Bayer pattern

The "Bayer pattern", also known as "Bayer matrix", describes a photo sensor covered by a color filter (Bayer filter). The Bayer filter is a color filter array with a specific arrangement of RGB color filters in a square grid on the surface of a photo sensor. Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, camcorders, and scanners to create a color image. The filter matrix is 50 % green, 25 % red and 25 % blue; hence it is also called RGBG, GRGB, or RGGB.

The options for the Bayer pattern in ibaCapture refer to the order of the first two pixels of any possible combination: Blue-Green (B-G), Green-Blue (G-B), Green-Red (G-R) and Red-Green (R-G).

Encoding level

As the term is used in the standard, a "level" is a specified set of constraints indicating a degree of required decoder performance for a profile. For example, a level supported for a particular profile determines the maximum frame resolution, frame rate, and bit rate that a decoder can use. A decoder corresponding to a given level must be able to decode all bitstreams encoded for that level and all lower levels.

Encoding profile

Baseline Profile (BP): Originally created for low-cost applications that require higher security against data loss, this profile is used in some video conferencing and mobile applications.

Main Profile (MP): This profile is used for standard-definition digital TV broadcasts that use the MPEG-4 format as defined in the DVB standard.

High Profile (HiP): The high profile is the primary profile for broadband and disc storage applications, particularly for high-definition television applications. This profile, for example, was adopted for the Blu-ray Disc storage format and the DVB HDTV broadcast service.

GigE Vision®

GigE Vision® is an interface standard introduced in 2006 for high-performance industrial cameras. It provides a framework for transmitting high-speed video and related control data over Gigabit Ethernet networks at data transfer rates of up to 1000 Mbit/s.

Please note that not all cameras connected over GigE interface do support the GigE Vision standard.

GOP

GOP (Group Of Pictures) defines the number of pictures after which a full picture, a so called keyframe will be stored. The pictures between the keyframes are derived from the previous keyframe, in between, only changes of the pictures are stored. With a high GOP, possible encoding errors exist longer, with a low GOP, the bitrate and hence the memory requirements of the video stream tend to grow. The default setting 30 is fitting for most of the cameras.

H.264

An H. standard for highly efficient video compression. ISO/IEC MPEG lists the standard under MPEG-4/AVC (Advanced Video Coding). It is part 10 of the MPEG-4 standard (MPEG-4/Part 10, ISO/IEC 14496-10). H.264 is a video encoding standard for Blu-ray Discs and is widely used by streaming Internet sources (Vimeo, You Tube, iTunes, etc.).

H.265

High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a standard for encoding video content and images. It is the successor of the H.264/MPEG-4-AVC standard. The aim was to achieve twice as much compression compared to H.264/MPEG-4-AVC while maintaining the same quality. .

MPEG-4

An MPEG standard (ISO/IEC-14496) that describes, among other things, methods for video and audio data compression. MPEG-4 defines the compatibility to Part 2 of the MPEG-4 standard (MPEG-4/Part 2).

ONVIF

The Open Network Video Interface Forum (ONVIF) is a global and open industry forum with the goal to facilitate the development and use of a standard for the interface of network-based video devices. Started in 2008 by Axis, Bosch and Sony, the ONVIF aims to achieve interoperability between devices of different manufacturers, flexibility, future viability and a certain quality standard.

The ONVIF Core Specification covers the following areas:

    • IP configuration

    • Device detection

    • Device management

    • Media configuration

    • Real time viewing (live video)

    • Event handling

    • PTZ camera control

    • Video analysis

    • Security
