What is Low Latency for Video and Audio

Latency is a time delay that can occur when video data is transferred from one device to another. Several factors can affect latency, including physical distance, network configuration, and Encoding. This article will provide some insight into what causes low latency. Then, we’ll discuss how you can improve your latency.

WiFi interference causes low latency.

WiFi interference is when an outside signal interferes with the signal from your WiFi network. This can lead to higher latency and slower speeds. It can also cause frequent disconnections or the inability to connect to a WiFi signal. If you’re experiencing WiFi interference, you need to take action to fix the problem.

First, use a spectrum analyzer to see what’s causing the interference. While this will not always identify the problem, it will allow you to see what’s interfering with your WiFi connection. Other factors, such as radio waves or even other devices, may interfere with the signal.

WiFi access points that feature auto-channel can minimize interference. These access points periodically scan the available frequencies and choose the channel with the most precise signal. It’s also essential to ensure you don’t have cordless phones that use the 2.4GHz and 5GHz bands, as these can interfere with your WiFi connection. Newer cordless phone systems typically use the 1.9GHz band and won’t cause as much interference.


One method of controlling systems is by encoding control information at different times. Depending on the control information, it may be encoding low latency or legacy control information. Either way, the search space for encoding low latency control information is smaller than that of legacy control information. Sometimes, a single DCI encoding component 522 may encode legacy and low latency control information.

Low-latency communication technology uses a TTI (time-to-interval) of less than one subframe of legacy communication technology. For this reason, a single TTI can be transmitted in multiple locations.

Physical distance affects latency.

Latency is a physical characteristic of communication systems. Latency occurs when the transmission of signals takes more time due to distance. This is true regardless of the type of stimulus being transmitted. It is possible to overcome this limitation by routing packets over long paths. However, distance-based latency has a minimal effect on the user experience.

Distance affects latency by several factors. First, the distance between client devices and servers can affect transmission speed. For example, if you are in Cincinnati and want to visit a website hosted in Columbus, Ohio, your request will take between five and ten milliseconds. In contrast, the request will take about 40-50 milliseconds if you are in Los Angeles.

Network configuration affects latency.

Network latency affects the rate at which data packets travel from source to destination. The longer the distance between the source and destination, the more latency increases. Network components like routers and storage networks also affect latency. These components have different specs and speeds and will affect how much latency is experienced by users.

The more bandwidth your router has, the less latency you will experience. More bandwidth will also result in a higher internet speed. Most internet providers will recommend unplugging routers once in a while to reset the hardware and minimize the time that packets must travel.

OTT workflows require low latency

It is essential to use protocols that deliver video and audio with low latency to make the most of OTT workflows. These include LL-HLS, LL-DASH, and High-Efficiency Stream Protocol (HESP), which aim to deliver media content at sub-second latency. These protocols leverage WebRTC scope and HTTP-based delivery to achieve low-latency, high-quality video content.

Latency is the delay between the time of production and playout. This delay can be either intentional or unintentional. For example, a short delay can be necessary for closed captioning and live subtitling. Sometimes, a short delay can help prevent obscene content from being played on air. In these cases, the latency can range from fifteen seconds to one minute. For live video production, low latency is significant. This is because OTT workflows often involve talent and staff far from each other.
