Time Adjustment System and Time Adjustment Method for Electronic Program Guide

摘要

A clock information correction unit 15 is provided to correct the broadcast start/end times of an electronic program guide (EPG) generated in reference to the standard time. To perform this correction, the clock information correction unit 15 uses the standard time, which is the Greenwich Mean Time received by a standard time reception unit 11 of a broadcast reception device 100, and the clock time counted by an internal clock 21 of a head unit 200. The aforementioned correction is made based not on the time difference between time zones, but on the clock time of the internal clock 21. Thereby, without time zone setting based on GPS positional information or selection by a user operation, the broadcast start/end times of the EPG can be adjusted to correspond to the time of the internal clock.

主权项

1. A time adjustment system for an electronic program guide (EPG) comprising:
a standard time acquisition unit configured to acquire a standard time, wherein the standard time is a Greenwich Mean Time; an EPG acquisition unit configured to acquire an EPG in reference to the Greenwich Mean Time; a clock time acquisition unit configured to acquire a clock time, wherein the clock time is a time counted by an internal clock; and a clock information correction unit configured to use at least the standard time acquired by the standard time acquisition unit and the clock time acquired by the clock time acquisition unit and correct broadcast start/end times of the EPG acquired by the EPG acquisition unit.
