The Austrian AV technology manufacturer AV Stumpfl will present their uncompressed
8K and 4K RAW server systems at this year’s IBC exhibition in Amsterdam,
Netherlands.
The powerful Wings Engine RAW media server is the only server of its type capable of
playing out 4 simultaneous streams of uncompressed 4K (4:4:4) content at 60fps,
which has made it a household name in different branches of the AV industry in record
time.
RAW servers can also display video content using a full 12-bit colour depth, delivering
more colour information than the current media server standard, which is particularly
interesting for broadcast studio setups using the latest generation of LED displays.
The render engine allows for the use of high frame rate footage of up to 120fps and
makes it possible to create seamless 8K softedge blending panoramas.
Native image sequences like TGA, DPX or TIFF can be used without any need for
converting them into an intermediate codec format.
RAW servers can be equipped with two, four or eight channel 3G-SDI input cards that
support formats from SD (PAL, NTSC) to 3G-SDI (1080p) per channel.
The individual channels can be combined for capturing 4K at up to 60p either using
the Square Division or the 2-Sample Interleave method.
The new input card options make it a lot easier to integrate RAW media servers into
existing 4K broadcast workflows.
Global business development manager Helmut Protte comments on the growing
significance of 4K and 8K playback solutions:
“When it comes to the development of next-gen broadcast workflow components, we
are living in an exciting time. On one hand, many traditional networks are still
thinking in terms of HD, but the demand for media server systems capable of playing
out uncompressed 8K is already here right now. As we get closer to 2020, we will see
more and more setups that will require systems like our RAW server for processing
uncompressed video at high frame rates and with a colour depth beyond 8bit.”
