Today, the main standard for compression of the high -resolution video is HEVC. The standard is very wide and has a lot of options and modes, but solutions are gaining more and more popularity that can work hardware with 10-bit depth of color. If almost any PC copes with the decoding of such a video today, then it is more efficient to use specialized devices based on specialized chips (ASICs) or PLIS for coding, since such solutions will have the best performance ratio for energy consumption. Such devices include the ViteC MGW ACEDER complex, demonstrated at the IBC2017 event, which is now taking place in Amsterdam and will end on September 19.
Outwardly, this is a fairly ordinary device in a metal case, but it is intended to compress the video stream in real time. Montino formats are supported.264 and h.265, compression is completely hardware in both cases and occurs with a minimum delay — in the region of 60 milliseconds. The latest HEVC Gen2 processor provides, according to company representatives, the best in the industry quality of video compression in formats up to 4: 2: 2 with 10-bit color depth. The advantage over competitors reaches 20 %. The device is completely autonomous, supports signal entry through 3G-SDI, HD-SDI, SDI, HDMI, DVI or Composite interfaces and has a convenient web interface for remote control. The operator can monitor the process in the resolution of 1080p.
And now a small comparison: in the Intel arsenal there is an accelerator VCA installed in the PCI Express slot. Three Intel Xeon E3 V4 processors and up to 96 GB of DDR3 memory are soldered on the board at once. It is easy to calculate that the power consumption of such an accelerator will be in the area of several hundred watts, and, moreover, it is unable to work autonomously. VITEC MGW Ace Encoder consumes much less and is content with any source of direct current with a voltage of 28 volts. That is, the device can be used literally on «The front edge» news and immediately send a compressed video with high quality to the studio. If necessary, it can be encrypted by fly according to the AES standard. In addition, the introduction of tags and data from various sensors is supported in a video stream of tags. The entrance supports all video standards, including outdated, up to 1080p with a frame rate of up to 60 frames per second.
