In various embodiments, a unidirectional broadcast network is utilized to provide digital content to users in a manner that allows users' computing devices to maintain synchrony with personal, relevant information. In at least some embodiments, the broadcast network utilizes a data channel and a signaling channel. The data channel is used for broadcasting data to various users, while the signaling channel—typically used for transmitting device or machine specific data—is used to transmit user-specific information associated with the information or data that the user finds relevant. This user-specific information can then be used by the user's mobile computing device to manage, e.g. record and place into device database for time shifted retrieval, such information or digital objects delivered over the broadcast data channel.
