Multimedia technology integration function

Four characteristics of multimedia technology: 1) Integration adopts digital signals, which can comprehensively process a variety of information such as text, sound, graphics, animation, images, videos, etc., and organically combine these different types of information. 2) Interactivity Information is organized in a hypermedia structure, which can conveniently realize human-computer interaction.

Multimedia integration is mainly reflected in the integration of media. Multimedia features: controllability. Multimedia technology is computer-centered, comprehensively processes and controls multimedia information, and expresses it in a variety of media forms according to human requirements, while acting on people's multiple senses. Interactivity.

Multimedia technology is integrated, interactive, intelligent and expandable. Multimedia isA communication technology that integrates sound, image, graphics, text and other ways, which can play the role of information dissemination, ideological exchange and emotional expression.

Integration Multimedia technology is the organic integration of multiple media, including the integration of transmission, storage and presentation media equipment. In the early days, various technologies were single applications, such as sound, images, etc. Some only had sound but no images, and some only had static images without dynamic videos, etc.

Multimedia technology has the following main characteristics: (1) Integration can carry out multi-channel unified acquisition, storage, organization and synthesis of information.

Briefly describe the main characteristics of multimedia technology as follows: Interactivity: The interactivity of multimedia technology refers to the ability of users who use multimedia to operate with a variety of information media of the computer, so that multimedia and the way users use information can be more effectively controlled.

How to integrate GIS and video?

This practice is only a preliminary combination of video and three-dimensional platform, which does not give full play to the intuitive characteristics of three-dimensional scenes, and is far from achieving the goal of integrating video position and surrounding three-dimensional information.

First, find the ArcToolBox toolbox and open it, and then click the data management tool, drawing synthesis and fusion buttons below respectively. Finally, you can merge according to your own needs. The details are as follows. Arcgis Fusion Use Tutorial to open the software and find the "ArcToolBox" toolbox to open it.

A projector and a curtain are needed. The same configuration is the same for video fusion. The surveillance camera can be analogy to the projector, and the grid that accepts the video as the texture can be analogy to the curtain.The problem of video fusion is simplified into two parts: (1) calculate the internal and external parameters of the surveillance camera; (2) generate a grid as a curtain.

Why should the channel choose the fully decoupled video fusion system?

1. If you choose a fully decoupled video fusion system, the channel can obtain an autonomous and controllable scheme.The business richness is free, and customers can freely choose algorithms and applications. If the scheme is not completely decoupled, when the scheme manufacturer does not support it, it will not be able to meet the continuous business needs of customers.

2. Improve the content ecosystem: The integration of short videos and live broadcasts can form a more complete content ecosystem, expand the presentation mode and scope of content, provide more diversified, personalized and interactive content, and increase the stickiness and satisfaction of users.

3. Functions and requirements: Clarify your video management needs, such as whether you need to upload, store, edit, share and distribute videos and other functions. Evaluate whether the platform provides the required core functions and can meet the scale and complexity of the target according to the needs.

4. Relying on NetEase's diversified Internet technology and scene accumulation, at the end of 2020, "NetEase Yunxin released a new generation of audio and video technology architecture NE-RTC, including audio and video fusion communication server system, audio and video SDK, audio and video engine, which has achieved upgrades and breakthroughs in audio and video technology from the infrastructure layer.

5. As a thorough transformation, media integration is a systematic transformation of concept, system, mechanism, content, management, operation, etc. It must adopt comprehensive and thorough integration, give full play to the characteristics and advantages of various media, integrate and utilize media resources, and take advantage of each other's strengths.

6. There are two key points to realize omni-channel digital transformation: first, to build an omni-channel system, including system selection, team building, interest model, etc.; second, to use data to support the connection of various links.

Who can help me interpret the meaning of "park video fusion monitoring system capacity expansion"?

FPGA emerged as a semi-customized circuit in the field of specialized integrated circuits (ASIC), which not only solves the shortcomings of customized circuits, but also overcomes the shortcomings of the limited number of circuits of the original programmable devices. FPGA design is not a simple chip research, but mainly uses the model of FPGA to design products in other industries.

How to integrate IP network broadcasting system and IPTV TV system in the scenic spot to provide information and entertainment for tourists...

1. In the public area of the scenic spotThe area is equipped with display screens, such as elevator rooms, lounges, restaurants, etc., and the promotional films, commercials, promotional videos and other contents of the scenic spot are played through the IPTV TV system to attract the attention of tourists and improve the popularity of the scenic spot.

2. First of all, the IP network broadcasting system can transmit music, guides, security tips and other information in the scenic spot to all corners, so that tourists can get better services while enjoying the beautiful scenery. Secondly, scenic spot managers can centrally control the system to realize the functions of volume adjustment, audio switching and so on each partition.

3. Notices and announcements in public areas of the hotel: The IP network broadcasting system can be conveniently used in the lobby, hall, corridor, restaurant and other public areas of the hotel to play announcements, welcome words, emergency notices, activity information, etc.Through the network broadcasting system, the hotel can convey information more conveniently and quickly to improve the efficiency of customer service.

4. Provide interactive and personalized experience: Personalized information and suggestions can be provided by using interactive functions, such as entering the guest's name or room number. In addition, you can also recommend special services, restaurants and activities in the hotel to guests through the ordering service or recommendation function provided by the IPTV system.

5. Support remote access: Support remote access through the IP network broadcasting system, and employees can access the broadcasting system anywhere through the Internet without being limited to the company's internal network.

6. If the user has a computer, you can also surf the Internet while watching TV.
