PALplus
PALplus (or PAL+) is an analogue television broadcasting system aimed to improve and enhance the PAL format by allowing 16:9 (or 1.77:1) aspect ratio broadcasts, while remaining compatible with existing television receivers, defined by International Telecommunication Union (ITU) recommendation BT.1197-1. Introduced in 1993, it followed experiences with the HD-MAC (high definition) and D2-MAC, hybrid analogue-digital widescreen formats that were incompatible with PAL receivers. It was developed at the University of Dortmund in Germany, in cooperation with German terrestrial broadcasters and European and Japanese manufacturers. The system had some adoption across Europe during the late 1990s and helped introduce widescreen TVs in the market, but never became mainstream.[citation needed]
A similar system, developed in Japan at the same time and named EDTV-II/ Wide-aspect Clear-vision, allows for 16:9 NTSC broadcasts.
The MAC family of standards was adopted in Europe in 1983, primarily for Direct Broadcasting by Satellite (DBS) services. This was an evolution from older color TV systems (such as PAL or SECAM) fixing the problems of interference between luminance and chrominance, and providing a stepping stone for a future HDTV system. In 1986, a new high definition broadcasting standard, HD-MAC, was presented, offering twice the number of scanning lines compared to PAL. A transitional standard, D2-MAC was established. It had the same number of lines as PAL, but like HD-MAC it was designed for 16:9 widescreen content.
In 1989, the PALplus strategy group was founded. The goal was to develop an enhanced system for terrestrial transmission compatible with PAL. European terrestrial broadcasters felt the need to better position themselves in order to compete with satellite and cable operators, in view of the introduction of MAC widescreen broadcasts. While not attempting to produce HDTV standards of quality, the new format was meant to improve PAL in the following areas:
In the beginning, the task group consisted of the public broadcasting corporations of Germany (ARD and ZDF), Austria (ORF), Switzerland (SRG) and the United Kingdom (BBC and UKIB, United Kingdom Independent Broadcasters) together with the consumer electronics manufacturers Grundig, Nokia, Philips and Thomson. Sony as well as the Spanish (RTVE) and Portuguese (RTP) broadcasters joined the group later on.
At the Berlin IFA 1991, a first PALplus test transmission was demonstrated
At the Berlin IFA 1993, the first experimental PALplus broadcasts began. In the same year, the European Union approved a plan to support the production and broadcast of 16:9 programs.
In 1994, broadcasters began adopting the format. In the United Kingdom, Channel 4 starts to broadcast using the system in October. Nokia launched the first PALplus TV set in Germany.
