Description
0fpsで動作し、IBBPBBPBBPBBPBBのGOP構造(周期N=15フレーム)が使用されると仮定する。Bピクチャの順次除去と、その後に続くPピクチャの除去により、30fps(すべてのピクチャタイプが含まれる)、10(IおよびPのみ)、および2fps(Iのみ)の合計3つの時間解像度を導出することが可能である。PピクチャのコーディングがBピクチャに依拠せず、同様にIピクチャのコーディングが他のPピクチャまたはBピクチャに依拠しないようにMPEG-2 Main Profileコーデックが設計されるので、順次除去プロセスの結果、復号化可能ビットストリームが得られる。以下では、時間スケーラビリティ機能を有する単層コーデックが、スケーラブルビデオコーディングの特別なケースであるとみなされ、したがって明示的な指示がない限り、スケーラブルビデオコーディングという用語に含まれる。
例えばSinger,D.、「A general mechanism for RTP Header Extensions」、draft-ietf-avt-rtp-hdrext-01(進行中の研究)、2006年2月で定義された、このヘッダ拡張要素について取り決められたローカル識別子。
ヘッダバイト(IDおよびlen)をカウントしない、このヘッダ拡張要素のデータバイトの長さから1を引いたもの。これは、第2ワード(置換される範囲)が存在する場合に値6を有し、第2ワードが存在しない場合に2を有する。したがって、この値は2または6でなければならない。
このヘッダ拡張要素を含むパケットがRシーケンス番号RSEQを有する系列SER中のRパケットであることを示すビット。このビットがセットされていない場合、その代わりに、ヘッダ拡張要素が、メディアストリームの系列SER中の最新のRパケットがRシーケンス番号RSEQを有していたことを示す。このビットがセットされていない場合、置換される範囲が存在すべきではなく(すなわち、lenフィールドは2であるべきである)、存在する場合、無視されなければならない。
予約済みビット。これは送信時に0にセットされなければならず、受信時には無視される。
このヘッダ拡張要素で記述されているRパケットの系列の識別子。メディアエンコーダが単一の系列のRパケットを記述している場合、これは値0を有するべきである。例えば、図13に示されるスケーラブルビデオピクチャコーディング構造を使用して、Lパケット(ベース空間拡張層、全スレッド)は、例えば0にセットされたSERを有することになり、Sパケット(空間拡張層、全スレッド)は、1にセットされたSERを有することになる。
系列SER内のこのRパケットの番号を示す符号なしシーケンス番号。この値は、所与の系列で送られるRパケットごとに1だけ増分される(modulo 2^16)。別々のシーケンスについてのRSEQ値は独立である。
modulo 2^16で計算される、このRパケットによって置換される、包含的な、最初のRパケットのRシーケンス番号(この値は剰余演算を使用するので、置換される範囲の終わりより前のすべてのRパケットが置換されていることを示すために、SUPERSEDE_STARTについて値RSEQ+1を使用することができる)。このフィールドは任意選択であり、len=6であるときにのみ存在する。
modulo 2^16で計算される、このRパケットによって置換される、包含的な、最後のRパケットのRシーケンス番号。この値は、閉じた範囲[SUPERSEDE_START..RSEQ]modulo 2^16内になければならない。このフィールドは任意選択であり、len=6であるときにのみ存在する。
RSEQフィールドは受信側が受信していないRSEQ値を示す。
このヘッダ拡張要素によってRパケットのどのシーケンスが紛失していると記述されているかの識別子。
BLRは、RSEQによって示されるRTPパケットの直後の12個のRパケットのいずれかの紛失を報告することを可能にする。BLPの最下位ビットをビット1と表し、BLPの最上位ビットをビット12と表すと、受信側が系列SER(modulo 2^16)中のRパケット番号(RSEQ+i)を受信していない場合にビットマスクのビットiが1にセットされ、このパケットが紛失していることを示す。そうでない場合、ビットiは0にセットされる。Rパケットのビットマスクが0にセットされていたからといって、送信側は、受信側がRパケットを受信したことを仮定してはならないことに留意されたい。例えば、RSEQに対応するパケットと、シーケンス中の後に続くRパケットとが紛失した場合、BLRの最下位ビットが1にセットされる。しかし、送信側は、BLRのビット2から15が0であるというだけでの理由でパケットRSEQ+2からRSEQ+16が受信されたことを推測することはできず、すべての送信側が認識することは、受信側がこの時に紛失したと送信側に報告していないことである。
そうでない場合、すなわち現ピクチャがIDRピクチャではない場合、PrevTL0FrameIdxが、復号化順でTが0に等しい最新のピクチャのFI値に等しいとする。現ピクチャに関するFIの値は、(PrevTL0FrameIdx+1)%256に等しくなる。数字256は、FIフィールド(最大値+1)のダイナミックレンジを表し、異なるFIフィールド長では値2^(ビット単位のFI長)に調節されるべきである。
