Description
意義深いことに、構成データ4510は、(a)デコーダ側に存在している記憶部の数と、(b)エンコーダ側に存在している又は利用可能である記憶部の数とのうち、いずれか少ない方を定義可能である。これは、選択されたモードは、最終的にはデコーダで実施される必要があるが、関連する記憶部がエンコーダ側にも存在しない限り、モードを符号化において実施することができないためである。符号化データが最終的に既知のデコーダによって復号される場合、そのデコーダの特性は、構成データ4510として提供されることができる。しかし、デコーダが未知である場合、構成データ4510は、任意のデコーダではデコードできない符号化データの生成を許可しないように、(たとえエンコーダ側に1つ以上の記憶部が存在しても)サンプル記憶部がゼロであると定義してもよい。他の例においては、公式規格であれ、専有の規格であれ、あるいは事実上の業界規格であれ、デコーダ規格が(例えば)1つのライン記憶部(又は一般的な数であるn個のライン記憶部)が常に存在しなければならないと指定する場合、未知のデコーダに対しては、n個のライン記憶部がエンコーダ側で利用可能であると仮定して、n個のライン記憶部を指定するように構成データ4510を構成することができる。 Significantly, configuration data 4510 includes ( a ) the number of storage units present at the decoder side and (b ) the number of storage units present or available at the encoder side. whichever is less can be defined . This is because the selected mode ultimately needs to be implemented in the decoder, but the mode cannot be implemented in the encoding unless the associated storage is also present on the encoder side. If the encoded data is ultimately decoded by a known decoder, characteristics of that decoder can be provided as configuration data 4510 . However, if the decoder is unknown, configuration data 4510 does not allow the generation of encoded data that cannot be decoded by any decoder (even if there is more than one store on the encoder side). It may be defined that the part is zero. In another example, a decoder standard, whether official, proprietary, or de facto industry standard, may (for example) support one line store (or n line stores, which is a common number). ) must always be present, then for an unknown decoder, specify n linestores, assuming n linestores are available at the encoder side. Configuration data 4510 can be configured as follows.
