hvc-8701 4kp60 hevc broadcast video encoder card ? 1-ch 4k (2160p) or 4-ch fhd (1080p) @ 60 fps real-time encoding in main 8, main 10 or main 10 4:2:2 modes ? less than 35w (hvc-8701) power consumption ? 4k video capture over built-in hdmi 2.0, display port 1.2 or 4-ch sdi-3g video inputs (hvc-8701) ? simple-to-use api and example code for ffmpeg and gstreamer multimedia frameworks introduction hvc-8701 enables real-time 4k ultrahd (2160p60) hevc encoding at up to 20x less power consumption than a software-only solution. the hevc/h.265 codec is gaining momentum because it reduces bit rates by approximately 50% when compared to an equivalent quality video stream encoded using h.264, enabling more channels or higher resolution video delivery over the same infrastructure. it is particularly relevant for 4k ultrahd transmission which requires a much higher stream capacity. these improvements are achieved at the penalty of much higher computation complexity, with up to four general purpose server class processors required to perform a 4k 60fps software-based broadcast quality hevc encoding in real time. hvc-8701 is tailored for professional media processing and are capable of performing professional grade 4kp60 main10 profle hevc encoding at less than 35w power consumption. the hvc-8701 adapter additionally features 4k video capture over built-in hdmi 2.0, display port or 4-ch sdi-3g video inputs for acquisition-based encoding in contribution workfows. this card feature a simple-to-use api and example code for ffmpeg and gstreamer multimedia frameworks to streamline product development and their integration into existing applications. specifcation video input channels 1 (up to 4kp60, 8bit/10bit, yuv) / 4 (up to 1080p60, 8bit/10bit, yuv) video formats 4k, hd, sd frame rate pci express interface 4k / 4096x2160: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p 4k / 3840x2160: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p 1920x1080: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p 720x480: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p bnc (3g-sdi) interface 4k / 3840x2160: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p 1920x1080: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p 720x480: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p hdmi 2.0 / display port 1.2 interface* 4k / 3840x2160: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p 1080p: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p 480p: 60p / 59.94p / 50p / 30p / 29.97p / 25p / 24p chroma sampling format 4:2:2 / 4:2:0 interfaces pci express gen2 x8 / hdmi 2.0 / sdi-3g / display port 1.2 video compression compression h.265 hevc profle main / main 10 hevc tier main / high hevc level 1.0 / 2.0 / 2.1 /3.0 / 3.1 / 4.0 / 4.1 / 5.0 / 5.1 bitrate 4k format 3mbps ~ 128 mbps bit depth 8 / 10 bit rate control cbr / vbr elementary stream yes audio channels 4 format pcm operation mode stereo sampling frequency 48khz sampling bit depth 16-bit connectors hdmi 2.0 / sdi-3g / display port 1.2 feature frame rate and resolution control yes encoding control and manipulation yes full-feature api available yes dual encoding (4 fle from a unique video source) yes gop defnition i, ip, ipb, ibbb ancillary data and vbi yes operating system windows 8 & 8.1(32-bit, 64-bit), windows 7(32-bit, 64-bit) windows server 2012 & 2012 r2 (64-bit), windows server 2008 r2 (64-bit) linux kernel 3.13.0 (32-bit, 64-bit) development kits ffmpeg, microsoft directshow physical characteristic power consumption < 35w dimensions pci express half length full height 167.65 x 111.15 mm *output: auto scale to 4k/3840x2160p60 preliminary all product specifications are subject to change without notice last updated : 22-may-2015 features
