UKTV are in the process of moving broadcast playout providers from Redbee to SES, which will allow them to broadcast in HD. Therefore, any commercials previously supplied before the 1st June 2020 and going forward, will need to be resupplied through Adstream/Peach/Clearcast. SES will still be able to ingest SD commercials, although HD should be your preference.
