Machine learning is accelerating the pace of progress, it is time to explore this issue. Ai can really protect our systems in the future against cyber attacks.
Today, an increasing number of cyber attackers are launching cyber attacks through automated technology, while the attacking enterprise or organization is still using manpower to summarize internal security findings, and then compare them with external threat information. Intrusion detection systems deployed in this traditional way often
Streaming media transmission, video monitoring, video conferencing, and VoIP are all inseparable from the application of the RTP protocol, but when everyone chooses the RTP protocol based on experience or other people's applications, you may have wondered why we should use RTP for streaming media transmission? Why must we use RTP? Can TCP, UDP, or other network protocols not meet our requirements?
This article is based on my thoughts on the learning a
Unified Communication technology is one of the largest pieces of fat meat in the IT market today. Enterprises also see the benefits of a unified communication platform. So, is that true? What are the advantages? Let's take a look at this field through the article.
The Unified Communication technology integrates computer networks with traditional communication networks to unify applications such as telephone, fax, data transmission, audio and video conferenci
messaging tools, video conferences can achieve more intuitive and clear communication effects than voice calls. In addition, high-definition video conferences and telepresence can also show the subtle facial expressions of both sides of the communication, achieving a truly close-to-face communication effect. In this regard, video conferencing is a special Unified Communication Method.
In the current economic environment, video

The RGB mode is often used on the monitor, which is different from the pal or NTSC video standard.
Conversion between YUV and yiq
The conversion formula between YUV, yiq, and RGB is as follows:
Y = 0.299r + 0.587G + 0.114b
U = B ━ y
V = r y
I = 0.877 (R-Y) cos33 platinum 0.492 (B-Y) sin33
Q = 0.877 (R-Y) sin33 + 0.492 (B-Y) cos33
RGB is composed of three primary colors: R, G, and B. Similarly, YUV is composed of three elements: Y, U, and V. In pal

● Instant messaging (IM) and status presentation (presence ). Rich presence technology surpasses the simple "Green Dot" state, simple statuses only list basic statuses such as "do not disturb", "meeting", "exit", and "offline. Rich statuses are algorithms used to determine the user status based on activity, and sometimes the status is displayed across multiple devices.
● Audio and video conferencing. Ideally, the speech and vid
In recent years, broadband services based on IP technology have become increasingly popular. As a result, H.323 multimedia communication systems are no longer limited to private network user groups. Moreover, they are increasingly favored by Internet-based enterprise users. With the gradual popularization of H.323 system applications on the Internet, the conventional problem of firewall and NAT traversal has encountered new challenges, and this contradiction is becoming increasingly apparent.

SIP (Session Initiation Protocol) Conversation Initiation Protocol is an application layer control (signaling) protocol for network telephony and conferencing. It is mainly a multimedia communication protocol based on IP network. It can realize the signaling functions are also using RTP as a media transmission protocol. Originally presented by the IETF Mmusic (multiparty multimedia session control) workgroup.
