Description
本非仮出願は、(i)Paul Tweedaleの名において2013年10月18日付けで出願された先行米国仮特許出願第61/892733号「SOFTWARE DEFINED MEDIA PLATFORM」に基づく優先権を主張し、各々は全体として参照により本明細書に組み込まれる。
(i)チャンネルに対して最低サービス品質、すなわち最低数の適応的ビットレート、解像度、フレームレートおよびビットレートをセットする。採集要求が受け入れられると、この最低サービス品質が保証されることになる。
(ii)リソースが許可する場合、より高いサービス品質、すなわち適応的ビットレート数の増加をセットする。
(iii)最終コンテンツを消費しているアクティブクライアントの数に基づいてサービス品質を管理する、エンドユーザしきい値をセットする。典型的には、より多数のアクティブユーザが、統計的に帯域幅がより大きく変動する(たとえばより多くの人がセルラネットワークを介して視聴している、など)という事実により、より適応的なビットレートを要求することになる。
(iv)電子番組ガイド情報および/または他の制御対象外チャンネルに基づくしきい値、すなわちスポーツイベントに関する最低サービス品質。
(v)チャンネルに対する待ち時間しきい値。より短い待ち時間は、生のソースのデコードおよび後続のエンコードを同時に行うための追加のリソースを必要とする可能性がある。
(i)非稼働のTPU、PPU、およびCSUの自動交換。ORMエンティティは稼働中エンティティを監視し、障害を検出した場合、新しいリソースをスピンアップする。
(ii)リソースが制約されている場合、ORMエンティティは他のサービスをその最低サービス品質まで低下させ、結果として障害のあるエンティティを交換するためにリソースを解放することができる。
(iii)シームレスなフェイルオーバーの場合、代替のCSU位置にアップロードするか、またはシームレスに切り替える準備の整った、依然としてアクティブモードにある重複TPU、PPU、およびCSUが作成可能である。
− ビットレートを動的に追加/除去する。
− クラウド記憶へのアップロードを動的に追加/除去する。
− 分析を使用して、(たとえば、視聴者の増加に対処する、品質を向上させるなどのために)追加のビットレートが追加/除去されるべきであるかどうかを判別する。
− 分析を使用して、リソースをシフトする(すなわち、需要ごとに3GビットレートからWi−Fiビットレートへ;多くの需要および帯域幅の可用性に基づき細分性のより高い使用可能ビットレート)。
− より高品質のイベント(たとえば、サンデーナイトゲーム)をスケジューリングする。
− リソース(たとえばTPU/PPU)をクラウド内に配置する。
− 高速ウォームスタートアップ(すなわち、低ビットトランスコードは実行しているが、セグメント化/アップロードは発生していない)。
− 冗長性(たとえば、上昇可能な実行中の低ビットレートのバックアップチャンネルを有するなど)。
− リソースを割り振り、以下の例を含む様々な入力に基づいて設定する。(1)電子番組ガイド(EPG)からのプログラミング情報、(2)位置、サービスレベル契約(SLA)などのユーザプロファイル情報、(3)性能の変化(たとえば電力管理のための内部調整)に関する処理ユニットからの情報。
− トランスコーディング機能に対してI/Oハードウェア抽象化を提供する。
