CubeX 3D Printer
3D printing, "The third industrial revolution", is coming to real.
3D Systems' CubeX™ 3D printer, the ultimate desktop 3D printer that can print as big as a basketball in triple color,
was awarded the CNET Best of CES Award for Hottest Emerging Tech at the 2013 International CES. It offers 3 color print at a desktop, prints up to 1.5 times faster than the old model, and offers more materials, including both ABS and recyclable PLA plastics. It also allows for printing over a direct USB connection.
In cubify.com website, it shows services to support one, dual color, and 3 color printer, depending on cartridges. According to CNET, "3D Systems says it costs more than buying a multicolor printer outright, but if you decide you'd like to add a print head to either your single- or dual-color CubeX, the company will send you the necessary parts. The single-color model still has the same build area and finer printing resolution as the others, though, making it a competitive deal next to the single-color Replicator 2 given the CubeX's larger build volume."

Video/Audio Stream Demuxing/Muxing Using ffmpeg
ffmpeg is a very fast video and audio converter that can also grab from a live audio/video source. It can also convert between arbitrary sample rates and resize video on the fly with a high quality poly phase filter.
ffmpeg reads from an arbitrary number of input "files" (which can be regular files, pipes, network streams, grabbing devices, etc.), specified by the -i option, i.e., and writes to an arbitrary number of output "files", which are specified by a plain output file name. Anything found on the command line which cannot be interpreted as an option is considered to be an output file name.
FFmpeg Windows Builds are available at Zeranoe FFmpeg Builds.
The syntax is
ffmpeg [[infile options][`-i' infile]]... {[outfile options] outfile}...
Therefore ffmpeg can be used for video/audio stream demuxing (splitting) and muxing (recombining).
For example, get the video only and audio only from a file:
If we want to recombine the audio and video files to one file
ffmpeg -i test.264 -i test.pcm -vcodec copy -acodec copy -f avi test.avi
The following video and audio codecs are supported with ffmpeg:

- Video: ffmpeg -i test.avi -vcodec copy -f h264 test.264
- Audio: ffmpeg -i test.avi -acodec copy -f s16le test.pcm, assuming pcm_s16le is applied when audio stream is captured. pcm_s16le is a common file format when TI DSP is used
Or one command line does it all:
ffmpeg -i test.avi -acodec copy -f s16le test.pcm -vcodec copy -f h264 test.264
If we want to recombine the audio and video files to one file
ffmpeg -i test.264 -i test.pcm -vcodec copy -acodec copy -f avi test.avi

Qualcomm Snapdragon 800 Processors
Qualcomm announced their latest mobile chip - Snapdragon 800 Processors at CES 2013.
- Quad Core Krait 400 CPU—speeds up to 2.3 GHz, per core
- Adreno 330 GPU—featuring patented Flex Render Technology and leading edge API’s that are designed to expand the use of GPU processing for general computing and other SoC tasks, the Adreno 330 GPU offers a 2 times better compute performance than Adreno 320
- 2x32bit LPDDR3 RAM at 800MHz – with industry-leading memory bandwidth of 12.8GBps.
- 4G LTE Cat 4 and 802.11ac—these connectivity options offer blazing fast, seamless connectivity with cellular modem boasting data rates up to 150 Mbps and 802.11ac at speeds up to 1 Gbps.
- UltraHD—video can be captured, played back and displayed in UltraHD (previously called “4K.”) The resolution has four times as many pixels as 1080p. (1920x 1080 versus 4096 × 2304)
- HD Audio—support for DTS-HD, Dolby Digital Plus and 7.1 surround sound.
- Dual Image Signal Processors (ISPs) up to 55MP – with support for up to four cameras and allows for 3D captures, photo merging into a master 55MPixel image, separate autofocus and captures, 1080p30 video captures.
- Overall Performance Boost—the Snapdragon 800 processor is expected to deliver up to 75% better performance than the Snapdragon S4 Pro.
Although Tegra 4 will be delivering 3.5x the performance of the Tegra 3 while consuming 45% less power, Snapdragon 800 will give a head to head competition against Tegra 4.

High Quality Digital Camera Processor - COACH16
COACH16™ is CSR’s flagship Digital Camera Processor that provides support for the most advanced features in today’s high-performance still and motion-image portable devices.
Still Image Capture Features
- Supports Digital Single-Lens Reflex (DSLR) cameras, Mirrorless Interchangeable Lens Cameras (MILC), and high-end Digital Still Cameras (DSC);
- Smart Flash: When flash is used, photographers are often frustrated with the results, which can include a washed-out subject in the foreground and an underexposed background. Smart Flash takes TWO pictures in very rapid succession – one with flash, one without – and uses a hardware-based algorithm to combine them. Since Smart Flash is hardware-accelerated, the processing and combining of the images, including precise picture alignment and motion compensation, occur with minimal lag;
- High Dynamic Range Photography (HDR);
- State-of-the-art Image Processing Pipeline & Algorithms;
- Multi-Frame Noise Reduction for still images
- Ultra fast sustained and burst capture rate. Extremely fast click-to-click performance – enabling true endless sustained burst photography with no lag while the user is forced to wait for the processor to “catch up”. Even with very high-resolution camera, it can maintain an endless “burst” at a high frame rate.
- 3D
Video Capture Features
- Full HD (1080p) 60fps High Profile H.264 video compression;
- Super Resolution; Processing the full size images from the sensor and downscaling them to video resolution using a highly quality scaler;
- Real-time video streaming;
- Motion Compensated Temporal Filtering (Video MCTF 3.0)
- 3D

Tegra 4 SOC, First Quad-core Cortex-A15 Chip
Nvidia unveiled its Tegra 4 processor Sunday at CES.
Chips
The Tegra 4 is based on ARM's quad-core Cortex-A15 processor and also packs in 72 graphics processing unit (GeForce GPU) cores, six times the GPU horsepower of Tegra 3. The four Cortex A15s will run at up to 1.9GHz. LP-DDR3 dual-channel memory interface is supported. 4G LTE modem is optionally built in.
Photography
High-Dynamic Range (HDR) capture is essential for high quality photography. HDR combines a series of photographs taken at different exposure settings to provide a wider dynamic range and is processor intensive. The iPhone 5 takes about 2 seconds to capture an HDR image, said Nvidia CEO Huang, while the Tegra 4 can snap two shots almost simultaneously and combine them.
Video and Battery Life
The Tegra 4 will also enable 4K ultra high-definition video support. Tegra 4 includes a second-generation battery saver core for low power during standard use, and PRISM 2 Display technology to reduce backlight power while delivering superior visuals.
Tegra 4 consumes up to 45 percent less power than its predecessor, Tegra 3, in common use cases. And it enables up to 14 hours of HD video playback on phones.
