Method and apparatus for updating reservation recording channel number

Abstract

The embodiment of the invention provides a method and apparatus for updating a reservation recording channel number. The method comprises: on the basis of a first channel number carried by a received reservation recording request, parsing is carried out on a code stream to obtain first channel efficacy information corresponding to the first channel number, wherein the channel efficacy information includes an original network identifier, a transmission stream identifier and a service identifier; before starting of a recording event corresponding to the reservation recording request, if a channel list execution updating operation is detected, parsing is carried out in a current code stream to obtain second channel efficacy information corresponding to the first channel number based on the first channel number; and if the first channel efficacy information is different from the second channel efficacy information, traverse of an updated channel list is carried out and a second channel number consistent with the first channel efficacy information is searched. Therefore, a problem that a recording error or failure may be caused by channel list updating when information like the channel number is used as identifier information of PVR recording and thus the user experience is affected is solved.

Description

technical field [0001] The embodiment of the present invention relates to the field of stream recording, and in particular to a method and device for updating channel numbers for scheduled recording. Background technique [0002] With the development of digital TV, users have increasing requirements on the functions of digital TV set-top boxes, and more and more TVs or set-top boxes have added PVR (Personal Video Recorder, personal video recording) service function. Scheduled recording is the most basic functional component of PVR service functions. Other functions such as time shift, video recording, rewind, fast forward, and pause, etc., bring digital splendor and interactive freedom to users. Therefore, providing more humanized services and perfect program reservation play and reservation recording functions are the necessary driving force for technical improvement in the field of PVR technology. [0003] The scheduled recording in the current PVR service is usually impl...

[0004] However, if the user updates the channel list between the time when the user enters the scheduled recording request and the start time of the scheduled recording request, for example, operations such as re-searching channels or editing and sorting channels, the channel list may change, for example, The channel number of the reservation request is adjusted from channel number 2 to channel number 3, which causes the PVR to start recording on the wrong channel, or because the program that is consistent with the recorded identification information cannot be found, for example, the desired recording cannot be found from channel 2 The name is "Today's Saying" program, so the recording failed. That is to say, in the prior art, information such as the channel number is used as the identification information recorded by the PVR, which may cause recording errors or failures due to the update of the channel list, affecting user experience.
