Description
Technical Field
The invention relates to a novel home gateway and an operation method thereof, in particular to a home gateway which is used for receiving a digital television, receiving IPTV network stream media, playing local media resources and supporting a plurality of network devices to surf the internet.
Background
With the development of digital televisions and internet technologies, home terminal devices adopting different data stream formats, such as a digital television set-top box, a network television set-top box and a home gateway of the internet, appear.
The conventional home multimedia data device usually adopts an ASIC chip with a single function, so that the cost is relatively low. However, if the above-mentioned receiving and playing of the data streams in multiple formats are to be achieved at the same time, multiple network devices with single function must be configured at the same time. Obviously, this kind of configuration mode can only solve the single format data stream, and is not beneficial to the popularization and use of various network technologies in the home. If such network terminal devices are purchased separately, not only space is occupied, but also the device cost is high, and the network terminal devices are difficult to bear in ordinary households. At present, the semiconductor technology is developing towards the direction of multiprocessor and high integration, and an SOC processor integrating a high-speed RISC processor core and a high-speed DSP signal processor core appears, which makes it possible to realize a network terminal with home application as a main part and multiple functions as a whole on a single platform.
At present, no gateway product compatible with a plurality of data stream formats is publicly used, and no operation method of related network control technology is disclosed.

Various software modules are solidified into FLASH of the product by a manufacturer during production of the product, and parameters set by an operator can be written into an EEPROM memory under the assistance of personnel of the manufacturer.
The gateway application module can be used for selectively watching CABLE digital televisions or IPTV network streaming media through a remote controller or panel keys at any time according to needs, has the function of playing media data contents on local media resources such as a U disk or a mobile hard disk, and also has the function of PVR digital video recording. The IPTV network streaming media comprise network televisions, network movies and network music, and particularly comprise data formats such as MPEG-1-2-4, WMV9, DivX, RM, RMVB, MP3 and WMA.
The operation method of the gateway compatible with the multiple data stream formats comprises the following operation processes:
in the first step, the system is powered on and performs initialization operations.
One of the main tasks of initialization is to start the Linux operating system, detect the on-line local media resources, and write the detected parameters into the SDRAM memory chip for the OSD ui module to call. The OSD user interface module outputs display information after initialization is completed;
the initialization operation also detects whether the broadband network is accessed, and performs a legitimate user authentication registration if the broadband network is in an accessed state. The system logs in and registers according to the network address of the content service provider preset in the EEPROM chip, automatically completes the authentication registration of a legal user, keeps the system in a standby state of the IPTV network streaming media function, and waits for the user to select to watch.
And secondly, after the initialization operation is finished, the system executes an OSD user interface module to receive an instruction sent by a user through a remote controller or a control panel.
First, it is determined at any time whether the user wants to set parameters. For example, the network address of the content service provider is set, and the digital television function or the network television function is automatically switched to after the television is turned on.
If the user selects the parameter setting, the new parameters are stored in the EEPROM chip after the user setting is finished; and if the parameter setting is not carried out, other functional modules are continuously operated.
And thirdly, selecting the format type of the running processing data stream or the media file.
If the user selects to operate a certain function module through the remote controller or the control panel, the OSD user interface module calls the corresponding function module.
Otherwise, the digital television function or the IPTV network streaming media function is called according to the preset parameters to automatically play.
As described above, the running method compatible with the gateways with multiple data stream formats adopts the multitask embedded operating system Linux, so that the PVR digital video recording function can be called while the digital television function or the IPTV network streaming media function is running, thereby realizing recording of the digital television or IPTV network streaming media content.
As described above, the gateway compatible with multiple data stream formats and the operation method thereof according to the present invention have the following advantages: the digital television set-top box has the functions of a digital television, an IPTV network streaming media, a local media resource playing function, a PVR digital video recording function and a gateway, can replace a separated digital television set-top box, a network television set-top box and a home gateway product when used in a home, and can effectively reduce the occupied space, reduce the equipment cost and save resources.
