Low Latency Video

Real-time interactive or mission critical applications demand near-zero, the end-to-end delay incurred in streaming video between networking end-points. This requirement often originates from the time-sensitive nature of decisions taken at the client-end, based on the video content being streamed from the server. Therefore, measured glass-to-glass latency (from the time the video is captured at the server end to the time it is displayed at the client) must be as low as possible.

Based on expectations on glass-to-glass (G2G) latency, there are three primary bands of operation as relevant for different applications:

  • Nominal Latency Video: Systems that operate in this range offer a glass-to-glass latency of about 200-500 milliseconds, which is noticeable by humans but provides a real-time perception of the streamed media at the client end. The server and the client, typically, operate with a latency of multiple video frame durations each. Real time monitoring applications typically operate in this range.
  • Low Latency Video:

    Systems that operate in this range offer a glass-to-glass latency of about 60-200 milliseconds and try to match the overall system latency close to human reaction time to light & sound stimuli. The server and the client, typically, operate with a latency of within a few video frame durations each. Real-time interactive applications typically operate in this range.
  • Ultra

    Low Latency Video:

    Systems that operate in this range offer a glass-to-glass latency of about less than 60 milliseconds, and enable a true real-time user experience at the client, making the latency of operation almost unperceivable by humans. The server and the client each operate with a latency of a one to two video frame durations. Interactive precision and time-critical applications typically operate in this range.

Glass to Glass Latency = Server latency + Network latency + Client latency

Ittiam Low Latency Solutions

Ittiam Low Latency Media SDKs implement end-to-end optimizations right from video capture at the

low latency encoder

to video display at the

low latency decoder.

There are system-level optimizations for media codecs, media pipelines, streaming algorithms, software integration framework and device drivers to achieve the best-in-class latency for programmable processors. Field-proven algorithms and techniques to achieve the best trade-offs on latency and video quality are part of the

Low Latency Encoder

(Server) SDK and

Low Latency Decoder

(Client) SDK.
  • Optimized video capture and render driver implementation.
  • Sub-frame processing of both interlaced and progressive video to enable simultaneous operation of time-intensive tasks. This includes slice and field level processing for each of capture, display, encode, decode and pre/post processing operations in the pipeline.
  • Optimized

    video encoder

    configuration.
  • Patent pending rate control algorithm for regulating the network traffic.
  • Highly tuned multimedia-pipeline for optimal buffering at each stage.
  • Optimized
