The Nineties dawned with a trust that the electronic revolution could notably remodel our conventional thought of towns as locations of trade and undefined. Many estimated that electronic know-how may render towns, or at the very least their economies, out of date. in its place, exactly the contrary occurred. The IT-intensive organizations of the 'new financial system' had to be plugged right into a massive community of expertise, whatever that verified towns like ny and San Francisco supplied in abundance.

Due to the small buffer size, these packets are not available. Hence, the VPLR suffers. 8%. 35 The Access and Home Networks • It is also seen that when there is sufficient buffering space available at the client (receiver), then there is no loss (VPLR = 0). 78 0 To summarize, moderate-sized buffers (greater than the average size of the packets) with an appropriate delivery rate reduce the DJR to a reasonable value 36 The Access and Home Networks while maintaining losslessness of transmission (VPLR = 0).
4. The ABR adaptive streaming technology is normally used in conjunction with loss-free, two-way protocols such as HTTP, which implies all packets sent by the server will eventually be received, even though some of these packets may be retransmitted. In addition, progressive streaming or download using segmented video chunks is used to reduce the traffic load on the network and to provide smoother playback and connection scalability. Why is there a need to reduce the video quality and bit rate when network congestion occurs?
Channels can also be customized to the subscriber’s preference without paying for idle bundled channels. However, the latency for accessing VoD services tends to be higher than broadcast services. In addition, more bandwidth is required since VoD streams are normally unicast. As such, VoD load and utilization need to be monitored and appropriately sized. Bandwidth conservation becomes more critical for such services. Online TV is essentially Internet VoD service, although it can also support live video.
