An embodiment of the present application provides a display device, including:

at least one tuner for tuning a digital broadcast signal;

a communicator configured to perform data communication with a server;

a controller configured to:

when the program signal is a digital broadcast television signal, demodulating the digital broadcast television signal to obtain a broadcast television video file, and playing the broadcast television video file on the user interface; illustratively, when a user selects a certain program control to input an instruction through the control device 100, if the program signal connected to the current display device is a digital broadcast television signal, the controller responds to the instruction to acquire the broadcast television signal, demodulates the broadcast television signal to obtain a broadcast television video file, and plays the broadcast television video file on the user interface.

When the program signal is a live broadcast network signal, a live broadcast index file request is generated according to the live broadcast network signal, the live broadcast index file request comprises a live broadcast index file, the live broadcast index file request is uploaded to the server, so that the server returns a live broadcast video file searched according to the live broadcast index file, and the live broadcast video file is played on the user interface. Illustratively, as shown in FIG. 6, the display device loads a sub-channel list of the "channel" application on the user interface. Illustratively, the playlist of the "channel" application includes: short video, documentary, music, fitness, shopping, education, etc. When a user selects a program control to input an instruction through the control device 100, for example, selects a program control of 173 buffalo music on the body-building sub-channel, because the program is a live program, in response to the selection instruction, a program signal corresponding to the program control is acquired, where the program signal is a live network signal. And generating a live broadcast index file request of the tremble medicated dance according to the live broadcast network signal, wherein the live broadcast index file request comprises a live broadcast index file of the tremble medicated dance, uploading the live broadcast index file to a server, searching a corresponding tremble medicated dance live broadcast video file according to the live broadcast index file by the server, returning the searched tremble medicated dance live broadcast video file, and simultaneously playing the tremble medicated dance video file on a user interface of display equipment.

The method comprises the steps that after a live network signal is obtained, a controller generates a live index file request according to the live network signal, the live index file request comprises a live index file, the live index file request is uploaded to a server, so that the server returns a live video file searched according to the live index file, and the live video file is played on a user interface. Specifically, the server returns to search a corresponding live video file according to the live index file of the tremble medicated dance, and plays the tremble medicated dance video on the user interface.

Video content data recorded in real time are acquired by a server component, and are subjected to media coding to obtain video content data in an MPEG (Moving Picture Experts Group) -4 format, and then are packaged into a transport stream of MPEG-2 by hardware. The transport stream passes through a data stream slicer, and the video content data is stored as one or more series of ts-formatted live video files after being divided into small segments. When the video content data is sliced, a live index file is also created, and an index file list of M3U8 is formed. The index file in the list is associated with a URL (Uniform Resource Locator), and the location of the available live video file can be specified by the index file and the URL. For example, after the controller acquires the live broadcast index file of the jolting god dance, the live broadcast video file of the jolting god dance can be acquired according to the live broadcast index file of the jolting god dance, and the live broadcast video file of the jolting god dance is played on the user interface of the display device. Because the video is recorded in real time, the live broadcast index file needs to be updated continuously so as to obtain a new live broadcast video file continuously and realize the purpose of live broadcast.

Because the live broadcast mode based on the HLS protocol is to divide live broadcast content data into small video fragments of 5-10 seconds, then manage the video fragments by using an m3u8 index table, and videos downloaded by display equipment are all complete data of 5-10 seconds, the fluency of the videos is better, but when the live broadcast data is constructed, a server needs to encode/transcode original videos or audios and then sends the original videos or audios to the display equipment for playing, so that a larger delay (generally, the delay is 10-30 seconds), and the high delay is unacceptable for live broadcast needing real-time interactive experience. According to the method and the device, live broadcast data of the HLS are constructed by utilizing the on-demand data of the HLS, and the video content data can be sent to the display equipment without encoding/transcoding the original video or audio, so that the video content data can be played by the display equipment, and delay is shortened.
