A method of receiving and process a broadcast signal including a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing a broadcast signal including a Non-Real Time (NRT) service, the method comprises receiving and processing a signaling information table including access information of the NRT service, receiving and storing data of the NRT service based on the signaling information table in non-real time, extracting access information of additional information relating to the NRT service from the signaling information table, and downloading the additional information relating to the NRT service based on the extracted access information.

A plurality of digital video recorders are polled to extract data indicative of recordings scheduled thereon. The polling is carried out over a video content network by a component at a node in the video content network that is remote from the plurality of digital video recorders. At least a portion of the data is used to obtain a prediction of future switched digital video channel usage for the video content network. At least one network management activity is carried out on the video content network in response to the prediction of future switched digital video channel usage for the video content network.

An information processing device includes a broadcasting apparatus broadcasting a content at a predetermined transmission rate to at least a receiver downloading the content and a generating unit, generating metadata for the content. The metadata contains download-rate state information indicating a state of the predetermined transmission rate with respect to a reproduction rate at the receiver. The broadcasting apparatus further broadcasts the metadata generated by the generating unit.

Handover of broadcast audio/video content from a first/source device via an intermediate device to a second/destination device. The intermediate device is set up to receive by its own means the same broadcast audio/video content as received by the first/source device. If interruption of play out of the audio/video content by the first/source device is detected by the intermediate device, the intermediate device stores the received audio/video broadcast in timeshift memory. When a presence of the second/destination is detected, the intermediate device connects to the second/destination device and starts timeshifted streaming to the second/destination device.

The present invention provides a method of transmitting broadcast signals. The method includes, formatting input streams into Data Pipe (DP) data, Low-Density Parity-Check (LDPC) encoding the DP data according to a code rate, bit interleaving the LDPC encoded DP data, mapping the bit interleaved DP data onto constellations, building at least one signal frame including the mapped DP data, and modulating data in the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) method and transmitting the broadcast signals having the modulated data, wherein the input streams include Audio/Video (A/V) data and service guide data, and wherein the Audio/Video (A/V) data and service guide data are included in first ISO base media file format (ISOBMFF) files.

A method for time dependent replacement of stored broadcast content, wherein such method replaces a time period of broadcast as a function of how many minutes, hours, days, weeks or months have elapsed since the initial broadcast, whether a predetermined date has passed, or according to playback date, the playback day of the week, playback hour or time, or playback proximity to a date, day, hour or time or event of interest.

In one form, the present teachings provide a method and apparatus for broadcasting an event. The method includes receiving data related to an event via an uplink. Another aspect of the method includes determining whether the data is broadcast on a recurring basis. The method also includes determining whether a transponder channel associated with multiplexed program channels has any unused data or bandwidth to broadcast a portion of the data along with the multiplexed program channels. Additionally, the method includes broadcasting the portion of the data in a data stream.
