enabled tile set identifies one or more dependent tiles from the one or more tiles, wherein the one or more dependent tiles are dependent on another dependent tile within a coded picture or form a logical atomic unit with another dependent tile. As illustrated in block 74, the decoder may further include means for decoding the bitstream according to the indication of the in- picture-prediction-enabled tile set. [00197] Likewise, where the example embodiments have been described with reference to a decoder, it needs to be understood that the encoder may have structure and/or computer program for generating the bitstream to be decoded by the decoder. [00198] In the above, where the example embodiments have been described with reference to syntax and semantics, it needs to be understood that the embodiments likewise cover an encoder that outputs a bitstream portion according to the syntax and semantics. Likewise, the embodiments likewise cover a decoder that decodes a bitstream portion according to the syntax and semantics. [00199] The embodiments of the invention described above describe the codec in terms of separate encoder and decoder apparatus in order to assist the understanding of the processes involved. However, it would be appreciated that the apparatus, structures and operations may be implemented as a single encoder-decoder apparatus/structure/operation. Furthermore, it is possible that the coder and decoder may share some or all common elements. [00200] Although the above examples describe embodiments of the invention operating within a codec within an apparatus, it would be appreciated that the invention as defined in the claims may be implemented as part of any video codec. Thus, for example, embodiments of the invention may be implemented in a video codec which may implement video coding over fixed or wired communication paths. [00201] Many modifications and other embodiments of the inventions set forth herein will come to mind to one skilled in the art to which these inventions pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Moreover, although the foregoing descriptions and the associated drawings describe example embodiments in the context of certain example combinations of elements and/or functions, it should be appreciated that different combinations of elements and/or functions may be provided by alternative embodiments without departing from the scope of the appended claims. In this regard, for example, different combinations of elements and/or functions than those explicitly described above are also contemplated as may be set forth in some of the appended claims. Although specific
