Technology originally developed by NTT Service Integration Laboratories to objectively estimate a user's Quality of Experience (QoE) in IP-based video delivery services has been adopted as an international standard (ITU-T Recommendation J.247). The technology enables the quality of video delivery services to be checked and monitored.
NTT said previously existing technology cannot assess the effects of diverse coding systems and bit rates as used in video delivery services nor can it assess degraded video caused by packet loss characteristic of IP networks.
In response to this problem, NTT Service Integration Laboratories modeled quality degradation considering human perceptual characteristics (degradation in experienced quality due to coding and packet loss) based on a huge quality database making maximum use of NTT subjective quality assessment facilities and know-how. Then, based on this model, it developed technology to estimate QoE through the analysis of video signals. This technology enables the objective video quality assessment from the similar viewpoints of customers.
NTT's assessment technology was proposed for standardization at ITU-T, and after a 5-year worldwide performance evaluation contest held by ITU-T, four systems (including the NTT algorithm) out of nine candidates from the same number of institutions were approved as formal Recommendation J.247 on August 13, 2008 and released on August 22, 2008.

completed its acquisition of Helio, a joint venture between SK Telecom and EarthLink. The deal involved the exchange of approximately 13 million shares of Virgin Mobile USA Class A common stock, with a value of $38 million based on the average closing price of Virgin Mobile USA's Class A shares, as of two trading days before and two trading days after the date of announcement. In addition, SK Telecom and Virgin Group will each invest $25 million in Virgin Mobile USA for preferred shares.
