Description of drawings

Fig. 1 is the network structure of one embodiment of the invention.

Fig. 2 is the system framework figure of one embodiment of the invention.

Embodiment

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 shows the network configuration of one embodiment of the invention.As shown in Figure 1, in the network of front end, connect into unified loader system 100 by the network switch 104 by client 101, SSU (system software upgrading, System Software Upgrade) data server 102, SSU information database 103.Multiplexer 200 connects with SSU data server 102, and EPG (Electronic Program Guide) system 301 is connected with unification loader system 100 by the network switch 104 with OSS/SMS (Operational Support System/Subscriber Management System) system 302.

Fig. 2 shows the system framework of one embodiment of the invention.As shown in Figure 2, unify loader system 100 and can be divided into Configuration Manager 111, playing and scheduling module 112, SSU data server 102 and SSU information database 103.Wherein SSU data server 102 is deployed on the server that uses (SuSE) Linux OS, and all the other modules all are deployed on the client computer that uses Windows operating system.

The implementation procedure of each module in the unified loader system 100 is described below in conjunction with an example.In this example, certain set-top box production firm provides a loader file and corresponding loader description document.This loader description document thes contents are as follows: production firm's title: ABC, hardware version: 0082, software version: 0X44, download formats: privately owned form, file format: the TS file, and this loader file leaves the inferior information of D packing catalogue on the SSU data server 102 in.If upgrading, it is identical and a loader file that software version is higher is used for online upgrading generally to need to generate hardware version, thereby supposes that here its software version to be upgraded is 0X43.

Manufacturer after loader file that operator is provided for upgrading and corresponding loader description document, Configuration Manager 111 according to the loader description document with corresponding loader file transfer in the specified path of SSU data server 102.Simultaneously, the loader record of Configuration Manager 111 newly-increased correspondence in SSU information database 103, the form of this record is followed successively by: manufacturer's information, hardware version, software version, loader file format, the memory location of loader file on SSU server 102.Here, the record that increases newly is " ABC, 0082,0X44, TS file, D: ".The all corresponding different loader record of each different loader file, and a loader database of record formed in all loader record.

Certainly, Configuration Manager 111 can be not yet by extracting the loader description document information but directly manually add the loader record according to the relevant information that manufacturer provides.Whether Configuration Manager 111 also can detect the loader description document wrong, can judge whether the loader file can be used for upgrading broadcasting, if the loader file has been the TS file, can judge also whether its form satisfies the requirement of unified standard.Configuration Manager 111 can be subdivided into loader record management submodule and loader document upgrading history management submodule again.The loader recorded information in the loader database of record can be inquired about, adds, revises and be deleted to loader record management submodule.Loader document upgrading history management submodule can be inquired about playing and scheduling module 112 and be recorded in upgrading historical information in the database, comprises the information such as manufacturer, hardware version, software version, upgrading time started and upgrading concluding time of system upgrade software.

Then, playing and scheduling module 112 connects SSU data server 102.In above-mentioned Configuration Manager 111, a manufacturer can be arranged to a service (Service), will become the basic stream (Elementary Stream) under this service to loader file configuration that should manufacturer.Manufacturer's (promptly selecting service) that operator selects current needs to upgrade, select the current loader record (being the basic stream ES under the corresponding with service) that is used to upgrade, and the parameter that the loader file is broadcast information is set, such as the beginning and ending time that upgrading is set, PID that the scope that upgrading is set is selected, the loader document upgrading uses and bandwidth etc.After finishing, setting can send to SSU data server 102 with beginning the instruction that this loader document upgrading broadcasts.Playing and scheduling module 112 also can be by obtaining the parameter that current loader document upgrading of broadcasting is broadcasted with communicating by letter of SSU data server 102, also can with all playing and scheduling operation notes in SSU information database 103, use for Configuration Manager 111.

Wherein, the selection of the scope of upgrading can be according to set-top box sequence number, set-top box batch number or only select according to the hardware-software version of set-top box.The meaning of upgrading by set-top box sequence number or batch number or hardware-software version is, if upgrade at overall network, cable network is owing to the signal quality reason, and what break down on very big coverage rate may be just a lot, the situation that can cause operator to be difficult to deal with.And if upgrade by sequence number, batch number or hardware-software version, then the scope that influenced of upgrading can be limited to a relative small range, the number of faults of appearance will be lacked much relatively.So just can the set-top box in the whole network all be finished once upgrading by continuous small lot upgrading.

Playing and scheduling module 112 can derive the descriptor content of the description upgrade information of SI/PSI needs according to current loader document upgrading broadcasting, be currently to have which loader file of which manufacturer upgrading, their label Tag (also being PID) separately, the information such as selection of upgrading scope.SI/PSI information uses EPG system 301 to broadcast.EPG system 301 receives above-mentioned descriptor, and is inserted in the SI table of appointment, finishes the setting to NIT.As long as the SI/PSI information that guarantees 301 configurations of EPG system and broadcast is consistent with the information reconciliation that playing and scheduling module 112 is used, successfully carries out the loader document upgrading and just obtained guarantee.

SSU data server 102 receives the instruction of broadcasting of playing and scheduling module 112, and loader file and associated control information are transferred to equipment realization broadcasting such as multiplexer 200 by the ASI delivery outlet.

SSU data server 102 can receive transmission stream (TS, i.e. Transport Stream) file of following the packing of integrated system technology using standard, the loader file of not packing and the TS file of each vendor specific form.Code stream package module in the SSU data server 102 adopts different processing modes according to the type of the loader file that receives, and guarantees to send correct upgrade data code stream.Processing mode is as follows: when running into the TS file of vendor specific form, whether check earlier it be legal TS file, and remap according to the PID of appointment; When the loader file of the not packing that runs into the vendor specific form, become the TS file from the Section packing data according to the PID of appointment; And for the DC form not the packing the loader file, at first adopt the digital storage media order and control (DSM-CC, i.e. the Digital StorageMedia-Command﹠amp that use in the integrated system technology using standard; Control) two-layer data carousel (Data Carousel) agreement is carried out the encapsulation of data, and packing generates the TS file, and then row broadcasting.

After the loader file broadcasting, set-top box detects the variation that takes place among the NIT at any time, if carry above-mentioned descriptor among the NIT, set-top box will judge one by one in the loader file of current broadcast whether the loader file that meets it is arranged.Judgement is followed successively by identification of the manufacturer, hardware version, software version in proper order, if be provided with the upgrading scope then need judge also whether the upgrading scope meets self.If above-mentioned condition has all been passed through, then set-top box begins to receive the loader file with identical PID according to the Tag (PID) of appointment in the descriptor, receives the upgrading that the set-top box that resets automatically after also verification finishes is finished systems soft ware.

Whole unified loader system can also comprise an information interaction module, and this information interaction module is used to provide communication interface, realizes and the communicating by letter of external system by this interface.To 0SS, be used to provide the analysis data such as analysis interface before and after upgrading is provided.

In addition, unified loader system has also defined general link Download Descriptor (linkage downloaderdescriptor), has arranged to comprise the parameters relevant with the upgrading scope such as upgrading set top box scope, upgrade area, upgrading colony number, upgrade version this shop, upgrading batch and upgrading manufacturer with set-top box.The combination of these parameters guarantees that operator can select the part set-top box arbitrarily and upgrade, thus avoided owing to manufacturer, version number, batch the negative effect that brings of the set top box upgrading that causes of difference.Operator can carry out upgrading among a small circle earlier, carries out large batch of upgrading afterwards again, guarantees that the problem of user in escalation process is unlikely to break out quickly.
