I. Overview
Time Interactive Broadband Video on Demand VOD system is built on the Ethernet LAN platform, using full Web interface development and international advanced video encoding and streaming media technology to achieve download while playing, users do not need to wait when on demand, can support thousands of users at the same time On demand.
The VOD system has a very high performance-price ratio, and can be widely used in smart communities, hotels, intranets of enterprises and institutions, school multimedia teaching systems and other fields.
The size of the VOD system is related to the number of users that can be supported. When the number of users is large, the system overhead for load balancing, distributed control, and concurrent flow support is significantly increased, and the performance requirements of the server and network equipment are also relatively high. At the same time, it also puts forward higher requirements for the database management of program management, user management and billing system.
Second, the system structure
Figure 1 is a network topology diagram of an era interactive video-on-demand system with all basic functional modules. The system hardware resources such as servers can be appropriately increased or decreased according to the system scale and investment scale.
The system is mainly composed of video server, WEB server, management system, billing system, authentication server, program production system and program library. Times Interactive Video on Demand System version 3.10 adopts shared disk array storage, which has the characteristics of reliable performance, low cost, easy expansion and easy maintenance.
The VOD system is supported by a database system in the background, which can provide a variety of options, such as MYSQL, MS SQL Server and Oracle, etc. according to the needs of users and the scale of the implementation plan.

Bare aluminium conductors are electrical conductors made from pure aluminium. They are used in various electrical applications, including overhead power transmission and distribution lines.
Bare aluminium conductors have several advantages over other types of conductors. Firstly, aluminium is lighter than copper, which makes it easier to handle and install. This is particularly important for overhead power lines, where the weight of the conductor can have a significant impact on the cost and feasibility of the project.
Secondly, aluminium has a higher conductivity-to-weight ratio than copper. This means that for a given weight, aluminium conductors can carry more current than copper conductors. This makes them more efficient in terms of power transmission.
However, bare aluminium conductors also have some disadvantages. One major drawback is their lower mechanical strength compared to copper conductors. This makes them more susceptible to sagging and stretching under the weight of their own span, especially in hot weather conditions. To address this issue, aluminium conductors are often reinforced with steel strands to improve their mechanical strength.
Another disadvantage is that aluminium has a higher resistance than copper, which can result in higher power losses and voltage drops. To mitigate this, aluminium conductors are typically designed with larger cross-sectional areas compared to copper conductors to compensate for the higher resistance.
Overall, bare aluminium conductors are widely used in electrical power transmission and distribution systems due to their cost-effectiveness, lightweight, and high conductivity-to-weight ratio. However, careful design and installation considerations are necessary to ensure their mechanical strength and minimize power losses.
