The embodiment of the invention discloses a method and terminal for reporting sensor data. The method for reporting the sensor data includes the steps that when a processor only needs to process the sensor data collected by a sensor, the processor sends an instruction of going to sleep and goes to sleep; after the processor goes to sleep, a sensor concentrator receives and temporally stores the sensor data collected and reported by the sensor to an event information table, records corresponding time when the sensor data are collected by the sensor and temporally stores the time in the event information table; after the processor recovers the working condition, the sensor concentrator reports the event information table to the processor, and the processor analyzes the event information table and completes corresponding processing. When only the sensor works, the processor is in the sleep state all the time, the low-power dissipation sensor concentrator temporally stores the data, and therefore the overall power dissipation can be saved.

A master guide table for a digital broadcast protocol, and a method of broadcasting and updating an electronic program guide using the table, uses identification information included in a bit stream syntax of the master guide table to classify whether contents of an event information table are merely shifted in time, or are actually changed. The master guide table is transmitted in accordance with a program and system information protocol (PSIP) for an advanced television system committee (ATSC) defined standard digital television broadcast protocol. A digital television receiver of a receiving party, or a digital cable broadcast receiver, can determine whether the contents of the event information table EIT are merely shifted in time or actually changed by parsing the identification information in the master guide table MGT. If the parsed contents of the identification information indicate that the event information table contents are merely shifted in time without any change, then a database maintaining previous event information table is not updated. Accordingly, time wasted in unnecessarily updating the database can be decreased.

Example apparatus and methods concern selectively accepting or rejecting content based on ratings identifier information included in the content. Example apparatus and methods facilitate identifying a content fragment (e.g., f-MP4 fragment) to be rejected based on an identifier located in the fragment rather than information located in some external source (e,g., Event Information Table (EIT)). One example method includes identifying a fragment based on a ratings identifier encoded as a universally unique identifier (UUID) in the fragment and then selectively accepting or rejecting the fragment based on the rating. Rather than rely only on a predicted start time, a predicted end time, a predicted source, and a pre determined coarse-grained rating, example apparatus and methods may be better prepared to account for unanticipated start times, ending times, schedule changes, and source changes, and may provide finer grained user control based on ratings carried in content.
