By adopting the system of the invention, the set-top box can freely choose the different operator network according to the requirement of the user; the set-top box can be separated from the concrete application service, the assess mode of the set-top box is simplified into an IP household network, and the function of the set-top box is specified into the decoder of a multimedia digital compressed stream and a user input collector to lead the integration of the set-top box and the television to be possible.
Description
Technical field
The present invention relates to digital TV field, relate in particular to Internet Protocol Television and cable digital TV application technology at subscriber household.
Background technology
Along with the development of digital television techniques with popularize, digital TV set-top box is becoming the standing terminal equipment of digitized home.Set-top box connects multi-media network and television set, shows multimedia messagess such as the video that receives from multi-media network, audio frequency, picture, literal to the user by TV, and the user also can transmit various input informations to multi-media network by set-top box.
The form that multi-media network inserts family is varied, both can be cable television, also can be xDSL (various digital subscriber line) or FTTH IP network such as (fiber-to-the-home front yards).Corresponding to different service provider, the access protocol of multi-media network also may be different.Thereby cause supporting that the set top box network interface of each Operator Specific Service is incompatible.
Decoding need expend the set-top box ample resources through compressed digital signal, and set-top box should not be far away excessively with the connection distance of television set in addition, and stride the use habit that room controller top box does not meet the user yet, thereby set-top box only is connected with a television set mostly.
For these reasons, if many television sets in each room that is dispersed in family are arranged in the one family, then the user not only to need be that every television set is equipped with a set-top box, and need be each room prepare one with the corresponding network interface of set-top box.If change operator, then the user not only needs to rearrange the network interface in each room, and needs to change whole set-top box.Under complicated situation more, if the user buys the service of a plurality of operators simultaneously, then every television set need be equipped with a plurality of set-top box, and a plurality of network interfaces need be prepared in each room, otherwise the user can't watch the program of all operators on arbitrary TV.And be that the set-top box that each TV is equipped with all operators has caused great waste to the user, the user not only needs to buy set-top box, also needs to buy the program mandate for every TV to each operator.The user wishes that more each television set can share the multi-media network interface.
Above-mentioned situation also freely selects program source and operator to be provided with obstacle to the user technically.Be unfavorable for competition, popularization and the development of digital television business.
Because set-top box and operator be incidence relation too closely, set-top box also is difficult to merge with television set, and this had both increased purchasing of user and maintenance cost, and also operating to the user has increased extra burden.
Prior art has proposed family multi-media network struture system, attempts to solve the problems referred to above by a plurality of network interface unit (NIU) method corresponding with a plurality of set-top box.But, because in this scheme, the functional definition of interface unit and set-top box is not clear, can not realize that set-top box and operator are irrelevant, its practicality is not high.
Summary of the invention
The present invention is directed to the drawback of set-top box and operator and network interface binding tension, proposed to be applied to the multimedia access system of home network, thereby function clear and definite and the simplification set-top box, the fusion of set-top box and TV can be promoted, also the obstacle that the user selects program operator can be eliminated technically.
The technical solution adopted in the present invention is:
