This solution finder is aimed at helping you locate a suitable product to meet your requirements....

If you need to send programme (audio content) in real time from one location to another, you need to have some suitable connection scheme. The device that interfaces the audio equipment to the communications medium is called a CODEC - short for EnCOder/DECoder. For broadcast sound work - especially when a low-delay is required, a special range of algorithms has emerged and has been integrated within equipment designed to interface studios and routing systems. Broadcom offers an extensive range of professional codecs.

ISDN is the long established means of establishing 'live' audio links. These have been used very successfully for outside broadcasting, occasional contribution links and as back-up paths for studio to transmitter links. Broadcom was involved in ISDN connectivity from the outset providing several solutions, and still offers several ISDN-based products.

With the advent of IP connectivity via computer networks and the internet audio links may be established over this medium easily and conveniently. However, whilst company-wide, managed networks can be made to work very well when correctly designed and configured, using the internet for real time audio connections has had mixed success. For a single stream path, the internet medium is very prone to packet delays and losses which will vary depending on the network conditions. In short, effects such as audio drop-out and strange noises may occur, rendering the link unusable for professional applications and that is where the APT SureStreamer unit comes in.

Broadcom offers a range of Audio over IP Codecs (AoIP) for various applications plus APT WorldCast Systems "SureStreamer" product which significantly improves IP connections via the internet (ADSL). So look over our list below, explore our products, and if you need any help in choosing, don't hesitate to give us a call.
