According to such techniques, the viewport may represent a portion of an image from a multi-directional video to be displayed at the future time, and tile(s) of the image may be identified in which the viewport is estimated to be located. In these techniques, the image data of tile(s) in which the viewport is estimated to be located may be requested at a first service tier, and the other tile in which the viewport is not estimated to be located may be requested at a second service tier, lower than the first service tier.

Abstract: In a method for recovering a lithium precursor from a lithium secondary battery, an electrode powder is prepared from a lithium secondary battery. A calcium compound is mixed with the electrode powder to prepare a cathode active material mixture. The cathode active material mixture is reductively treated to form a preliminary precursor mixture. A lithium precursor is recovered from the preliminary precursor mixture. Accordingly, the lithium precursor is obtained with high purity without a complicated leaching process and an additional process resulting from a wet-based process using an acidic solution.
