  1. As at July 2014; http://www.sony.com.au/productcategory/bravia-lcd-tv in the specifications shows that their TVs are capable of DVB-T2 reception which makes nearly double the data rate of our current DVB-T transmissions. In the UK they show 5 full HD programs from a single transmitter using DVB-T2 although this is helped by the fact that they have 8 MHz wide channels and ours are 7 MHz wide. Sony have been installing MPEG-4 decompression in all of their TVs since 2010. The other manufacturers do not mention DVB-T2 or the decompression types available in their specifications. Alanh
  2. http://www.uec.com.au/au/index.php/products/newvastproducts/idtv22inch shows a Full High Definition TV containing a satellite receiver. It includes a PVR to record programs. It will also operate from 12 V DC The also make a larger TV but it is only HD not Full HD. Alanh
  3. Curious if anyone knows/has this experience. Two callers today on my radio show noted issues with fast forwarding on recordings on their PVR on the new 9HD Mpeg-4 channel. Curious if anyone knows if this is DRM related, is fast forwarding something that MPEG-4 broadcasting can prevent? Or is this more likely a case of PVRs getting confused by the recorded content and failing to FF when requested? I have NFI! TL
  4. Mobile phones: Telstra is switching off GSM = 2G on 1st December this year and Optus on 1st April next year followed by Vodafone in September. If they can switch off this equipment why can't the broadcasters switch off MPEG-2 and then provide 2 or 3 full HD programs per broadcaster. Well over 90 % of TVs can display HD programs. What is unknown is the number of these receivers which cannot receive MPEG-4 signals. A review of 7fix ratings on http://oztam.com.au from before and after the change from MPEG-4 to MPEG-2 had made no difference to the percentage of viewers if the period of additional promotion at the changeover is excluded. So channel 7's fear that it was MPEG-4 was the cause of low ratings is a falacy. During the switchover to digital all full time pensioners were able to be provided with a free STB which is HD MPEG-4 capable. It's about time that all primary program channels eg 2, 3, 5, 6, 7, 8, 9, 10 were switched to full HD on MPEG-4 and for a year channels 20, 30, 50, 60, 70, 80 and 90 show an identical program in low data rate MPEG-2. (This overcomes the problem that many present viewers do not know to select channels 30, 60, 70, 80, 13 instead of 3, 6, 7, 8, 9). At the same time an additional full HD MPEG-4 channel of the broadcasters' choice be also transmitted in full HD such as One ABC 2, SBS 2, 7Mate, Gem. After the year of simulcast the SD program should be switched off and replaced with the broadcasters' 3rd program but upgraded to full HD. As can be seen by the Oztam ratings, the ratings of the secondary channels individually is very low. Considering that MPEG-4 technology is now 10 years old, the Australian standard for receivers AS4933 should be upgraded to include HEVC = h.265 compression xHE-AAC sound compression and DVB-T2 in all new TVs for an orderly transition to UHD TV in the future. This is an orderly plan just as Telstra, Optus and Vodafone are using to shut down old technology. Alanh
