The present technology relates to a data processing apparatus and a data processing method capable of achieving higher convenience in a case where a plurality of transmission formats is available in a transmission frame. The data processing apparatus installed in a transmission-side facility processes a transmission frame transmitted as a broadcast signal and adds identification information for identifying the transmission format of the transmission frame, while a data processing apparatus installed in a reception-side facility processes a transmission frame in which a transmission frame has been identified, on the basis of identification information added to the transmission frame transmitted as the broadcast signal. The present technology can be applied as a method of a test stream, for example.

A system (1000) is disclosed including a resource allocation optimization (RAO) platform (1002) for optimizing the allocation of resources in network (1004) for delivery of assets to user equipment devices (UEDs) (1012). The RAO platform (1002) determines probabilities that certain asset delivery opportunities (ADOs) will occur within a selected time window and uses these probabilities together with information concerning values of asset delivery to determine an optimal use of asset deliveries. In this regard, the RAO platform (1004) received historical data from repository (1014) that facilitates calculation of probabilities that ADOs will occur. Such information may be compiled based on asset delivery records for similar network environments in the recent past or over time.

A vehicle messaging method (600) and system (100) can include any number of data sources (101-103), an interface (104) that formats messages and addresses from the data sources, and a corresponding number of messaging servers (111-113) that receive targeted messages intended for a predetermined subset of subscribers associated with a vehicle identification number (VIN). Each messaging server can include a corresponding controller (121-123) programmed to assign (604) targeted messages to a predetermined channel and encode (606) the addresses of the targeted messages to the predetermined subset of subscribers using a VIN or portion thereof. The controller can be further programmed to transfer (608) the targeted messages and addresses to a satellite uplink (107) and satellite (110) via a messaging uplink interface (106) for retransmission and reception by a plurality of selective call receivers 109 addressable individually using a predetermined VIN or portion thereof.

A method and apparatus are provided for generating a personalized radio channel playlist by simultaneously buffering multiple received channels from one or more source streams, and then selecting songs or tracks to playback from the buffered channels. Users can specify favorite channels for building their personal playlists, or multiple default playlist channels can be provided by genre or channels related in some other way. Navigation tools permit users to skip ahead and backward in the playback stream. A personalized radio channel playlist can be implemented as (1) content selected from buffered channels based on user preferences for artists, songs and the like, or (2) as a Mix Channel in which content from selected buffered channels is automatically mixed for playback in response to selection of a preset button assigned to the Mix Channel.
