DAB標準晶片在行動電視手機中略佔上風
上網時間：2005年11月09日
| 市場研究公司Eureca Research日前發表一份報告指出，到2010年預計有2,950萬部電視手機將採用數位音訊廣播(Digital Audio Broadcasting，DAB)標準，另外還將有2,050萬個人音樂播放器、可攜視訊播放器和行動PC裝備DAB晶片組。 如同多數新興業務一般，行動多媒體廣播服務(mobile multimedia broadcast services，MMBS)向人們提供了一系列不同的平台，從許多數位射頻和自有的衛星多媒體標準，到DVB-H和ISDB-T等採用電視的標準，不一而足。Eureca Research指稱，Eureka-147 DAB與其它平台相較，令人注目，而且風險較低。 「隨著在非常重要的VHF頻帶上有更多的頻譜可供使用，我預計未來12至18個月，市場對採用DAB的數位射頻的接受度將會顯著增加。」Eureca的研究主管Gareth Owen表示。「採納了AAC+編解碼技術的新的DAB v2標準的推出，應該會消除人們對於Eureka-147標準的頻譜效率的擔憂。」 Eureca Research預測，到2010年底，支援廣播的手機將從2005年底的45萬部左右成長到1.555億部，複合年增率為104.8%。其中，採用 DAB標準的手機將達2,950萬部，占全球市場的19%。這意味著，元件製造商在未來五年內累計市場機會達101億部(約176億美元) 採用Eureka-147 DAB標準的商業行動電視服務將於2006年初在英國和韓國啟動。中國大陸等其它亞洲國家以及一些歐洲國家對它的興趣增強，意味著如果能夠吸引到手機供應 商的更廣泛支援，採用Eureka-147的技術可能成為與DVB-H抗衡的第二個全球標準。 Eureca Research預測，DAB-IP和T-DMB服務將引領歐洲MMBS的發展，初期將使用現有DAB網路的共享容量，2006和2007年將出現專門針 對MMBS的新的DAB網路。在中長期來看，地面MMBS市場將由眾多容量較小的DAB網路組成，每個國家有一或兩個容量較高的DVB-H網路。個人音樂 播放器、可攜視訊播放器和行動PC等許多非手機消費產品，也將支援行動廣播技術。(原文連結處：DAB chip sets seen gaining in mobile TV market) (Colin Holland) |

DAB chip sets seen gaining in mobile TV market

Developments in broadcast technologies mean that it is now possible to deliver TV and a range of multimedia content reliably to small hand-held devices such as mobile phones. This has given rise to a new business — mobile multimedia broadcast services (MMBS) — which will bring about the convergence of the mobile and broadcast industries.
As with most emerging businesses, there is a bewildering array of different technology platforms to consider, ranging from a number of digital radio and proprietary satellite multimedia standards to TV-based standards such as DVB-H and ISDB-T.
Eureca Research (Bangor, U.K.) predicts the Eureka-147 DAB standard offers an interesting, lower-risk alternative to most other technology platforms. "I expect to see a significant acceleration in the take-up of digital radio via DAB during the next 12-18 months as more spectrum becomes available in the all-important VHF band," said Gareth Owen, research director at Eureca. "Concerns about the spectrum efficiency of the Eureka-147 standard should be dispelled with the launch of the new DAB v2 standard which incorporates AAC+ codec technology."
Eureca Research forecasts that the installed base of broadcast-enabled mobile phones will increase from approximately 450,000 at the end of 2005 to 155.5 million units at the end of 2010, representing a compound annual growth rate of 104.8 percent.
Mobile phones using the DAB standard will account for 29.5 million units, or 19 percent of the total global market. That represents a cumulative market opportunity of 10.1 billion (about $17.6 billion) for device manufacturers over the next five years.
With mobile TV emerging, Eureca predicts that many countries will use much of the new spectrum for mobile TV-type services, and that the present 20 percent data limit on DAB multiplexes will be relaxed in most countries. That could lead to more capacity.
Commercial mobile TV services based on the Eureka-147 DAB standard will commence in the U.K. and South Korea in early 2006. Increasing interest in other parts of Asia, particularly China, and in several European countries, means that Eureka-147-based technology could become a second global standard rivaling DVB-H, providing it can attract wider support amongst handset vendors.
Eureca Research predicts that MMBS growth in Europe will be led by DAB-IP and T-DMB services, initially using shared capacity on existing DAB networks, with new DAB networks dedicated to MMBS becoming available in 2006 and 2007. In the medium to long term, the terrestrial MMBS landscape will consist of numerous smaller capacity DAB networks (many offering free-to-air services) and one or possibly two higher capacity DVB-H networks per country.
Mobile broadcast technologies will also be incorporated into a number of non-phone consumer devices such as personal music players, portable video players and mobile PCs.
"All new personal music players will be wirelessly-enabled by the end of 2010, and the majority of these will be equipped with DAB technology" said Owen. The first personal music player capable of downloading music from a DAB broadcast stream will be launched in early 2006. "Radio broadcasters are well positioned to capitalize on the boom in music downloads and this could become a significant market opportunity for the radio industry."
The recent launch of Apple's video iPod could kick-start the market for portable video players and video download services. PVR vendors are preparing to launch a range of portable players which can be connected to a PVR via a USB link, and which would enable pay-TV subscribers to download stored content to a portable device for viewing on-the-go. These devices will increasingly become equipped with a variety of MMBS technologies such as DAB-IP/T-DMB and DVB-H.
The report also provides a detailed analysis of spectrum availability in Europe and overviews of MMBS trials and commercial services.
A key feature of the report is a 35-page review of the global roll-out of digital radio — both terrestrial and satellite — detailing how existing digital radio networks are being used to deliver multimedia content, and how digital radio broadcasting can be used to offer mobile TV and music downloads services with minimal investment in network infrastructure.
Eureca Research said it conducted almost 100 interviews for the study, including interviews with regulators in 17 European countries.
The report was issued the same week that Nokia introduced its N92 mobile-TV phone.
