Embodiment 1

[0028] A method for realizing multimedia program distribution is composed of the following processes:

[0029] 1. Program search process of satellite live TV receiving equipment

[0030] 1) Identify the tuner and set the number of device tuners, and save it to the configuration management system;

[0031] 2) Search programs on a tuner and save the results to the configuration management system;

[0032] 3) Repeat step 2) until all Tuners are traversed;

[0033] 4) The configuration management system configures broadcast addresses of all programs;

[0034] 2. Live TV receiving equipment distributes live program receiving process

[0035] 1) The configuration management system tunes Tuner1 to the set frequency point;

[0036] 2) The configuration management system sets the information of program 1;

[0037] 3) The distribution system receives the data of program 1 and saves it in the local memory;

[0038] 4) Repeat steps 2) and 3) until all programs of the set frequency p...

Embodiment 2

[0061] combined with figure 1 Shown, a kind of satellite TV live broadcast system that realizes the distribution of multimedia programs includes a satellite live TV receiving device and a playback terminal, and the satellite direct TV receiving device includes multiple Tuners, a descrambling system, a configuration management system, a distribution system and a first network module, where:

[0062] Multiple tuners for receiving satellite live programs;

[0063] The descrambling system is used to demodulate the satellite live programs received by the Tuner;

[0064] Encryption system, used to encrypt the demodulated program information;

[0065]The configuration management system is used to save the Tuner quantity and the encrypted program, and configure the broadcast address of the program; it is also used to tune the Tuner to the set frequency point, and set the program data corresponding to the Tuner;

[0066] The distribution system is used to receive the program data co...

Abstract

The invention discloses a method for realizing multimedia program distribution, which comprises the following steps that: arranging a plurality of Tuners in satellite live broadcast television receiving equipment, and broadcast addresses are configured for searched programs after the searched programs are demodulated; tuning each Tuner to a corresponding frequency point, setting program data, andpackaging the data; performing data broadcasting and sending a program playing list according to the broadcasting address; and acquiring the program playing list and the program playing address, receiving the program data and decoding and playing the program data by a playing terminal. The invention further discloses a system which comprises the satellite live broadcast television receiving deviceand a playing terminal, and the satellite live broadcast television receiving device comprises a plurality of Tuners, a descrambling system, a configuration management system, a distribution system and a first network module. According to the method and the system, multiple Tuners are adopted to realize the reception of multiple program signals, and live programs are distributed through the network, so that the function of simultaneously and freely watching different live programs by multiple playing terminals connected to the network is realized.

Description

technical field [0001] The invention relates to the technical field of satellite TV live broadcast, in particular to a method for realizing multimedia program distribution and a satellite TV live broadcast system. Background technique [0002] Direct broadcast satellite is a dedicated communication satellite that directly relays TV or audio broadcasting programs to the public, and is mainly used for live TV broadcasting. Live TV receiving equipment can realize watching TV programs by receiving live satellite signals. Since satellite signals are less affected by environmental factors, live TV coverage can be achieved for areas where ground signals and cable signals are difficult to cover, such as remote mountainous areas, oceans, and polar regions. The current live TV receiving equipment mostly uses one receiving antenna, and broadcasts live programs through the video output interface of the equipment, but limited by the limitation of only one video output interface, only on...
