Sherlock co-creator Steven Moffat has been honoured with a writing prize at this year's Bafta Craft Awards.
A Scandal in Belgravia, the opening episode of the BBC One drama's second series, was also recognised for its sound and editing at Sunday's ceremony.
Dickens adaption Great Expectations and wildlife documentary Frozen Planet also won three awards at the event, which recognises behind the scenes talent.
Moffat said he was "genuinely, utterly thrilled" by his latest accolade.
Frozen Planet was also honoured for its sound and editing and picked up an additional prize for photography.
The BBC One series faced criticism last year after it emerged that footage of newborn polar bear cubs featured in the programme had been shot in an animal park.
Great Expectations' awards came for its production design, visual effects and photography and lighting.
The three-part period drama had led the field prior to this year's ceremony, with nominations in seven categories.
Held at the Old Truman Brewery in east London, the event also saw recognition for ITV1's Appropriate Adult, BBC war drama Birdsong and Channel 4's Educating Essex.
Former Roxy Music star Brian Eno picked up his first Bafta for his soundtrack to gang thriller Top Boy, while colourist Aidan Farrell received a special award for his contributions to such shows as Wallander and Downton Abbey.
The main Bafta TV awards will be presented at a ceremony in London on 27 May.
Appropriate Adult, ITV1's dramatisation of the investigation into serial killer Fred West, is the front-runner, with four nominations.
Sherlock and Channel 4 drama This Is England '88 also have three nominations each.
And Australian entertainer Rolf Harris will be awarded the Bafta Fellowship.
