second 3G-SDI connector. Multiple indiePOVs can be daisy-chained and simultaneously configured via one remote connection. “The IndiePOV is one of the finest miniature cameras ever brought to market and is ideal for use across our entire range of portable support systems,” comments Hewitt. “It can be used in single-camera, 3D and multi-camera modes. The build quality is also superb and the value for money nothing short of breath taking.” [Pic 2-3 cols: IndiePOV.jpg Cap: Indiecam twin IndiePOV cameras offer 3D HD Two IndiePOV cameras can be linked together with control system IndieTwin which features an IndieShuttle for recording and camera control. “Once the control of 3D-rigs is implemented, we will offer a remote control with separate interfaces for interocular and convergence,” says Hewitt.

meet the market’s ever changing needs,” reports Bradley who has two products in prototype. “For example, our small HDC100 is to have full motion control available shortly. We also are unique in the way that our range matches and mates products to simplify connectivity and integration. We are not just a one or two product company and although we recognise that other companies who are do this very well it does leave the customer having to source equipment from several suppliers with the associated integration problems. Our aim is to offer options that integrate seamlessly into any of our systems.” Its Gyro350 was recently used at the IAAF athletics in Korea and its camball 2 was used to film ice hockey in Germany.

Motion Control

David Bradley, who runs remote control specialist Bradley Engineering, is building smaller cameras to emulate bigger ones and remote cameras to emulate manned cameras. “To address this we invest heavily in R&D to ensure we stay ahead of the competition and

Boxx TV is promoting its portable point-to-point microwave link as an alternative to fibre. Dubbed Cerulean, the system uses the underdeveloped, high frequency band 60Ghz which has a transport latency below 2ns, similar to the performance of fibre optic networks. Signals are uncompressed, so there is no encoding delay and one version supports all HD formats. Tests have shown that it operates

at up to 500m. “We designed Cerulean for critical acquisition applications, primarily OB and sports,” said Boxx TV CTO Scott Walker. “It can be set up in under five minutes. All you have to do is plug the boxes in, tilt the transmitter and receiver to line them up, and it will work anywhere in the world.” Sony’s first professional integrated camcorder, the shoulder mounted PMW-TD300 is also shipping with an optional wireless link permitting remote control by MPE-200 processor. Devised by Broadcast RF, the link will make pitch side steadicam action more feasible, and is something that Panasonic does not yet offer. Presteigne Charter made the first purchase in Europe of this unit and will put the RF functionality to test. According to Sony’s head of 3D and Sports Solutions Mark Grinyer: “By using the link the camcorder effectively looks to a convergence operator in a OB truck as if it were a 3D rig. This is something that live 3D sports productions in particular have been crying out for.”

Hi-speed

There are three dilemmas that need to be solved before hispeed cameras will play more than a periphery part in outside

broadcasts. These are a simplified workflow which matches that of standard broadcast camera operation; a better image quality with a higher dynamic range and better noise-to-signal ratio and an enhanced light sensitivity. The main vendors - NAC/Ikegami, I-Movix and Live Motion Concept are working towards all three with an eye to deployment at London 2012. A software upgrade to I-Movix SprintCam Vvs HD includes some interesting features such as a True Rec 709 Gamma and a black gamma, new detail enhancements, a matrix control with a 709 and EBU matrix and a brand new colour temperature setting. “Because of the single CMOS sensor of our hi-speed cameras, our customer’s need were about matching their imaging capability with other cameras in terms of noise reduction, flare reduction and so on,” says company CEO Laurent Renard. “We also developed an automatic calibration that makes your camera available in a snap from the paint box.” The SprintCam Vvs HD, built on a Vision Research camera, operates at frame rates up to 2,700 fps in 1080i50 or up to 5,800 fps in 720p60 (200 times slower).
