The GS2985-INE3 Integrated Network Echo Canceller is a high-performance video processing device designed to reduce the effects of echo in video communications. It is a linear video processor that works by reducing echo, which is a form of distortion caused by the transmission of audio signals on the network. Echo can significantly degrade the quality of video and audio signals, resulting in poor performance and reduced user experience.

The GS2985-INE3 is a single-chip echo canceller solution suitable for digital switching, voice over IP (VoIP) and video conferencing applications. It is designed to detect, suppress and cancel echo present in the digital and analog portions of the audio link. The GS2985-INE3 can be used for both linear and nonlinear echo cancellation and can accommodate up to four channels of audio and video. It also provides an integrated clock recovery function, which can be used to ensure accurate transmission and reception of audio/video signals.

The working principle of the GS2985-INE3 involves identifying the echo and suppressing it before it reaches the receiver. This is done by a three-stage process. First, the signal is encoded using a Forward Error Correction (FEC) process, which is used to detect and correct errors in the signal. Next, the echo path is identified by analyzing the signal for spikes, time delays and other anomalies. Finally, the echo is attenuated using a technique known as Acoustic Echo Cancellation (AEC). This is done by comparing the reference signal to the received signal and subtracting any echoes that were detected.

The GS2985-INE3 features a Fast Connectivity Packet (FCP) file that allows for easy connection setup and playout. The FCP file contains all of the settings needed to configure the device, including settings for echo cancellation, clock rate, jitter buffers, packet size and more. The settings can be customized according to user requirements and can be fine-tuned to optimize the audio/video quality.

The GS2985-INE3 is designed for use in a variety of linear video processing applications, such as video conferencing, call centers, IPTV and web-casting. The device provides a low latency audio and video transmission solution that can be used in crowded and noisy environments. It is designed to deliver clear speech to up to four participants and can reduce echo up to 15 dB for clearer audio/video communications.

The GS2985-INE3 can be used in any type of linear video processing application where echo reduction is necessary. The device is designed to be easy to use and provides a simple and cost-effective solution for improving audio and video quality in any system. With the GS2985-INE3, users can ensure that their video communication systems are running smoothly, with minimal disruption and optimal performance.
