Switched digital video (SDV) is a new video delivery architecture that allows operators to expand their offerings to a virtually unlimited number of broadcast programs while releasing precious bandwidth for the revenue-generating services. SDV improves bandwidth utilization and allows unused bandwidth to be reclaimed when inactive channels are not accessed by the users. In addition, significant cost benefits can be achieved from bandwidth sharing and optimization through high-density video processing.
10. Although multiscreen video connectivity has become widespread, matching the nature of the video content to the screen size is important for the user experience. For example, watching Avatar in the movie theater is a much better experience than watching the same movie on a smartphone. However, watching a 30-minute cartoon or comedy works well for the smartphone. Moreover, mobile users seldom watch full-length movies on 4-inch displays but will watch trailers, music videos, news conferences, and sports highlights.
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). A small buffer size at the client device may lead to high packet losses whereas an overprovisioned buffer size will increase channel change latency, which is undesirable.
