology uses a low-latency video-transmission system and a ultra high speed video server over the National Institute of Information and Communications Technology (NICT) network. NTT conducted two separate trials, both at the Sapporo Snow Festival: an uncompressed transmission of a live video capture over high capacity optical fiber to Hokkaido, as well as an on-demand retrieval of footage in Seoul for broadcast, from a server located in Osaka. The first trial, conducted on the 5th and 6th of February, was a transmission of live uncompressed video footage to the Hokkaido Broadcasting Television (HTB) station. Located at the Sapporo Snow Festival, the trial utilized an i-Visto XG-2s for packetizing and transmitting the high definition signal. The XG-2 is a low latency transmission system, with a minimum 1 millisecond delay from video input to output. The signal travelled on a 120GHz wireless system from the broadcast truck to the NTT Building, continuing from there via a 10Gbps ultra high speed IP network to the receiving HTB station. The successful transmission of high definition video without any encoding/decoding delays established the comfortable viability of using uncompressed video for broadcasting, with much of this footage used by HTB in several broadcasted TV programs. The second trial, conducted on the 5th and 6th of February at the Asahi Broadcasting Corporation in Osaka, was a successful demonstration of the on-demand transmission capabilities of the i-Visto XMS system. For the purposes of demonstration, a rough cut of footage from the Snow Festival opening ceremony was compiled. The editors at the Sapporo broadcasting location provided an uncompressed high-definition video as well as a DVCproHD version, compressed by an i-Visto gateway XG-1 on location, utilizing a new transcoder feature. After the initial live transmission over IP to the XMS system and the ABC station, the footage was ready and available for on demand retrieval by Taejon Broadcasting (TJB) in South Korea, the partner in this trial. TJB successfully retrieved the footage over a high speed 1-Gbps IP network connection, using an i-Visto XG-1 for decoding. TJB used the edited footage of the Snow Festival retrieved from the XMS system in their news program. This successful on-demand retrieval of high quality video footage across a great distance, ensures a level of convenience that can be offered by the proper usage of an intermediary server like the i-Visto XMS system.
