Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] figure 1 is a flow chart of the EPG update method in one embodiment. like figure 1 As shown, the EPG update method includes the following steps:

[0022] S10: When the version of the EIT table changes, determine the corresponding updated channel and EPG event according to the new version of the EIT table whose version has changed.

[0023] Each channel EPG event list is transmitted by multiple EIT (Event Information Table, ie event information table) tables. When the EPG event is updated, the version of one or more EIT tables changes, and the changed EIT table will transmit the new EPG e...

Abstract

The invention relates to an EPG (Electronic Program Guide) updating method and system. The method comprises the steps of: updating and replacing an EPG event transmitted in an old version in a channel EPG event list by an EPG event transmitted in an EIT (Event Information Table) with the version changed, and establishing two buffer regions to cache the EPG event lists in old and new versions; updating the old EPG event list in the buffering regions, and then updating an display interface. As all the EIT are not received again for updating after all the EPG event lists are deleted, and one EIT is not updated once being finished, the problem of causing incomplete EPG events is avoided, great inconvenience cannot be brought to a user for looking up, and the condition of frequent screen refreshing of the interface is avoided, and the information of the EPG events are facilitated to be watched by the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to an EPG updating method and system. Background technique [0002] At present, when using an audio-video terminal (such as a TV set, a set-top box, etc.) to watch a TV program, the events of each channel can be checked through the EPG (Electronic Program Guide, Electronic Program Guide) event list of each channel. [0003] Each channel EPG event list is transmitted by multiple EIT (Event Information Table, ie event information table) tables. When the EPG is updated, as long as there is a change in the version of the EIT table, all the EPG events of the channel will be deleted, multiple EIT tables will be received again, and the EPG event will be parsed from the newly received EIT table to generate a new one. List of EPG events. Since it takes a certain amount of time to receive multiple EIT tables, if you check the EPG event list at this time, you can only see the EPG event of t...
