HD video broadcast network launched by Akamai

In a move that has big implications for the developers of equipment that receives multimedia - whether tethered or portable - Akamai Technologies has launched the first platform to deliver HD video online to viewers using Adobe Flash technology, Microsoft Silverlight, and to the iPhone, at broadcast scale. The Akamai HD Network is the only solution that supports live and on-demand HD streaming with a highly-personalized and interactive online experience that matches and complements HD television.
As a first-of-its-kind streaming platform, the Akamai HD Network is designed as one, comprehensive HD network reaching multiple playback environments and devices, including Flash, Silverlight, and the iPhone. Using its globally-distributed EdgePlatform of more than 50,000 servers, the Akamai HD Network enables content providers to deliver more HD content than previously possible – due to its wide-scale distribution in 70 countries and increased throughputs in more than 900 networks.
This means that Silverlight and Flash will be a key element of any embedded multimedia software design.

The Akamai HD Network uses:
· Adaptive Bitrate Streaming - Unique network and player streaming process that is designed to enable uninterrupted playback at HD bitrates that seamlessly adjusts to fluctuations in available bandwidth to provide the best quality possible for each user
· Instant Response – Immediate response to viewer interactions with the video player, including sub-second time-shifting (such as pause, rewind, seek and play commands) video startup times, and seamless stream switching
· HD Video Player – Open, standards-based video player for faster time to market
· HD Player Authentication - Authenticates player for all three environments ensuring only authorized players access content

“Seeing is believing,” said Paul Sagan, President and CEO, Akamai. “With the Akamai HD Network, we are revolutionizing the way content traverses the Internet with a new approach to bringing an HDTV-like experience online. We’re entering a different online world, where many content owners and publishers need to deliver HD-quality video to a much wider online audience, with a higher level of interactivity for consumers. Delivering ‘web-quality’ content to ‘web-sized’ audiences is one thing, but delivering HD-quality content to broadcast-scale audiences is another.”
Two key trends have made it necessary to now evolve how streaming media is delivered on the Internet. First, online audiences have grown to broadcast scale. Second, those viewers are demanding higher quality content. Studies show that when higher quality video content is offered, viewer engagement time increases. Supporting this level of traffic requires a global network that can manage millions of simultaneous users streaming very high bitrate content. The Akamai HD Network was designed for large-scale broadcasters and film distributors looking to increase audience engagement and to expand revenues by complementing traditional mediums, such as TV and DVD, with the Internet.
The Akamai HD Network offers adaptive bitrate streaming capabilities across playback formats that are specifically optimized to work with Akamai’s HD EdgePlatform for the fastest and most consistent video bitrate switching - enabling an instant and uninterrupted viewing experience for consumers even at the highest bitrates. Leveraging Akamai’s entire HTTP footprint, video over Akamai’s HD Network is delivered from servers closer to audiences around the world. As a result, Akamai can more tightly control the amount of time the player needs to buffer before switching streams. The shorter the buffer, the faster the stream can adapt and respond to changing end-user conditions. The result is intended to create a seamless HD quality video experience – with little to no buffering.
“We are excited to see Akamai’s commitment to HTTP adaptive streaming as the future of online video delivery, as we have worked closely over the past year to build a robust end-to-end media delivery platform with IIS Smooth Streaming and Silverlight,” said Steve Sklepowich, director for Silverlight at Microsoft Corp. “Together, we’ve proven that these true HD experiences can dramatically increase online viewing times for broadcasters. In addition, Microsoft’s ability to deliver live and on-demand protected streams with Smooth Streaming and Silverlight, along with enhanced interactive experiences, such as multiple camera angles, alternate language tracks and in-stream data feeds, have raised the bar for online delivery using HTTP.”

SATA flash drives move to 62GBytes for embedded


Toshiba Electronics Europe (TEE) has moved to 32nm NAND flash technology for a series of solid state drive (SSD) modules, increasing the capacity and lowering the cost for embedded systems. The SG2 modules come in two types, one based on the new low-profile mini-SATA (mSATA) interface standard and the other a Half-Slim type, which uses a SATA connector. The drives are available in 30GB and 62GB modules. Volume production will start in October.
The two types of modules, each smaller than a business card, provide greater design flexibility and save space and cost compared to SSDs with hard disk drive form factors and cases. The 62GB module is only one seventh the volume and one eighth the weight of a 2.5-inch form factor SSD, and consumes half the power. With interface speeds up to 3Gbit/s, a maximum sequential read speed of 180MByte/s and a maximum sequential write speed of 70MByte/s,the modules will help bring the performance advantages of SSDs to notebooks, portable electronics and embedded systems. An advanced controller features a translation mode, which enables any drive configuration, and the drive supports 28-bit LBA (Logical Block Address) mode commands and 48-bit LBA mode commands. Multi-word DMA, Ultra-DMA modes and Advanced PIO commands are supported. The drives have an optional capability for secure Full Disk Encryption (FDE) backup that prevents unauthorized data access.
Embedded designers can either use the newer mobile mSATA interface where power is a key requirement, or existing, lower cost SATA.
The mSATA modules use the popular SATA interface in a small form factor module measuring 1.18 in. x 0.19 in. x 2 in. (30mm x 4.75mm x 50.95mm) that connects to the system board using a low profile SATA connector. Adaptive Power Mode and SATA Device Initiated Power Management typically reduce power consumption to less than half of the Read power level when the device is in idle, standby or sleep mode.
The Half-Slim SATA II modules feature a SATA connector, measure 1.18 in. x 0.19 in. x 2 in. (54mm x 4 mm x 39mm). The Half-Slim SATA II modules have the same SATA connector used on 2.5-inch HDD and SDD form factors. Thus, this smaller form factor can easily be used in applications designed to use 2.5-inch storage form factors. The Half Slim is also compliant to JEDEC SFF 8156.

First USB3 HD video camera


Point Grey, a Canadian developer of digital camera systems has developed the first industrial high definition video camera to use the USB3.0 standard.
It teamed up with Fresco Logic, a fabless semiconductor company that designs, develops and sells USB 3.0 chips for the launch at the 2009 Intel Developer Forum (IDF) in San Francisco. The live demonstration streamed uncompressed High Definition (HD) 1080p60 video from a Point Grey camera, equipped with a high performance Sony HD image sensor, to a USB 3.0 host controller from Fresco Logic on an ASUS P7P55D platform.
The prototype camera is designed and manufactured by Point Grey for the industrial market and uses the new 3 megapixel (MP) Sony IMX036 CMOS image sensor, which features high sensitivity, superior color fidelity, low power, and no smear. The sensor also supports an HD 1080p60 mode, which allows the camera to output raw, uncompressed 1920 x 1080 pixel images at 60 frames per second (FPS). Point Grey’s own software driver provides low-level control of the camera via the USB 3.0 bus. The camera is connected to a USB 3.0 interface card on the host side which is powered by the FL1000, a PCI Express to SuperSpeed USB Extensible Host Controller Interface (xHCI) host controller chip from Fresco Logic. The host PC uses an Intel i5-based P7P55D motherboard from ASUS.
"One of the potential benefits of the increased bandwidth of USB 3.0 is that it allows the main processor to handle compression. This means that different types of compression can be used for different applications and that some applications, like face recognition, can work on uncompressed video data for increased performance. We certainly see USB 3.0 as a key interface technology for machine and computer vision, and one we plan to integrate into future Point Grey imaging products," said said Vlad Tucakov, Director of Sales and Marketing at Point Grey.
