The invention is concerned with insertion of secondary content in a time slot of primary content. The primary content and the secondary content are provided to a receiver via a managed content delivery network configured for IPTV delivery. The secondary content may be personalized content, such as an ad. Both the primary content and the secondary content may be encrypted, and decryptable with different decryption keys. Measures are described for pre-caching the decryption key for the secondary content at the receiver ahead of a scheduled play-out time of the secondary content. By pre-caching the decryption key, an interruption in play-out may be avoided or reduced compared to a basic scenario in which the receiver requests the decryption key at or immediately before the scheduled play-out time.

Inserting secondary content in primary content in IPTV

A user device () may be arranged to control insertion of personalized content into multicast content. The user device may be arranged for sending a request to a personalized content provider system () and receiving personalized content in response to the request, and may further be arranged for storing a personalized content token (). The request for personalized content may only be sent if the user device stores a personalized content token. In an embodiment, the request for personalized content may only be sent if the user device stores a personalized content token having at least one predetermined property.

Personalized multicast content

Method and systems for enabling low-latency streaming of segments over at least one network to a client are described wherein said client is configured to request and receive segments from at least one server on the basis of a manifest file. Said method comprises: collecting quality of service information experienced by said client in at least a part of said network and storing said quality of service information in a quality database in said network; sending at least part of said quality of service information to said content processing device; determining on the basis of said at least part of said quality of service information one or more configuration parameters for a buffer, preferably a play-out buffer; and/or, for a segment request function in said content processing device; and, configuring said buffer and/or, said segment request function in accordance with said configuration parameters.
