[0044] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way. In addition, although a 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, users have to perform complex operations to watch replayed programs, resulting in low efficiency in switching between live broadcast and replay. In view of this, the embodiments of the present application provide a method for switching between live broadcast and replay based on IPTV, which is applied to an IPTV system. The following briefly introduces application scenarios to which the technical solutions of the embodiments of the present application can be applied. It should be noted that the application scenarios described below are merely illustrative of the embodiments of the present application and are not intended to be limiting. During implementation, the technical solutions provided by the embodiments 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. The application scenario includes a set-top box, a remote control and a TV.

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

[0048] The application scenarios of the embodiments of the present application are introduced above. Figure 1 Application scenarios, for Figure 2 The following describes a method for switching between live broadcast and playback based on IPTV.

[0049] The following combination Figure 1 The application scenario shown is Figure 2 The following describes a method for switching between live broadcast and playback based on IPTV.

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

[0051] In a specific implementation, after the set-top box is connected to the Internet, it can obtain the live stream of the target channel through the Internet. The set-top box decodes the received live stream and converts it into a video format that can be displayed on a TV. The decoded video signal is then transmitted to the TV through an appropriate interface (such as HDMI). The TV displays the received video signal on the current interface, allowing users to 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 practice, the IPTV system can simultaneously record live broadcasts from a target channel on a television and store them in the set-top box's memory, such as a high-capacity hard drive or solid-state drive. This memory is used for long-term data storage, and data in the memory persists even after the set-top box is turned off or restarted. The cache can be regularly cleared 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 replay 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 replay program. In addition, local storage does not rely on network stability and can usually maintain a higher video quality.

[0055] S202: Detecting a user pressing 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 a specific implementation, when a user is watching a live program on a target channel through the current interface of the TV set, if the user wants to switch to a replay of the target channel, the user presses the target switch button on the remote control. The target switch button is used to switch between the live program and the replay of the same channel. At this time, the current interface of the TV set will stop playing the live program, and a window will pop up showing the historical dates that can be replayed. The historical dates are dates before the current date.

[0057] Considering that the actual time range for users to watch programs is relatively small, it is unnecessary to display too many items. In one possible embodiment, 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 three, with the current date being September 14, 2024, and the historical dates being September 13, 2024, September 12, 2024, and September 11, 2024. This setting can improve the relevance and practicality of historical dates, helping users quickly find recent and relevant content while avoiding 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 can be a newly added physical button on the remote control, or a switching shortcut key pre-set by the user, the switching shortcut key including 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 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 specific implementations, the target switching key can be a single physical key, such as the "*" key or the "#" key, or a repeated combination of single physical keys, 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 existing functions, and avoid operational confusion and accidental touches.

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

[0063] During implementation, when a user presses a target switch button, stopping playback of a live program on the current interface, the system's current local time can be recorded as the first timestamp of when the live program stopped. The first timestamp consists of the first date and the first time point when the live program stopped. The user selects a target date from the historical dates based on the date of the playback program they actually want to watch. The first timestamp is split into the first date and the first time point, and the user-selected target date is combined with the time point to obtain a 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 based on 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 the 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 practice, cache is used to temporarily store frequently accessed data. This data is typically cleared when the application or set-top box is closed, or replaced when the cache expires. While playing live programs, the IPTV system preloads playback clips within a preset time range into the cache. This preloading technology enables seamless switching from live to playback, avoiding wait times caused by network fluctuations or slow server responses, and significantly reducing delays when users switch to playback clips. When switching from live to playback content, users can immediately access the playback clip without having to wait for loading, eliminating 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 the target switch 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, when a user presses a target switching button and stops playing a target playback segment on the current interface, the system's current local time, i.e., a second timestamp when the target playback segment stops playing, can be recorded. Based on the second timestamp, the target live segment of the target channel can be retrieved and played on the current interface. The second timestamp consists of a first date and a second time point, with the second time point being later than the first time point.

[0073] For example, if a user wants to switch from a live program on a target channel to a replay of the target channel, they press the target switch button. The first timestamp of the live program stopping is 2024.09.14 12:00. If the user selects a target date of 2024.09.13, 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 of the target channel back to the live program on the target channel and presses the target switch button again. The second timestamp of the target replay segment stopping is 2024.09.14 13:00. The target live segment of 2024.09.14 13:00 is retrieved and played.

[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 live broadcast status and playback status at any time according to their needs and interests, and watch programs 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 the cache.

[0076] The step of acquiring the target live segment of the target channel according to the live timestamp includes acquiring the target live segment of the target channel from the cache according to the 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 viewing interruptions due to slow loading of live data, ensuring that users can continue to enjoy live programs, and improving their viewing experience.

[0078] In one possible implementation, a dedicated live broadcast thread is created to handle the acquisition, decoding, and playback of live program content. This ensures the real-time and smooth performance of live content, preventing other tasks from impacting live broadcast quality. Another dedicated playback thread is created to handle the decoding, caching, and playback of replayed program content. The playback thread can run independently of the live broadcast thread, ensuring that playback processing does not interfere with live broadcast processing.

[0079] In the embodiments of this application, multithreading technology is used to simultaneously process live broadcast and playback tasks, improving system response speed. Independent threads are allocated for live broadcast and playback, respectively. When users switch between playback and live broadcast, the switching process is smoother and faster because the tasks are processed independently. Because live broadcast and playback are processed in independent threads, a failure in one thread will not directly affect the operation of the other thread, improving system robustness.

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

[0081] At the data storage layer, establish an efficient storage system to store live program data and recorded playback clips. Use high-capacity hard drives or solid-state drives to ensure fast data access and storage. Categorize and index the stored data to quickly locate specific live programs or playback clips.

[0082] At the control logic layer, a dedicated control module is designed to handle user commands, such as switching live channels and selecting playback time points. A fast switching algorithm is implemented to quickly locate the target segment based on user commands and perform seamless switching. It also interacts 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, allowing users to easily switch between live broadcast and playback. Clear operation prompts are provided on the user interface to let users know how to switch between live broadcast and playback.

[0084] In summary, the present application provides a method for switching between 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 used to switch to the playback program, and the channel content of this time period can be automatically identified. It only needs to select the target date, providing 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 perform precise positioning, saving the time of manual search and fast forward and rewind, and improving the switching efficiency between live broadcast and playback.
