High Definition Visual Communications
Organizations understanding the need to adapt to the modern pace of business have already realized the communications efficiencies that can be achieved by combining traditional audio and video technologies with IP protocol capabilities. Now, the addition of HD resolution video and audio expands the window of opportunity for professionals even further.
These concepts are at the center of Sony’s new IPELA HD visual communications system. The system combines the PCS-HG90 codec with the optional PCSA-CHG90 pan-tilt-zoom camera, resulting in the two-way, real-time transfer of HD-resolution video and stereo audio over an IP network.
In developing this system, Sony has applied its unique understanding of HD technology, refined over time through the successful introduction of the BRAVIA and Grand WEGA HD consumer televisions for consumers and its lines of professional HD broadcast and production equipment.
The application of this HD pedigree to the broader business-to-business world means that in professional offices connected by the IPELA HD solution, product issues and the development of marketing campaigns can all be addressed in real time, re-defining the decision making and business planning processes.
HD visual communications enables new levels of resolution and clarity that just aren’t possible in standard definition. Further, this technology can help organizations adapt to the new way of business, where faster-decision making, faster collaboration and faster approvals means faster time to market.
For example, using IPELA HD visual communications, an apparel company with offices in Paris, New York and Montreal can use the system’s multi point capabilities to bring together a design team to discuss and compare the new fall line -- evaluating colors, packaging and displays. This can all be done in real time, without having to wait hours or days for approvals, or having to send materials back and forth for review.
These capabilities also apply to industries such as automotive design, engineering and architecture; any field where color, detail, and texture need to be closely scrutinized before final production begins, however, the key decision-makers are geographically dispersed among satellite offices.
Finally, in broadcast, the system is perfect for conducting live, on-air interviews between an anchor desk and remote locations or for fixed camera applications like weather or traffic reports. News organizations can quickly produce and air extremely high-quality content, and can easily insert live HD material into programs. Production crews working on TV shows or motion pictures can also benefit from HD video transfer, sharing “digital dailies” of the day’s shooting for faster approvals or even simultaneously reviewing footage in real time among multiple production sites to be viewed by editors, producers and directors.
The PCS-HG90 codec supports the H.264 HD video protocol with compression of 1280 x 720 at 30P or 60P, and a network video transfer bandwidth of up to eight Mbps. An HD-SDI interface enables full digital transmission from capture through final display, and it also allows the codec to be used with compatible cameras from other manufacturers, offering users a greater level of flexibility.
An equally important but often overlooked element necessary to produce a dynamic visual communications experience is high-quality audio. The IPELA HD system incorporates the highest level of audio capabilities, delivering MPEG-4 AAC stereo audio with stereo echo canceling capabilities. An internal multipoint control unit (MCU) supports communications connectivity among four sites with site name display and full-screen views possible in broadcast and voice activation modes.
