In the 70s and 80s, broadcast quality video recording was done on large and heavy equipment - 'high band U-matic'?.
U Matic was only allowed (within ITV and C4) for news acquisition  The IBA Code Of Practice did not allow its use for non news applications. Electronic cameras on location had to have their output recorded by Quadaplex (2
) or C or B Format, (1 inch VT). Although some programmes such as ATV's Timeslip, and the BBC coverage of the RI Lectures used an OB truck producing the footage as a multicamera shoot, but sending the footage back via microwave link to the studio centre for recording there, rather than attempting to bring the VTR to site.
 Almost certainly the BBC applied the same standards. The IBA did apparently allow Channel TV to use U-matic to timeshift their showing of Crossroads in the 1980s.
Not quite the same at the BBC - the BBC "Film Unit" certainly had HiBand Umatic recorders and 3-tube lightweight cameras for some acquisition in the 80s (the bizarre duopoly of Film unit video vs BBC OBs single camera operations was part of the reason), as did BBC Outside Broadcasts. UMatic HiBand stuff would usually be edited to 1" (C-format usually at the BBC) - and the BBC "Film Unit" also had some early (non-SP) Betacam stuff (the first real camcorders)
The workhorse of BBC OBs PSC (Portable Single Camera) operations was - by the mid-80s - the Ampex VPR5 (which took small 1" spools and looked like a Nagra sound recorder with 1" rather than 1/4" tape - and a Sony BVP-330AP - where UMatic wasn't deemed acceptable. (The VPR 20 was also used)
There wasn't a straight News/Non-News demarcation as such in the BBC - and whilst UMatic was frowned-on, it was certainly used for non-News shows. (News were probably the only people who did 2m/c UMatic edits though)
And of course loads of us remember watching Treasure Hunt - where Aneka's location stuff was recorded on a very visible UMatic recorder!
