Internal workings of a HD receiver ?

[TexRedNK]

Hi Guys, Retired electronics guy here who serviced analog TVs back when they used 'hollow-ware' (Vacuum Tube) technology. Is there a book or www site where I can learn how to trace a HDTV signal from the antenna thru the various conversions inside the HD receiver and finally to the HDTV monitor ? Just a block diagram would help a lot !
Thanks in advance, Doug
