Latency can be understood as the delay between the time a sample enters a system and the exact time it leaves the system. Thus, in a video over IP system, latency is the delay between the instant when the first pixel of a video enters a transmitter via a video input and the moment it leaves the receiver via the video output. Although some latency is necessary for you to get a reliable video stream that can play with minimum interruption, there are delays that can be eliminated or minimized. Below are some tips you can count on to achieve a lower latency for your video over IP system.

Bandwidth Matters

Since latency and bandwidth are closely related, the first step of reducing latency in a video over IP system has to do with ensuring that there is adequate bandwidth, particularly if there is a significant amount of data being handled by the network that the system is using. There are two main ways in which bandwidth issues can be dealt with. For instance, if your bandwidth is less than 10 Gbps, you can increase it to 10 Gbps. The other option would be to compress the video signal.

The Distance Factor

Latency is usually a significant concern when it is high enough to be perceived by the user. As such, placing the input device and user in the same space will make the delay more noticeable since the user can perceive the output and the input at the same time. However, it is imperative to understand that latency can increase with increased distance between the transmitter and the receiver. Therefore, to minimize latency, the distance between the transmitter and the receiver should be minimized but not to the extent that the user perceives the input device and the output device at the same time.

Correct Combination of Hardware and Software

Although compressing a video signal is essential for minimizing latency problems in the video over IP system, relying on the compression software alone can exacerbate the latency problem. In other words, a software-based solution can lead to increased latency due to CPU loads and memory transfers. Therefore, in addition to video signal compression, it makes sense to consider the architecture of your system’s hardware. The right combination of software and hardware will go a long way reducing the buffering time, and consequently, minimize latency.

The Takeaway

Overall, it is apparent that latency is a critical issue when it is high enough to be perceived by users. Furthermore, high latency can make the entire video over IP project unusable. Luckily, there are several tips that can help you to achieve the lowest latency possible.
