Abstract
An embodiment of the invention relates to the digital television field, in particular to an EPG (electronic program guide) distribution method, an EPG device and a terminal device. The EPG distribution method includes that a plurality of digital television operators acquire media data; the EPG device receives program information sent by television stations and generates deep EPG information; the deep EPG information is distributed to the terminal device according to watching requests sent by users; user information and designated program information selected according to the deep EPG information are received and a digital television operator is determined according to the user information, corresponding play messages are matched in the entire play messages of the digital television operator, and the play messages are provided to the terminal device; and the terminal device acquires corresponding media data according to the play messages of the digital television operator. By the method of sending the program information independent of the media data separately, digital television operators have no need to perform EPG editing and reviewing repeatedly, so that cost is reduced and complexity degree of an EPG system is simplified.
Description
Technical field
The present invention relates to digital TV field, be specifically related to distribution method, EPG device and the terminal equipment of a kind of EPG.
Background technology
Cultural industry development and the integration of three networks are just promoting China Digital TV and are moving towards fast-developing track.According to Glan research statistics, China cable digital TV user has broken through 100,000,000, and the cabled digital degree surpasses 60 percent, and the IPTV of broadcasting and TV and telecommunications cooperative development and internet television are also constantly popularized simultaneously, and market scale constantly enlarges.Can predict, under industry fusion and technology driving, the Digital Television related service will increase substantially the coming years, and Digital Television has entered Rapid development stage.
Digital Television is different fully on the mode that program is selected with simulated television.The corresponding program of each channel of simulated television, as long as be transferred to corresponding frequency, the user just can see image.And in Digital Television, a plurality of programs are multiplexed in the code stream, each program only occupies the part bag in the code stream, the channel of such physics can only provide the transport stream that comprises a plurality of programs, watch certain program wherein, also must from code stream, extract the transmission package of program correspondence, and then decode.Need to provide some service information needed, for example programme distant information etc. selects program to be very important to help the user for this reason.
Electronic program guides (EPG, Electronic Program Guide) can provide abundant programme distant information, and have conveniently, content retrieval engine flexibly, can browse and inquire about programme information easily by its user, simultaneously can also see more programme information by electronic program guides, as program brief introduction, actor information, program segment etc.By EPG, the user can navigate to the program of oneself liking fast, also is convenient to the service that the user obtains richer personalization simultaneously.We can say that EPG is the door that spectators enter the digital and electronic program, realized the substantial interaction between digital content supplier and the consumer.
In Digital Television, all sounds, vision signal and data message, must be packed according to Moving Picture Experts Group-2 before entering legacy system through after encoding, and form transport stream (TS, the Transport Stream) bag of regular length.For the identical TS bag of these length, if there is not guidance information, terminal can't find needed code stream.In Moving Picture Experts Group-2, defined program specific information PSI (Program Specification Information) for this reason specially, its role is to setting automatically and guiding terminal and decode.PSI information is made up of following four kinds of tables: (1) Program Association Table PAT; (2) Program Map Table PMT; (3) network information table NIT; (4) conditional access table CAT.In actual applications, when decoder terminal will be decoded to a certain road special code stream, at first to find pat table, find the identity code transmission package (PID, Packet IDdentifier) of the pmt table of required program and this program correspondence according to pat table.May comprise a plurality of digital code streams in the pmt table, each code stream has a unique PID corresponding with it.If decoding is video code flow, then in pmt table, find the video pid value, from code stream, filter out pid value again and with the TS of its coupling bag and deliver to Video Decoder.The PSI of MPEG-2 provides the information of related-program composition and correlation, thereby makes terminal to resolve multiple path transmission flow.
But, the PSI information of MPEG-2 can not provide the program information such as additional information of time started, duration and program of title, the program of program, for this reason in the digital video broadcasting (DVB, Digital Video Broadcasting) expanded definition business information SI.PSI information substantially all is relevant with existing stream (AS, Actual Stream), and SI then can comprise not some business and the event information in existing stream, thereby allows the user more to select and understand more other business information.Different with four kinds of tables of PSI definition, defined 9 kinds of tables among the SI, the most important table that wherein constitutes basic EPG information is network information table NIT, SDT Service Description Table SDT and Event Information Table EIT.The information that SI table transmits all is that the form by descriptor (descriptor) provides.
EPG information is divided into two kinds of basic EPG information and expansion EPG information.Basic EPG information is to be described with the SI information table, that represents with text formatting describes the relevant network information, program group information, business description information and event information with program, represent and transmit by NIT, BAT bouquet association table BAT, SDT, EIT and the EMT that stipulates among the GY/T231-2081, these tables are divided into one or several sections (SECTION), each fragmented packets contains part or all about the information of table, is inserted into then in the TS flow transmission bag.Expansion EPG information is the expansion on basic EPG information basis, and it describes more programme information, as program brief introduction, actor information etc.
Realize EPG at present, need utilize SI to show to realize, in this method, transmitting terminal transmitting and receiving terminal equipment is realized the SI table that EPG is required, and the SI that the receiving terminal receiving end/sending end sends table, by information extraction and information reorganization, the EPG that organizational composition is complete, and be shown to the user.But there is following shortcoming in aforesaid way:
1) the EPG dynamic content information derives from TV station, each digital-TV operator need be obtained dynamic EPG content information from each TV station or third party, each operation commercial city wants used device, input special messenger to go to collect the dynamic EPG information of editing and updating every day like this, and equipment drops into and repeats, content update work repeats;
2) EPG is the entrance of digital television terminal user, and EPG derives from single operator, has therefore caused the binding of terminal and operator;
3) the EPG content information updating of each operator is asynchronous, inconsistent, causes user's puzzlement and complaint.
Summary of the invention
The distribution method of a kind of EPG that the embodiment of the invention provides, EPG device and terminal equipment, be used for solving each operation commercial city of prior art and want used device, input special messenger to go to collect editing and updating dynamic depth EPG information every day, equipment drops into and repeats, content update work repeats and asynchronous, the inconsistent problem of EPG content information updating of each operator.
