SIGNIS has continued the ecumenical dialogue in cinema, which started in 1974 at the Locarno Festival. In 2017, SIGNIS representatives collaborated with members of the International Interchurch Film Organisation (Interfilm). SIGNIS continued also the ecumenical dialogue in cinema, which started in 1974 at the Locarno Festival. In 2017, SIGNIS representatives collaborate with members of Interfilm in 17 international film festivals to award an ecumenical prize (Cannes, Berlin, Fribourg, Oberhausen, Locarno, Kiev, Cottbus, Leipzig, Mannheim-Heidelberg, Montréal, Yerevan, Karlovy Vary, Zlín, Schlingel, Saarbrücken, and Warsaw). This policy of dialogue with other Christian churches was extended in 2002 to other religions in inter-religious juries. The first interfaith jury was organized in Tehran in 2003 at the Fajr International Film Festival. This jury comprises two jury members selected by SIGNIS and one or two Muslim jury members selected by the festival. The jury has to consider for its award a new Iranian feature film. The idea of jury representatives from different faiths was followed by the Brisbane International Film Festival (2003–2009), Nyon (2005–), Dhaka, Bangladesh (2006–), and Leipzig since 2016.<ref>Guido Convents, "The work of SIGNIS juries in Film and Television Festivals, p.132-139; Peter Malone (ed.), The Emergence of SIGNIS, Brussels, 2009</ref> SIGNIS develops this dialogue according to the criteria of the Pontifical Council for Social Communications published in 1989 in which "Manipulation or base proselytism, at times practiced in the media, is incompatible with the ecumenical task and with the spirit of inter-religious cooperation,... and as the decisions of ecclesiastical authorities affirm." In November 2016, the Cinema Desk of SIGNIS organized the 1st International Seminar of Film and Values in Barcelona with the Directorate of Religious Affairs of the Government of Catalonia and the Blanquerna Observatory on Media, Religion and Culture. This Seminar brought together the promoters of different international film festivals in which religion and its artistic expression stand central. The TV Desk SIGNIS supports the production and distribution of quality television programmes throughout the world, organizing seminars that bring together TV producers, programmers, and channels searching for opportunities for co-production or collaboration. SIGNIS also collaborates with the Catholic Radio and Television Network (CRTN). It continues and develops the work of Unda in the different TV festivals, which started in the late 1950s in Monte Carlo. In the following years, Unda had juries at other international TV festivals including
