Description

Display device and content source list screening method Technical Field The application relates to the technical field of display equipment, in particular to display equipment and a content source list screening method. Background In the context of digital video broadcasting and Internet convergence, the digital video broadcasting-Internet (DVB-I) standard aims to build a unified framework to integrate conventional broadcast signals such as digital video Terrestrial broadcasting (Digital Video Broadcasting-terrestrials, DVB-T), digital video Satellite broadcasting (Digital Video Broadcasting-Satellite, DVB-S). Also for example, dynamic adaptive streaming over HTTP (DYNAMIC ADAPTIVE STREAMING over HTTP, DASH), HTTP real-time streaming (HTTP LIVE STREAMING, HLS). In this framework, the same television program is often available from multiple content sources, each of which varies in availability, time of service, priority, and real-time status. The method and the device bring core challenges to terminal receiving, namely, how to intelligently and stably select and switch content sources under different network conditions so as to ensure continuous and high-quality viewing experience, and become key to influencing technical landing and user perception. To address this problem, the industry has proposed several solutions. The digital video broadcast-internet standard provides a basis for content source identification through a unified service discovery and metadata mechanism. Some embodiments employ predefined static rules such as preferentially selecting broadcast signals or switching to IP stream backup when signal quality drops. There are also methods to set a switching threshold based on simple signal indicators (such as bit error rate, signal strength) measured at the receiving end, so as to achieve basic complementation between different transmission paths. However, existing schemes mostly rely on passive responses to current or historical channel conditions, and the switching action is often delayed from the degradation of the network state, which can easily lead to interruption of playback. The switching logic based on the fixed rule or the simple threshold is difficult to adapt to complex and changeable actual network environments, and further, high-quality continuous playing experience is difficult to ensure. Disclosure of Invention The application provides display equipment and a content source list screening method, which can effectively solve the problem that high-quality continuous playing experience is difficult to ensure due to single screening rule of multiple content sources. In a first aspect, an embodiment of the present application provides a display apparatus, including: a display; a controller configured to: Under the condition that a first channel searching event is triggered, obtaining content source data, wherein the content source data comprises mapping relation of channels and a plurality of content sources, priorities of the plurality of content sources, service time of the plurality of content sources and state marks of the plurality of content sources; determining a first candidate content source according to the priorities of the plurality of content sources; Acquiring the system time of the display device and the first service time of the first candidate content source; If the system time is within the range of the first service time, acquiring a first state mark of the first candidate content source; Determining a content source list based on the first candidate content source under the condition that the first state mark represents that the first candidate content source is effective, wherein the content source list comprises the mapping relation between the channel and the first candidate content source corresponding to the channel; and playing the media content of the channel based on the first candidate content source in response to a selection instruction for selecting the channel. In this way, by acquiring and processing the data including the priority of the content source, the service time and the status flag, the optimal content source corresponding to each channel can be screened in advance in the background, and a content source list can be formed. When the user selects the channel, the system automatically checks whether the current time is within the active service period of the optimal content source and checks whether it is marked as active. And playing the program directly by using the content source under the condition that the content source and the content source meet each other. By increasing the service time and the detection dimension of the state mark, the quality of the content source is improved, and the playing stability of the media asset is ensured. In some possible implementations, after the controller performs the obtaining the system time of the display device and the service time of the first candidate content source, the controller is further con
