Method for receiving adaptive streaming service

A method for receiving a streaming service for a video content coded in a layered manner, the method being performed at a terminal and comprising:

• (a) sequentially requesting transmissions of chunks of video data for a first layer that are to be stored in an idle space of a first buffer space, where the first buffer space has a first length defined by a total given playing time, and the idle space (i) comprises a first portion of the first buffer space which is not currently being used to store video data and (ii) is absent of a second portion of the first buffer space that is being used to store previously received chunks of video data;
• and
• (b) sequentially requesting transmissions of chunks of video data for a second layer in response to the first buffer space no longer having idle space, where the second layer is of an increased level as compared to a level of the first layer, and the chunks of video data for the second layer are to be stored in an idle space of a second buffer space that is different than the first buffer space, the second buffer space having a second length equal to the first length;
• wherein operations of (a) and (b) are performed during a decoding of video data corresponding to a single video chunk.
