AFR (Auto Frame Rate) - adjust the display frequency to the video frame rate.
ARM(architecture) - (from the English. Advanced RISC Machine - an advanced RISC machine; sometimes Acorn RISC Machine) is a family of licensed 32-bit and 64-bit microprocessor cores developed by ARM Limited.
x86- (eng. Intel 80x86) - processor architecture with the same instruction set, first implemented in Intel processors.
Openwrt- Built-in operating system based on the Linux kernel, and intended primarily for home routers. Core components include the Linux kernel, util-linux, uClibc or musl, and BusyBox. The size of all components is optimized due to the fact that in most home routers the amount of memory is severely limited.
Samba- a package of programs that allow access to network drives and printers on various operating systems via SMB / CIFS protocol. It has client and server parts. It is free software, released under the GPL license.
HDMI- High Definition Multimedia Interface (HDMI) - an interface for high-definition multimedia that allows you to transfer high-resolution digital video data and multi-channel digital audio signals with copy protection (English High Bandwidth Digital Copy Protection, HDCP).
CEC- Consumer Electronics Control (CEC) is a bi-directional serial bus using the industry standard AV.Link protocol for remote control of electronic devices.
HDCP- (English High Bandwidth Digital Content Protection - "Protection of Broadband Digital Content") - Media Protection Technology developed by Intel and intended to prevent illegally copying a high-quality video signal transmitted via DVI interfaces (for this HDCP interface is optional option), DisplayPort (For this HDCP interface is an optional option), HDMI, GVIF or UDI. The protected video signal can only be played on equipment that supports HDCP.
S / PDIF- S / PDIF or S / P-DIF - stands for Sony / Philips Digital Interface (or Interconnect) Format (also described as IEC 958 type II in the international standard IEC-60958). It is a set of low-level protocol and hardware implementation specifications describing the transfer of digital audio between various components of audio equipment.
Dolby digital- (English Dolby Digital, AC-3, ATSC A / 52) is a digital multichannel sound system developed by Dolby Laboratories, Inc. in 1991 to create high-quality optical phonograms of combined films.
DTS- Digital Theater System (Russian Digital Theater System) is a family of digital multichannel sound recording systems created by Digital Theater System (Digital Sea System) to demonstrate digital phonograms in cinemas in sync with film production.
HDR- High Dynamic Range Imaging, HDRI or just HDR - technologies for working with images and video, the brightness range of which exceeds the capabilities of standard technologies.
H.264- H.264, MPEG-4 Part 10 or AVC (Advanced Video Coding) is a licensed video compression standard designed to achieve a high degree of compression of the video stream while maintaining high quality.
H.265- H.265 or HEVC (English High Efficiency Video Coding - highly efficient video coding) - video compression format using more efficient algorithms compared to H.264 / MPEG-4 AVC.
VP9- open and free for the consumer video compression standard, developed by Google. Previously developed as Next Generation Open Video (NGOV) and VP-Next. It is an evolutionary development and successor of the VP8 standard. Both standards are used with the WebM container.
Wi-Fi- Wi-Fi Alliance trademark for wireless networks based on IEEE 802.11 standard. Under the acronym Wi-Fi (from the English phrase Wireless Fidelity, which can be literally translated as "wireless quality" or "wireless accuracy"), a whole family of standards for transmitting digital data streams over radio channels is being developed.
Bluetooth- (from the words of English. Blue - blue and tooth - tooth; pronounced / blutu /) - Production Specification of Wireless Personal Networks (Wireless Personal Area Network, WPAN). Bluetooth provides information exchange between such devices as personal computers (desktop, pocket, laptops), mobile phones, printers, digital cameras, mice, keyboards, joysticks, headphones, headsets on reliable, free, universally accessible radio frequency for neighboring communication. Bluetooth allows these devices to communicate when they are within a radius up to 10 m from each other (the range strongly depends on the obstacles and interference), even in different rooms.
