[0044] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0045] In the prior art, in order to watch the replay program, the user has to operate cumbersomely, resulting in low efficiency in switching between live broadcast and replay. In view of this, the embodiment of the present application provides a method for switching between live broadcast and replay based on IPTV, which is applied to the IPTV system. The following is a brief introduction to the application scenarios to which the technical solution of the embodiment of the present application can be applied. It should be noted that the application scenarios introduced below are only used to illustrate the embodiment of the present application and are not limited. In the specific implementation process, the technical solution provided by the embodiment of the present application can be flexibly applied according to actual needs.

[0046] Please refer to Figure 1 , which is a schematic diagram of an application scenario provided in an embodiment of the present application, or can be understood as an architecture diagram of an IPTV system, and the application scenario includes a set-top box, a remote control and a TV.

[0047] A set-top box is used to receive signals from TV sources (such as cable TV, satellite TV, streaming services, etc.) and convert them into a format that the TV can display. The set-top box also provides additional functions, such as recording TV programs, watching on-demand content, accessing applications, etc. The remote control is used to remotely operate the set-top box. The remote control usually includes multiple buttons such as direction keys, number keys, and function keys. By pressing these buttons, users can switch channels, adjust volume, navigate menus, and other functions without having to directly touch the set-top box.

[0048] As described above, the application scenarios of the embodiments of the present application are described below. Figure 1 Application scenarios Figure 2 A switching method between live broadcast and playback based on IPTV is introduced as shown.

[0049] Combine the following Figure 1 The application scenario shown is Figure 2 A switching method between live broadcast and playback based on IPTV is introduced as shown.

[0050] S201. Play the live program of the target channel on the current interface.

[0051] In the specific implementation process, after the set-top box is connected to the network, it can obtain the live stream of the target channel through the Internet. After the set-top box decodes the received live stream and converts it into a video format that can be displayed on the TV, it transmits the decoded video signal to the TV through an appropriate interface (such as HDMI). The TV displays the received video signal on the current interface, so that the user can watch the live program of the target channel through the TV.

[0052] In a possible embodiment, while playing the live program of the target channel on the current interface, the method further includes: recording the live program in real time to obtain recorded content; and storing the recorded content in a memory.

[0053] In the specific implementation process, the IPTV system can record the content of the live program while playing the live program of the target channel through the TV, and store the recorded content in the memory of the set-top box, such as a large-capacity hard disk or solid-state hard disk. The memory is used to store data for a long time, and the data in the memory is retained even after the set-top box is turned off or restarted. The cache can be cleaned up regularly to free up memory space and ensure stable system performance.

[0054] In an embodiment of the present application, when the user wants to watch the playback clips of the program in the future, they can directly obtain and play them from the memory of the set-top box without the need for the Internet, which can improve the playback efficiency of the playback program. In addition, local storage does not rely on network stability and can usually maintain a high video quality.

[0055] S202: Detecting that the user has pressed the target switch button, stopping the live broadcast on the current interface, and displaying a pop-up window showing the historical dates that can be replayed.

[0056] In the specific implementation process, when the user is watching the live program of the target channel through the current interface of the TV, if the user wants to switch to the replay program of the target channel, the user presses the target switch button on the remote control, which is used to switch between the live program and the replay program of the same channel. At this time, the current interface of the TV will stop playing the live program, and a window will pop up to display the historical date that can be replayed. Among them, the historical date is the date before the current date.

[0057] Considering that the time range for users to actually watch programs is relatively small, it is not necessary to display too many items. In a possible embodiment, in order to optimize the user experience and avoid information overload, the display range of historical dates is set to dates within a preset number of days before the current date. For example, the preset number of days is only 3 days, the current date is 2024.9.14, and the historical dates are 2024.9.13, 2024.9.12 and 2024.9.11. This setting can improve the relevance and practicality of historical dates, help users quickly find recent related content, and avoid displaying too many historical dates, making it easier for users to find content they are interested in.

[0058] In a possible embodiment, the target switching button may be a physical button newly added on the remote controller, or a switching shortcut key preset by the user, wherein the switching shortcut key includes at least one physical button. The following describes the process of the user setting the target switching button.

[0059] During the specific implementation process, the user presses the "Settings" button on the remote control to enter the TV's settings interface, clicks the "Shortcut Key" option in the settings interface to enter the shortcut key settings interface, selects at least one physical button to be set as the target switch button in the shortcut key settings interface, and selects the function performed by the target switch button, such as "switch from live program to playback program" or "switch from playback program to live program". After completing the settings, save the changes.

[0060] In order to avoid interference with the original function of the key, in a possible embodiment, the first physical key of the at least one physical key is a “*” key or a “#” key.

[0061] In the specific implementation process, the target switching key can be a single physical key, such as the "*" key or the "#" key, or a repeated single physical key combination, such as the "##" key or the "*" key, or a different combination of multiple physical keys, such as "#1" or "*2". This design can effectively reduce conflicts with other function keys, effectively isolate new functions from original functions, and avoid confusion and accidental touches in operation.

[0062] S203: Determine a target timestamp according to a target date selected by the user from historical dates and a first timestamp when the live program stops playing.

[0063] In the specific implementation process, when it is detected that the user presses the target switching button and stops playing the live program on the current interface, the current local time of the system can be recorded, that is, the first timestamp when the live program stops playing, and the first timestamp consists of the first date and the first time point when the live program stops playing. The user selects a target date from the historical dates according to the date of the playback program that he actually wants to watch. The first timestamp is split into the first date and the first time point, and the target date selected by the user is combined with the time point to obtain the target timestamp. In other words, the target timestamp consists of the target date and the first time point. Finally, the target playback segment of the target channel is retrieved according to the target timestamp.

[0064] For example, the target date selected by the user is 2024.09.13, the first timestamp is 2024.09.14 12:00, the first date is 2024.09.14, the first time point is 12:00, and the target timestamp is 2024.09.13 12:00.

[0065] S204: Obtain a target playback segment of a target channel according to a target timestamp.

[0066] In a possible embodiment, before obtaining the target playback segment of the target channel according to the target timestamp, the method further includes: obtaining the playback segment of the target channel within a preset time range from the memory, and preloading the playback segment within the preset time range into the cache.

[0067] The step of acquiring a target playback segment of a target channel according to the target timestamp includes: acquiring the target playback segment of the target channel from a cache according to the target timestamp.

[0068] In the specific implementation process, the cache is used to temporarily store frequently accessed data, and the data in it is usually cleared after the application or set-top box is closed, or replaced after the cache expires. While playing live programs, the IPTV system pre-loads the playback clips within the preset time range into the cache. The pre-loading technology can achieve seamless switching from live programs to playback programs, avoiding waiting caused by network fluctuations or slow server response, and significantly reducing the delay when users switch to playback clips. When users switch from live programs to playback content, they can immediately access the playback clips without waiting for loading, avoiding waiting and buffering time, and enhancing the overall viewing experience.

[0069] S205: Play the target playback segment on the current interface.

[0070] In a possible embodiment, after playing the target playback segment on the current interface, the method further includes:

[0071] When a user presses a target switching button, the target playback segment is stopped on the current interface; the target live segment of the target channel is obtained according to the second timestamp when the target playback segment stops playing; and the target live segment is played on the current interface.

[0072] In a specific implementation process, when it is detected that the user presses the target switching button and stops playing the target playback segment on the current interface, the current local time of the system, that is, the second timestamp when the target playback segment stops playing, can be recorded, and the target live segment of the target channel can be retrieved according to the second timestamp and played on the current interface. The second timestamp is composed of the first date and the second time point, and the second time point is later than the first time point.

[0073] For example, if the user wants to switch from the live program of the target channel to the replay program of the target channel, the user presses the target switch button. At this time, the first timestamp when the live program stops playing is 2024.09.14 12:00. The target date selected by the user is 2024.09.13, and the target timestamp of the target replay segment is 2024.09.13 12:00. After watching for an hour, the user wants to switch from the replay program of the target channel back to the live program of the target channel, and presses the target switch button again. At this time, the second timestamp when the target replay segment stops playing is 2024.09.14 13:00, and the target live segment of 2024.09.14 13:00 is obtained for playback.

[0074] In an embodiment of the present application, by operating the target switch button, free switching between live programs and playback programs on the same channel is achieved. Users can switch back and forth between the live broadcast state and the playback state at any time according to their needs and interests, and watch the program at their own pace, no longer restricted to the traditional linear playback mode.

[0075] In a possible embodiment, before obtaining the target live segment of the target channel according to the second timestamp at which the target playback segment stops playing, the method further includes: obtaining the latest live segment of the target channel via the Internet and preloading the latest live segment into a cache.

[0076] The step of acquiring a target live segment of a target channel according to the live timestamp includes: acquiring the target live segment of the target channel from a cache according to a second timestamp at which the target playback segment stops playing.

[0077] During the specific implementation process, the IPTV system pre-loads the latest live clips into the cache while playing the playback program. The pre-loading technology can achieve seamless switching between playback and live broadcast, which can significantly reduce the delay when users switch from playback programs to live programs. When switching to live content, users can immediately see the latest content, avoiding interruptions in viewing due to slow loading of live data, ensuring that users can continue to enjoy live programs, and improving their viewing experience.

[0078] In a possible embodiment, a dedicated live broadcast thread is created to handle the acquisition, decoding, and playback of live program content. This can ensure the real-time and smoothness of the live broadcast content and avoid the quality of live broadcast being affected by other tasks. Another dedicated playback thread is created to handle the decoding, caching, and playback of the playback program content. The playback thread can run independently of the live broadcast thread, thereby ensuring that the processing of the playback task does not interfere with the live broadcast task.

[0079] In the embodiment of the present application, multi-threading technology is used to process the playing tasks of live broadcast and playback at the same time, improve the response speed of the system, and allocate independent threads for live broadcast and playback respectively. When the user switches between playback and live broadcast, the switching process will be smoother and faster because the task processing is independent. Since the live broadcast and playback processing are independent threads, the failure of one thread will not directly affect the operation of another thread, thereby improving the robustness of the system.

[0080] Please refer to Figure 3 , provides a schematic diagram of the architecture design of a switching system for live broadcast and playback based on IPTV in an embodiment of the present application. The switching system for live broadcast and playback based on IPTV includes a data storage layer, a control logic layer, and a user interface layer. The functions of each layer are introduced below.

[0081] At the data storage layer, an efficient storage system is established to save live program data and recorded playback clips. A large-capacity hard disk or solid-state drive can be used to ensure fast data reading and storage. The stored data is classified and indexed to quickly locate specific live programs or playback clips.

[0082] In the control logic layer, a special control module is designed to handle user operation instructions, such as switching live channels, selecting playback time points, etc. A fast switching algorithm is implemented to quickly locate the target segment according to user instructions and perform seamless switching. Interact with the data storage layer to read and write relevant data.

[0083] At the user interface level, an intuitive and concise user interface is provided so that users can easily switch between live broadcast and playback. Clear operation prompts are provided on the user interface so that users know how to switch between live broadcast and playback.

[0084] In summary, the present application provides a switching method for live broadcast and playback based on IPTV. Through reasonable system architecture design, efficient switching mechanism and fast switching technology, the live broadcast interface can be directly operated to switch to the playback program, and the channel content of this time period can be automatically identified. You only need to select the target date to provide users with a more convenient and smooth viewing experience. Users can freely switch between live broadcast mode and playback mode at any time through the target switching button according to their needs, and watch programs at their own pace, no longer restricted by the traditional linear playback mode. Accurate timestamps can help the system manage and retrieve playback clips more efficiently, reduce the waste of system resources, and retrieve playback clips by target timestamps to quickly switch to the playback program and accurately locate it, saving the time of manual search and fast forward and rewind, and improving the switching efficiency between live broadcast and playback.
