Chapter 4 Using IP/TV Viewer

Playing a Program

Up to four viewer windows that are open at the same time are supported. However, IP/TV does not limit the number of viewer windows you can open at one time. If you have subscribed to more than four programs that run simultaneously, you will only receive four programs at one time. When one program ends and you close that viewer window, another program will begin playing.

Note Displaying multiple IP/TV viewer windows may result in poor video performance, especially on less powerful computers. If you want the best possible quality, stop playing all IP/TV programs you are not watching and close other applications that you are not using.

IP/TV Viewer performs best on faster machines, and when receiving data through less congested networks. When these conditions are not met, IP/TV provides lower-quality reception.

If the video you are watching appears jerky and you notice that your computer has a lot of disk activity, your computer may be running low on memory.

Here are a few suggestions on how to get the best performance from IP/TV Viewer on your computer:

Close applications you are not using, especially applications that require significant bandwidth on your local network.

IP/TV supports multiple windows; however, you may want to close these windows rather than minimize them to receive multimedia streams.

Trade sound quality for better video quality.

If you only want to listen to a program while you are working in another program, you may want to disable the video. See the “Advanced Topics” section on page 4-35.

If the program is an MBone session, the cause of poor reception might be external to your corporate network, and thus beyond the ability of your system administrator or network manager to correct. Consult the contact person on the MBone program contact list regarding the quality of the MBone program.

Use the Pause button if video is not needed.

OL-3995-01 specifications

Cisco Systems OL-3995-01 refers to the Cisco Certified Network Associate (CCNA) certification exam, which serves as a fundamental stepping stone for IT professionals and network engineers looking to establish a robust foundation in networking technologies. The CCNA certification focuses on a wide range of essential skills and concepts that are vital in the networking domain.

One of the main features of the Cisco OL-3995-01 exam is its emphasis on network fundamentals. This includes an understanding of network types, models, and protocols. Candidates learn about the OSI model, IP addressing, and subnetting, which are critical for managing and troubleshooting networks. Additionally, the exam covers LAN and WAN technologies, providing insights into how data is transmitted over different types of networks.

Another key aspect of the OL-3995-01 exam is security fundamentals. With the increasing importance of cybersecurity, this certification prepares candidates to implement basic security measures and understand the principles of network security. Topics include securing network devices, managing access control lists, and understanding common security threats, which are essential for protecting organizational data and infrastructure.

The exam also explores automation and programmability, reflecting the evolving nature of networking in modern IT environments. Cisco emphasizes the significance of software-defined networking (SDN) and network automation tools that facilitate network management and efficiency. This prepares candidates for environments where manual configurations are being replaced by automated processes.

Moreover, the OL-3995-01 exam includes practical knowledge about IP services such as DHCP, NAT, and DNS, which are crucial for any network operation. Students learn how these services support network functionality and enhance user experience.

In terms of characteristics, the Cisco CCNA certification is globally recognized, making it a valuable credential in the IT job market. Cisco's reputation as a leader in networking solutions adds credibility to the certification, signaling to employers that the certified individual possesses a solid understanding of networking basics.

In summary, the Cisco Systems OL-3995-01 (CCNA) certification exam comprehensively covers networking fundamentals, security, automation, and IP services. By equipping professionals with essential skills and knowledge, it prepares them for a successful career in network administration and engineering. This certification not only enhances career prospects but also lays the groundwork for further specialization in advanced networking technologies.
