Surveillance IP camera design with intelligent encoding for reduced bandwidth, higher quality Design How-To 12/21/2007 Post a comment Software configurable processors targeted at video applications are allowing closer coupling between the intelligence of the video system and the compression stages. The result will be a quantum leap in the quality and features of digital video surveillance systems. The ability to radically change encoder parameters based on the scene dynamics results in higher average compression ratios. This lowers bit rates and makes more efficient use of storage or transmission bandwidth.
NXP to buy GPS chip specialist GloNav News & Analysis 12/21/2007 Post a comment NXP Semiconductors (Eindhoven, the Netherlands) is paying at least $85 million in cash for GloNav Inc. the specialist developer of chips for GPS gear and other satellite navigation systems.
USB, Kleer plug into digital TVs News & Analysis 12/17/2007 Post a comment USB Implementers Forum is developing a variant of its technology to link mobile devices and TVs, and startup Kleer Corp. is announcing it has characterized its proprietary wireless link for standard definition video.
FireWire turns up heat with 3.2 Gbit/s spec Product News 12/14/2007 Post a comment Tomorrow's FireWire interconnects will quadruple in maximum data rates, hitting 3.2 Gbits/second thanks to the S3200 specification from the 1394 Trade Association which sees the new link, in part, as a low-cost alternative to HDMI for carrying uncompressed video.
Sensors group raises $37 million in Round B News & Analysis 12/11/2007 Post a comment Fabless semiconductor group SensorDynamics (Graz, Austria), which focuses on micro and wireless sensor products for automotive and industrial applications, has raised Euros 25 million ($ 37 million) in a Series B funding round.
Upgrades for PCI Express in the works News & Analysis 12/8/2007 Post a comment The PCI Special Interest Group is making progress on a basket of feature extensions to its latest 2.0 specification to enhance system performance as well as smooth a path for accelerators and storage devices, all of which should be available by June at the latest.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
