Broadcast integrated receiver decoders (IRDs) are often at the other end of the video transmission from the encoder to receive and decode the audio/video stream, which is then output for further processing. There are two segments of broadcast IRDs: contribution and distribution, both of which are discussed in the report. Vendors of IRDs may offer products for both segments or only one, which is discussed in the vendor profile section.

The report provides five-year forecasts for ASPs, unit shipments, and revenues for IRDs in each segment by compression type: HD MPEG-2, HD H.264, SD MPEG-2, and SD H.264. These are further broken down by region: Americas, Asia, Europe, and Mid-East/Africa.

高画質番組の増加によって、デコーダ統合型の受信機の出荷数が増加

アリゾナ州スコッツデール、2010年4月8日
デコーダ機能統合型の受信機(IRD)の市場は、今後数年間出荷数を着実に伸ばすものの、平均価格の下落によって、収益は伸び悩むだろうと、米国調査会社インスタット社は報告している。高画質番組の伝送の際に、コンテンツ製作者や番組制作者が伝送に使用する帯域幅を縮小するためにH.264やDVB-S2を使用しており、既存のIRDの置換えがすすんでいる。

「IRDの出荷数は、新しいチャネルの始まりと安定的な5年間の買い換え周期によって、着実に成長している。新しいIRDの需要は、デコードや再コード化の必要というよりも、光ファイバーによる非圧縮動画の伝送と、H.264コンテンツのパススルーの増加のためである」と、インスタット社のアナリストMichelle Abraham氏は語る。

放送事業者向けの品質のデコーダや統合型のデコーダ受信機(IRD)は、スタジオやケーブルテレビ、衛星放送、地上波、通信事業社のテレビサービスなどで、動画や音声の送受信に使用されている。

インスタット社は、下記についても調査した。

• IRDの出荷数は、2014年に21万5000に達するだろう
• 市場の成長は、主にH.264 4:2:2 IRDによるだろう。2012年には、欧州が、伯仲しているアジアと南北アメリカを抜いて、最大の市場となるだろう。
• 3Dコンテンツの登場によって、製作者は可能な限り最高の品質を求めるようになり、IRD市場に大きな影響を与えるだろう。しかし、配信に関してみれば、3Dの初期市場においては、番組制作者には、シングル標準と両方の供給が求められるだろう

インスタット社の調査レポート「世界の放送事業者向けのデコーダとIRD市場調査 ー Worldwide Broadcast Decoders and IRDs」は、世界の放送事業者向けのデコーダとIRD市場を調査した。市場の促進要因と阻害要因、IRDの出荷数、収益、平均価格の圧縮技術毎と地域毎の予測、製品機能、ADI、Adtec Digital、Anevia、AppearTV、ATEME、Caton、Cisco、Envivio、Ericsson (Tandberg)、富士通、Grass Valley、Harmonic、Harris、Motorola、NTT(日本電信電話)、Sencore、Vislink、Vitec、Wegenerなどのベンダについて記載している。

Increased HD Programming Bolsters the Integrated Receiver Decoder Shipments

SCOTTSDALE, Ariz., April 8, 2010 - The integrated receiver decoder (IRD) market will grow unit shipments steadily over the next several years, though revenue will be hampered by falling average selling prices (ASPs), reports In-Stat The need to transmit HD programming is causing replacements of existing IRDs, as content creators and programmers take advantage of H.264 and DVB-S2 to use less bandwidth for transmission.

“IRD unit shipments are experiencing stable growth with new channel launches and dependence on a steady five-year replacement cycle,” says Michelle Abraham, In-Stat analyst. “The need for new IRDs is balanced with growth in transmission of uncompressed video feeds over fiber and the pass-through of H.264 content rather than needing to decode and re-encode.”

Broadcast quality professional decoders and integrated receiver/decoders (IRDs) are used in studios, as well as cable TV, satellite, terrestrial and telco TV infrastructure to receive and decode video and audio streams.

Recent research by In-Stat found the following:

• IRD unit shipments will reach 215,000 units in 2014.
• The large growth opportunity in the contribution market is H.264 4:2:2 IRDs.  By 2012 Europe will take over as the largest geographic segment, exceeding Asia and the Americas which will be nearly equal in size.
• The emergence of 3D content will impact the contribution side of the IRD market, since content producers will want to keep the highest quality for as long as possible. However, on the distribution side, programmers are expected to put both views into a single standard frame in the early years of 3D.

Recent In-Stat research, Worldwide Broadcast Decoders and IRDs (#IN1004664MBI), covers the worldwide market for broadcast decoders and IRDs. It includes:

• Examination of market drivers and barriers.
• Forecasts of IRD unit shipments, revenue, and ASPs by compression type and by region.
• Exploration of product features.
• The vendors discussed in the report include: ADI, Adtec Digital, Anevia, AppearTV, ATEME, Caton, Cisco, Envivio, Ericsson (Tandberg), Fujitsu, Grass Valley, Harmonic, Harris, Motorola, NTT, Sencore, Vislink, Vitec, and Wegener.
