The invention discloses a local area network video transmission method based on Amazon Echo Show, which relates to the technical field of internet videos and comprises the steps of collecting local ip addresses of a network camera, counting the distribution of the local ip addresses of the network camera, and binding the ip address with the highest distribution with a domain name; when the echo show requests an rtsp address from the service server, the service server determines whether to select local forwarding according to whether the local address of the network camera is bound with a domain name and the success rate of the past rtsp access type. The invention aims to reduce the flow cost of merchants and consumers, improve the fluency of videos and reduce the time delay of network transmission, and adopts a scheme of local transmission between an Echo Show with certain conditions and a network camera, so that the Echo Show and the network camera are not forwarded by a server under the condition of the same local area network and adopt local direct connection, thereby reducing the pressure of the server, reducing the flow cost, reducing the network delay, improving the video code rate and prompting the video definition.
Description
Technical Field
The invention relates to the technical field of internet videos, in particular to a local area network video transmission method based on Amazon Echo Show.
Background
Amazon Echo has been occupying the smart speaker market for several years, and the push of Echo Show has expanded the Echo line of products and Alexa voice assistants into more areas again. As can be seen from the display machine, the Echo Show is provided with a 7-inch touch screen, can be used for the functions of voice-assisted shopping, video watching, weather forecast, music lyrics, photos and the like, and can also be used in the fields of infant monitoring, home security and the like. With the use of a large amount of amazon Echo Show real-time videos, the original mode of forwarding videos based on a server causes merchants and consumers to bear high traffic cost, and the forwarding through the server increases the delay of video streams, so that the influence of network fluctuation is large.
Disclosure of Invention
The invention aims to reduce the flow cost of merchants and consumers, improve the fluency of videos and reduce the time delay of network transmission, and adopts a scheme of local transmission between an echo show with certain conditions and a network camera, so that the echo show and the network camera are not forwarded by a server under the condition of the same local area network and adopt local direct connection, the pressure of the server is reduced, the flow cost is reduced, the network delay is reduced, the video code rate is improved, and the video definition is prompted.
The invention relates to a local area network video transmission method based on Amazon Echo Show, which comprises the following steps:
collecting a local ip address of the network camera;
counting the distribution of local ip addresses of the network camera, and binding the ip address with the highest distribution with a domain name;
when Echo Show requests an rtsp address from the service server, the service server determines whether to select local forwarding according to the judgment condition.
Preferably, the judgment condition is whether the local address of the network camera has bound a domain name and the past rtsp access type has been successful.
Preferably, the collected local ip addresses of the network cameras form an ip address pool.
Preferably, if the domain name bound to the IP address of the network camera cannot be found in the domain name mapping pool, the echo show adopts a proxy policy.
Preferably, the past rtsp access type previous access success rate refers to an access success rate within 5 seconds past.
Preferably, the IP address pool is set to update once in 12 hours.
Preferably, the proxy policy is to jump to a local proxy server accessible for forwarding.
Detailed Description
The invention is further described below with reference to specific embodiments.
The invention relates to a local area network video transmission method based on Amazon Echo Show, which comprises the following steps:
1. collecting local ip address of network camera
2. Counting the distribution of local ip addresses of the network camera, and binding the ip address with the highest distribution with a domain name
When an echo show requests an rtsp address from a service server, the service server determines whether the local address of the network camera is bound with a domain name according to 2 conditions, and determines whether to select local forwarding according to the success rate of the past rtsp access type.
In another preferred embodiment of the present invention, the method for transmitting video over lan based on amazon Echo Show according to the present invention comprises the following steps:
1. collecting a local ip address of the network camera, and reporting an intranet address of the ipc through an mqtt signaling, such as the intranet address 192.168.1.100,192.168.31.55,172.16.0.33;
2. counting the distribution of local ip addresses of the network cameras, wherein most of the ip addresses are concentrated between 192.168.1.100 and 192.168.1.200, and binding the ip addresses with the highest distribution with domain names
For example, 192.168.1.100 has a domain name of local100.tuyacn. com
192.168.1.101 is local101.tuyacn. com
192.168.1.102 having a domain name of local102.tuyacn. com
…
192.168.1.200 having a domain name of local200.tuyacn. com
When an echo show requests a service server to acquire an rtsp address, the service server determines whether the local address of the network camera is bound with a domain name according to 2 conditions, and determines whether to select local forwarding according to the success rate of the past rtsp access type.
For example, the local address of the camera is 192.168.1.120, the domain name of the mapping 192.168.1.120 of the domain name pool is local120.tuyacn. com, when the echo show acquires the camera rtsp resource address, the service server will return an echo show address of rtsp:// admin:123456@ local120.tuyacn. com:443/echo show/xxxxxx if no access record is returned to the echo show address, the echo show address is rtsp:// echo show:123456@ static, and if the echo show address has a local access record in the latest 5s, the error retry is performed, an agent resource is allocated from the echo server, and the resource address rtsp:// echo show _ 123456@ rtsp.tuyacn. tx: 443/echo _ show/xxxx is returned to the echo show address proxy address, and/devsp id:// dvid: 456@ static/tuyacp.123xxxx: 443/xxxx, the network address is pushed to the echo show/xxxx 443;
if the local address of the camera is 172.10.0.22 and the domain name cannot be found in the domain name mapping pool, the proxy strategy is adopted by the echoshow.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
