Broadcasters need to perform many remote interviews where the practicallity of an SNG link or availiblity of a OB hook up point would render it impossible.
Techex offers a solutions for remote interview based on JPEG2000 compression technology or very low latency H264. These cost-effective solution can provides high video quality, with no introduction of motion artifacts. JPEG2000 delivers very low latency, with a lag of approximately 100 ms for encoding, IP transport and decoding. H264 provides 80 ms end to end with much lower bandwidth requirement with very low artifact content.
Where IP connections permit high bit rates of approximately 100Mbps JPEG200 is ideal. Where lower bandwidth of from 5 to 20Mbps are available H264 can be employed. In addition, IP networks are easy to operate and IP competence is relatively easily available.
The links created could be permenant to facilities like trading houses or civil defence organisations or just for the duration of an interview using existing telco provided bandwidth.
IP circuits could be via fibre, copper, 3g Wireless or satellite.
