14 DAY TRIAL // Finnish mobile phone maker Nokia has recently sold its enterprise-focused Nokia Broadcast Solutions unit to the Indian IT services major, Wipro, yet the value for the transaction hasn't been decided yet, according to reports. Said unit accounted for a number of 40 people who worked on the development of software and hardware that would enable mobile TV technology on the phone to locate and access the broadcasting network.
According to the news, the move is meant to allow Nokia to focus on the consumer segment of its business and leave aside the business-to-business one. Basically, the Nokia Mobile Broadcast Solution is a DVB-H server platform that supports mobile TV services. The platform can support current TV content while impacting very little the existing production systems.
The service was aimed at broadcasters and telecom operators, and it seems that Wipro has made an interesting acquisition, given the company's presence in the telecom area. Industry sources are reported to have said that Indian operators were likely to source video content extensively as soon as the 3G auction took place.
The DVB-Handheld (digital video broadcasting – handheld) comes as an adoption of European technology for over-the-air DTV broadcast to homes, while also integrating orthogonal frequency division multiplexing (OFDM), which is meant to offer efficient usage of the available bandwidth. In addition, OFDM also enables the transmission of multiple signals into the same bandwidth space, while spreading them over multiple data streams.
Moreover, given the modulation of different signals, the technology also enables the receiving device to recognize the signal it is set to receive from the range of signals that are transmitted. Basically, the content provider transmits live video and audio streams via an encoder, and the signal is then forwarded to a 3G streaming server, from where it is sent further to the coverage areas.
