Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a coupling diagram of the set-top box of the present invention.
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention, taken in conjunction with the accompanying drawings and the detailed description, is given in a non-limiting manner.
As shown in fig. 1, the set-top box of the present embodiment includes: the system comprises a control module 1, and a bidirectional information request receiving module 2, a unidirectional information receiving module 3, a cache module 4 and an interface module 6 which are coupled (with electric signal interaction) at the periphery of the control module 1.
In this embodiment, the bidirectional information request receiving module 2 is a network card, is coupled to a broadcasting and television cable (including a coaxial cable or an optical fiber) through an existing network cable interface module of the set-top box, and accesses to the broadcasting and television network through the broadcasting and television cable to perform bidirectional unicast communication with the broadcasting and television server, that is, requests service from the broadcasting and television server and obtains received reply information, and is mainly used for performing 3A authentication on the set-top box. Specifically, the set-top box is provided with a bidirectional broadcast server address when leaving a factory, the set-top box firstly acquires the address after being started, then sends a request to the address for communication, and acquires early warning information at regular time. If the address of the bidirectional broadcasting and TV server is changed, the information is sent to be modified into a new address at 3A.
In this embodiment, the unidirectional information receiving module 3 is a high-frequency tuner, is coupled to a broadcasting and television cable (including a coaxial cable or an optical fiber) through an existing network cable interface module of the set-top box (which may be in the same port as the network interface module of the bidirectional information request receiving module 2), and is accessed to the broadcasting and television network through the broadcasting and television cable, and performs unidirectional multicast communication with the broadcasting and television server. After the bidirectional information request receiving module 2 performs 3A authentication, the set top box simultaneously locks the frequency, the broadcasting and television server broadcasts the latest meteorological disaster emergency early warning information through the broadcasting and television cable in a unidirectional network, the meteorological disaster emergency early warning information is a TS (transport stream) file, and the unidirectional information receiving module 3 acquires the meteorological disaster emergency early warning information in a unidirectional mode.
In this embodiment, the cache module 4 adopts a NAND-FLASH memory, which is coupled to the unidirectional information receiving module 3. The cache module 4 stores the early warning information in the set-top box, and identifies the information which is early warning and ends early warning, so that people are prevented from being disturbed due to repeated early warning.
In this embodiment, the control module 1 is a set-top box main control chip, and the main control chip may adopt the morning star MSD7C51J or the haisi Hi3798mv200, and is configured to perform data comparison on the latest received early warning information and the early warning information cached in the cache module 4, and send an electrical trigger signal to the audible and visual alarm through the interface module 5. In this embodiment, the interface module is a USB interface module, and is disposed on the set-top box and configured to be coupled to the external audible and visual alarm 6, and after the audible and visual alarm is successfully connected to the USB interface module of the set-top box, the set-top box displays that the audible and visual alarm is successfully connected to the interface.
The early warning of the audible and visual alarm is to control the light ray flicker and the sound interval frequency of the audible and visual alarm. Besides sound and light alarm, the early warning mode can also be provided with game character broadcast, picture broadcast, voice broadcast, video broadcast and digital tube flash alarm, wherein the voice and video broadcast plays the voice or video data under the appointed pid and frequency point, and can also directly jump to the appointed channel.
The working process is as follows: the set-top box is started, and the bidirectional information request receiving module carries out 3A authentication; after the authentication is passed, the set top box locks frequency, and the unidirectional information receiving module acquires early warning information in a unidirectional mode; if the early warning information is acquired, the early warning information is compared with the early warning information cached in the caching module, the outdated or early warning information which is already early warned is discarded, and the early warning information to be early warned is cached; triggering the early warning information, and controlling an audible and visual alarm to perform audible and visual alarm by a control module; the early warning information is naturally ended or the user forcibly quits.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
