Trends in hardware Video Processing

I work on hardware video processing. The hardware video processing enables HD resolutions in real time and half the battery power compared to software solution.
Qualcomm with its Hardware engine has made real time HD video chat possible.

Qualcomm leads the industry in high performance mobile media hardware solutions and enables ooVoo's high resolution mobile video chat using Qualcomm's hardware codec capability. ooVoo allows up to six users to simultaneously participate on a mobile video call without compromising quality. The company's innovation in mobile video chat software, integrated with Qualcomm's differentiated hardware, will elevate the mobile experience to levels that have not been achieved by competitive video chat services.

Digital Still Camera market on decline?

The camera market is predicted to decline due to the quality of cell phone cameras growing dramatically better. DSC manufacturers need to pick a spot, find a growth opportunity, flesh it out and define it a new fault line.The next trends in digital still camera market are offering hybrid solutions in a single device, HD video recording, 3D video recording.

H.264 video comes to Firefox via Microsoft

Microsoft has released a new add-on for Firefox that will make the browser capable of playing back H.264 video by tapping into the codecs installed on the system. It uses the Windows Media Player plug-in to play back video. Obviously it will work only on Windows, only Windows 7 in fact.

The add-on looks for instances of HTML5 video, and replaces the video with an instance of the Windows Media player plug-in, pointed to the same video source file. Since the video in not actually playing in the browser itself, but in a plug-in, this has no advantages over just using the Flash Player.

But the Firefox owner, Mozilla, and Opera Software have instead decided to stand behind WebM and Theora as future standards for the web. In any case WebM is a better contender for the format of choice on the web in the future than H.264 due to its open nature.

Apple files for location update , video codec patents

Two notable Apple patent applications have been published by the USPTO. The first, Push-Based Location Update, centers on a proposed "Friend Locator" app that would let iPhone owners voluntarily share their location with friends and family. Updates would be sent over Apple's push notification service, and triggered automatically or through a manual command.

After logging into the app users would be presented with a friends list, showing names, addresses and distances. One optional view would sort people by "visibility," in other words whether or not they have location sharing toggled on. Tapping on a person's listing would show their place on a map, and offer the ability to get directions. To deal with privacy issues people could selectively hide information such as addresses and phone numbers; as need be, location info could be hidden from particular individuals.

The app is similar in concept to Google Latitude, or various other third-party programs available on the App Store. The key differences are Friend Locator's built-in status, and the various details of the app's interface.

The other patent is titled Arbitrary-Resolution, Extreme-Quality Video Codec. While extremely technical, it describes a codec with dynamic scaling and Golomb-based compression. Using a fractal dithering engine, video can be made to run on displays with low color depth. The filing is actually a continuation of a much earlier one, submitted in June 2004, offering the possibility that some implementation of the concept may already be in use.

Did you get the video you were looking for?. Try Visual search.

Multimedia is pervasive everywhere. To look for the image or video of interest from maze is challenging task.Text tag based search used presently in google and other search engines is not effective. Also tagging the millions of videos available on the internet is very difficult.Hence technology is taking  new directions to answer this challenge. See what it has to offer and current status of research in the following presentation.

Samsung Electronics Expands Into Medical Equipment

Samsung Electronics Co. bought a South Korean medical-equipment company, the first step in a long-discussed plan to diversify from consumer electronics.
Samsung's purchase Tuesday of a controlling stake in Medison Co., a maker of ultrasound monitors, was small enough that Samsung wasn't required to disclose the terms.
The purchase is more significant as a signal of Samsung's direction than for any financial impact. Medison's revenue amounted to 154 billion won ($134 million) in the first nine months of the year.
That is tiny in comparison to Samsung's four main product divisions—semiconductors, liquid-crystal-display panels, cellphones and television sets—with revenue of $22 billion to $38 billion each in the same nine months.
The decision to enter the medical-products field mirrors that by manufacturers in other countries—including General Electric Co. in the U.S. and Philips Electronics NV in the Netherlands—in decades past as the competitive landscape changed and earnings from consumer electronics faded. GE today is only a marginal player in electronics, while Philips gets only about one-fourth of its revenue and profit from electronics.
For more than a year, Samsung executives have touted plans to spend billions of dollars in the coming decade to enter higher-margin industries, such as medical products and solar equipment.
