Embodiment
Can understand other purpose of the present invention, feature and advantage by the reference accompanying drawing to the detailed description of foundation embodiments of the invention.
Below, structure and the effect to the foundation embodiments of the invention is elaborated with reference to the accompanying drawings.As shown in the figure, in order to need at least to describe by 1 embodiment to describing according to the structure of PVR of the present invention system and effect.According to this situation, the then technological thought of the invention described above, core texture, with and effect just unrestricted.
Fig. 1 is the assembly pie graph of expression foundation PVR of the present invention system.
As shown in Figure 1, foundation PVR of the present invention system comprises following components: A/V (Audio/Video) decoder device 101; Encoder apparatus 102; Central control unit 103; Storage reading device 104; Jockey 105; Decoder device 106; A/V encoder apparatus 107.
Above-mentioned A/V decoder device 101 becomes numeral with broadcast singal or external image analog signal conversion, perhaps data form (format) is changed, thereby it is processed into the form that converts numeral easily to.
Above-mentioned encoder apparatus 102 will carry out the dynamic image compression of similar MPEG (Moving Picture Expert Group) coding from the data of above-mentioned A/V decoder device 101 transmission, then data be transmitted to system bus (System BUS).
Simultaneously, the data bit-rate (bit rate) of 103 pairs of above-mentioned encoder apparatus 102 of above-mentioned central control unit is controlled, and receives the data by encoder apparatus 102 transmission.Then, data are transmitted to above-mentioned storage reading device 104.Above-mentioned storage reading device 104 is accepted the control of central control unit 103.Then, will be to the storage device 200 that connects by jockey 105 from the storage of encoder apparatus 102 output.Perhaps the data read that will be stored on the storage device 200 by jockey 105 is come out, and accepts the control of central control unit 103 then, and data are transmitted to decoder device 105.
Above-mentioned storage device 200 is one and can be installed in the PVR system by jockey 105, perhaps the memory device that unloads from the PVR system (memory device).When storage external image or broadcast singal, it just uses as storage medium.When reading the data of having stored, it is exactly the storage medium as PVR system 100 outsides of data read source (source) use.
Above-mentioned jockey 105 is to play interconnect function for the storage reading device 104 with above-mentioned storage device 200 and PVR system 100 couples together, can be easy to make storage device 200 to be installed in the PVR system 100 by it, storage device 200 is separated with PVR system 100.
The effect of above-mentioned decoder device 106 is to decode from the data of above-mentioned storage reading device 104 outputs, thereby converts thereof into A/V encoder apparatus 107 form (format) of identification easily.The signal that above-mentioned A/V encoder apparatus 107 will become television set to receive from the data transaction of above-mentioned decoder device 106 outputs is then with its output.
Below, the storage and the process that reads by foundation PVR of the present invention system are elaborated.
The storage of PVR system 100 and the process that reads are to carry out under the state on the jockey 105 that storage device 200 is installed in PVR system 100.
The data storage procedure of PVR system 100 is that the external image that will be received by PVR system 100 and broadcast data store the process on the above-mentioned storage device 200 into.The external image and the broadcast singal that are received by PVR system 100 carry out digitized processing by above-mentioned A/V decoder device 101, carry out the dynamic image compression by encoder apparatus 102 then, and it is transmitted to storage reading device 104.
Above-mentioned storage reading device 104 is accepted the control of central control unit 103, and the data that receive are stored on the storage device 200 by jockey 105.Like this, just can realize having carried out the storage of signal of video signal by PVR system 100.
On the other hand, the data read process of PVR system 100 is that the data read that is stored on the above-mentioned storage device 200 is come out, and to the process of the display unit of similar TV output.The data that are stored on the storage device 200 read out by storage reading device 104, and above-mentioned storage reading device 104 is accepted the control of central control unit 103, then the data that read out are transmitted to decoder device 106.Above-mentioned decoder device 106 will carry out decoding processing from the data that above-mentioned storage reading device 104 receives, thereby convert thereof into A/V encoder apparatus 107 form (format) of identification easily.A/V encoder apparatus 107 will become the display unit of TV and so on can receive the signal of form through the data transaction that above-mentioned decoder device 106 carries out decoding processing, and export to display unit.Like this, just can realize having read by 100 pairs of data of PVR system.
As mentioned above, storage device 200 is one and is easy to be connected with the PVR system, and the storage device that can separate, and it is installed in the PVR system 100 just can stores broadcast singal or external image data.
Therefore, when external equipment 300 wants to use data by above-mentioned PVR system 100 records, storage device 200 is separated with PVR system 100, be connected storage device 200 just passable with external equipment 300 then.
So even PVR system 100 is not connected with external equipment 300 itself, external equipment 300 also can use the data by PVR system 100 records.
By above-mentioned description, those skilled in the art can carry out various change and modification fully in the scope that does not depart from this invention technological thought.
Therefore, the technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to interest field.
