The DVB Steering Board has given its approval to an update to its Targeted Advertising specifications as well as commercial requirements for the addition of a new CDN-related functionality to DVB-I and DVB-DASH.
The organisation’s specifications on Targeted Advertising come in three parts. DVB-TA Part 1 specifies how advert placement opportunities are signalled in broadcast transport streams, while Part 2 describes the interface with the advertising server. Part 3 focuses on the signalling of ad placement opportunities in DVB-DASH streams.
According to DVB, the latest revision “includes a key annex on what is known as content conditioning, relating to how content should be conditioned in order to maintain period continuity for cases where the ad content does not contain DASH representations that exist in the main content to be substituted.”
Verification and validation work on DVB-TA Part 3 is continuing and the completed specification will then be forwarded to ETSI for publication as TS 103 752-3 V1.1.1.
Continuing its work on the transition to IP- and internet-based delivery of television services through DVB-I, DVB-DASH and other technologies for connected TV, DVB has published details of how CMCD technology can be used with DVB-I to improve the delivery of DVB-I-signalled linear services to consumers.
The commercial requirements, available as BlueBook C109 describe how the CMCD reporting mechanism should be implemented in DASH players when used with DVB-I services.
Common Media Client Data (CMCD) is a new mechanism was standardised by the Consumer Technology Association in September 2022. It gives media players a means of sending back to the CDN information about playback that can be used for optimization and fault finding.
The documents are available from the DVB specification library as BlueBooks.
