Using proven SuperENC technology from NTT Electronics, Hitachi High-Technologies can now offer an MPEG-2 encoder/decoder module solution that allows easy design of compact, high-quality, super-low-delay MPEG-2 systems.
These latest SDTV 4:2:0 and 4:2:2 modules have been optimised to offer 84ms (Pal), 70ms (NTSC) end-to-end delay for no extra cost.
The super-low delay is implemented through parameter setting on the SC2010E/SC2000D modules using finely tuned system timer clock and video buffer settings.
In super-low-delay mode, intraslice encoding is used with the I- and P-frame pictures.
This gives a stable 2.1 frame end-to-end delay (encode-decode) achieving 84ms pal and 70ms NTSC.
The modules demonstrate true MPEG-2 conformance to ISO/IEC13818-2 with transport stream (TS) output up to 60Mbit/s.
For added versatility, the SC2010E/SC2000D modules can be supplied with two stereo channels for audio.
Each module measures only 90 x 55mm, with low power consumption (under 5W per pair) and low latency make them ideal for a wide range of uses including remote broadcast, electronic news gathering, wireless camera and many security and surveillance applications.
The simple plug in and play modules for encoding and decoding can easily be configured to individual needs, meaning engineers can focus on defining and designing the requirements of their final encoding systems safe in the knowledge that the complex task of MPEG-2 encoding is already completed.
