Embodiment approach
[0083] like figure 2 As shown, the method for establishing a lightweight WebRTC system suitable for Internet of Things devices in this application, an implementation thereof, includes the following steps:
[0084] Step 202: Establish a communication path between the local device and the peer device through P2P NAT traversal;
[0085] Step 204: Transmit audio and video data between the local device and the peer device, and store the audio and video data packets in the cache;
[0086] Step 206: Perform packet loss detection on the audio and video data in the cache, send a packet loss retransmission message to the peer device, and obtain the original data packet according to the packet loss retransmission information, and store it in the cache;
[0087] Step 208: Receive the packet loss retransmission request sent by the peer device, retrieve the data packet to be retransmitted from the original data packet in the cache, and send it to the peer device.
[0088] Step 202 may sp...

Abstract
The invention discloses a method and system for establishing a lightweight WebRTC system suitable for an Internet of Things device. The method comprises the following steps: establishing a communication path between a home terminal device and an opposite terminal device through P2P NAT traversal; performing audio-video data transmission between the home terminal device and the opposite terminal device, storing audio-video data packets in a cache; performing packet loss detection for the audio-video data in the cache, sending a lost packet retransmission message to the opposite terminal device,and simultaneously obtaining original data packets according to lost packet retransmission information, and storing the original data packets in the cache; receiving a lost packet retransmission request sent by the opposite terminal device, searching out the data packets needed to be retransmitted from the original data packets in the cache, and sending the data packets searched out to the opposite terminal device. The method and the system provided by the invention are simple in architectures, undivided in functions, suitable for the Internet of Things devices, have WebRTC basic functions, satisfy a basic audio-video RTC communication function of the Internet of Things devices and also can intercommunicate with a WebRTC application of a universal platform.
Description
technical field [0001] The present application relates to the field of Internet of Things multimedia communication, and in particular to a method and system for establishing a lightweight WebRTC system suitable for Internet of Things devices. Background technique [0002] WebRTC is an open source project promoted by Google, which aims to provide a simple JavaScript interface for web applications on browsers and mobile phones, enabling them to have RTC (Real-Time Communications) real-time communication capabilities. It means that developers who develop web applications on WebRTC browsers only need simple JavaScript statements to realize complex multimedia RTC functions, which greatly reduces development difficulty and development costs. Organizations such as W3C are developing WebRTC standard JavaScript API interfaces. [0003] In the technical architecture of the entire WebRTC project, the bottom layer of WebRTC provides the core technology of audio and video multimedia, inc...
