Description

technical field [0001] The invention relates to video-on-demand technology, in particular to a video-on-demand method and system based on live recording. Background technique [0002] At present, the process of the video on demand method based on live recording is as follows: figure 1 As shown, the method includes the following steps: [0003] Step 101, the program production division records live programs according to the original program list, and stores the media files of each program. [0004] The original program list is a pre-set program list before the live broadcast. The original program list mainly records the start time, end time, channel and program name of each program to be played. In this step, the live program is recorded according to the program list. [0005] Step 102, the program production division publishes the original program guide to the electronic program guide (EPG, Electronic Program Guide), and the set-top box displays the EPG to the user.

AI Technical Summary

Problems solved by technology

[0008] The information of each program contained in the original program list is pre-recorded information about the live program. Due to the suddenness of the live program, it may not be possible to play according to the original program list during the live broadcast process. For example, according to the original The actual program recorded in the program list has many advertisements and other titles, which leads to inaccurate start time of the program recorded in the original program list; The cutoff time for the show is inaccurate; as another example, some shows on the original playlist may have been canceled, resulting in an inaccurate record of the show on the original playlist

Since the program information recorded in the original program list is inaccurate, correspondingly, the program information recorded in the EPG displayed to the user in step 102 will be inaccurate

[0009] Moreover, in step 103, the user browses the EPG to search for the program requested to be played. Since the program information displayed by the EPG in the prior art is not classified, it is inconvenient to search and increases the user's search workload.

[0010] In summary, the existing video-on-demand method based on live recording has the following disadvantages: the program information displayed through the EPG is inaccurate, and the classified program information cannot be provided, making it inconvenient to find the desired program
