As the proposed bill is currently worded, a new TV set would not be compatible with your current home audio stereo. Because all new TV sets would be prohibited from having any analog outputs, you'd have to replace not only your TV set, but your entire home audio system, too!

The next challenge was to develop a technical blueprint that would take advantage of the latest technology and techniques to cover existing needs and anticipated future growth. More than 20 years of origination expansion had gradually progressed via a series of individual channel investments. In the new facility scenario, a shared infrastructure made great sense, but how were the individual channel technical requirements to be best served? Find- ing the right combination of shared vs. dedicated technical components emerged as the key design consideration. The design team aimed to configure and size the underlying infrastructure to achieve economies of scale, while also tailoring the rooms and spaces to meet the differing needs of each channel.

As our signals move increasingly to- wards compressed signals where the essence is simply data, it is hard not to see such a movement being a logical extension of the injection of data techniques in the signal path.

Asynchronous data streaming

Non -streaming synchronized data The protocol can detect transmission errors in the data it carries, since the DSM-CC sections employed include a CRC/checksum field for that purpose. The data carousel sends (and repeats) data at intervals to obviate a flow -control system, as well as repetitions for error protection. Figure 2 illustrates the headend infrastructure. The non -flow - control scenario embodies the unidi- rectional, one-time transmission of a bounded data image to a data receiver. The data carousel cyclically repeats the contents of the carousel one or more times. If a data decoder wants to access a particular module from the data carousel, it can simply wait for the next time that the data for the requested module is broadcast.

Avid Dear Reader

As it has from its beginning a half century ago, TV news will continue to benefit from technological developments. New technology brings competitive advantages and operating efficiencies. NEWSOURCE One of the primary editorial missions of both Broadcasting & Cable and Broadcast Engineering magazines has been to provide television executives with the information they need to incorporate these developments e LEITCH into their operations. It is clear that today, choosing the right technology is crucial to the success of a station or network news operation. This News Technology Supplement is a special project focusedon educat- ing television station and network owners, management and engineering talent on the opportunities and challenges presented by the latest techno- PATHFIRE. logical developments. Enabirng DigitalMedia Operating efficiencies can improve news coverage, enrich program content, gain viewership through more effective news programming, and bring a greater return to the bottom line. This supplement reflects a News Technology Summit held October 16th and 17th in Atlanta. More than 80 television executives joined 12 leading ri,N,NTAET, equipment providers to discuss, explore and find solutions which will improve their news products. We hope this special effort provides insight that is helpful to the readers of both magazines, as they strive for more compelling coverage coupled Sgt with operating efficiencies.

Today, ROI is tangible efficiencies controlling servers, cg's, perhaps the most critical basis for equipment and other devices that could be linked to a purchases, and we believe that no other story slug in the producer rundown.
