【Inter BEE 2011】NTT Electronics presents 'HE5100S', a subtitle compatible hi-definition 4:2:2 MPEG-2 HDTV/SDTV encoder for cable TV operators

　NTT Electronics presented and introduced the 'HE5100S', a hi-definition 4:2:2 MPEG-2 HDTV/SDTV encoder for cable TV operators that supports subtitles.

The 'HE5100S' is a hi-definition 4:2:2 HDTV/SDTV MPEG-2 encoder that is compatible with ARIB STD-B37 digital subtitle transmission and ARIB STD-B39 current voice modal control (voice control function). Furthermore, ARIB STD-B37 subtitle compatibility and ARIB STD-B39 voice control functions are options.

At their booth, they are doing a demonstration where video is output from two players over HD-SDI to two HE5100S units, encoded as 18Mbps MPEG-2 and output as DVB-ASI. After each signal is multiplexed and OFDM modulated, it is output as RF and displayed on a monitor. In addition, they are conducting a demonstration where subtitles are displayed using a subtitle inserter.

On subtitle support, Mr. Yoshiteru Yoda, Division Chief of the Sales HQ System Sales Division's 1st System Sales Division, explained that 'it was due to a multitude of requests.' Additionally, he went on to say that 'subtitle support is essential for encoders' because the Ministry of Internal Affairs and Communications has displayed guidelines for adding subtitles to all capable broadcast programs by 2017.

In the future, he also said 'we are planning to bring subtitle support to 'our AVC/H.264 encoder 'HVE9200'.'
