After a month of rumors, BrightSign has officially debuted its 4K resolution media player, dubbed the BrightSign 4K. Outputting a native 3840 x 2160 resolution at 60Hz via HDMI 2.0 and supporting buffered playback of both Full HD (1920×1080) and 4K resolution content, the player actually is the first to use the new H.265 video compression standard as well as JPEG, MPEG-2, MPEG-4, HEVC and AVC video. H.265 is similar to H.264 but uses about 50 percent less bandwidth for transmission via the network.
Of course, for content to remain 4K native and be delivered via the 4K media player, video must be captured on a 4K-capable camera, encoded and decoded using the new H.265 compression standard at 10 bits/channel, and fed to the display via HDMI 2.0 to preserve the original 60 fps frame rate. Any broken link in this chain of events adversely impacts video quality and the output falls short of what 4K is made to be.
In the BrightSign 4K, Elemental Technologies supplies the encoding required to deliver a 3840 x 2160 output. Elemental is the first to implement the HEVC specification with the capability of processing 4Kp60 H.265 content in real-time.
