如何让IPTV的产业链顺畅连接?

内容及增值服务提供商无疑可以从IPTV中获得长期巨大经济利益,盛大希望能够通过机顶盒将游戏固化进服务,中央台下属的中央数字电视传媒有限公司、中视网络公司也希望依托中央台强大的频道资源,在IPTV发展中抢到自己的蛋糕,虽然目前中视网络公司提供的IPTV内容与央视的免费频道没有区别,但是还是能够满足一些有线电视不能覆盖地区的需求。由于广电的背景,中视网络、中视传媒等公司有先天的竞争优势,但是面对盛大这种强大的竞争对手,或者和纵连横,或者拼个你死我活,鹿死谁手只有大家拭目以待了。

  另外,CDN跟P2P有一个非常好的结合。我们使用P2P和CDN结合以后,可以把一些节点作为P2P重要语言,所有用户可以从不同语言进行下载。这样的好处是有效保证服务质量,可以建立一个可管理、可运营的P2P网络。这项服务对于大的软件升级包、流媒体的网站以及需要下载游戏客户端的网站都会有极大的吸引力。我们在设计P2P、CDN应用的时候,我们使用了一个专门的协议,是基于UDP的协议进行传输,实际上我们都知道P2P有防止堵塞的机制,这些机制在一定程度上保证了它的可靠性,另外一方面又制约了TCP的传输效率,有一个研究数据表明,在网络当中延迟为20%,最高TCP吞吐量低于300Kbps,从而导致效率的下降,使用UDP以后,可以有效提高传输速度5-100倍。

灯少看厂家—思华

看着思华的介绍,感觉思华就是一个为着IPTV而成长的公司,而思华能如此迅猛的发展壮大,我觉得是得益于领导层的战略眼光。思华的发展是典型的资本经营、技术收购的过程,他的企业核心竞争力都是通过资本收购实现的。斥资收购优度、英卓、中广视讯是思华最划算,最有远见的三笔投资,也为他投身IPTV的运营奠定了扎实的基础和坚强的后盾。甚至可以说,没有这三项投资,也就不会有思华在IPTV领域的风光

不久后,我进一步意识到商业本身可以充满创意。出版杂志,是在创造一份具有原创性,深入人心,持久,充满理想,并且能达到一些有用目的的东西;最重要的是,创造你所引以为傲的成果--这一直是我的商业哲学。我从未仅仅为了赚钱而去从事某项商业活动。如果仅仅为了赚钱,我劝你最好别做。做商业必须有趣,还能激发你自身创造力

摘自《布兰森自传》

2005年12月13日

刚和女友通了电话,我们虽远隔千里,但那份爱恋却没有丝毫的衰减。我们热烈的吻对方,爱对方。相互的拥抱。我知道她是我会一辈子牵挂,一辈子疼爱的人。我希望我们会永远幸福,快乐,就像现在一样,而且感情会日积月累,象酒一样纯厚。

我最需要做的是物质的积累,没有坚实的经济基础就不可能有幸福的生活。我应该让我的家人,让我爱的人过得更好。至少要有幸福生活所需得物质保障,这是我首先要努力的。

已经忘了是谁把《引爆流行》推荐给我的。今天终于有空开始读他,很快就对他的观点产生了一种认同感。最近蓬勃发展的p2p流媒体,还有我很欣赏的一位blogger,他们的发展和膨胀轨迹竟然都暗合这本书的观点。一种思想,行为,产品为什么会向传染病一样迅速的传播开来?

一位现在相当有名的blogger,  多年不辍坚持写blog, 但不久之前他的影响力还仅仅局限在工作和生活的圈子里。似乎一直在积累,但距“引爆点”还有那么一层纸。这个时候外部的条件的发生了一些变化,他被一家颇有名气的公司相中负责一个创业项目。借力于这个平台的,又结识了几位在这个圈子力颇有影响力的人物,于是乎他的名字一时间在圈子内外光为流传,blog也是洛阳纸贵。

这个身边的例子,与《引爆流行》中提到的流行潮的三条法则简直是珠联璧合。个别人物法则,附着力法则,环境威力法则

几位大牛的推介,就是那颗引爆流行的火柴,符合个别人物法则:公众人物,某个领域的重量级人物常常可以引导人们的喜好,品味。

而这位blogger多年的积累,写的文章的确颇有洞察力,可谓掷地有声,这就是附着力法则,事物之所以流行必有其独到之处,打动人心之处。要在人的脑海里产生冲击。

再说到环境威力法则,环境变化了,新的公司,有吸引力的项目,有了可以支配的资源。使之在这个圈子里有了一个着力点。你是谁,在做什么和你是不是有见解有品位同样的重要。

哈哈,流行貌似神秘,其实还是有规律可循的。《引爆流行》给我们呈现了一种独到的视角,和观点。

我一直对这位blogger相当的欣赏,现在竟然把他当作案例来分析,真是过意不去。在这里就把他的姓名隐去了。

Yesterday, phoned with my GF. She took a whole day to teach her niece Olympiad of Mathematics. I thought It is too cruel for a 12 year`s girl to give up her time of playing and to do something so boring (Maybe it is my misunderstanding, because I never feel interesting about Maths ). We had a small argument about how to educate. I felt a little bit of anger not for the argument but for myself. It is more than 20 years since I entered school. In primary school, middle school, university, I had practised thousands of exercises about Maths, Physics and so on, but I can not answer one question clearly, WHAT DOES SCIENCE MEAN? It means the ultimate rules? Or It means the method of how to find the rule under which our universe works? I was puzzled. It is a pity of me or our education that no one ever told me the basic concept of WHAT DOES SCIENCE MEAN.

keep thinking about this issue.

I think my brain does not balance very well, as it has strong understanding skills, but poor expressing skills. I get this feeling both for Chinese and for English. fortunetely at least I can read, think and write in Chinese well, while my Chinese writting skills are not so good. For english writting it is a real headache of mine. Sometimes when I am writting in english, I feel  my brain is short-circuited with no thought and direction. Although I read and listen to a lot of english material, I have not really  caught the sense of thinking in english. My first reaction for english words is to translate them into Chinese in my mind. I think it is the point.

I am seeking a way to improve my english writting skill in my everyday life. to write comments after the reading of english blogs. It should be a good way. Refining what I read and making some new thoughts could help me understand english material better and think in english better.


I make a collection of blogs  (The reviews comes from The Best of The Web By Forbes)

Gothamist,   Category: City Blogs
www.gothamist.com
This sophisticated, deliciously urbane city blog began in New York and rapidly spun off to a network of 11 other "-ist" sites, from Shanghai, London and Paris to Los Angeles, Philadelphia and Seattle. In each city, the format stays the same: news and lifestyle topics diced into food, sports, politics, theater, museums–umpteen categories customized to each city. (In Austin, one category was Tacos.) Bloggers in Shanghai recently weighed in on a recent Walmart opening, traffic jams and shelved plans for a Shanghai theme park.) In London, items included what to order in a tapas bar and news of the latest Mercury prize nominations for best Brit or Irish music. In New York, the granddaddy of the -ist sites, posts ranged from the closing of the kitschy landmark Howard Johnson in Times Square to an upcoming exhibit by artist Swoon (known for creating peep holes around the city.) A thoroughly enjoyable Ask Goth advice column addresses city urban dilemmas like finding a good tailor. Hyperactive message boards and plentiful links.

BEST: Extensive archives are searchable.
WORST: The Parisist site is only available in French.


BoingBoing , Category: Technology Blogs
www.boingboing.net
A collaboratively edited Weblog focusing on technology and society, BoingBoing is a massively popular repository of curious digital discoveries online. One post links to a new book, Free Software for Busy People written by a Bahraini doctor who is on a mission to help people understand why they should use free/open source software. Another link directs you to a novel how-to article (how about a lightsaber effect in your next home movie?). Did you know that President Bush’s former Health and Human Services Secretary, Tommy Thompson, onetime Governor of Wisconsin, is getting an RFID implant? BoingBoing posts aren’t strictly categorized, which says a lot: the site’s greatest strength is its spontaneous feel and "digital lifestyle" soft sell. Posts are frequent and many come with pictures. With archives dating back to pre-bubble tech giddiness of 2000, BoingBoing keeps readers digging for digital paydirt.

BEST: Great mix of culture, tech, humor and general geekery.
WORST: Many posts, loosely organized. Miss a day, miss a lot.


Sports Blogs
http://www.sportsblogs.org
Sports blogs-o-rama. This "people’s sports network" aggregates more than 1,300 individual blogs from all over the country, posting more than 30 new entries a day, most with links to top news items from the world of professional and college sports. While not searchable, you can browse by sport, date of the entry or team. (Sorry, pro teams only, and only in baseball, football, hoops and hockey.) Club with the most blogs? The Chicago Cubs, with 105. Stories cover every aspect of the sports world, from news that the NCAA is cracking down on college-sports gambling to an announcement about the new NFL Blitz video game (What’s this? Michael Vick will be replaced by a fictional player named "Ron Mexico"?).

BEST: The sheer volume of blogs in the network.
WORST: Some link rot. Ads can be overwhelming. Not optimized for Explorer on the Mac. 


Monster Blog, Category: Career Blogs
monster.typepad.com/monsterblog
For job hunters or just those seeking general career advice, this blog, written by members of Monster.com’s career advice team, offers a comprehensive array of general career and workplace issues in a personal, free-form style. Heavy on etiquette items, like topics such as IM-ing ethics (don’t get intimate fast, try to stick to pertinent information) and why you should or shouldn’t disclose an office romance. The blog also includes entertaining musings on issues such as why there isn’t a ‘Bring your Cat to Work Day’ and one writer’s list of "bottom of the barrel" jobs (including porto-potty cleaner, meter maid and slaughterhouse employee.) Linked news items and articles come from a number of sources ranging from the Wall Street Journal to CNN, as well as content from Monster.com and other career journals. Updated almost daily, the Monster blog has monthly archives dating back to October 2004, while a Recent Posts section gives you easy access to the latest.

BEST: Besides the well-known Monster brand name, Monster.com writers who actually love their jobs write the posts in a personal tone.
WORST: Can’t search archives by topic or category; few "comments" postings.


Joystiq, Category: Video Game Blogs
www.joystiq.com
This site, part of a network of top tier blogs from Weblogs Inc., has a vast collection of articles, news, sneak peaks and cheats on a slew of topics in the video game world. The stories and links are organized by "Atoms" from Arcade to Wireless to "Bits", from Action and Adventure to Sports. Click on First Person Shooters under Bits to find out about a recent cheat crippling update for Halo-2 online players or that the new Battlefield 2 has a lousy user interface. You can also check out upcoming driving games like TT Superbikes, about professional motorcycle racing or find out about a new online soccer game called Winning Eleven for PSP that is likely to give EASport’s FIFA franchise a run for its money. Each story is organized by genre as well as the type of system it works on from PC to Gameboy to Playstation2. Not sure who will play Hitman in the upcoming video game to movie creation? Joystiq tells us that it’s Vin Diesel. Have a particular question about a specific system or game? The site is easily searchable and has a complete selection to choose from.

BEST: Comprehensive. Plus Bits and Atoms hyperlinks are on every page to ease navigation.
WORST: The strategy section reads more like reviews than strategy


Romenesko, Category: Media Blogs
www.poynter.org/romenesko
After hosting two of his own media-oriented sites in the late 1990s, Jim Romenesko was snapped up by Florida’s nonprofit Poynter Institute, which promotes journalism education. Now he’s their highest paid nonexecutive employee. Why? Because he aggregates daily news and commentary on the world of media into a blog that is a must-click for most journos, covering everything from the pros and cons of "embedded" war journalists to the right to protect anonymous sources to the long-term impact of the New York Times Jayson Blair scandal. Word on the blogger street is that his dominance is fading, as more bloggers tackle the media world. FishbowlDC (http://www.mediabistro.com/fishbowldc) just started a regular feature highlighting the interesting media stories "missing from the world of Romenesko." But the fact is, Romenesko is scrutinized because it is so well known and influential.

BEST: Smart and comprehensive news about the news, from a veteran media watcher.
WORST: The feedback page doesn’t organize comments like most blogs, so you’ve got to wade through a poorly designed message board.


Gallery Hopper, Category: Art Blogs
www.galleryhopper.org
Photography central. This elegantly designed and highly readable site is brought to you by an avid photo lover who, while he claims not to be a connoisseur, displays a clear breadth of knowledge about photography and its market. It offers a fantastic resource: links to photo world news, events, books, market updates and reviews of museum and gallery exhibitions, from Rachel Papo’s images of Israeli women in the military to August Sandler’s German portraits that strayed from Hitler’s ideal (causing many to be destroyed by the Nazis). While entries range in length from little more than an off-handed comment to several paragraphs of commentary, blogmeister Todd Walker hits all the important shows and even calls attention to a recent podcast on the Metropolitan Museum’s Roger Fenton exhibition. But no matter how brief, comments are always thoughtful and historically informed. Be sure to scan the Collecting category archives for a treasure trove of tips and info about what to look for and notable sales, both past and future–it’s chock-full of meaty links. Nice photos accompanying many of the postings to whet your appetite.

BEST: Searchable by topic, date or keyword. We typed in Arbus and got eight items.
WORST: Looking for in-depth analysis? This isn’t the place.


Small Business Trends
www.smallbusinesses.blogspot.com
Founded in 2002 by Anita Campbell, former executive with Bell & Howell, this ambitious blog tracks a wide range of international trends and issues reshaping small businesses, through news commentary, blog reviews and links to expert articles, interviews and book summaries. You’ll have to sidestep the prosaic–inevitable articles on the explosion of home offices–for real insight, like the piece concerning the death of family businesses (which statistics reveal rarely make it past the third generation) or the posting on the "graying" of small business, as twenty-something entrepreneurs are supplanted by baby boomers. Updated even on weekends, the blog tries to be all things to all people, directly addressing businesses as diverse as second-hand clothiers, musicians and EBay resellers. But while it successfully pinpoints the trends, the too-brief articles rarely offer insight on to how to roll with them. One perk: Sign up for free magazine subscriptions to trade pubs like The Deal and Oracle magazine.

BEST: Pinpoints the latest trends in small business, from overseas franchising to specialty ice cream to senior care
WORST: Reviews of PowerBlogs are not categorized. You’ll have to click through each to find out what kind of blog it is. Example: A review for The Security Mentor, about efficient researching methods, is followed by a review of Ask Crabby, a seafood blog.


Rocketboom,Category: Video Blogs
www.rocketboom.com
One of the most well known vlogs, this site promises a three-minute video newscast every morning at 9 a.m. EST, Monday through Friday. The focus is rarely that of the top news stories of the day, as they claim a "heavy emphasis on international arts, technology and Weblog drama." Although it looks like a traditional gal-behind-a-desk newscast, the casual, irreverent tone comes in and you quickly realize this is no ordinary news show. Like a cyberworld Katie Couric, cheerful blonde host Amanda Congdon interviews documentary filmmakers and politicians, and then makes time for the latest funny video being passed around the Internet. A recent vlogcast featured a priceless performance by air guitar champion Rockeness Monster. The vlog is based in New York City but features vlogger correspondents from Boston, LA, and Minneapolis. Amanda is so likeable it doesn’t matter that sometimes what is happening on screen doesn’t make any sense.

BEST: Vlog host Congdon, plus the site’s sleek, simple design.
WORST: Hit or miss topics sometimes miss badly.


Marketing Vox
www.marketingvox.com
This Maryland-based site stakes out the online marketing world with deep news that’s rich in detail and background. It is an essential bookmark for those wanting to keep current on this fast changing arena. One recent posting discusses the booming e-commerce business in Europe (France alone had 40% growth last year) and the FTC’s demand for greater e-mail authentication. Another talks about how Ajax, the code used by Google Maps and Flickr to create lightning fast dynamic pages, could throw traditional page impression ad measurements into turmoil. Archives–stuffed with hundreds of stories–are broken down into more than 80 categories, such as Sector and Big Picture. There were 220 stories in the Advertainment section alone when we visited. You can also subscribe to a free e-mail newsletter mailed daily.

BEST: Each story lists related topics by category for further study.
WORST: Strictly a news site. Lacks how-to articles.


EconLog
econlog.econlib.org
Whether the topic is the economic effect of social security reform or the relationship between money and happiness, if it has to do with economics, it’s discussed here. Run by Arnold Kling and Bryan Caplan, who joined the site as Kling’s co-blogger in early 2005, EconLog successfully creates a forum for economic discussion that both students and scholars can appreciate. The co-bloggers post their ideas and recommendations, and often engage in lively debate with each other about subjects such as the effectiveness of health care or the usefulness of econometrics. A recent post entitled "Professors for Drugs" says that if consumers had more freedom to buy drugs without a doctor’s prescription as they can in countries like Myanmar, medical costs would plummet and health care might actually improve. While the site is hosted by the Library of Economics and Liberty, a free-market think tank, the bloggers’ posts and the users’ comments offer a diverse assortment of views.

BEST: The diversity of the economic topics discussed in the blog.
WORST: The length of the posts; while their content and style is enjoyable, some are a bit interminable.


Econbrowser
www.econbrowser.com
A well-produced blog covering a range of contemporary economic issues. Run by James Hamilton, a professor of economics at the University of California, San Diego, Econbrowser offers in-depth economic discussions in a conversational tone. While Hamilton talks about widely-discussed issues such as health care, interest rates and our foreign debt, he focuses many of his posts on his specific area of expertise: oil. He uses his knowledge gained through extensive research on the effects of oil shocks to provide readers with sophisticated analyses of oil markets and the commodity’s future. Hamilton also makes Econbrowser easy to read through his use of graphs and pictures, both of which he utilizes more than most other economic bloggers.

BEST: The conversational tone of the blog, which makes the lengthy posts easy to read.
WORST: Econbrowser is a new blog, so there’s only a limited archive section to further explore interesting topics. 


Blog of a Bookslut, Category: Literary Blogs
www.bookslut.com/blog
Bookslut Jessa Crispin is one of the most successful literary bloggers around, receiving thousands of hits daily to her interlinked Webzine and Weblog. Assisted by her cohort and friend Michael Schaub, Bookslut stays abreast of the national literary scene with quick, idiosyncratic entries that keep readers up-to-date on subjects like film adaptations of literature, the current government’s meddling with libraries and smarmy comments from smarmy writers. In response to author Lauren Baratz-Logsted’s complaint that her book has been under-reviewed, Crispin writes, "Chick lit is not reviewed in the New York Times for the same reason that Nora Ephron movies do not win Best Picture Oscars. It’s because they both suck." Reviews are often rant-like and rudely witty ("This new book focuses on the evils of lipstick, breast implants and skin care products. Way to focus your energy on issues that really matter to women") but still retain enough erudition to satisfy the informed reader. And the interviews are plentiful–up to four a month with such illustrious folks as poet Frank Bidart, author Dennis Cooper and academic luminary/essayist Camille Paglia.

BEST: Clear, uncluttered linkage between blog and zine.
WORST: Ads for books and journals that distractingly blink and increase page-loading time.


Technorati, Category: Meta Blogs
http://technorati.com
Read an article online lately that caught your eye? Want to know what people are saying about the new Harry Potter book? Punch the story URL or "Half Blood Prince" into Technorati and you’ll see which blogs are discussing them. Technorati tracks links in real time on some 13 million blogs, meaning that as soon as a blogger makes a post, Technorati knows what’s in it. That’s how the site is able to track what bloggers are talking about (accessible through the Popular section), and it’s how you can find which blogs are linking to your favorite article up to the minute. Google and Yahoo, by contrast tend to lag by a few days. Technorati also tracks photos on Flickr and Buzznet, as well as publicly shared browser bookmarks on Del.icio.us, making them accessible based on their "tags," or labels applied by other users. In addition, there’s plenty of customization you can do by signing up for a free account. And if you have your own blog, you can set up a profile with Technorati and display that from your blog.

BEST: Excellent blog search engine.
WORST: Browsing by tags can sometimes be glutted with sites in several languages.

2005年12月09日

大约上个月,在一次客齐集的聚会上遇到王建硕,因为没有深谈,只是对他灿烂的微笑有些印象。今天细细的读他的BLOG,渐渐的嚼出了些味道来。

一直以来都感觉自己很害怕写作,总是提不起笔来,即使脑子里有很多思绪萦绕,但要落于纸上仍然很难。直到这几天开始在自己的blog上涂鸦以后,才悟出一点道理来。blog是个私人空间,不必考虑读者的看法和评论,不必考虑自己要表现什么,要回避什么,只是平实的记录。所以在自己的blog上落笔很快,很随意。所见,所思,所感记录下来。所以说,写作是在突破一种心理障碍。突破的是不自信,羞于展现自己内心的障碍。

吐血推荐,麻省理工开放式课程计划 

http://www.cocw.net/mit/Global/all-courses.htm

内容很丰富,其中的中文部分是通过协作式翻译的方式进行的。

寻找生命小意义——我的价值观和理想

庞升东,一个在互连网打拼多年的草根创业者。29岁的年纪拥有千万身家,已经跨入到人生价值实现的阶段。很直白,坦率的陈述自己理想。

为什么写blog?为什么说写blog是企业战略,也是人生战略?

再摘一篇庞升东的冬冬,比较喜欢他直接,不矫情的风格。有啥说啥,不遮遮掩掩。

35岁前应该做好的十件事

老生常谈,但的却有道理。35岁离我还有6年时间,有好多事情需要去做。
