Abstract
The invention discloses a method for realizing DVB service based on IP on a set top box. The set top box used is a cable, satellite or terrestrial receiver set top box, which can access the internet. A network server is built at the front end of the DVB, the DVB service information and the corresponding version number are organized into a service file in a jason format, the service file is broadcast to a network, a DVB terminal set top box receives the service file and analyzes the service file to obtain new DVB service information and the corresponding version number, if the version number is larger than the version number of the stored DVB service information, the original DVB service information is deleted, and the new DVB service information and the corresponding version number are stored to the set top box; otherwise, the original DVB service information is not processed. And the DVB terminal set top box receives the audio and video data sent by the DVB front end in a traditional mode by utilizing the stored DVB service information, decodes the audio and video data and plays the audio and video data. The invention simplifies the operation steps when watching programs and reduces the waiting time.
Description
Technical Field
The invention belongs to the technical field of digital television set top boxes, and relates to a method for realizing DVB service based on IP on a set top box.
Background
The Set Top Box (STB) includes hardware and software, and is a device for processing an external input signal source and outputting the processed signal source to a television for display. External signals are transmitted in different ways (cable, satellite, terrestrial), the external signals come from a broadcast operator, and the set-top box can access the internet through a network lan interface.
The digital video broadcasting organization (Digital Video Broadcasting Project) is an industry organization consisting of more than 300 members, which is initiated by a joint expert group consisting of the European telecommunication standardization organization, the European electronic standardization organization and the European broadcasting Union. DVB (Digital Video Broadcast, digital video broadcasting) is a series of internationally recognized digital television public standards maintained by the digital video broadcasting organization.
DVB digital broadcast transmission systems utilize all general purpose television broadcast transmission media including satellite, cable, terrestrial. The DVB standards to which they respectively correspond are: DVB-S, DVB-C, DVB-T. The system adopts audio, video and data formats compressed by MPEG-2 as resources; using public MPEG-2 Transport (TS); the transmission system is divided into two parts, namely Source Coding (Source Coding) and Channel Coding (Channel Coding). Source coding first multiplexes MPEG-2 encoded audio and video, and then multiplexes multiple digital television program streams for transmission. And corresponding demultiplexing and decoding are carried out at the receiving end. The DVB front end refers to a broadcast operator and the DVB terminal refers to a set top box end of a user.
The DVB service information refers to necessary information for program broadcasting and detailed information for program introduction, and the DVB service information is received and decoded by the set top box through the above network, and then is revealed to the user to watch DVB service information including (program specific information) PSI and (program service information) SI, which is information for introducing and managing programs, and when the user at the set top box end watches programs, the information can be seen, including names of program channels, currently broadcasted program information, information of the next program, and the like.
When watching a set-top box program, the requirement is that DVB service information data and audio and video data of the program are received, and the two data are produced and transmitted by the DVB front end. The DVB front end typically packages DVB service information data and program audio-video data using specific tools and then transmits the packaged data in different ways (satellite, cable, terrestrial).
Disclosure of Invention
The invention aims to provide a method for realizing DVB service based on IP on a set top box.
In the method of the invention, the DVB terminal set top box is a cable, satellite or ground receiver set top box and can access the Internet. The specific DVB service implementation method comprises the following steps:
the DVB front end builds a network server with a specific IP address, and the DVB terminal set top box is accessed to a network and can receive network data sent by the DVB front end;
the DVB front end transmits other data except DVB service information in TS stream of MPEG-2 standard to DVB terminal set-top box through cable, satellite or ground;
the DVB front end organizes DVB service information in the MPEG-2 standard and data of a corresponding version number into a service file service. Jason in a jason format, and broadcasts the service file service. Jason to a network through a network server; the DVB front end linearly increases the corresponding version number when sending a new service file service. The DVB service information is necessary information for playing programs and detailed information for introducing the programs;
the DVB terminal set top box sends a request to a network server with a specific IP address at intervals of set time to acquire a service file service. Jack;
the DVB terminal set top box analyzes the acquired service file service. Jason to obtain new DVB service information and a corresponding version number; comparing the analyzed DVB service information version number with the DVB service information version number stored in the DVB terminal set-top box, deleting the DVB service information version number stored in the set-top box and the corresponding DVB service information if the DVB service information version number is larger than the stored DVB service information version number, and storing the analyzed DVB service information and the corresponding version number in the set-top box; if the DVB service information version number is smaller than or equal to the stored DVB service information version number, the stored DVB service information in the set top box is not processed;
and the DVB terminal set top box receives the audio and video data sent by the DVB front end through the cable, satellite or ground by utilizing the stored DVB service information, decodes the audio and video data and plays the audio and video data.
The method of the invention transmits DVB service information and corresponding version number in TS stream of MPEG-2 standard in network mode, other data is transmitted in traditional wired, satellite or ground mode. By adopting the method of the invention, the DVB terminal set top box can directly broadcast the audio and video programs only by receiving DVB service information in a network mode when being started, and does not need to search DVB service information in TS stream in a traditional mode to broadcast the audio and video programs, thereby simplifying the operation steps when watching the programs and reducing the waiting time.
