| 摘要 |
In certain embodiments, a digital television receiving method that receives non-real time (NRT) content involves receiving a transport stream containing an Internet Protocol (IP) stream of packets containing non-real time content, NRT service metadata and NRT content metadata; at a demultiplexer, demultiplexing the IP stream of packets to produce: NRT content that is stored in the electronic storage medium, NRT service metadata, and NRT content metadata; parsing the NRT metadata to produce NRT service metadata, and NRT content metadata; and where the NRT content metadata contains a signal that indicates that an update is available indicating whether or not a referenced content item will be updated periodically. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract. |
