What is considered under video solutions?
Video solutions technology refers to the hardware and software systems put in place to ensure the smooth running of videos and even audios in the event. For any events, presentations, speeches, or even entertainment, they usually incorporate videos. There is no denying that video technology is essential to making sure your event is a successful one. It may be for capturing, recording, processing, storing, transmitting, or reconstructing a sequence of the still image to the scene in motion, It helps create an ecstatically pleasing and smooth transition of videos. Here, we will take a look at the basic understanding and specifications of video solutions and technology, what to look out for when sourcing for video solutions for your event.
Video Encoder in Video Solutions
A video encoder converts analog video to digital signal videos. It converts motion into electrical signals that can be read by some type of control device in a motion control system. It sends a feedback signal that can be used to determine position, count, speed, or direction.
The Packetizer is a higher-level communication scheme implemented within SUBLIBinal. The Packetizer functions by sending two extra pieces of information along with the data. These two pieces of information are a control byte and a size byte. The control byte is a way of informing the recipient that this is the beginning of a packet. The size byte tells the recipient how much data will be following it in the packet. This scheme allows for the verification of data and the correct retrieval of data over an asynchronous protocol.
This is so that data interpretation can be streamlined if a device is initialized in the middle of a packet. If this were to occur, programs could get confused by reading the last half of one packet and the first half of the next as a full packet. The Packetizer wraps information in a bundle to ensure that information is maintained. The Packetizer documentation has been broken up into three subsections: enumerations, structures, and available functions.

IP encapsulator takes an encoded video transport system and prepares the stream to be broadcasted over an IP network. Some standards support the transmission of video. One example is a real-time protocol (RTP). RTP was created to support the transmission of real-time applications such as audio and video. It does not guarantee the quality of service or resource allocation, but it includes some functions such as timing reconstruction, loss detection, security, and content identification. The IP encapsulator receives traffic from three main sources: the pre-encoded content being sent directly, the encoded content from the MPEG video encoders, and the output from the video transcoder. The output from the IP encapsulator is sent to the video streaming server. Packages can be broadcast or sent to the DRM or content database.
A radio frequency modulator (RF modulator) takes a baseband input signal and then outputs a radio frequency modulated signal. This is often a preliminary step in signal transmission, either by antenna or to another device such as a television.
The modulator converts the video and stereo audio from any A/V component, and most video game decks, into a coaxial cable output. After connecting your A/V component to the modulator’s input jacks, then connects the modulator to your TV’s antenna/cable input and select a channel for operation.

Live Video Cameras for Video Solutions
The cameras used for events are generally different from your typical everyday camera. Those cameras can, however, be used for an event if it is suitable. More notably, event cameras generally offer significant advantages over standard cameras. Key advantages include having a very high dynamic range, no motion blur, and latency in the order of microseconds. Purpose includes photography, videos, and Live Streaming.
Recorders, as the name shows, are used to record videos and allow videos to be stored and replayed should it be required. These recordings can be stored into a hard drive such as a thumb drive or CD for audiences or organizers to keep.
Networks can be set up to facilitate sharing of the videos. A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is a connection to the internet. Other shared resources can include a printer or a file server. In certain organizations, the computer network is also further segmented into intranet where it is privately owned and in a closed circuit. This provides higher levels of security and prevents the information or video from being shared with the entire public.
Some computer network hardware features Uplink ports designed for plugging in network cables. These ports allow a network to communicate with other outside networks. Uplink ports on home routers, for example, allow connecting to broadband modems and the Internet. Connections to an uplink port using the same cable or wireless link can transfer data both from and to devices on either. The terms uplink and downlink here apply to which end of the connection initiates a data transfer. While this means Ethernet crossover cables can be used for connecting a computer to an uplink port or by connecting two uplink ports to each other, it is highly inadvisable.
Uplink Applications for Video Solutions
- Connecting a broadband modem to a home router for Internet access.
- Connecting one uplink device (router, switch, and hub) to another. Plug the uplink port of one switch, for example, into the standard port of another switch to expand the network’s size.
Video Display devices
Display devices are also known as output devices. The operations of most video monitors are based on the standard cathode-ray-tube (CRT) design.
Other types of 2-dimensional display technology include
- Light Emitting Diode display (LED)
- Liquid Crystal Display (LCD)
- Digital Light Processing Display (DLP)
- Television set
- Computer monitors
- Head-mounted display
- Broadcast reference monitor
- Medical monitors
Key Video Aspects to take Note in Video Solutions
It decides how long they continue to emit light after the electron beam is removed. Persistence is the time taken for the emitted light from the screen to decay to 1/10 of its original intensity. Lower persistence requires higher refreshing rates to maintain the desired picture.
Resolution indicates the maximum number of points that can be displayed without overlap on the CRT. It is defined as the number of points per centimeter that can be plotted horizontally and vertically. Resolution depends on the type of phosphor, the intensity to be displayed, and the focusing and deflection systems used in the CRT.
Videos are 360p are typically suited for smartphones and other mobile devices as they require fewer data. However, it could appear blurry if portrayed on a large screen.
480p in Video Solutions
Most DVD is of 480p. A disc will generally only allow 480p maximum, but will still play well on a most laptop or desktop monitors. and, there are new advancements in disc technology providing Blue-ray disc or Blue-ray burner which allows for HD quality content.
720p in Video Solutions
High-definition quality starts at 720p. Most television broadcast channels display their content at 720p. The high definition looks crisp and sharp on most displays.
1080p in Video Solutions
1080p is also available and some used HD television stations. It is similar to 720p but even clearer and sharper.
Video Aspect Ratio
It is the ratio of vertical points to horizontal points to produce equal length lines in both directions on the screen. An aspect ratio of 4/5 means that a vertical line plotted with four points has the same length as a horizontal line plotted with five points.
