These two PDFs are hard to find on the internet, and were hosted on the old SAGE website. They're useful for technical delivery standards, as well as an up-to-date logo design source. If you have more recent documents, please let us know.
SABC Technical Standards for Television Programme Delivery
This PDF is dated 2004, so use at your own risk! SABC delivery is still on Betacam SP, so this may not have changed.
SABC Visual Identity Standards
This SABC logo brand bible has a creation date of October 2008. It is useful if you need a vector version of the current SABC logo, easily retrieved from this PDF using Illustrator.
