| PAL Prog + New Digital Interface - Pioneer
This is very interesting. It is the latest I have just received from Pioneer following my latest query on the subject. It covers DVD players but also extends to plasma displays
Quote
"It is my understanding that any manufacturer or third party company that has been supplying a DVD player with PAL prog output, has thus far been doing so illegitimately. Subsequently large mainstream manufacturers like Pioneer have not offered any official upgrade or new models including PAL prog output capability. That is until they can legitimately do so.
Technically all plasma displays are indeed inherently progressive display devices. An interlaced signal is interpolated and produced on the display in progressive fields. In my mind the most significant shift in viewing experience will be the introduction of a digital interface rather than the restrictions and unnecessary digital to analogue conversion we have to apply with todays analogue connections (composite, S-Video, RGB, component, etc).
For example when playing a DVD: Data from the disc is converted into an analogue output from the DVD player whether PAL, NTSC, Interlaced or progressive. In the case of a digital display device like a plasma the analogue input signal is then converted and interpolated from analogue to digital in order to address the pixels on the screen.
Hopefully by the end of this year we will have (following approval from the worlds electronic, broadcast, film and music industries) a new digital interface (which has already been named HDMI / High Definition Multimedia Interface). This will spawn the introduction of new DVD players and display devices that can for example take the data from a disc, transmit it out of a new type of connector and securely pass it to a digital display device, (No more unnecessary A-D and D-A conversion). Now that should be
an interesting shift in performance . . ."
