Streaming media monitoring application shines

Streaming media refers to the streaming of audio, video, and multimedia files in the network. The application of streaming media technology will bring about revolutionary changes in the network information exchange and have a profound impact on people's work and life. The following describes the application of streaming media technology in video on demand, distance education, video conferencing, and Internet live streaming.

Computer display screen signal capture

In electronic classrooms, game live broadcasts, video conferences, and projection fusion applications, real-time capture and capture of computer screens is required. Using the same three-dimensional T220E or T620E high-definition audio and video streaming media capture card, you can collect and store computer VGA screen signals in real time and high-speed HD to your computer. Especially the T620E HD dual-channel video capture card, which can simultaneously achieve two high-definition computer screen signal acquisition, and can synchronize audio transmission in real time, each resolution can reach 1920x1080. This is very advantageous for computer screen capture.

HD camera video signal acquisition

With the two-dimensional high-definition VGA / DVI / HDMI streaming media capture card, which can capture a variety of video camera signals, including VGA camera, HDMI camera and DVI interface camera signal. Can also be high-definition set-top box HDMI image effects collected to the computer, using professional software to digitally compare the differences between the HD set-top box program debugging differences, reducing the visual judgment and camera screen shot caused by the resolution, color output error, speed up the development Process and guarantee accuracy. The universal video capture card is used to map the HD set-top box operation menu to create a help document and manual. It solves the problem of blurring the virtual image captured by the camera and unable to capture the dynamic effect screen, greatly improving the competitiveness of the company.

Educational recording and editing

The educational recording and broadcasting industry has already introduced a number of professional high-definition VGA/DVI/HDMI streaming media capture cards with 3D, which is very suitable for use in teaching recording and broadcasting. Simultaneous multi-channel audio and video signals can be collected in high-definition at the same time, with high-definition cameras for excellent courseware recording, audio and video fully synchronized, through the support of Microsoft Directshow architecture third-party software, teachers can teach video sound, student question and answer video and other real-time recording The standard streaming media format required by the national exquisite course is uploaded to any server in the school, and the video live broadcast or on-demand broadcast on the campus network or on the internet is synchronized to achieve the function of remote interactive teaching and campus class communication.

Web TV collection

Capture HD or SD video source via the same 3D HD VGA/DVI/HDMI streaming capture card and record it in the video application software to your desired format (MPEG-1/2/4*&H.264) output, or through support Based on the Microsoft Directshow architecture, third-party software can be recorded in real-time into multiple streaming media formats and uploaded to the Internet to provide a variety of high-definition, high-quality program sources for IPTV. Online video conferencing and training.

Nowadays, video conferences have been vigorously developed, and higher requirements have been placed on the quality of video conference video. Because video capture cards are more versatile than USB cameras, more and more enterprise users are now using video capture cards. The same three-dimensional high-definition streaming media capture card can capture high-definition DVI / HDMI / VGA signal, the source device is not limited, but also increased the color component and composite video input, can capture 1080P high-definition source. Through the analog camera, the same three-dimensional high-definition VGA / DVI / HDMI streaming media capture card can receive high-definition or standard-definition video signals from the video input, through the support of Microsoft Directshow architecture third-party software real-time recording into the audio and video formats you need. Realize remote "zero distance" communication.

Webcast on demand

The development and popularization of the Internet has imposed higher requirements on the image quality of video. Because the video capture card is more versatile than the USB camera, more and more live webcast users are starting to use HD video capture cards. . With the three-dimensional two high-definition VGA / DVI / HDMI streaming media capture card can capture a variety of high-definition sources, and can achieve audio and video synchronization. It can not only collect computer screens, but also capture HD video cameras, and can also collect multiple video channels synchronously. The same three-dimensional high-definition professional audio and video streaming media capture card can receive high-definition or standard-definition video signals from the video input, through support based on Microsoft. Directshow structuring third-party software to record in real-time audio and video formats you need, compatible with common live on-demand software currently on the market, such as the century sunflower, polar domain, to achieve webcast and on-demand features.

HD medical video image acquisition

With the popularity of high-definition in the medical industry, many system vendors will consider acquiring high-definition solutions, with the three-dimensional high-definition VGA / DVI / HDMI streaming media capture card with medical camera recording real-time recording of high-definition medical images, through the support of Microsoft Directshow architecture Three-party software and powerful SDK secondary development kit, compatible with any medical device software, capture high-quality images, with de-interlace function, effectively remove image ripples and flicker to make the picture clearer, text and time superposition setting function, convenient Record the status and date of each acquisition.

Large-screen splicing, edge-blending large-screen splicing, and multi-channel large-screen splicing solution

With the popularization of multimedia screens in various industries, many system vendors will consider adopting high-definition solutions. HD VGA/DVI/HDMI streaming media capture cards are used to record high-definition images in real time with large-screen splicing recordings. The first support is based on the Microsoft Directshow architecture. Three-party software and powerful SDK secondary development kit, compatible with any device software, capture high-quality images, with de-interlace function, effectively remove image ripples and flicker to make the picture clearer, text and time superposition setting function, convenient recording The status and date of each collection.

Multi-channel HD acquisition system solution

With the same three-dimensional high-definition VGA / DVI / HDMI streaming media capture card also supports a machine multi-card, multi-channel and angle device is necessary to capture high-definition video.

Intelligent traffic, security monitoring system

It is used for intelligent traffic and security monitoring systems to collect human traffic and vehicles, or to use specialized intelligent software for pedestrian analysis and security monitoring.

About streaming media

The streaming media file format is a media format that supports streaming and playback. Streaming mode is to divide multimedia files such as video and audio into compressed packages after special compression. , continuous and real-time transmission from the server to the user's computer. In a streaming system, users do not have to wait until the entire file is downloaded before they can download the entire file. Instead, they only need to wait a few seconds or dozens of seconds before the file is downloaded. The corresponding player is used on the user's computer to play streaming media files, such as compressed video or audio, and the remaining parts will continue to be downloaded until the playback is completed.

A series of related packages for this process is called "streaming." Streaming media actually refers to a new media delivery method, not a new media. After the full application of streaming media technology, people can chat directly through the Internet to input voice; if you want to see each other's looks, expressions, as long as each side has a camera on it; on the Internet to see the products of interest, click after, explainer Images of goods and products will jump out; more realistic image news will also appear.
