From a letter someone sent me from someone who works there:
"have you noticed in the media the increasing number of reports on SA adopting the Japanese digital TV standard (ISDB-T). SA, being part of Region 1 adopted the DVB family standard for digital terrestial TV that is about to be launched. Millions have been spent on DTT Tx with the DVB standard capabilities, which is based on 8MHz channel bandwidth, whereas ISDB-T is 6MHz. I don't think I need to explain any more to you as this alone shows that we cannot now change from the DVB standard, as not only is ISDB less sophisticated than DVB, but it means that the entire spectrum plan has to be re-co-ordinated with all our neighbouring countries who have adopted the 8MHz channel spacing of DVB, which will take several years.
Amidst Sentech's woes it is planning on a fact finding tour to Brazil, Columbia and Japan. We are convinced that the following is behind this sinister plot: the Japanese have bribed the government that if they change to and adopt the ISDB standard, which means the set-top boxes will be imported from Japan and new Txs will come from ............"HITACHI", then Chancellor House will get a few million back-handers that will grow to billions for the party as has already happened with the power station deals. You may think I have lost my marbles, but this is about the only "rational" explanation because there is otherwise no compelling reason (technical or other) to adopt the Japanese digital TV standard, which is beyond all doubt inferior to the DVB standard, and what's more DVB standard decoders are cheaper than ISDB, because it has more market share and hence the chipsets are now cheaper.
What SA now needs to decide is to start its DTT transmissions on the DVB-T2 platform as this is even more superior than its predecessor (DVB-T) as it uses 256QAM modulation which permits over 30MB bitrate and this in turn allows several HDTV channels instead of only 2 as with DVB-T, which uses 64QAM. DVB-T2 is the most elite digital scheme on earth at the present time.
We can see this whole crazy debacle being taken to the Constitutional Court by the multimedia industry of SA as it affects EVERYTING related to TV, including the broadcasters. The drive to adopt another standard is being driven from parliament!!!!!!!!!
