Description

Digital television program recording method

Technical field

The present invention relates to the application technology of digital TV terminal, relate to a kind of digital television program recording method specifically.

Background technology

Current, the method for recording of digital television program is divided from memory device and can be divided into this locality and record and two kinds of network RECs, and the wherein local access way of recording by memory device can be divided into built-in hard disk and circumscribed USB storage equipment again; Network REC then is that TV programme is stored on the server that operator provides, when the user needs again the mode by program request programme replay is come out.

On the convenience of using, network REC uses more convenient, needn't connect memory device on the set-top box can carry out, and do not influence other program viewings of user when recording fully, but, this service needs operator that network storage space and business support are provided, and generally all needs charge, maybe can only provide free less network storage space for the user.

And this locality is recorded and is needed the built-in big capacity hard disk of set-top box, the cost of set-top box is increased, volume increases; Comparatively speaking, the mode of circumscribed USB storage equipment is more flexible, but needs the user to provide the USB memory device for oneself.If the user does not just in time have this memory device, just can't use this function.

Summary of the invention

Technical problem to be solved by this invention is: propose a kind of digital television program recording method based on home network, solve digital television program recording cost height, the inflexible problem of the mode of recording in the prior art.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: digital television program recording method may further comprise the steps:

A. setting up computer by home gateway is connected with local area network (LAN) between the Digital Television;

B. all in digital TV terminal search and the demonstration local area network (LAN) are opened the computer of procotol ports, and displaying contents comprises computer name and procotol Port IP address;

C. the user selects one of them IP address or computer name, with this computer as program recording storage target;

D. digital TV terminal is gathered the audio, video data of prerecording program and is temporary in the internal memory;

F. digital TV terminal is sent to computer with the audio, video data in the internal memory;

G. computer receives audio, video data and is stored to specified location in user.

Further, comprise that also step h. judges that whether user's designated memory space is sufficient, if not enough, then reminds the user.

The invention has the beneficial effects as follows: the performance recording cost is low, flexibility is strong, selects for user's modes of recording more.

Embodiment

The invention will be further described below in conjunction with embodiment.

The present invention proposes a kind of digital television program recording method based on home network, solve digital television program recording cost height, the inflexible problem of the mode of recording in the prior art, its dominant ideas are: utilize home gateway that digital TV terminal and PC are carried out networking, recorded program is stored in the PC.With respect to prior art, there is following advantage in the present invention: 1. occupation mode is more flexible, the TV programme of using the present invention to record, need not the unloading copy, both can be designed to support directly on PC, to play, also can add the programme content protection, avoid the copyright of TV programme to be on the hazard, also program push can be returned and finish playback on the digital TV terminal according to concrete market demand; 2. compare with local storage mode, need not built-in big capacity hard disk of set-top box or circumscribed USB storage equipment,, just can finish the performance recording function, reduce cost as long as set-top box possesses the RJ45 interface, and convenient storage.3. compare with network storage mode, need not to take the network storage resource of operator's front end, do not take the limited network bandwidth of cell networks or backbone network, also just be not subjected to the restriction of sub-district or backbone network bandwidth simultaneously, strengthened suitable ability greatly.

Embodiment:

Digital television program recording method in this example is to realize on the basis of digital TV terminal, home gateway and PC, also need increase PC control module, digital TV terminal control module, audio, video data acquisition module, data transmission blocks, data reception module and audio, video data playing module on this basis, its concrete implementation step is as follows:

1. the control module on the startup PC, its function are to create a UDP (User Datagram Protocol) or the specific port of TCP (object-oriented connection communication protocol) service, and the prompting user selects the disk position of programs stored recorded content; After creating the port success, wait for that digital TV terminal connects, up to successful connection or the manual execution in step 7 of user;

2. the control module on the operation digital TV terminal, its function is to scan successively in the IP section of home network place, there is which IP to open the serve port of appointment in the above-mentioned steps 1, IP address or the computer name that to open this serve port then show with the form of tabulating, and the prompting user selects one of them address or name to be referred to as the program storage target of digital TV terminal; If the number of results of scanning is 0, then turn to step 7;

3. after the user selects success, between PC and digital TV terminal, just set up point-to-point connection.Rerun audio, video data acquisition module on the digital TV terminal, its function is to be responsible for gathering satisfying the audio, video data of specifying tuner and program parameter condition, and is temporarily stored in the internal memory; Digital TV terminal as described carries a plurality of tuners, need to specify device number, frequency point parameters, symbol rate parameter, the modulation system of tuner this moment, and the Audio PID of program (audio data stream address), VideoPID (video data stream address), Pcr PID (the TV programme locking is with reference to the stream address), if program is an encoded channel, can require according to the content protecting in concrete market to be designed to preserve encrypt or non-encrypted data;
