Audio & Video Processing

Audio & Video processing

Audio and video are both kinds of signals which are available based on the system in use and the infrastructure in analog and digital modes. Generally, processing audio-visual signals mean to improve audio and video quality, to reduce or remove signal noises, and to increase video clarity and definition. All these processes are meant to be done by controlling video color, contrast, and brightness, setting and editing audio signals, compressing and coding audio-visual signals, and identifying a unique feature in the video, and separating the specified part. Nowadays, using video process and machine vision is applicable in almost every field like industry, astronautics, astronomy, medical, robotic, agriculture, meteorology, advertisement, archeology, etc.

In some CCTVs, there’s a capability called Video Content Analysis (VCA) which can be the replacement for the monitoring room. This smart system can analyze and process video events using face detect, motion detect, people counting and tracking function abilities, and in case of detecting any illegal event, it warns the operator through alarms. Using this system, minimize manpower, saves the operator’s time and energy, and increases safety in crowded organizations and places.

With the expansion of intelligent robots and machinery, audio-visual processing function abilities have been getting into more consideration than before. As humans, based on our intelligence, we can detect and identify the surroundings and their sound and speech. Smart robots and machinery, on the other hand, require audio-visual analysis and process in order to contact, respond, and react to the surroundings.

Nowadays, intelligent robots and machinery are designed in a way that they can detect the languages and sounds they can also respond to them. Or, they can identify their moving direction with burst photo shooting which shows obstacles on their way. These reactions are occurred by powerful hardware and software through complicated and heavy processors; for example, smart speakers and sound assistants from huge companies like Apple, Google, and Microsoft are using sound and speech detector function abilities.

With the development of technology, audio-visual processing features have been expanded in different fields and it saves time and costs because of the smart system’s accuracy and minimum occurred errors. Besides, the system’s high-speed performance based on the momentary and non-stop processing has increased the usage of this technology, in a way that its elimination disrupts many industries.

In radio and television production and broadcast chain, there are a group of electronic circuits that process the input audio and video and therefore, offer high-quality output. One of the most important products in this regard is the C-UD-3G card which can embed the processed audio on visual signal and transform different audio-visual signal formats to each other. Besides, it delays the audio signal syncing with the video signal in real-time audio transmit format. By having a different function in one card, the C-UD-3G card has become more popular and worthy.

Another product is DA-DV-2X8-3G 1 to 8 or 2 to 4 digital signal splitter. This card improves the efficiency and quality of signals through the equalizer function and recovers the wastes due to the cable length. Options like Change Over and Recover have been considered in this product and in case one of the inputs disconnect, the outputs can be recovered by another input. Besides, in order to control and manage these products, the web user interface can be implemented. One of the most important facilities of these products’ UI is the ability to detect the cable attachment to the card’s input and output ports (Termination Detection), and therefore, it can be managed by just observing the product’s interface panel. Also, in the case of products upgrade, users can download the upgrade file from Haguenet’s website.

Other products like audio-visual processors, digital to analog signal transformers and vice versa, audio-visual splitters, digital to optical fiber signal transformers, and vice versa are used in broadcast studios. Due to the improvements in technology, Haguenet Company is always trying to update its featured products and to design and offer new approaches according to new technologies. For example, today most of the studios transmit audio-visual signals through web and IP impressively reduces cabling costs. By offering “IP Domain Strategies”, Haguenet Group provides this technology not requiring a change in studios’ infrastructures.
