[1][2] In January 2007, TITV joined the operation of Taiwan Broadcasting System (TBS) and transformed into a non-commercial public media platform.

The operational guidelines of the Government Information Office (GIO) stipulated that the allocation, control, and use of broadcasting resources "should give consideration to the rights and benefits of minorities and disadvantaged groups".

Since the 1980s, social activism brought about major changes in Taiwan, and as native peoples became aware of their own identities and rights, they wanted to have more programs in their mother tongue.

In 1985, the indigenous TV program Spring in the Green Mountains was produced by Public Television Video Production (公共電視節目製播組), a subordinate unit of the Broadcasting Development Foundation (BDF).

In 2001, when the second tier of the cultivation program was in operation, the Deputy Minister of the CIP, Kao Cheng-shang (Bajack Gilin), commissioned PTS to promote the establishment of a TV channel exclusively by and for indigenous people.

In 2003, a budget of NT$330 million was earmarked, but was frozen by the Legislative Yuan pending the improvement of signal transmission in indigenous areas.

With the implementation of the policy of eliminating the involvement of political parties, political forces, and the military from the media, the Legislative Yuan reviewed the Statute Regarding the Disposition of Government Shareholdings in the Terrestrial Television Industry, Article 14 of which stipulated: "the production and broadcasting of indigenous TV programs should be executed by the Public Television Service Foundation effective the year following the Act’s promulgation".

The station has gone on to become a non-commercial public media platform for indigenous people to voice their opinions, ensure their right to be informed, and pass down their cultural heritage.
