[00123] In some embodiments, such as in instances in which the apparatus 10 is configured to encode the video bitstream, the apparatus 10 may optionally include a user interface 18 that may, in turn, be in communication with the processing circuitry 12 to provide output to a user, such as by outputting an encoded video bitstream and, in some embodiments, to receive an indication of a user input. As such, the user interface may include a display and, in some embodiments, may also include a keyboard, a mouse, a joystick, a touch screen, touch areas, soft keys, a microphone, a speaker, or other input/output mechanisms. Alternatively or additionally, the processing circuitry may comprise user interface circuitry configured to control at least some functions of one or more user interface elements such as a display and, in some embodiments, a speaker, ringer, microphone and/or the like. The processing circuitry and/or user interface circuitry comprising the processing circuitry may be configured to control one or more functions of one or more user interface elements through computer program instructions (e.g., software and/or firmware) stored on a memory accessible to the processing circuitry (e.g., memory device 14, and/or the like). [00124] Referring now to Figure 2, the operations performed, such as by the apparatus 10 of Figure 1, in order to encode a picture into a coded picture, the coded picture being partitioned to two or more tiles, in accordance with an example embodiment are depicted. As shown in block 20, the apparatus includes means, such as the processing circuitry 12, the communication interface 16 or the like, for receiving a picture. The picture is encoded into a coded picture comprising one or more slices. The picture is partitioned into one or more tiles. The coded picture may be a part of a bitstream. The bitstream may be a bitstream formatted in accordance with HEVC, H.266/VVC, or any file formats described above. [00125] As illustrated in block 22, the apparatus 10 includes means, such as the processing circuitry 12, for encoding, into a slice header of a slice, one or more tile identifiers for any set of the following purposes: Slice location information. A tile identifier is indicative of the tile that comprises a pre-defined or indicated block of the slice, such as the first block of the slice. The block may for example be a coding tree block or a coding tree unit or alike. Horizontal and vertical offset derivation for determining an anchor position for a motion vector. A tile identifier is indicative of a tile position that is used to derive the horizontal and vertical offset. Horizontal and vertical offset derivation for determining an anchor position for obtaining a motion vector candidate from an indicated picture in TMVP or alike operation.
