If you have multiple HDMI sources connected to a pre-pro, switcher or TV display, have you ever noticed the rather irritating lag time during switching? I do, I have a desktopdisplay that take about 10 seconds then display a failed HDCP authentication message (it works nevertheless) on the screen every time I turn the TV on. On my Home Theater setup, I have five HDMI sources connected to a Preamp processor. The lag time varies from 3 to 5 seconds, better than the LCD display but could definitely improve with the InstaPort from Silicon Image.
With Silicon Image’s InstaPort technology, HDMI access time can be further accelerated and shaved the lag time down to less than a second! The company explains the InstaPort authenticate HDCP process instantaneously and simultaneously when the devices are connected, not when the input is selected.
The company also says InstaPort be featured in Samsung’s next generation TVdisplays and is currently under evaluation at nine of the top ten HDTV manufacturers for next year’s models.

Today’s IP choices for the Universal Serial Bus (USB) cover many different types of interfaces for a wide variety of applications�including portable consumer products. Power consumption and small form factors are key issues. SoC designers must also consider new requirements imposed by smaller technology nodes, especially for the USB PHY. As the most successful connectivity standard in history, USB has expanded from connecting PCs and PC peripherals to flash storage, digital imaging, audio and video, wireless, automotive, and now to tremendous growth in mobile phones. A force behind this growth are the ongoing enhancements to the USB standard, including the PictBridge specification that supports direct connections between printers and digital cameras and most recently, the High Speed Inter-Chip (HSIC) and Link Power Management (LPM) standards that lower power, area and enable chip-to-chip connectivity with USB. We will also begin to see the emergence of the USB 3.0 standard, which can deliver over 10 times the speed of today’s USB 2.0 connection.
Using PCI-Express platform circuitry, LeCroy’s Voyager protocol analyzer exerciser system tests devices, systems and software under the USB 3.0 (SuperSpeed USB) standard. The device provides simultaneous protocol capture of both USB 2.0 and USB 3.0 signaling, and uses the de facto standard CATC Trace display to illustrate USB 3.0 protocol. The analyzer will target fast sync-and-go transfer applications in the PC, consumer and mobile segments that are necessary as digital media become ubiquitous. Advanced triggering, hardware filtering, and Spec View are included.

Soon the world will move 10 times faster. The movement of the data among digital devices will accelerate incredibly. Soon the world will witness and experience the super power of the all new Universal Serial Bus version named USB 3.0. This specification is still in its prototype stage, but it will hit the consumer market soon. The specifications of the USB 3.0 have already been decided and developed. USB 3.0 is aiming at a bandwidth which is 10 times faster than the current USB, i.e. USB 2.0. This new version has lots of awesome improvements. It will allow users to transmit data at a rate of 5Gbps. That means a PC user will now be able to transfer a whole DVD quality full length movie within seconds. Wouldn’t that be nice? It will totally change the way the world communicates, or in other words, the way various peripheral devices talk to each other. Apart from the speed, one other major improvement in this new version is that it simultaneously supports two way communications (full duplex transfers). This means that the devices connected via USB 3.0 will be able to send, as well as receive, signals at the same time. This is in contrast to the USB 2.0 devices, like the Super Talent Pico, which can only transmit one signal at a time. It is believed that the new USB standard will also lead to better CPU usage and will be backward compatible with USB 2.0/USB 1.0 too.USB 3.0: Get ready to welcome the future
