STAFF FILM REPORT 67-2
VIETNAM - NOVEMBER AND DECEMBER 1966 - 1ST INFANTRY DIVISION, 6TH PSYCHOLOGICAL OPERATIONS BATTALION...
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Vietnam Television (Vietnamese: Đài Truyền hình Việt Nam, abbreviated THVN), also known as Saigon Television (Đài Truyền hình Sài Gòn) or Channel 9 (Đài số 9), was one of two national television broadcasters in South Vietnam from February 7, 1966, until just before the Fall of Saigon on April 29, 1975. It was the first television broadcaster in Vietnam. It was operated by the Vietnamese Bureau of Television (Nha Vô tuyến Truyền hình Việt Nam), part of the General Department of Radio, Television, and Cinema (Tổng cuộc Truyền thanh, Truyền hình và Điện ảnh) in the Ministry of Propaganda. Vietnam Television broadcast from the capital Saigon on channel 9 (4.5 MHz) in FCC-standard black and white. The other national broadcaster was the English-language Armed Forces Vietnam Network or NWB-TV on channel 11. Both channels used an airborne transmission relay system from airplanes flying at high altitudes, called Stratovision, as part of Operation Blue Eagle.
Vietnam Television's final programming aired the evening of April 29, 1975. The next day, the station was reconstituted as Saigon Liberation Television (Đài truyền hình Sài Gòn Giải phóng, SGTV) with a live broadcast of South Vietnamese President Dương Văn Minh's surrender. SGTV became Ho Chi Minh City Television on May 1, 1975...
