The AccessGrid currently supports image resolution of 352x288
pixels (H.261). Current research is focussed on expanding
the underlying video streaming services in the existing AccessGrid
infrastructure via the addition of new DV and MPEG2 codecs, enabling
the use of higher quality video formats, namely Digital Video (DV) (720x576
pixels) and High definition Video
(HDV) (1440x1080 pixels).
This requires the deployment of high-resolution video capture devices such as HDV/DV cameras capable of providing high quality images for AccessGrid collaborations. Delivering high quality video in the AccessGrid environment will increase the quality of the images streamed over the network. Any application that relies on high quality video images, for example tele-medicine or remote video monitoring, will benefit from this work.
