Webcast


 

A webcast is similar in intent to a broadcast television program but designed for internet transmission. Webcast clients allow a user to connect to a server, which is distributing (webcasting) the webcast, and displays the televisual content to the user.

Initially webcasts were non interactive, in other words, the user was not able to alter the content of the webcast or to interact with the subjects of the webcast. For the most part they were also hosted live (with recordings retained for later dissemination), however more recently there has been greater overlap between video conferencing and webcasting such that webcasts have been generally consigned to being recordings of video conferences and training material where there is much less demand for an interactive session.

A notable webcast took place in September 1999 to launch NetAid, a project to promote internet use in the world's poorest countries. Three high profile concerts were to be broadcast simultaneously on the BBC, MTV and over the internet; a London concert at Wembley Stadium featuring the likes of Robbie Williams, George Michael; a New York concert featuring Bono of U2 and Wyclef Jean; a Geneva concert. The site had been designed to handle ten times the number of viewers of any previous webcast.

More recently, Live8 (AOL) claimed around 170,000 concurrent viewers (up to 400Kbps) and the BBC received about the same (10Gbps) on the day of the 7 July 2005 bombings in London. The growth of webcast traffic has roughly doubled, year on year, since 1995 and it directly linked to broadband penetration.

On July 26-29, 2004, the Democratic National Convention in Boston used a more advanced webcasting technology called Avacaster to give thousands of potential voters the chance to interact with and ask questions of politicians, convention delegates, and media personalities.

CMU Celebrates 25 Years of Field Robotics

The CMU Robotics Institute recently held a celebration and symposium, called FR25, commemorating the 25th anniversary of the CMU Field Robotics and the 60th birthday of Red Whittaker, who founded the discipline of field robotics. A wide range of robot experts spoke at FR25 including Robin Murphy, Marc Raibert, and, of course Red himself. The CMU folks did a webcast of the event and the video of most of the talks is still available for those who'd like to view them. Take it a look; it's some interesting stuff.

Gallery: Fleet-Footed Flyby Reveals Mercury?s Unseen Surface

: Photo: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of WashingtonWASHINGTON, D.C. -- The first mission sent to orbit Mercury flew by the planet closest to the sun for the second time earlier this month, capturing images of most of its previously unseen surface. On Oct. 6, NASA's MErcury Surface, Space ENvironment, GEochemistry and Ranging spacecraft, or Messenger, passed just 125 miles above Mercury and took more than 1,200 pictures of its heavily cratered surface. During the second of three scheduled flybys, the probe used Mercury's gravity to alter its path, which will help it eventually settle into orbit around the planet in 2011. A briefing about the early scientific findings from the mission will be shown live in a NASA Television webcast Oct. 29 at 1 p.m. EDT. Left: During its approach to the solar system's innermost planet, NASA's Messenger probe took this image of a crescent Mercury. The spacecraft was still an hour and a half from its closest encounter when it imaged this terrain, which hadn't been seen on Messenger's first flyby or by the Mariner 10 spacecraft, which flew by Mercury in 1974 and 1975. The image is one of a set of 11 taken through different filters to study the colors of the surface.: Photo: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of WashingtonThis image, taken as Messenger flew away from its closest approach to Mercury, was one of the first to be sent back to Earth. The bright spot near the center of the image is Kuiper crater. Most of the terrain to the east of Kuiper had never been seen before. A striking characteristic of this newly imaged area is the large pattern of rays that extend from a relatively young crater in the northern region of Mercury to south of Kuiper. : Photo: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of WashingtonJust an hour before Messenger reached its closest approach to Mercury, the probe took this close-up picture of a heavily cratered terrain in an area that had never before been imaged. The features in the foreground, near the right side of the image, are close to the line between the sunlit day side and dark night side of the planet, so shadows are long and prominent and make the topography stand out.: Photo: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of WashingtonThe sun's slanting rays illuminate Machaut crater in this image. The crater, named for the medieval French poet and composer Guillaume de Machaut, is about 60 miles across. The floor of the crater has been coated with lava, which has in turn been peppered with more small craters. : Photo: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of WashingtonThis shot was taken just minutes after Messenger passed its closest point to the surface of Mercury, while the spacecraft was moving at 3.8 miles per second. It is the highest resolution color image ever taken of the planet. The largest crater, near the top of the photo, is called Polygnotus and is 83 miles in diameter.

Wash. Post uncritically reported McCain's attack on Obama for "wanting to raise taxes" on Americans like Joe the Plumber

In an October 17 Washington Post article, staff writers Dan Balz and Shailagh Murray reported that at a campaign rally in Philadelphia, Sen. John McCain "railed against [Sen. Barack] Obama for wanting to raise taxes." Balz and Murray also uncritically quoted McCain saying of the October 15 presidential debate: "The real winner last night was Joe the Plumber [Sam Joe Wurzelbacher]. Joe's the man. He won, and small businesses won across America. ... The American people are not going to let Senator Obama raise their taxes." But Balz and Murray did not point out that Obama has proposed cutting taxes for low- and middle-income families and raising taxes only on households earning more that $250,000 per year. Nor did they note that, according to what he recently told ABC News' Diane Sawyer, Wurzelbacher does not make $250,000 or more and therefore would not be subject to a tax increase under Obama's tax proposal. Balz and Murray also did not mention that Wurzelbacher also reportedly said he would not make more than $250,000 if he bought the business he has expressed interest in purchasing. On the October 16 edition of ABC's Good Morning America, Sawyer asked Wurzelbacher: "[Y]ou're not taking home $250,000 now, am I right?" Wurzelbacher replied: "No. No, not even close." Sawyer then asked: "And you were you asking about the prospect, the hope, that someday you would make $250,000, and you were saying you didn't want that to be taxed?" Wurzelbacher responded: "Well, exactly. Exactly." Additionally, in an October 16 post on his blog, ABC News senior national correspondent Jake Tapper wrote that according to ABC News' Chris Bury, Wurzelbacher "acknowledged that he wants to purchase the plumbing business for $250-280,000, not that he would net that much in profits. He would make much less, he said." Further, during an October 15 webcast, CBS Evening News host Katie Couric asked Wurzelbacher: "Well, [Obama] supposedly will raise taxes only on people who make over $250,000 a year. Would you be in that category?" Wurzelbacher responded: "Not right now at presently, but, you know, question -- so he's going to do that now for people who make $250,000 a year. When's he going to decide that $100,000 is too much? I mean, you know, you're on a slippery slope here. You vote on somebody who decides that $250,000 and you're rich? And $100,000 and you're rich? I mean, where does it end? You know, that's -- people got to ask that question." Moreover, an October 16 MSNBC.com article reported that if Wurzelbacher buys the company for which he currently works, as he has said he hopes to do, "Obama's tax plan wouldn't affect him" because "Ohio business records show the company's estimated total annual revenue as only $100,000. Actual taxable income would be even less than that." From the article: Wurzelbacher also acknowledged that he had no specific plans for buying Newell's business, saying he and Newell had simply talked about the idea from time to time. He might have difficulty making the purchase: Court records from his divorce show that Wurzelbacher made $40,000 in 2006. Even if he did buy Newell Plumbing and Heating, Obama's tax plan wouldn't affect him. While Wurzelbacher told Obama that he would be taxed at a higher rate because the company grossed more than $250,000 a year, Ohio business records show the company's estimated total annual revenue as only $100,000. Actual taxable income would be even less than that. In any event, Obama's tax plan specifies that the higher rate would apply only to income above the $250,000 threshold. Assuming Wurzelbacher's income as owner somehow hit $280,000 -- the top end of his supposition of the company's revenue -- only the extra $30,000 would be taxed at a higher rate. From Balz and Murray's October 17 article: McCain took his debate performance to the Philadelphia suburbs, where he talked about "Joe," the Ohio plumber who became the focal point of Thursday's debate. McCain railed against Obama for wanting to raise taxes, a mistake that he said would plunge the country from recession to depression. "I thought I did pretty well," McCain said. "The real winner last night was Joe the Plumber. Joe's the man. He won, and small businesses won across America. ... The American people are not going to let Senator Obama raise their taxes." [McCain senior adviser Steve] Schmidt said that Obama's comments to the Ohio plumber last week, in which the senator from Illinois said he wants to spread the wealth to more Americans, were "anathema" to the American people and set up a sharp contrast for the last weeks of campaigning. "Obama has every potential to tax and spend the country into a depression, and we will focus acutely on that," Schmidt said.

MSNBC's Hall said "it would be rude to ask Joe [the Plumber] what his income is" -- but it's key issue

On the October 16 edition of MSNBC Live, during a discussion of Sam Joe Wurzelbacher ("Joe the Plumber") -- mentioned by Sen. John McCain numerous times during the October 15 presidential debate as an example of a person whose taxes would increase under Sen. Barack Obama's tax plan -- host Tamron Hall said that "according to the federal government's Bureau of Labor Statistics, the national average for a plumber: $45,000. ... I think it would be rude to ask Joe what his income is." But Wurzelbacher's income -- or expected income -- is the issue in determining the veracity of McCain's charge. Wurzelbacher told ABC's Good Morning America host Diane Sawyer that he does not make $250,000 or more -- and reportedly told ABC News' Chris Bury that if he purchases the plumbing business he intends to purchase, he would still make less than that -- which means that his income would not be subject to a tax increase under Obama's tax proposal. Obama has proposed cutting taxes for low- and middle-income families and raising taxes only on households earning more than $250,000 per year. In an October 16 post on his blog, ABC News senior national correspondent Jake Tapper wrote that according to ABC News' Chris Bury, Wurzelbacher "acknowledged that he wants to purchase the plumbing business for $250-280,000, not that he would net that much in profits. He would make much less, he said." Tapper also noted that "Wurzelbacher this morning told ABC News' Diane Sawyer that he was talking about, in Diane's words, the prospect, the hope that someday he would make $250,000." Indeed, during the October 16 edition of Good Morning America, Sawyer asked Wurzelbacher: "[Y]ou're not taking home $250,000 now, am I right?" Wurzelbacher replied: "No. No, not even close." Sawyer then asked: "And you were you asking about the prospect, the hope, that someday you would make $250,000, and you were saying you didn't want that to be taxed?" Wurzelbacher responded: "Well, exactly. Exactly." Additionally, during an October 15 webcast, Couric asked Wurzelbacher: "Well, [Obama] supposedly will raise taxes only on people who make over $250,000 a year. Would you be in that category?" Wurzelbacher responded: "Not right now at presently, but, you know, question -- so he's going to do that now for people who make $250,000 a year. When's he going to decide that $100,000 is too much? I mean, you know, you're on a slippery slope here. You vote on somebody who decides that $250,000 and you're rich? And $100,000 and you're rich? I mean, where does it end? You know, that's -- people got to ask that question." From the 11 a.m. ET hour of the October 16 edition of MSNBC Live: RYAN FOWLER (WNWO reporter): So, Joe has some strong opinions on this year's election. He says he's a conservative, but like you mentioned, he doesn't want to -- kind of give away who he's going to vote for. But after last night, he said McCain won that final debate, so you have to think he might be leaning towards McCain -- Tamron. HALL: Yeah, you would think that, and we actually got a little bit of data from our friends over at CNBC -- people wanting to know what the average plumber makes. And according to the federal government's Bureau of Labor Statistics, the national average for a plumber: $45,000. Their actual average hourly rate is $22.76. I think it would be rude to ask Joe what his income is. But it's interesting, Ryan, that he has been kind of secretive about who he's voting for, in that, he's been so vocal this morning. From the October 16 edition of ABC's Good Morning America: SAWYER: Well, I just want to ask you now about the issue that was raised, because it's been a little confusing to me as I tied -- tried to sort it out here. To get straight here, you're not taking home $250,000 now, am I right? WURZELBACHER: No. No, not even close. SAWYER: And you were asking -- WURZELBACHER: No, it's -- SAWYER: -- about the prospect, the hope, that someday you would make $250,000, and you were saying you didn't want that to be taxed? WURZELBACHER: Well, exactly. Exactly.
