Description
Technical field
The present invention relates to a kind of novel home gateway and operation method thereof, this concrete gateway has receiving digital television, receives the IPTV network flow-medium, the local media resource is play and support the home gateway that a plurality of network equipments are surfed the Net.
Background technology
Along with the development of Digital Television and internet technique, the domestic terminal apparatus of different pieces of information stream format has appearred adopting, as the home gateway of digital TV set-top box, network television-set top-set-box, internet.
Above-mentioned existing family multi-media data equipment adopt the comparatively single asic chip of function usually, thereby cost is relatively low.But, just must dispose the network equipment of many described function singlenesses simultaneously if take into account reception and the broadcast that realizes above-mentioned multiple formatted data stream.Obviously this class only can solve the configuration mode of single formatted data stream, and is unfavorable for the popularization and the use of diverse network technology in family.If buy this network termination type equipment respectively, it is also higher not only to occupy space but also equipment cost, and general family is difficult to bear.Semiconductor technology just develops towards the direction of multiprocessor, high integration at present, the SOC processor that integrated high-speed risc processor nuclear and high-speed dsp signal processor nuclear have occurred, this just is that realization is that the network terminal of one becomes possibility based on domestic. applications, multiple function on single platform.
The gateway product public use of compatible several data stream format is not arranged at present as yet, do not have the operation method of network of relation control technology disclosed yet.
Summary of the invention
The gateway of compatible several data stream format of the present invention and operation method thereof, its purpose is to address the above problem with deficiency provides a kind of compatible CABLE digital television function, receive IPTV network flow-medium function and local media resource playing function, thereby realizes supporting the gateway product and the method thereof of several data stream format.
The gateway of described compatible several data stream format, its application module is that application program is set on the platform of operating system is digital television software module, IPTV web browser software module, local media resource playing module and PVR digital recording module, and the top is the manipulable OSD interface module of user.Various software modules are cured among the FLASH of product by manufacturer when production, and the parameter that needs operator to be provided with then can write in the eeprom memory under the personnel's of producer assistance.
Use described gateway application module, can select to watch the CABLE Digital Television or watch the IPTV network flow-medium by remote controller or panel button at any time as required, also have the function of playing the media article content on local media resource such as USB flash disk or the portable hard drive, can also have the function of PVR digital recording simultaneously.The IPTV network flow-medium comprises Web TV, network film and online music, specifically comprises data formats such as MPEG-1-2-4, WMV9, DivX, RM, RMVB, MP3, WMA.
The operation method of described compatible several data stream format gateway, its operational process is as follows:
The first step, system power on and carry out initialization operation.
One of groundwork that initialization is finished is to start (SuSE) Linux OS, the online local media resource of detection, and detected parameter is write in the sdram memory chip, calls for the OSD subscriber interface module.The OSD subscriber interface module is exported display message after initialization is finished;
Whether initialization operation also detects broadband network and inserts, and carries out validated user authentication registration if broadband network is in access state.System lands and registers according to the content service provider network address that sets in advance in eeprom chip, finishes the authentication registration of validated user automatically, with the holding state that system remains on IPTV network flow-medium function, waits for that the user selects to watch.
In second step, after initialization operation was finished, system carried out the OSD subscriber interface module and receives the instruction that the user sends by remote controller or control panel.
Judge at first, at any time whether the user will be provided with parameter.For example, to turn to digital television function automatically still be parameter settings such as Web TV function after the network address, start of content service provider is set.
If the user has selected the parameter setting, then treat after the user sets up new argument to be kept in the eeprom chip; If do not carry out the parameter setting, then continue to move other functional module.
The 3rd step, the form kind of selection operation data streams or media file.
If the user selects to move certain functional module by remote controller or by control panel, then call corresponding functional modules by the OSD subscriber interface module.
Otherwise, promptly come call number TV functions or IPTV network flow-medium function to play automatically according to the parameter that sets in advance.
As mentioned above, the operation method of compatible several data stream format gateway, adopted the embedded OS Linux of multitask, thereby can carry out calling of PVR digital recording function in digital television function or the operation of IPTV network flow-medium function, thereby Digital Television is recorded in realization or IPTV network flow-medium content is recorded.
As mentioned above, the gateway of compatible several data stream format of the present invention and operation method thereof, its advantage is: have digital television function, IPTV network flow-medium function, local media resource playing function, PVR digital recording function and gateway function, use in the family not only can instead of separate digital TV set-top box, network television-set top-set-box and home gateway product, and can effectively reduce and take up room, reduce equipment cost and economize on resources.
