EZVIZ IoT proprietary cloud helps LG Group build a new audio and video platform

EZVIZ cloud open platform

LG Group is a world-renowned comprehensive multinational company, well-known for its electronic products, and its business covers a wide range of categories such as electronics, chemicals, and life and health. Among them, LG U+, founded in the 1990s, is a brand engaged in telecommunications services and Internet services.

With the continuous growth of the number of connected devices in recent years, especially the application of video devices, the platform has endured greater challenges, and all video streams need to be relayed through its own forwarding service, which has brought about a rapid rise in bandwidth traffic and costs.

The audio and video transmission engine service launched by EZVIZ is an audio and video service based on EZVIZ's advanced audio and video technology, combined with EZVIZ P2P transmission technology, which effectively reduces the cost of platform forwarding bandwidth and improves the outbound experience of terminals. This service helps LG quickly reconstruct the audio and video transmission mode, greatly reducing operating expenses, and effectively improving the user experience such as video loading, and continuously escorting the development and development of customers' smart home services.

With more than ten years of deep cultivation in the field of audio and video, EZVIZ has always stood at the forefront of the industry, experienced the continuous changes in the types and modes of information dissemination in the era of big data, and witnessed the continuous transformation of audio and video to improve the efficiency of thousands of industries and business innovation. Through the construction of a comprehensive open system, EZVIZ Cloud provides rich audio and video capabilities for the industry, helping partners to explore new opportunities based on their main business.

Audio and video transmission engine to build a new efficient transmission channel

EZVIZ audio and video transmission engine has the advantages of fast stream ingestion, security and stability, and strong resistance to weak networks, and has the advantages of low cost, convenient operation and maintenance, and one-stop service for enterprise customers, which is suitable for enterprises with wide audio and video application services and high frequency.

The EZVIZ audio and video engine mainly consists of three parts:

EZMediaAppSDK

The EZVIZ audio and video engine app-side SDK provides corresponding interfaces in a low-code way for customer apps to integrate the underlying capabilities of audio and video transmission, including P2P capabilities. Supports mainstream mobile client platforms Android and iOS.

EZMediaDevSDK

The device-side SDK of EZVIZ audio and video engine provides corresponding interfaces for devices to integrate the underlying capabilities of audio and video transmission, including P2P capabilities.

EZMediaServices

The EZVIZ audio and video engine server is mainly responsible for assisting in the establishment of P2P links and the forwarding of audio and video data.

Product features

Basic features

EZVIZ audio and video engine mainly covers three main audio and video business scenarios in security scenarios: real-time preview of equipment, recording and playback of SD card of equipment, and two-way voice intercom. In addition, it provides a one-question-and-answer transparent data transmission interface, which can assist customers in the transmission of commands and responses from the app to the device, and the specific business agreement is negotiated between the app and the device.

Media forwarding and P2P

In addition to the conventional server-side media forwarding capabilities, EZVIZ integrates the self-developed P2P solution that has been verified by large-scale online devices for many years into the audio and video engine products, and the customer App only needs to be integrated according to the specifications of the EZMediaAppSDK to maximize the P2P capabilities. With P2P, data can be transferred directly between the app and the device as much as possible, without the need for forwarding through the server.

Link switchover

In some complex network scenarios, P2P penetration takes a long time, for example, the end user initiates a preview operation on the device before the P2P link is successfully established.

In order to minimize the bandwidth cost of server forwarding, in this case, EZMediaAppSDK will first fetch traffic from the device through the forwarding service, and then after the P2P link is successfully established, EZMediaAppSDK will switch the stream data from the forwarding link to the P2P link, which can further save server bandwidth.

End-to-end logs

The EZMediaAppSDK and audio and video engine services monitor the end-to-end logs of important functions in the product to facilitate subsequent troubleshooting and analysis. It mainly includes the following scenarios: start preview, stop preview, start playback, stop playback, start intercom, stop intercom, data transparent transmission, P2P penetration, user authentication, and user-device relationship authentication.

EZVIZ audio and video products have basic log field definitions, and retain the ability to expand to meet the requirements of customer customization.

Data Operations

For some core metrics of audio and video products, such as the success rate of stream ingestion in real-time preview, the success rate of stream ingestion in playback, and the time taken to fetch streams, the audio and video product records data into the database and provides statistical methods to customers.

Privatized deployment

EZVIZ provides private deployment solutions to meet the needs of cross-cloud deployment, including public cloud, private cloud, physical machine, container/k8s, etc., and supports the deployment of services to the laaS environment specified by customers.

After the private deployment is completed, AppSDK and DevSDK can be directed to interact only with the services deployed in the customer's data center to ensure data privacy and security.

Product Advantages:

P2P technology advantages

Through years of online large-scale equipment verification and technology optimization, EZVIZ's P2P technology can achieve the world's leading P2P penetration success rate and flow extraction success rate.

Data Security

The current security policy of EZVIZ audio and video engine covers the data between the App and the service, the device and the service, and the data between the App and the device, and the data on each link is encrypted before transmission, which avoids the security risks of data transmission on the Internet in clear text and ensures the security of the data.

Lower traffic costs

The deployment of the audio and video transmission engine not only effectively improves the outbound traffic experience of end users, but also significantly improves its own services. At the same time, due to the optimization of the transmission mode, the bandwidth cost of the platform forwarding server can be greatly reduced, which can help partners save about 80% in actual cases.

With the advent of the intelligent era, the application value of audio and video capabilities in all walks of life continues to improve, in addition to the field of operators, including animal husbandry, retail chains, hotels and restaurants, etc., enterprises can establish an exclusive platform with the help of EZVIZ IoT proprietary cloud, which can not only achieve unified management and better utilization of data resources, but also effectively improve the audio and video experience and bandwidth cost control.
