To cope with the challenges associated with the introduction of high-resolution video surveillance systems, a technology called High-Efficiency Video Coding (HEVC), aka H.265, has been developed. The peculiarity of H.265 technology is a higher compression rate, which reduces the cost of data storage and transmission.

CCTV manufacturers try to optimize storage and bandwidth consumption by recording higher resolution video only when certain actions are detected. If nothing important is happening, video will be recorded at a lower resolution. If people or vehicles are detected, the video will be recorded at a higher resolution.

An example of such a solution is the Smart H.265+ codec offered by Dahua. It reduces bitrate and memory requirements by 80% compared to the H.264 codec, significantly reducing capital and operational costs.

24/7 video surveillance requires a high storage cost for the recorded video. Efficient recording and storage of HD/UHD quality video surveillance footage has become a major challenge for the surveillance industry. The cost of transferring large amounts of data while maintaining video quality and storing this data increases the cost of the entire surveillance system.

To address these challenges, many manufacturers are continuously investing in new technologies and innovations that will help reduce the cost of operating surveillance systems. Manufacturers can achieve savings by modernizing their production lines and implementing the latest encoding standards (including MPEG4, H.264 and H.265). By doing so, their customers will be able to take advantage of the benefits offered by the new, much more efficient, encoding standards.

Implementing new standards requires hardware upgrades, and in addition, their market adoption may take an indefinite amount of time. In order to stay ahead of the competition, Dahua has decided to release a suite of software updates to the market to better utilize H.265. To take advantage of these additional algorithms, customers will simply need to perform a software update on their device that utilizes the H.265 codec. Below you’ll find out exactly what improvements are in store for users of Dahua equipment.

Adaptation to the situation – the video episodes are continuously changing, although these changes may be imperceptible to the human eye. How the human eye perceives an object depends on many factors. For example, our vision is more sensitive to changes indoors than outdoors. Smart H.265+ technology utilizes this difference in perception to improve encoding efficiency.

Dynamic ROI – More often than not, users of video surveillance systems are more interested in the movement of objects in the surveillance area than in the background against which this movement occurs. Smart H.265+ technology implements a strategy to automatically separate moving objects from the background using video analytics technology.

Once objects are separated from the background, Smart H.265+ uses different levels of compression depending on the different areas of the image of interest to users. Smart H.265+ can increase the compression level for the background area and decrease the compression level for moving objects, thereby improving compression efficiency.

Noise suppression. Noise not only affects video quality, but also increases bandwidth consumption and storage capacity. Traditional noise reduction techniques transform the entire image, and in the process, important details may be removed. Achieving a balance between noise reduction and video preservation is a challenge.

The Smart H.265+ video compression codec uses advanced video analytics technology to distinguish between motion and background areas, and applies varying degrees of noise reduction to each. The Smart H.265+ codec is able to reduce noise and maintain the expected video quality in the image region of interest. Thus, it can not only reduce noise but also preserve video quality while reducing the overall bitrate.

The industry’s transition to H.265 compression technology will improve the efficiency of video surveillance systems and reduce the cost of implementation and operation.

One of the most common uses for a video decoder, such as an IP video decoder, can be for applications such as pipelines. Therefore, it becomes necessary to consider some key important features to ensure ideal performance based on specific needs.

Codec Compatibility: Ensure that the video decoder has good support for various codec ranges such as H.264, HEVC (H.265), and VP9 to ensure efficient video encoding and decoding. This flexibility ensures seamless playback of video content from various sources.

Video resolution and frame rate: make sure decoders can support 1080p and 4K high-definition video in addition to the higher frame rate of 60fps. This allows users to enjoy crisp and smooth playback on the latest displays.

Latency and real-time video processing: low latency becomes important when real-time video capture and analysis is performed, such as during video webinars or conference calls over live video. Choosing a video decoder with maximum latency reduces the number of audio and video events that can be synchronized.

These fundamentals are the primary factors in determining whether a video decoder meets the requirements of the device or the demands of future technology development.

Comparing 4K and HD Video Decoders

The main difference when evaluating 4K and HD video decoders is the degree of resolution supported. 4K TV decoders are designed to support ultra-high definition with a measurable size of 3840 x 2160, which is four times the current resolution of standard HD, which is 1920 x 1080. In the case of 4K decoders, it is easy to recognize their value due to the high pixel count, which makes materialized projections more attractive when image sharpness is very critical. In addition to the differences in resolution, it has been observed that 4K decoders also have high processing requirements and higher bandwidth requirements to manage the increased data. For this reason, while 4K decoders are suitable for delivering higher quality images, their use on standard images defines them as higher than their HD counterparts in terms of hardware and network infrastructure. The use of either of these two options will be determined by the target image quality, available system and financial cost.

Considerations for IP video and analog video decoding

Several factors are equally important for IP or analog video and its corresponding decoding strategy. Since IP video is network-based, sending video information in digital form is possible over IP-based networks. These include available bandwidth, latency, and network support for RTSP or H.264 standards, among other commonly used factors. Moreover, the scalability of IP-based systems acts as an advantage as it makes integration and provisioning space for scaling up easy.

On the other hand, as far as common practice is concerned, decoding analog video, such as coaxial cable, is likely to be evaluated using older systems, while new applications use HDMI and IP decoders for higher efficiency. Decoders must work with NTSC or PAL systems, and some features will not be available, especially in analog versions. Analog decoding for older systems or some other specific purposes is preferred because of the cost and ease of use compared to the benefits of digital technology. For this reason, the choice between IP and analog video decoding as far as systems are concerned should take into account the current state of affairs, the vision for growth, and the task to be accomplished.

Object Tracking Sound+: sound that follows the object on the screen

Action movies with stunning sound design leave a vivid impression when viewed in theaters. This is due to the fact that virtually all walls, around the screen and even on the ceiling in movie theaters are equipped with multi-channel speakers with three-dimensional sound. Compared to two-channel audio, in which the speakers are located only on the left and right, multi-channel speakers in movie theaters provide a more realistic experience. So how do you recreate this atmosphere at home? Samsung has developed Object Tracking Sound+, which plays sound through six speakers built into the TV.

With Object Tracking Sound+, the sound moves across the screen, following the object in each scene. When a car in the frame moves from left to right or a heavy object falls from top to bottom, so does the sound.

Active Voice Amplifier (AVA-Active Voice Amplifier) technology

When a deafening thunderclap sounds outside during an important news report or a key scene in a movie, users may not be able to grab the remote control and adjust the TV volume in time. To solve this problem, Samsung specialists have developed AVA technology that recognizes extraneous noise and, if necessary, increases the volume of the voice from the TV screen.

A sound sensor mounted at the bottom of the TV’s center section senses sound coming from both the device’s speakers and the surrounding environment. The AI technology then compares the volume of the two types of sound. If the ambient noise is higher, the volume of the content being played selectively increases.

Q-Symphony: creating a multi-dimensional soundscape

One of the key elements to achieving realistic sound during content playback is three-dimensionality, which encompasses both horizontal and vertical sound characteristics. Until recently, TV and soundbar specialists worked on these parameters separately.

During the development process, the problem of dialog reproduction quality arose. When both the soundbar and the TV speakers played voices at the same time, the sound quality deteriorated noticeably. However, they were able to solve this problem by separating the main audio track from the entire signal and assigning different tracks to the TV speakers and the sound bar.

Why is video compression important?

The use of digital video capture was introduced in the 80’s. It was completely uncompressed, pure video information that required huge amounts of memory and playback system resources to play and store the files. But even today, compression and encoding is a prerequisite for recording any video information, despite the tremendous leap in the development of digital electronic technology. Otherwise, downloading, processing, editing, playing and storing video files will become a test of your nervous system’s endurance and the capabilities of your equipment.

How does video encoding work?

In the process of video encoding, the stream of video information is continuously analyzed by special software, and unnecessary/unimportant data fragments are simply cut off, this helps to significantly reduce the size of the video file.

There are two types of video compression: frame-by-frame (intra-frame) and inter-frame coding.

Frame-by-frame compression treats each frame of a video recording as a separate still image, similar to a photo in jpeg format. This technology is characterized by good video quality, but the reduction in video file size is insignificant because all frames are saved, even if there are no changes in the image for a dozen or even a hundred frames. In other words, out of a hundred identical photos, all one hundred are saved, not just one.

Inter-frame compression works on the polar opposite principle: during signal processing, the whole frame is analyzed, but only key changes from frame to frame are saved, as in animation, when you need to show the movement of the object, but the background and the surrounding environment are the same. This allows you to significantly reduce the size of the video file compared to the principle of intraframe compression.

Video quality after compression

Even the most advanced video compression algorithms result in loss of quality of the original signal. But the development of software products and codecs has reached the level where the loss of quality is almost imperceptible and indistinguishable from the original by the average human eye, especially the non-professional in the field of digital video processing.

In order to preserve the highest possible video quality while saving on video file size, you need to determine the main key points: video resolution, file size, method of video file transfer and upload, prevalence of static or dynamic scenes, color, contrast and similar conditions. An important factor affecting the quality and size of the resulting video file is the choice of codec and compression format.

Codecs

A video file must be compressed and encoded, and then decompressed and decoded by the same set of software tools – a codec, which includes tools for processing and playing the file. In other words, to view a video file you need to decode it with the same codec it was encoded with, for example, a video encoded in MPEG-4 codec needs to be decoded with the same MPEG-4 codec, otherwise you are guaranteed to have problems playing the file.

M-JPEG (Motion JPEG) compression standard

An unlicensed coding standard created and widely used in the 1990s that uses intraframe compression technology. The digital video sequence produced by this codec is an array of full JPEG images. Despite the fact that this codec allows to use a number of tools that reduce the file size, today it is rarely used because of the low quality of the resulting image, as well as for the minimum compression ratio.

MPEG-4 compression standard

Licensed encoding standard that uses object-oriented (inter-frame) compression, i.e. the movement of each object in the frame is tracked separately and the video signal is recorded based on these movements. The main advantage of this codec is a wide range of compression settings, which can be selected for any – low or high – data rate. This format is universal, it is designed for viewing sweat video in real time.

H.264 compression standard

A licensed copying standard that very significantly reduces the amount of digital video information while making minimal changes to its quality, especially when compared to M-JPEG and MPEG-4 codecs. This codec is designed to record video signal for a long time, as it requires small network bandwidth and hard disk space. The H.264 codec is the best tool when working in video surveillance systems, especially when shooting at high frame rates and high resolution. The only issue with this standard is that it requires more processing power to decompress and view video information than M-JPEG and MPEG-4.

Which standard to use?

In a video surveillance system, the signal from the camera is sent to the DVR, where the video signal is encoded (compressed). Depending on the relevance of the DVR model, as well as your requirements and the selection of the necessary video codec. The choice between standards can be reduced to how often you need to download and view the recorded video.

In non-professional video surveillance systems, with simple hardware characteristics of the equipment, as well as for the formation of several streams of video signal (for example, for video transmission over the network or remote viewing with a cell phone), it is recommended to use codecs M-JPEG and MPEG-4, as they are not demanding on system resources.
