Embodiment 1

[0035] This embodiment discloses a system for live broadcasting programs in a theater, such as figure 2 As shown, the system includes:

[0036] Collection and compression device for collecting program code streams, compressing and encoding the program code streams, and obtaining compressed and coded program code streams;

[0037] Encapsulation sending device, used to encapsulate the video and audio in the compressed and encoded program stream obtained by the acquisition and compression device into a material exchange format MXF file, encapsulate the MXF file into a TS stream and send the TS stream to decapsulation sending Device, the MXF file includes a video MXF file and an audio MXF file;

[0038] Decapsulation sending device, used to decapsulate the received TS stream to obtain an MXF file, and send the MXF file to the playback server, the decapsulation sending device is set in the theater;

[0039] The playback server is used to de-encapsulate and decompress the received MXF file...

Embodiment 2

[0048] This embodiment discloses a method for performing live programs based on the system of the above embodiment, such as image 3 As shown, the method includes:

[0049] S1. The acquisition and compression device collects the program code stream, compresses the program code stream, and obtains the compressed and coded program code stream;

[0050] S2. The encapsulation sending device encapsulates the video and audio in the compressed and encoded program stream into a film-packed material exchange format MXF file, encapsulates the MXF file into a TS stream and sends the TS stream to the decapsulation sending device, so The MXF file includes video MXF file and audio MXF file;

[0051] S3. The decapsulation sending device decapsulates the received TS stream to obtain an MXF file, and sends the MXF file to the playing server of the theater;

[0052] S4. The playback server de-encapsulates and decompresses the received MXF file to obtain a program code stream, and sends the program code...

Abstract

The invention discloses a cinema program live telecasting system and method. The system comprises a collecting and compressing device, a packaging and sending device, an unpackaging and sending device, a playing server and a projection machine. The collecting and compressing device is used for collecting a program code stream, carrying out compressed encoding on the program code stream and obtaining a program code stream obtained after compressed encoding is carried out. The packaging and sending device is used for respectively packaging videos and audios in the program code stream obtained by the collecting and compressing device after compressed encoding is carried out to form MXF files, packaging the MXF files to form a TS and sending the TS to the unpackaging and sending device. The unpackaging and sending device is used for unpackaging the received TS to obtain the MXF files and sending the MXF files to the playing server, and is arranged in a cinema. The playing server is used for unpackaging and decompressing the received MXF files to obtain the program code stream and sending the program code stream to the projection machine, and is arranged in a cinema hall of the cinema. The projection machine is used for projecting the program code stream sent by the playing server.

Description

Technical field [0001] The invention relates to the field of multimedia technology, in particular to a system and method for live broadcasting programs in theaters. Background technique [0002] Existing movie playback systems in theaters, such as figure 1 As shown, the system is based on a non-real-time file-based projection system, which receives the film through the satellite receiving subsystem, and imports the film from the hard disk or the network to the playback server, and the playback server decapsulates and decompresses it to obtain the code Stream, the code stream transmission arrives at the movie projector to play. [0003] In recent years, theaters have begun to try to carry out live broadcast services of 2D or 3D programs such as ball games and concerts, but they adopt a stream-based TV live broadcast program, that is, the program data of live TV is compressed by the Motion Picture Experts Group (MPEG) and encapsulated as Transport Stream (TS) stream, TS stream is tr...
