The suppliers involved in Singapore Telecommunications' (SingTel) IPTV trial identified themselves. Alcatel-Lucent is performing the system integration.

System components include HP ProLiant servers, Microsoft TV's IPTV edition software, and Harmonic Inc.'s MPEG-4 AVC (H.264) DiviCom Electra video encoders, CLEARcut offline storage encoding solution, and NMX Digital Service Manager.

Harmonic said the SingTel IPTV technical trial represents the first use of offline encoding for on-demand services in a Microsoft environment.

That aspect of the trial is dependent on integration of the Microsoft software with Harmonic's CLEARcut storage encoding.

The trial began in October with broadcast TV and video-on-demand (VOD), including high-def content. The service will also feature PVR functionality.

In addition to leading the project, Alcatel-Lucent is working directly with SingTel to develop applications including audio support in different languages, music-on-demand, karaoke-on-demand, customer self-service, and bill viewing.

The two companies have worked together before. In June, SingTel selected Alcatel-Lucent to conduct a trial of gigabit passive optical networking (GPON) technology, and to install a residential Metro Ethernet trial in Singapore.
