Some interesting info on the DST biz which I think might sneak into a very prominent position for mindspace later this year...this is a portion cut and pasted from a white paper at www.louth.com Louth Automation was mentioned in the PBS announcement last week... "Distributing the processing intelligence, I/O, and media storage has the benefit of minimizing exposure to catastrophic failure but relies on external applications to control and manage movement of material into ready-to-play status. In larger installations containing multiple servers, the management of media can become rather sophisticated, such as in a peer-to-peer mode. Two of the most widely installed networked broadcast servers under Louth control are the Tektronix family of PDR Profiles and Hewlett-Packard MediaStream Broadcast Servers. Based on current shipping product, the JPEG versions of Profiles (PDR100 and 200) support up to four simultaneous channels (record or play). The PDR300 MPEG 4:2:2 Profile supports up to eight simultaneous channels with a maximum of two encoders per chassis. Currently, the Tektronix PDR400 series offers compatibility in DVC format aimed at news applications. The HP Servers are also MPEG-4:2:2 and can be configured with up to 6 channels with as many as four encoders. This makes it a good choice for certain program acquisition applications requiring several simultaneous recordings. Both products use high-speed Fibrechannel to create clustered networks with decentralized storage. This allows systems to scale linearly to very large numbers of channels. Of course, media may have to be transferred from one server to another depending on where it is needed. For example, Fox Digital's new network origination center in Los Angeles is the first major network to go tapeless. Under Louth control are over 30 PDR200 and PDR300 systems connected on Fibrechannel networks. All programs are stored on Ampex DST archival tape and are transferred into program servers feeding on-air buffers. Each DST cartridge stores an entire season of syndicated 30-minute programs- typically 26 or more. The network's entire commercial library is stored exclusively in redundant 30-hour RAID servers also feeding on-air buffers. This system allows FOX total flexibility in media movement. As a result, FOX can readily broadcast to multiple regions and subregions simultaneously, with commercial breakaways pinpointed to select markets. New capabilities developed for FOX allow multiple lists to be linked, facilitating the editing and management of multi-channel lists. This is particularly valuable for live sporting events where as many as nine or ten control rooms may operate concurrently-each with the ability to provide regional commercial inserts." Also, I would suggest the key idea in the Aentv annoucement was the "syndication" of video content to other sites...like if Yahoo wants to begin adding video content to their site..instead of producing it themselves..buy the programming already in the can and on the web...
