作为全球规模最大的消费电子产业盛会,2009年国际消费类电子产品展(CES)在1月8日至11日在美国赌城拉斯维加斯举行。在本次消费产品大展中,我们看到了许许多多的新产品、新技术,除了在08年已经人见人爱的上网本之外,“全高清”、“蓝光”、“高清接口标准”等以高清为话题的产品成为了本次展会上的另外一个亮点。
不过经过多年的努力,高清全面进入家庭的步伐缓慢,蓝光标准虽然早已确立,但是过高的成本是普及的最大障碍,所以我们看到了在不少希望尝鲜的用户,纷纷采用HTPC高清解决方案,作为过渡。而与此同时,一体式电脑在08年年底突然火热起来,更加符合家居摆设和多功能的操作方式,让其有着普通家用PC甚至HTPC都难以比拟的优势。笔者认为一体式电脑更加符合家庭多媒体中心的定位,融合高清解决方案将有助于一体式电脑的普及。
从目前的一体式电脑上看,在硬件上支持高清不成问题,目前软解码(用处理器进行视频解码)渐渐被发烧友认可,兼容性好,支持未来高清编码是其优势,所以配置方面,只对处理器性能有所需求,目前来看,主频在2.4GHz以上的多核处理器都可以完成90%以上的高清解码。
存储方面,效仿HTPC采用硬盘存储方案无可厚非,目前TB级硬盘价格十分低廉,对于目前的高清用户来讲,采用下载或者拷贝等方式进行高清资源共享还是比较节约成本的。此外,一体式电脑可以搭载蓝光光驱,只是目前的蓝光光盘价格还过于昂贵,而且国内资源并不丰富。
如果想做全套的高清多媒体解决方案,仅仅在硬件上支持高清还远远不够。家庭影院系统是视频输出系统,音响系统(包括音箱、功放、独立均衡器等)和媒体播放器等组成。那么笔者大胆猜想AV功放整合到一体式电脑当中,这样以来在电脑端即可完成DTS、True HD等音频的解码,整合多路HDMI输入和输出,使用HDMI的“N进N出”可以让我们的PS3游戏机、高清电视机顶盒、投影机、液晶电视等都可以直接与一体式电脑相连接,使用时可以任意切换,视频音频同步,十分方便。,能否将解码器,甚至
不过,这只是笔者的一个猜想,PC厂商自然无法与专业的解码器、AV功放厂商相比,不过是不是可以只借助这个功能呢,这样以来,家庭影院系统将简化为三部分:投影机(液晶电视)、多声道音箱和一体式PC,无论从易用性还是家居美观上,都是非常不错的。
最后,关于布线,家庭影院布线是个复杂的工程,我们已经看到,像索尼、飞利浦等已经有了无线的影院系统,一体式电脑能否利用无线功能,让其与视频输出设备也做到无线连接呢?无线投影技术目前还不是十分成熟,存在一定的兼容性问题,所以全面无线就目前来讲还并不可行。
一体式电脑有着很多更简易的操作方式,比如说触摸功能,放在家庭影院中,触摸屏可以当做控制台来使用,相对来说,MCE遥控器操作起来可要麻烦许多了。

Full HD solution
As the world's biggest consumer electronics exhibition, 2009 CES was held in Las Vegas in USA from Jan 8 to 11. In this show, we saw many new products, techniques, the products that focus on “HD”, “Blue laser”, “HD port standard” become another lightspot in this exhibition except everyone love’s notebook PC.
However, HD step in to families is slowly even for so many years hard work; blue laser standard was established for a long time, but its high cost became the enormous barriers to popularize. So we saw many early adopters choose HTPC HD solution as a transition. Meanwhile, all in one pc became popular in the end of 2008, which accord with home furnishings and with multifunctional operating mode, has competing advantages to the normal PC and even HTPC. The author thought that all in one PC will meet the position of family media center, fuse with HD solution will help to popularize it.
From the existing all in one PC, we can see that it’s not a problem to support HD. At present, soft decoding gradually accepted by early adopters, with good compatibility, is a advantage to support future HD coding, so for the configuration, only the performance of processor is required. So far, the multi-core processor with basic frequency above 2.4GHz can finish 90% or more HD decoding.
For storage, all in one computer imitate HTPC to use HDD storage solution is not bad, at present, TB level HDD is cheap; so the HD users shared HD resource though down load or copy will be good to reduce the costs. Besides, Blue laser CD-ROM can be install in all in one PC, but the price k is high and have less resource at home.
If you want to make a whole set HD multimedia solution, only your hardware support HD is not enough. Family cinema system is composed by video output system, audio system (including voice box, power amplifier, and independent equalizer) and media player. The author guess that if we can integrate the decoder, even AV power amplifier into all in one PC, the PC terminal can complete the decoding o f DTS, True DH and other audio, integrate multi channel HDMI input and output, we can connect PS3 game player, HD TV set box, projector, LCD TV to all in one PC using the “N in N out” of HDMI
Of course, this is just a guess, PC manufacturers are beyond compare to professional decoder and AV power amplifier manufacturers; or we can just only make use its function, in this way, family cinema system will simplifies into three parts: projector (LCD TV), multichannel voice box and all in one PC. It will be looked very nice not only from the ease of use but also the household beautiful.
At last, about the wiring, cinema wiring is a complicated project; we can see that, like Sony, Philips, they have wireless cinema system. Does all in one PC could use the function of wireless to connect other video output device? Wireless projection technique is not good now, with the problem of the certain compatibility, so total wireless is not feasible at present.
All in one PC with many simple operating modes, like touch function. Touch screen can be used as console in family cinema, in contract, the operating of MCE remote control will get more trouble.
