EUREKA 147
There is such a thing as being TO unique. So different that you make a
nusece of yourself and make it hard for you to be with and around others. For some its my uncultured posts and poor spelling that makes me to different. In the case of a country its very dangerous and bad to productivity and to leads to massive job loss and inconvience when trying to trade or do business with them. After a while its better to just throw up your hands and say forget it. NOW how in the world does this have to do with radio broadcasting. Well there is a correlation. There is only 2 countries in the world who choose not to use the same broadcast standard for digital radio. Ironicaly there is also only 2 nations that dont use the metric system. We will use metric as the most widely known and used example. This simple neglect in the metric system has cost jobs, lives, compromised safety and done so much in so many little ways its unmeasurable. For keeping this post short I leave that as comment to set the stage and give a description of Eureka 147. Heres how eureka 147 works and what I am talking about. EUREKA 147 DAB The Eureka 147 DAB system is based on MPEG Layer-2 as source coding scheme. During the development one of the goals was to achieve "CD quality" audio quality. Therefore the target bit rates for one audio program should be between 192 and 256 kbps. for broadcasting in the DAB system. The lack of frequency and the necessity to offer additional audio services compared to the existing selection of services on analogue FM broadcasting has lead to a reduction of the average bit rate. In the UK, which is currently the most successful DAB market, most services are today transmitted with a bit rate of 128 kbps for a stereo service. And still the broadcasters and network operators are looking for additional options to reduce the bit rate even further. Isnt it interesting that only the usa and japan (technically part of the usa) dont use eureka 147. Like metric this will make us hard to deal with. Its like being the only openly gay guy at a southern baptist convention meeting. I mean we dont use metric, the cost of this has been jobs and trade. Many metric nations forbid the use of non metric measure on labels and in production. This is so shipping weights can be reasonable and calculated and sizes can be unifrom. SAE measure has its own uniformity that is not concurrent to metric so trying to trade with a metric nation can be dicey. Now the world will not stop if we dont use eureka 147 in the united states but it will isolate us in yet another way. It goes back to my first assertion how different do we have to be to be so unhelpful to our national neighbours its easier NOT to deal with us? fair use invoked for private demostration purposes and reduction of internet duplication of improper and inaccurate information copy from http://www.broadcastpapers.com/radio...odingSBR06.htm page for non orginial fair use material. |
