- Abstract
- Usually, a SVC encoding server can provide a single bitstream which has a fixed maximum service layer, to various kinds of devices which have different resources, capacities and performance, simultaneously. Nowadays, as mobile communication technology going on, rapidly, multiple channels are available to single user device in many cases. In this study, we propose new adaptive layer selection algorithm to cope with variation of available channel connections, for providing the maximized quality of video streaming in terms of the consumed power (complexity) of encoding server. To achieve this, the initial negotiation strategy of the connected device is designed based on the performance (decoding and rendering) of it. With initial connection, the proposed SVC encoder changes the proper maximum layers according to the connection status of multiple channels. Through experiments, we verify that the proposed scheme is very effective in terms of the consumed power (complexity) and memory usage of encoding server. © 2013 Springer Science+Business Media.
