No. A standard (non-HD) Freeview tuner cannot take an incoming HD broadcast and convert it to SD. SD is broadcast using the DVB-T standard. HD uses the DVB-T2 standard. An SD Freeview box can handle only DVB-T (SD) material. It will ignore DVB-T2 (HD) stuff. It has no means of "decoding" it. See also David's reply. -- Peter Duncanson (in uk.tech.digital-tv) |

You are confusing two issue here -- tuning and decoding. A standard SD Freeview receiver does ignores the DVB-t2 transmissions because it cannot receive the DVB-t2 format of the transmission. It is only after the signal has been processed by the tuner that the HD multiplex video stream encoded in MPEG-4 (h.264 codec) is decoded. So to summarize: Freeview SD is DVB-t transmission with MPEG-2 encoding. Freeview HD is DVB-t2 transmission with MPEG-4 encoding. Other European countries current broadcast terrestrial HDTV with DVB-t transmission but MPEG-4 encoding. Saorview uses this format for both SD and HD transmissions. http://www.saorview.IE |

It keeps people in jobs making new ones. It is somewhat alarming. If we were, as individuals and as a society, to cut back on purchases that are not strictly necessary to life there would be mass unemployment worldwide. -- Peter Duncanson (in uk.tech.digital-tv) |
