In general, a telemedicine workstation requires resources such as programmable audio, video, and imaging. The system also needs compression to sustain programs ranging from basic video teleconferencing to diagnostic quality audio, video, and medical images for interactive purposes.
The capacity to handle JPEG still image compression, MPEG high quality video and audio compression, H.320 videoconferencing via ISDN, and H.324 videoconferencing via telephone lines, is also a must.
To guarantee efficiency, the compression, acquisition, processing, and communication interface should all be tightly integrated. Lastly, the system requires support for acquiring information from electronic equipment such as stethoscopes, medical imaging equipment and high-resolution cameras.
Along with a well-equipped workstation, telemedicine also requires a communication network. To maximize its capabilities, the network should boast a favorable transmission medium. Most systems can provide ideal quality audio and video on an optic cable or satellite link with a bandwidth ranging between 28 Kbps to 155 Mbps and above. Keep in mind, the desired bandwidth will depend highly upon the clinical application in use and the desired level of interaction.
