In this blog article, we will delve into the world of digital video processing, exploring the latest trends, cutting-edge technologies, and valuable market insights that are shaping the industry.
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video is the fastest-growing medium being used for both content consumption, marketing, and even internal comms.
video is the fastest-growing medium being used for both content consumption, marketing, and even internal comms. Here are some of the latest stats on video usage: 82% of internet users watch online video. The average person watches 1 hour and 15 minutes of online video per day.
50% of marketers say video is the most effective form of content marketing. Videos are 1200% more likely to be shared on social media than text and images combined.
A Facebook executive predicted that their platform will be all video and no text by 2021. 72% of customers would rather learn about a product or service by way of video. (HubSpot). 90% of information transmitted to the brain is visual, and visuals are processed 60,000X faster in the brain than text.
A video signal is a sequence of time-varying images that capture motion and change over time. Unlike a still image that represents a spatial distribution of intensities that remain constant, a video signal involves spatial intensity distributions that vary dynamically with time.
In the modern era, digital video systems have become prevalent, and they heavily rely on digital techniques for processing and transmitting video data. High-definition video displays, such as DLP, LCD, LCOS (including variants like SXRD and D-ILA), and plasma, have become dominant in the television industry. These digital technologies operate differently from traditional CRT displays. Instead of “drawing” lines of picture information on the screen, they utilize an array of pixels to form the images. Each frame is displayed in its entirety all at once, with all pixels being activated simultaneously to create the complete image. This approach differs from the line-by-line scanning method employed by CRT displays.
The shift to digital video systems has brought numerous benefits, including improved image quality, increased resolution, and more efficient transmission and storage. Digital video processing allows for advanced techniques such as video compression, which reduces file sizes without significant loss of quality, enabling efficient streaming and storage of high-definition content.
Advances in computer technology have allowed even inexpensive personal computers and smartphones to capture, store, edit and transmit digital video.
The demand for digital video is increasing in areas such as video teleconferencing, multimedia
authoring systems, education, and video-on-demand systems. The development of high-resolution video cameras with improved dynamic range and color gamuts, along with the introduction of high-dynamic-range digital intermediate data formats with improved color depth, has caused digital video technology to converge with film technology.
Video Processing Technology for Enhanced Visual Experiences
In the realm of digital video, information is captured and represented through spatial and temporal digitization, resulting in quantized pixel intensities. Videos are composed of frames, which are rapidly changed to create an illusion of continuous motion, commonly referred to as the frame rate.
Video systems encompass a wide range of display resolutions, aspect ratios, refresh rates, color capabilities, and other qualities. Spatial sampling, an essential aspect of video processing, takes into account the sensitivity of the Human Visual System (HVS) to spatial frequencies. Each pixel’s value in a digital image is quantized with a finite precision, typically using 8 bits per luminance sample.
Temporal sampling is equally crucial, as it determines the smoothness of motion in a video. If the time gap between successive frames is too large, viewers may perceive jerky motion. The sensitivity of the HVS diminishes at higher frame rates. Most video formats employ temporal sampling rates of 24 frames per second and above to ensure a smooth viewing experience.
Digital video formats define the size of individual frames in terms of pixels and are displayed at a specified frame rate. For example, NTSC video utilizes a frame rate of 30 frames per second. Frame formats, such as Common Intermediate Format (CIF) with 352 x 288 pixels or Quarter CIF (QCIF) with 176 x 144 pixels, consist of three components for each pixel: luminance (Y) and two chrominance components (Cb and Cr).
Video processors are responsible for performing various functions, including upconversion, deinterlacing, frame rate conversion, noise reduction, artifact removal, lip sync (A/V synchronization), and edge enhancement. Deinterlacing is particularly important for digital displays, as most video sources transmit interlaced images, where only half of the image is transmitted in each frame. Video processors handle the conversion from interlaced to progressive format, ensuring a seamless viewing experience.
Noise reduction is another crucial aspect of video processing, as random noise can degrade the image quality. Spatial filters remove high-frequency data, while temporal filters evaluate multiple frames to identify and remove noise. By utilizing both spatial and temporal filtering techniques, visible noise can be effectively reduced, resulting in cleaner and more visually pleasing images.
Transcoding, a process of compressing video files with minimal quality loss, is integral to video processing. This technique enables the conversion of video files from one format to another, ensuring optimal streaming performance and eliminating format and bitrate issues. Transcoding plays a vital role in delivering content to users without buffering, while maintaining the best possible quality.
Video processing technology has revolutionized the multimedia industry, introducing advancements like Digital Versatile Disks (DVDs), Digital Satellite Systems (DSS), high-definition television (HDTV), and digital cameras. The field of video processing encompasses various areas, including video compression, video indexing, video segmentation, video tracking, and more.
As video processing technology continues to evolve, we can expect further advancements in image quality, compression efficiency, and interactive experiences. Emerging technologies like virtual reality, augmented reality, and mixed reality will further shape the future of video processing, offering immersive and engaging visual experiences to users.
In conclusion, digital video processing technology has opened up new possibilities for multimedia applications and entertainment. By optimizing spatial and temporal aspects, applying noise reduction techniques, and leveraging transcoding capabilities, video processing technology enhances visual experiences and enables seamless content delivery across various platforms. As the industry progresses, we can look forward to even more remarkable innovations and advancements in the field of video processing.
