Semiconductors May Grow 7.5% in 2013

by BillJewell in Semiwiki.com

The world semiconductor market in 2012 was $292 billion – down 2.7% from $300 billion in 2011, according to WSTS. The 2012 decline followed a slight gain of 0.4% in 2011. Fourth quarter 2012 was down 0.3% from third quarter. The first quarter of the 2013 will likely show a decline from 4Q 2012 based on typical seasonal patterns and the revenue guidance of key semiconductor companies.

The semiconductor market forecasts are shown as follows.

Samsung Silicon Valley innovation center and "Next Big Thing"

While Samsung has been one of the world's largest consumer electronics company, and has become the leading seller of smartphones, Young Sohn, Samsung's president and chief strategy officer, formally unveiled a new Silicon Valley innovation center (SSIC) and two funds worth $1.1 billion, which are intended to help find the "next big thing" in tech. Initially, the center will focus on big data, cloud infrastructure, mobile privacy, the Internet of Things, human interface, and mobile health, according to LA Times.

Young Sohn, Samsung's chief strategy officer, discusses plans for the company's new Silicon Valley innovation center.

In addition, the SSIC will be a place where entrepreneurs can build partnerships with Samsung's nine product divisions as they seek to develop their own ideas and turn them into products. The center will also be part the company's strategy to expand its mergers and acquisitions activity by identifying companies and technologies that can fill various product gaps.  The innovation centers seem in part meant to address the company's practical needs to tap more innovative ideas, but also to enhance its reputation as a place that innovates.

Later this year, Samsung will host a competition for artists, engineers, entrepreneurs, and other innovators to pitch their best ideas for how to improve lives with technology,  called as "$10-million SamsungCreate Challenge".

Young Sohn started at Samsung in August 2012. He has spent a long career leading several successful Silicon Valley semiconductor and storage companies after founding Intel’s PC chipset business, including Oak Technologies Inc which was acquired by Zoran Corp, then CSR PLC. Samsung bought CSR's wi-fi and bluetooth mobile chip tech last summer.

HEVC / H.265 Approved

High Efficiency Video Coding (HEVC) or H.265 is the current joint video coding standardization project of ITU-T Video Coding Experts Group (ITU-T Q.6/SG 16) and ISO/IEC Moving Picture Experts Group (ISO/IEC JTC 1/SC 29/WG 11). It was approved officially on January 25, 2013.

The design of HEVC, the next generation of video compression standards, incorporates the latest state-of-the-art technologies and algorithmic advances to address the persistent demand for broader usage of video content, video migration to broadband networks, diversification of mobile devices, ever-higher resolutions for cameras and displays, and increasingly high video quality.

HEVC is the latest in the series of video compression standards to be developed jointly by VCEG and MPEG. The HEVC project was formally launched in January 2010 following studies by both MPEG and VCEG to assess the readiness and availability of technology simultaneously with an analysis of industry needs for a new standard, and approval by the SC 29 and SG 16 higher-level committees to launch the JCT-VC. The major goal of the project is to develop the next generation video coding standard that could achieve the same level of video quality with a substantial savings (e.g. reduction by half) relative to the bit rate required by AVC. Initial measurements of the capability of HEVC, at this stage, indicate that its performance is already meeting or exceeding the targets set by this goal.

According to the ITU press release, "ITU-T H.265 / ISO/IEC 23008-2 HEVC will provide a flexible, reliable and robust solution, future-proofed to support the next decade of video. The new standard is designed to take account of advancing screen resolutions and is expected to be phased in as high-end products and services outgrow the limits of current network and display technology."

Companies including Cisco, ATEME, Broadcom, Cyberlink, Ericsson, Fraunhofer HHI, Mitsubishi, NHK, NTT DOCOMO and Qualcomm have already showcased implementations of HEVC. The new standard  includes a ‘Main’ profile that supports 8-bit 4:2:0 video, a ‘Main 10’ profile with 10-bit support, and a ‘Main Still Picture’ profile for still image coding that employs the same coding tools as a video ‘intra’ picture.
"The ITU/ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC) (formerly JVT) will continue work on a range of extensions to HEVC, including support for 12-bit video as well as 4:2:2 and 4:4:4 chroma formats. Another important element of this work will be the progression of HEVC towards scalable video coding. The three bodies will also work within the Joint Collaborative Team on 3D-Video (JCT-3V) on the extension of HEVC towards stereoscopic and 3D video coding."
