Audio Video Quality Processing

Audio and video are both kinds of digital or analog signals. We can process them to improve their quality, in addition to removing jitters or increasing the 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, …

Nowadays, using video processes and machine vision is applicable in almost every field like industry, astronautics, astronomy, medicine, robotics, 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 detection, motion detection, people counting, and tracking function abilities, and in case of detecting any illegal event, it warns the operator through alarms. Using this system minimizes 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 voices and speech. Smart robots and machinery, on the other hand, require audio-visual analysis and processing to contact, respond, and react to the surroundings.

Nowadays, intelligent robots and machinery are designed in a way that they can detect languages and human voices. 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 caused 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 errors. Besides, the system’s high-speed performance based on momentary and non-stop processing has increased the usage of this technology.

In radio and television production and broadcast chain, there is a group of electronic circuits that process the input audio and video signal lines and therefore provide the desired outputs. One of the most important products in this regard is the Samim UDC – 3455 module card which can up / down / cross processing over SD / HD / 3G – SDI signals and convert audio-visual formats to each other.

Another product is DVD – 3214, 1 to 8 or 2 to 4 digital signal distributor. This module card improves the efficiency and quality of signals through the equalizer function and recovers the waste due to the cable length. Besides, to control and manage these products, the related web user interfaces can be implemented. One of the most important facilities of the UIs 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 product upgrades, users can download the upgrade files from SAMIM’s database.

Other products like audio-visual processors, digital-to-analog signal converters, audio-visual splitters, and digital-to-optical fiber signal transmitters. Due to the improvements in technology, SAMIM Group is always trying to update its featured products and to design and offer new approaches according to new technologies.
