RTMi

RTMi is a digital television channel owned fully by Radio Televisyen Malaysia. It is also known as "Digital Terrestrial Television Broadcasting" (DTTB). Its test broadcast began in 2000 chosen residential homes surrounding Klang Valley for 6 months starting in September 2006, using the DVB-T standard. The test ended in March 2007, involving the installation and the interpretation of the "Set Top Boxes" in the respective homes. During the period, DTTB will be broadcast daily from 7:00 p.m. until 12 midnight (for 5 hours), previewing programmes that are shown on RTM1, RTM2, RTMi and Muzik Aktif. This digitalization test is estimated to cost over RM76 million. The transmitters used were provided by Harmonic Inc.

In April 2007, RTM has announced that digital transmission will persist despite the test period being over due to the positive response received during the period and plans for further testing involving different video/audio codecs.

Transmission

As of February 2008, the channel is available in the Klang Valley to the appropriate receivers at 674MHz and 658MHz. The 674MHz channel carries RTMi as TV 6 and Muzik Aktif as TV7, while the 658MHz channel carries a simulcast of RTM1 and RTM2 as well as RTMi (with its broadcasting hours extended, starting transmission at 3PM daily and ending sometime between midnight and 2AM), Muzik Aktif (which now broadcasts 24 hours), Arena (which Broadcasts for two hours between 3PM to 5PM), a demo channel called EPG, and Radio Aktif, a simulcast of the 7 RTM-owned radio stations in the Klang Valley.

Datacasting services in this project is the Superteks channel that include Berita Aktif airing 24/7. During the test period, a research to collect feedback and to access the number of viewers will take place.

During the off air hours, RTM no longer uses the Philips test card, instead opting for a colour bar.
