Description

Technical Field

[0001] The present invention relates to the technical field of satellite live television, and in particular to a satellite live television receiver system capable of accessing a network. Background Art

[0002] Traditional TV viewing methods mainly include cable TV, Internet TV and satellite live TV. Compared with other TV, the biggest advantage of satellite live TV is that it can broadcast hundreds of TV programs to an unlimited number of home users with limited satellite resources.

[0003] Currently, satellite live TV receivers lack viewing flexibility and can only simply realize a live TV program viewing function. They usually provide limited channel selection. Users may not be able to get all the channels they want to watch, or they need to pay extra to subscribe to get more channels. Compared with cable TV, the additional subscription fee is expensive. In addition, the signal reception of satellite live TV receivers is easily affected by weather conditions. Severe weather, such as storms, heavy snow or strong winds, may cause signal interruption or quality degradation, which directly affects the user's viewing experience and usage experience. Summary of the invention

[0004] The present invention provides a satellite live television receiver system that can access a network, in order to solve the technical problems existing in the background technology.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The main control module is used to process, demodulate and decode the received signals, realize the reception and analysis of satellite signals and ground signals, and is connected with other functional modules;

[0008] The demodulation circuit module can simultaneously receive ABS-S satellite signals and DTMB digital TV signals, and demodulate the satellite live signal and terrestrial digital TV signal into TS streams through the satellite live signal demodulation system and the terrestrial digital TV signal demodulation system respectively;

[0009] The power module provides power support to each unit of the receiver and feeds the satellite antenna;

[0010] The 4G LTE module is connected to an external antenna for receiving and sending wireless signals. The 4G LTE module connects to the SIM card through the SIM card slot, connects to the mobile operator's network through its built-in wireless communication function, authenticates the operator's network, and obtains necessary service configuration and network access rights. The 4G LTE module is connected to the 4G network, and the receiver can transmit data through the 4G LTE module.

[0011] The system integrates a 4G LTE module and a SIM card slot. When users watch live content through a satellite receiver, the receiver receives satellite signals through a satellite antenna and decodes them for display on a connected display device. If the satellite signal is interfered with or interrupted, the system can automatically (or manually by the user) switch to the network connection provided by the 4G LTE module to continue receiving the live stream through the Internet. The 4G LTE module communicates with the nearest 4G network base station through a built-in or external antenna, and establishes a data connection after verifying the user's identity through a SIM card. The satellite receiver then receives live data packets from the Internet through the 4G LTE module, decodes them, displays them on the screen, or shares them over the network.

[0012] In some embodiments, the main control module is composed of a decoding chip and storage chips DDR and FLASH.

[0013] In some embodiments, the demodulation circuit module is composed of a TUNER and a DEMOD, and the decoding chip descrambles and decodes the TS stream, and the output video stream and audio stream are displayed through the display module.

[0014] In some embodiments, the DCAS module implements secure processing of live broadcast signals through an encryptor, a decryptor, a control system, and a smart card.

[0015] In some embodiments, the Beidou positioning module establishes communication with the Beidou satellite system, receives signals from multiple satellites, and calculates the position of the receiver; it is used to guide the positioning of the antenna and docking satellite signals.

[0016] In some embodiments, the emergency broadcast module establishes a stable communication connection with the external broadcast system to ensure that users can reliably receive and play information in an emergency.

[0017] In some embodiments, data communication between the 4G LTE module and the decoding chip is performed through a USB / UART interface.

[0018] In some embodiments, the software application control module is used to complete the porting of the device driver of the built-in 4G LTE module, modify the USB-to-serial port driver code of the Linux native kernel, add the module's vendor ID and product ID to the device list, so that the 4G LTE module can be recognized by the host computer after power-on, and add the RNDIS driver in the kernel.

[0019] The beneficial effects that may be brought about by a satellite live TV receiver system that can access the network disclosed in this application include but are not limited to:

[0020] 1. Realize the online live broadcast function. Users can watch online live programs, sports events, news, etc., and are no longer limited to the channels and programs of traditional satellite live broadcast.

[0021] 2. Realize video on demand. Users can choose their favorite TV series, movies, variety shows, etc. to watch on demand anytime and anywhere.

[0030] The main control module is composed of a decoding chip and storage chips DDR and FLASH. It receives and analyzes satellite signals and ground signals by processing, demodulating and decoding the received signals. At the same time, it controls and manages the various functional modules of the receiver to make the receiver work normally.

[0031] The demodulation circuit module consists of TUNER and DEMOD, which can receive ABS-S satellite signals and DTMB digital TV signals at the same time, and demodulate the satellite live signal and terrestrial digital TV signals into TS streams through the satellite live signal demodulation system and the terrestrial digital TV signal demodulation system.

This position information is passed to the receiver's control system to guide the positioning of the antenna and docking satellite signals.

[0034] The emergency broadcast module recommends a stable communication connection with the external broadcast system to ensure that users can reliably receive and play information in an emergency.

[0035] The data communication between the 4G LTE module and the CPU is carried out through the USB / UART interface, and at least one antenna or an antenna interface is required to connect an external antenna to receive and send wireless signals. The module connects to the SIM card through the SIM card slot, and then connects to the mobile operator's network through its built-in wireless communication function, authenticates the operator's network, and obtains the necessary service configuration and network access rights. Once the module is connected to the 4G network, the receiver can transmit data through the module. Users can access Internet-related content through the network to realize the live broadcast function, no longer limited to the channels and programs of traditional satellite live broadcasts; realize video on demand, pause, and replay functions; realize application expansion functions, users can download and install various applications; realize remote control, users can remotely control the satellite live TV receiver through mobile phones or computers and other devices to switch channels, record programs, adjust settings, and improve user convenience.
