What's New: Video Technology
Feb 1, 2005 12:00 PM
The AJ-SDC905 dual-mode camcorder features three 2/3in. CCDs, 12-bit DSP for 65dB signal-to-noise ratio, a sensitivity of f/13 at 2000 lux, and an IEEE 1394 I/O for 50Mbps nonlinear editing. The camcorder offers 4:2:2-sampled DVCPRO50 or 4:1:1-sampled DVCPRO recording, at 16:9 or 4:3 aspect ratios. A 6 second pre-recording function is standard. The Retake mode enables users to automatically back up to the start of the last take and record over it.
Video Distribution System
The MediaEdge-LEB standalone video encoding appliance uses MPEG compression to deliver professional-level video over LANs in auditoriums, lecture rooms, or sports stadiums. It can instantly rebroadcast the encoded stream to a MediaEdge-STB2 set-top box or a MediaEdge-SWT2 software client for playback. A built-in server provides client access to the encoded video stream. The MediaEdge-LEB supports NTSC and PAL video and provides unicast and multicast distribution capabilities.
Digital Media Processor
ANT; Texas Instruments
The DM642 DSP-based digital media processor now uses ANT Galio software for such applications as Internet protocol TV (IPTV) decoders, set-top boxes, and videophones. ANT's browser-based content presentation and control solution complements the digital media capabilities of the DM642 platform. The integrated solution allows manufacturers to use content formats including H.264, MPEG-4, MPEG-2, and Microsoft Windows WMV9.
Omneon Video Networks
MigrateTool software streamlines the conversion of ingested material into QuickTime for use in the Omneon Spectrum media server system. This simplifies the server's integration into production and playout workflows by enabling users to translate and work with existing material easily. The software preserves the metadata and vertical interval data stored in each individual clip for easy conversion.
The ORCA Capture Station HD MPEG-2 record and playback solution encodes SDI or HD-SDI to HD MPEG-2 at rates of up to 160Mbps directly to the system's hard drive. This process can be previewed live or played back at a later time via composite, DVI, SDI, or HD-SDI video outputs. Users can control the encoding process through selection of parameters such as GOP structure, 4:2:0 and 4:2:2 encoding profiles, and compression bit rate.
Key Digital Systems
The HD Explorer HDMI video card features an integrated digital video scaler to accommodate virtually any component video, RGB, composite video, or S-Video source on Pioneer's 43in. and 50in. CMX open-slot plasma displays. The unit offers four all-digital HDMI inputs, with output directly interfaced to the plasma through a proprietary internal digital RGB connection.
FireWire Range Extender
The TP-300FW converts DV FireWire signals for transmission over unshielded Cat-5 cable up to 300ft. A second TP-300FW converts the signals back to their native format. The range extender eliminates the need for expensive repeaters to overcome the inherent 14.75ft. distance limitation on IEEE 1394 FireWire signals. Additional units can be added to extend the overall signal range to 600ft.
Niagara SchedulStream enables the remote management and scheduling of streaming and encoding servers. Applications include coordination of multiple encoders for training sessions, remote scheduling of classroom or conference room encoding, and simultaneous encoding of Windows Media and RealNetworks formats for distance learning applications. Streaming templates can be used to optimize scheduling. The system also simplifies digital video archiving, allowing users to store content locally or on a network.
The iCon H600 6000 ANSI lumen LCD projector displays HDTV video at 1920×1080 resolution on a 16:9 canvas for increased flexibility in presentation settings. Picture-in-picture allows simultaneous display of up to four video and data sources, and the presenter can save and recall any window layout. Multiple window frames can be positioned and scaled with a mouse and keyboard, rather than via the traditional remote control. Projector control can be passed instantly over LAN to any meeting location.
The X75HD combines up/down/crossconversion of up to seven input video formats to almost any output format with HD frame synch and extensive video and audio processing capabilities in 1RU, for use in analog, digital, or HD hybrid facilities. Video processing features include level/color control, optional 3D adaptive color decoding with time base correction, optional noise reduction, and up- and downconversion with aspect ratio conversion. The unit provides 16 channels of internal audio processing that include timing with video for lip synch corrections.
Front Projection Display
The 1024×768 PJ755D display delivers 2700 lumens and features an integrated DVI input with high-definition content protection for widescreen applications. Additional connectivity options — including composite video, component video, and S-Video — let users select the best display mode for entertainment or PC applications. Other features include picture-in-picture, auto-image adjustments, and digital keystone correction.
The 17in. DT-V1700CG and the 19in. DT-V1910CG rack-mountable color video monitors feature 800 and 900 TV lines of hori-zontal resolution, respectively, for applications including postpro-duction, quality control, and general monitoring. Users can select 4:3 or 16:9 aspect ratios. The monitors feature an increased range of interface cards; a discrete 16:9 removable bezel; and a dual HD-SDI card for simultaneous, two-input, auto-selection of SD and HD-SDI signals. Three blank connection panels can be populated with audio and video I/O modules according to user needs.
The lightweight LX25a projector features 1024×768 resolution, 2500 ANSI lumens, 450:1 contrast, and a short-throw zoom lens. An auto setup feature simplifies startup. PIN code and password protection options prevent unauthorized operation. The unit can project images onto green surfaces, such as chalkboards, for use in classrooms and other settings where a screen is not available.
