四通道D1单芯片编解码器问世，DSP供应商面临挑战

基于安全方面的考虑，全球数字视频安防市场自911后出现了爆炸性的增长。从而推动了相关压缩芯片市场快速发展，并加剧了相关芯片供应商之间的竞争。在这个领域，供应商名单中不仅有TI和NXP这样以DSP方案为主的传统半导体大厂，也有PentaMicro、Mobiligen等新兴的以ASIC方案为主的其他竞争对手。后者中需要特别提到的还有Vweb公司，凭借其全球第一款四通道D1单芯片编解码器VW5010，这家公司在刚刚举行的CES 2008上备受瞩目。

Based on safety considerations, the global digital video security market since Sept. 11 after the explosive growth. So as to promote the relevant compression chip market developed rapidly, and exacerbated by chip-related competition among suppliers. In this area, the list of suppliers not only to TI DSP and NXP this programme consisting mainly of traditional semiconductor maker, also PentaMicro, Mobiligen and other emerging ASIC programme mainly to the other competitors. The latter in particular reference to the need to have Vweb Corporation, with its world's first four-channel D1 single-chip codec VW5010, this company has just held in the CES 2008, became the focus of attention.

尽管原定在CES 2008上发布这款号称能为多通道数字视频录像机市场提供最佳性价比的新品。不过2008年初，在她最近一次的中国之行中，Vweb首席执行官陈秀蓉已经让其主要的中国客户提前领略到了VW5010的强大性能。很显然，在取得GE、Everfocus、中兴、 Handsome、Siemens、三星、SECOM/AMIT等客户后，这家已经在美国市场取得成功的编解码器供应商正在将其业务重点向东方市场转移。

Although originally scheduled to unveil the CES 2008 on claims for multi-channel digital video recorder market provides the best cost-effective new products. But early in 2008, in her last trip to China, Vweb CEO Hsiu-Jung Chen has been the main customers in China so early taste of the strong performance of the VW5010. It is clear that in a GE, Everfocus, ZTE, Handsome, Siemens, Samsung, SECOM / AMIT, and other customers, this has been in the U.S. market for the success of the codec providers are its business focus to the Eastern transfer market.
 

“VW5010是一款实时的、与MPEG标准完全兼容的高密度四路D1或16路CIF格式MEPG-1, 2, 4音视频/系统编解码芯片。”陈秀蓉介绍。据她出示的资料，这芯片支持时分复用(TDM)模式，可进行每秒7.5帧的16路D1格式NTSC图像编码或者每秒6.25帧的16路D1格式PAL图像编码。能够接收未经压缩的ITU-R.BT-656视频和I2S音频信号。其中，视频信号将被压缩成MEPG-1, 2, 4格式，而音频信号则可被转成MPEG-Layer 1, 2、MP3、AAC、AC-3、G.711、G.726、G.729等各种格式。在系统层，VW5010将音频与视频信号结合在一起形成一个传输流和程序流。编码器的输入接口包括：四个8位的 ITU-R.BT-656口(视频)、四个I2S口(主机或从机模式)。输出则为一个33MHz的32位PCI接口。VW5010编码端还提供8位元OSD的支持，以方便厂商轻松实现识别通道号码、时间、地点或密码遮盖功能。

"VW5010 is a real-time, fully compatible with the MPEG standard high-density four-way D1 or 16 CIF format MEPG-1, 2, 4 audio and video / system codec chip." Hsiu-Jung Chen introduced. According to her to produce the information, this chip supports time division multiplexing (TDM) mode, can be 7.5 per second of the 16 D1 NTSC format image coding, or 6.25 per second of the 16 D1 PAL format image coding. Capable of receiving uncompressed ITU-R.BT-656 video and audio signals I2S. The video signal will be compressed into MEPG-1, 2, 4 format, and audio signals can be transformed into MPEG-Layer 1, 2, MP3, AAC, AC-3, G.711, G.726, G. 729, and other formats. In the system layer, VW5010 audio and video signals will be combined to form a transport stream flow and procedures. Encoder input interfaces include: four eight of the ITU-R.BT-656 I (video), four I2S I (host or slave mode). Output for a 33 MHz 32-bit PCI interface. VW5010 encoder-8-bit OSD also provided support to facilitate easy identification manufacturers access number, time, place or password cover features.

来看解码方面。这款单芯片的四路D1编解码器不仅能够接收MPEG-1, 2, 4或者H.263格式的视频比特流输入，将其转成ITUR.BT-656视频格式。也可将MPEG-1 Layer 1, Layer 2、MP3、AAC、AC-3、G.711、G.726或者G.729的音频比特流输入解压缩后从IS2接口输出。与编码器相反，设计人员为其解码器配备了四个8位 ITU-R.BT-656视频输出口，四个I2S(仅有主机模式)音频输出口。此外，还包括一个工作在33MHz的32位PCI接口。解码器输入也采用了同样规格的PCI接口。VW5010解码端支持2个OSD平面，包括32位高解析度色彩和8位α－blending 功能。

Aspects of the decoder. The single-chip quad D1 codec is not only capable of receiving MPEG-1, 2, 4 or H.263 format video bit stream input, will convert it to ITUR.BT-656 video formats. Can also be MPEG-1 Layer 1, Layer 2, MP3, AAC, AC-3, G.711, G.726 or G.729 audio bit streams of the compressed input from IS2 interface output. And encoder On the contrary, the design staff for their decoders equipped with four eight ITU-R.BT-656 video output, four I2S (only host mode) audio output. In addition, the work also includes a 33 MHz 32-bit PCI interface. Enter decoder also used the same specifications of the PCI interface. VW5010 decoder support two OSD plane, including 32 high-resolution color and eight α-blending functions.

在过去数年中，以NXP公司的PNX1300、PNX1500以及TI公司的DM64X系列为代表的DSP方案一直处于绝对支配的地位。原因有四点：首先，采用DSP平台，工程师具有更大的开发自由度，他们能够根据自身应用的不同而选择不同的产品，以便达到最佳的性能和最低的成本，并可满足不断变化的市场所带来的各种新需求；其次，DSP能够同时处理多路音视频信号，并可提供视频滤波、解交错、OSD甚至网络接口、IDE接口等各种功能，有利于大幅降低成本；再者，DSP平台能够实现快速的技术更新和产品换代。

In the past few years, to NXP's PNX1300, PNX1500, as well as TI's DM64X series as the representative of the DSP programme has been absolutely dominant position. 4:00 reasons: First, the use of DSP platform, engineers have developed a greater degree of freedom, they can in accordance with their different applications and different products, in order to achieve the best performance and the lowest cost and meet the ever-changing Market brought about by new demands and secondly, DSP can handle more way audio and video signal, and video filtering, de-interlacing, OSD or network interface, IDE interface, and other functions, to substantially reduce costs In addition, DSP platform to achieve rapid technological updates and product transformation.

不过，在以Vweb、PentaMicro、Mobiligen为代表的ASIC厂商的推动下，DSP的优势堡垒正在被迅速瓦解。这些不断涌现的新型ASIC器件不仅具有强大的MPEG编解码能力，可将视频比特流转成各种MPEG格式，也可将各种格式的视频信号进行解码，同时还具有完备的音频信号处理能力。而丰富的接口也令其在同DSP的竞争中渐渐显露头角。这令ASIC供应商开始对其未来感到乐观。陈秀蓉甚至表示，VW5010的出现将很可能改变中国的安防监控数字视频处理市场的现有格局。

However, in order to Vweb, PentaMicro, Mobiligen as the representative of the promotion of the ASIC vendor, DSP bastion of the advantages of being rapidly disintegrated. These are emerging new ASIC devices not only has a great ability to MPEG codec, video-bit transfer into a variety of MPEG formats, can also be a variety of formats to decode the video signal, and also offers a complete audio signal processing capability. And also its rich interface with the DSP in the competition gradually revealed Tau Kok. This ASIC suppliers are optimistic about its future began. Hsiu-Jung Chen even said that, VW5010 the emergence of China is likely to change in the security monitoring digital video processing of the existing market structure.

“VW5010是专为多路视频安防和数字家庭路由应用而设计的。”陈秀蓉称。她表示，尽管目前中国大陆90%需要CIF处理能力的市场都是被DSP方案所占据，但漫长的开发周期和高昂的成本却一直为工程师所诟病。“相比之下，采用VW5010来实现最终可节约近一半左右的成本。”她以TI的64系列DSP(TMS320DM642)为例，指出其目前最多只能实现两路D1编解码处理能力，价格约为25美金左右，每通道成本超过10美金。“相比之下，四通道D1的VW5010有望实现20美金的售价，每通道成本可低至5美金左右。”

"VW5010 is designed for multi-channel video security and digital home designed for routing applications." Hsiu-Jung Chen said. She said that despite the current 90 percent of mainland China need to CIF handling capacity of the market are occupied by the DSP programme, but the long development cycle and the high cost has been criticized by engineers. "In contrast, VW5010 used to achieve the ultimate savings of about half the cost." She TI's 64 Series DSP (TMS320DM642) as an example, that can only achieve its current maximum of two road D1 codec processing capability, about the price For around 25 U.S. dollars, the cost per channel over 10 U.S. dollars. "By contrast, four-channel D1 of the VW5010 is expected to realize the price of 20 dollars per channel cost can be as low as about 5 dollars."

不过，成本劣势只是陈秀蓉所认为的DSP方案众多软肋中的一个。“在其他关键技术参数指标上DSP方案也无法同Vweb的ASIC方案相比。”陈秀蓉说，“首先，DSP的音、视频同步能力还相对较弱。其次，DSP的功耗也相对较高。以DM642为例，其工作频率为600MHz上，而Vweb的ASIC其工作频率只有162MHz。”此外，她还指出，DSP的延迟时间为5～7秒，而ASIC的的延迟时间仅有0.2秒。“最后，ASIC方案采用了许多专有MPEG-4处理技术，通用性较强的DSP很显然在这方面还无法与其比拟。”她说。
 

However, the cost disadvantage is that the DSP Hsiu-Jung Chen by numerous weaknesses in the programme one. "In other key indicators on the technical parameters of the programme can not be with the DSP Vweb the programme compared to ASIC." Hsiu-Jung Chen said, "First of all, DSP audio, video synchronization capacity is comparatively weak. Secondly, DSP power consumption is also relatively High. DM642 as an example to its work on the frequency of 600 MHz, while the ASIC Vweb frequency of its work only 162 MHz. "In addition, she also pointed out that, DSP the delay time for five to seven seconds, and the delay time of the ASIC only 0.2 Seconds. "Finally, ASIC programme using a number of proprietary MPEG-4 technology, GM of the DSP is obviously stronger in this area can not compare with the." She said.

Vweb的第二款产品VW2010于2002年10月问世，这令其成为全球第一家推出MPEG-4 D1单芯片音视频编解码器的供应商。据称，目前全球有300多家终端厂商正在采用Vweb的芯片进行量产。以GE为例，该公司的12款数字视频安防监控系统全都采用了Vweb的芯片——SymDec 16 DVR是其中的典型代表：这款采用了16个VW2010的终端能够实时的在所有16个通道上录制和同时解压16个D1精度的视频信号，拥有简单易用的接口；并且配置了DVD烧录机、3TB的内部存储器以及闪存和硬盘USB接口；它还是一款拥有4路IP摄像头码流的混合式DVR。

Vweb VW2010 products in the 2 October 2002 come out, make it the world's first company to launch MPEG-4 D1 single-chip audio and video codec suppliers. It is said that at present there are more than 300 global manufacturers are using Vweb terminal chip for mass production. To GE as an example, 12, of the company's digital video security monitoring system are used Vweb chips - SymDec 16 DVR is one of the typical representative: The use of the 16 VW2010 end to the real-time access in all 16 At the same time on the record and to extract the 16 D1 accuracy of the video signal, with easy-to-use interface and configuration of the DVD burner, 3 TB of internal memory and flash memory drives and USB interface; it still has a four-way IP video cameras stream the hybrid DVR.


Handsome的8通道工业DVR校园安防嵌入式系统也采用了8个VW2010。而NTT East和NTT West已经在日本运行了三年的Plala.TV视频点播服务中也采用了VW2010。VW2010同样在中国市场取得了成功。IBM就在它的双模(有线与IP)机顶盒中使用了这款芯片，后者已经被中国网通和中国电信应用在视频点播系统上。此外，在法国高铁监控、韩国日本的影音对讲家庭监控、中国长江航运的监控、上海地铁、洋山深水港等的数字视频安防监控系统所使用的编解码器上，都出现了Vweb的名字。

Handsome 8 channel DVR industrial campus security embedded systems are also used eight VW2010. And NTT East and NTT West in Japan has run a three-year Plala.TV video-on-demand services were used in VW2010. VW2010 the same in the Chinese market has been successful. IBM in its dual-mode (Cable and IP) set-top boxes used in the chip, which has been China Netcom and China Telecom used in video-on-demand system. In addition, monitoring the high-speed railway in France, Japan, South Korea-speaking family video monitoring, maritime surveillance China's Yangtze River, Shanghai Metro, the Yangshan deep-water port, such as digital video security monitoring system used by the codec, have emerged Vweb's name.


VW2010的出货量已经超过200万片。陈秀蓉表示，随着成本的进一步降低，VW5010将比VW2010取得更大的成功。她相信，随着中国“平安城市”、“全球眼”以及“教育监控”市场的启动，对于多路D1编解码器市场的海量需求将会为以Vweb为代表的ASIC方案供应商带来巨大的增长机会。一个最近的例子是，在中国的“校园监控”项目上，包括恒生在内的两家厂商以Vweb方案为主的8路工业DVR在11家提供不同方案的中脱颖而出，顺利中标

VW2010 the volume has more than 2 million. Hsiu-Jung Chen said that with the cost of further reducing, VW5010 than VW2010 achieve even greater success. She believed that, as China's "Green City", "Global Eye" and "education monitoring" the market started, the multi-channel D1 codecs the mass market will demand to Vweb as the representative of ASIC solution providers bring enormous Opportunities for growth. A recent example is that in China "campus monitoring" projects, including the Hang Seng, the two companies to Vweb programme consisting mainly of 8 industrial DVR in 11 different programmes stand out, smooth the successful bidder
