Abstract
The invention discloses a method for downloading multimedia data from a digital television network and storing the data in USB interface storage equipment. The method provides users using integrated digital television and digital television set top boxes with such a function that the multimedia data can be played and used at any time after downloading the multimedia data.
Description
Technical field
The present invention is a kind of application that the digital TV field multi-medium data is downloaded, digital TV terminal specifically, particularly digital TV integrated machine, digital TV set-top box are used a kind of application of the multi-medium data of USB interface device storage digital television system broadcasting.
Background technology
MP3: the abbreviation of English " MPEG Audio Layer-3 ", one of compression standard of voice data.MPEG that is " Motion Pictures Expert Group " can be translated into Motion Picture Experts Group in Chinese, this is a global organization that is devoted to video compression exploitation manufacturing and platform separate standards.MP3 refers in particular to the music file of MP3 format in this explanation.
USB: the abbreviation of English " Universal Serial Bus " is commonly referred to as USB.
Digital television broadcasting provides data unload function, main at present the application is the upgrading of digital TV terminal device software system, content generally is that the body carried out of software systems is done data after the corresponding conversion, by the self-defined file format of download system manufacturer, because the set-top box internal storage space is less, institute of this system downloaded files can only be stored less a part of data in the digital TV terminal memory, or does not only store and handle; Digital TV terminal equipment in the past seldom has the USB interface chip, and USB interface-based application is also few, a kind of application that multi-medium data is stored in real time the USB interface memory device do not occur always.
Summary of the invention
The digital TV terminal equipment of USB interface chip has appearred having at present, and USB interface can articulate memory devices such as USB flash disk, portable hard drive, purpose of the present invention just provides a kind of method of utilizing digital tv network download multi-medium data and being stored in the USB interface memory device, so that digital television terminal user is play the multimedia file in the USB interface memory device at any time.
At digital TV front-end, MP3 is arranged, audio-video documents such as WMA, these files are loading source, utilize multimedia software, the private data section of the packing data in these files to transport stream, a the rendition list of can packing simultaneously, then multimedia software utilize code flow broadcast card these data playback to equipment such as modulator-demodulator, modulator-demodulator is these data-modulated and deliver in the digital TV network.
At digital TV terminal, the user passes through digital television terminal equipment, as digital TV integrated machine or digital TV set-top box, set the multimedia download list that corresponding modulation parameter finds front end to broadcast, when selected want downloaded contents after, digital TV terminal equipment takes out and is reduced into the preceding data format of broadcast to the related data in the digital TV network according to the packing form of front end, then these data is written in the memory device by USB interface.
Description of drawings

Fig. 2 realizes digital TV front-end Play System figure of the present invention
Fig. 3 realizes digital TV terminal download MP3 flow chart of the present invention
Embodiment
In this example, the multi-medium data source is example with MP3, Figure 1 shows that the MP3 broadcast system, can finish MP3 Play Server function by a computer, Play Server needs configuration bit stream to play card and MP3 is installed to play application software (function of this playout software is the MP3 packing data and sends).Modulator is modulated the code stream of Play Server output and deliver in the digital TV network.
Digital TV network is the carrier and the approach of digital TV front-end institute broadcast data.
Digital TV terminal is except can the receiving digital television program and play these programs and watch etc. the general function that receiving equipment had for users, also possesses the USB interface device driver that normally to move, modules such as file system are to articulate the USB interface memory device, to realize the storage after multi-medium data is downloaded.
Fig. 2 digital TV front-end Play System mainly is made up of MP3 Play Server and modulator-demodulator, and the MP3 Play Server mainly contains the mp3 file source, and MP3 plays module of software and hardware such as instrument and code flow broadcast card.
MP3 is that the form with the private data table exists in transport stream, two parts content is arranged, listed files and MP3 song data.The function that MP3 plays instrument is to gather the mp3 file data, then these data according to the packing of certain form (formal definition that these two parts data can realize can with reference to ISO/IEC 13818-1), call code flow broadcast card then and drive these data are sent to modulator-demodulator by code flow broadcast card, send several subfunctions so this instrument is divided into data acquisition, data packing, data again.
Fig. 3 is that digital TV terminal is downloaded flow process, the digital TV terminal receiving digital television signal, and analyzing and processing corresponding data bag writes the USB interface memory device to the MP3 data that obtain then:
1. the user selects to start the mp3 file download function of digital TV terminal equipment by the menu of digital TV terminal.At digital TV terminal, whether the download of MP3 carries out menu by the user by input equipment (remote controller, front panel, keyboard etc.) is selected, and the user can start this download function at any time to download mp3 file.
2. whether digital TV terminal is used at first to detect to have and can be downloaded the MP3 song, method is to pin the frequency (informing these information by operator) that MP3 downloads the place by digital tuner earlier, then transport stream is carried out data extract, can download MP3 if having, the MP3 table data can be broadcasted in digital TV network always, so digital TV terminal can extract related data, list at display interface so and can download the mp3 file title, confession users such as size select to download, if no, prompting user and returning.
3. when the user interested in certain or some the MP3 song in the download list, by selected this song of user input device (remote controller, front panel, keyboard etc.).Certainly the user also can cancel download.
Whether at this moment at first detect the USB interface memory device inserts, if no, then point out the user to insert, and selected again download song, confirm that the USB interface memory device has inserted and by normal identification of terminal system and loading, terminal system just can write file when receiving data so.
4. terminal system is called file system function according to song title and length etc. and is created mp3 file, and this document writes in order to the MP3 data at any time just in data download previous crops preparation.This document is empty when creating, and following returning may be arranged: file of the same name exists; The document creation failure; The document creation success.If file of the same name exists, can point out the user whether to replace this document so, finally be to create failure or success, if create failure, this time failed download returns so.
5. after creating the file success, terminal system is called bottom data and is extracted driving reception MP3 data, the format specification of playing according to front end receives and analyzes, these data of back or through handling again by analysis, or without handling again, write 4. the file of creating successively, just write the USB interface memory device, until the MP3 song is received or overtime up to receiving the mp3 file data.
6. close file.
In conjunction with the accompanying drawings the specific embodiment of the present invention has been carried out exemplary description above; but it is not in order to limit the present invention; any person skilled in the art person without departing from the spirit and scope of the present invention; can make various changes and replacement, so protection scope of the present invention is when looking being as the criterion that accompanying Claim defines.
