ALTV (Active Learning Television) was a Thai educational television channel operated by Thai PBS, which strives to promote learning and the integration of teaching between home and school.
In May 2020, Thai PBS submitted a proposal to the National Broadcasting and Telecommunications Commission to operate a new educational digital television channel. Thai PBS was initially granted to temporarily operate a new digital TV channel for 6 months, in which ALTV launched on 1 July 2020 in digital, satellite television and online platforms.
On 1 December 2025, Thai PBS announced that ALTV would stop broadcasting, and its content would be moved to the main Thai PBS channel and its online platforms from January 2026.
ALTV broadcasts educational television programs for viewers of all ages, which are classified into 6 categories.
