Description
Technical field
The present invention relates to digital TV field, relate in particular to a kind of method and device that is used for digital TV software upgrade.
Background technology
So-called Digital Television is meant the television system or the television equipment that use digital television signal in the processing, transmission, emission, receiving course of TV signal.The general implementation procedure of digital television business is: with the analog signals such as video, audio frequency of picked-up, after digital compression, coding and modulation, form digital signal, via satellite, mode such as terrestrial wireless broadcast or wire cable transmits, receive by the digital TV front-end system, and restore analog signals such as video, audio frequency by digital demodulation and decoding processing and display the play.Because the digital television business overall process all adopts digital technology to handle, so the loss of signal is little, reception is good.
Digital Television is based on that the digital television software preserved in the flash memory on the mainboard (Flash) moves.This digital television software belongs to the default configuration when dispatching from the factory.When the coded system that program is transmitted when digital-TV operator changes, or the Digital Television manufacturer is when improving or releasing new function to software, and the digital television software of original version just can not adaption demand, the renewal of need upgrading.In addition, along with the increase of Digital Television coverage rate, other application of Digital Television also progressively are enriched, and comprise the stock inquiry, real-time game, and new function such as video request program is arisen at the historic moment.Different users causes them can not be satisfied with single digital television software to the preference of different software function.Therefore, Digital Television manufacturer or operator need provide variation and alternative digital television software regularly to upgrade to the user.
In order to solve the renewal upgrade problem of digital television software, the following two kinds of ways of the many at present employings of Digital Television manufacturer or operator:
First, embedded communication interface on the mainboard with Digital Television, serial ports for example, network interface, USB (Universal Serial Bus, USB) interface, PCMCIA (Personal ComputerMemory Card International Association, international personal computer memory card association) interface links to each other with a computer, and digital television software new on the computer is written in the flash memory on the mainboard by communication interface.The defective of this mode is to need the technical support personnel that each user is made house calls, and has increased the workload and the cost of technical support.
The second, utilize the NIT (Network Information Table, network information table) among the MPEG-2 (Moving Picture Experts Group-2, moving picture expert group 2) to transmit.The program source of Digital Television is to encode according to the standard of MPEG-2, and the packet that the various SI of program source content and program source (ServiceInformation, information on services) information has been compiled to the MPEG-2 of 188 bytes transmits.Digital Television manufacturer offers digital-TV operator with new software version, operator splits the content of new digital television software in many packets, the index information of these packets put in the NIT table among the SI go, send the Digital Television of receiving terminal then to.Receiving terminal at first finds the index of all packets from NIT table, and with they formation upgrade softwares that combines, and is written in the flash memory and goes.It is enforceable that the shortcoming of this method is to download, in case digital-TV operator is sent the demand of software upgrading, all receiving terminals must be downloaded; And the version of the upgrade software of downloading is single, and the NIT table is included in MPEG 13818 agreements among the SI, promptly only allow the software of a version of transmission only with the index that a update software position is provided, so user's selection also is single.
In summary, the upgrade technique of existing digital television software obviously exists inconvenience and defective, so be necessary to be improved on reality is used.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be understood that specific embodiment described herein is only in order to explaining the present invention, and be not used in qualification the present invention.
Basic thought of the present invention is: the digital television service end sends number of digital TV upgrade software by DSM-CC to digital television receiving terminal, and digital television receiving terminal receives the part or all of digital TV upgrading software (ROMPaq bag) of described number of digital TV upgrade software (ROMPaq bag) and carries out upgrading processing.
The present invention utilizes digital storage media order and control (Digital Storage Media Commandand Control, DSM-CC) data carousel/object carousel (Data Carousel, DC/ObjectCarousel, OC) technical transmission, a plurality of digital TV upgrading softwares of reception.
DSM-CC is an ISO/IEC (International Standards Organization/InternationalElectrotechnical Commission, International Standards Organization/International Electrotechnical Commission) protocol stack of standard 13818-6, in order to be provided at digital storage media (Digital Storage Media, DSM) go up required basic controlling function and the operation of management mpeg format code stream, broadband multimedia services is provided, it is positioned on the operating system layer, under the application layer, be independent of the digital storage media of being managed, transport network layer, the associated procotol and the operating system at place.
At DVB (Digital Video Broadcasting, digital video broadcasting) in the protocol stack, DSM-CC be from bottom to top MPEG2 form type code fluid layer, section (Section) layer, DSM-CC DC/OC layer, Service Description (Service Specific) layer, use (Application) layer etc.
In order to realize the digital broadcasting of DSM-CC in the transmission that is implemented in common mpeg stream, in the Section of the ISO/IEC13818-1 definition except comprising the tabular definition of SI, also reserved definition for DSM-CC, therefore DSM-CC can be used for great amount of data transmission, thereby can transmit a plurality of softwares and provide explanation.And in DSM-CC, data are to transmit by the form that is divided into module.Wherein, each module comprises some files, and one of these module are right after a mode cyclical transmission by broadcasting.If receiving equipment will receive a file, need to wait for to receive the module that comprises this document, obtain file by this module.And the data carousel of DSM-CC is a kind of application of DSM-CC user-network data download protocol (DSM-CC U-N Download) under broadcasting (Broadcast) environment.
DC/OC can support periodically to transmit the various application of data module.The DC agreement of the DSM-CC that uses in the DVB digital video broadcast system is mainly used to transmit the transfer of data except the basic announcement video traffic.Data carousel DC periodically sends data module by radio network.The data that send in DC are organized into module, separate data on the presentation logic.Module further is divided into piece, and all block sizes are the same.The module of DC is described by control messages.According to control messages, the user can choose the module (for example file) that needs from DC.Aspect broadcasting, module can be upgraded at any time, adds DC or deletes from DC.Object carousel OC is based upon on the basis of DC, and in OC, module upgrade is an object.The support of OC standard is periodically broadcasted the business of DSM-CC user to user object by radio network.The data broadcasting normalized definition of DVB object transfer approach on radio network, object carousel system implementation method is by DVB interactive service protocol definition.
