Abstract
The utility model relates to the field of digital television set top boxes and provides a personal video record playback set top box for conducting optimization design on data storage equipment. The personal video record playback set top box comprises a CPU control circuit, an internal memory, a general input/output control circuit, a storage card interface circuit and a safe digital card, wherein the storage card interface circuit is respectively connected with a safe digital card, the general input/output control circuit, the CPU control circuit and the internal memory; and the CPU control circuit is also respectively connected with the general input/output control circuit and the internal memory. The set top box adopts the safe digital card to replace a hard risk to be the data storage equipment of the personal video record playback set top box, does not increase the volume and weight of the set top box, and has small heating and no noise.
Description
Technical field
The utility model relates to the digital TV set-top box field, the technology of particularly individual video recording playback (PVR) set-top box.
Background technology
Along with the high speed development of Digital Television industry, people can not content just to use set-top box received television program, user to begin to favor set-top box in more high-end; Wherein, the set-top box that has a section directory playing function begins to be subjected to increasing concern.
In view of the problem of TV programme copyright, set-top box can not be to external memory device program recording at present, and therefore existing individual video videocorder top box all is placed in set-top box inside with hard disc of computer as data storage device.But the use of hard disk has greatly increased the volume and weight of set-top box, has brought the problem of Hard disk heat radiation simultaneously, adds hard disk work meeting and produces the hard disk noise, has had a strong impact on user's use.
The utility model content
Technical problem to be solved in the utility model is that a kind of individual video videocorder top box that the data memory device is optimized design is provided.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be, individual video videocorder top box comprises cpu control circuit, internal memory, also comprises general input/output control circuit, memory card interface circuit, safe digital card; The memory card interface circuit links to each other with safe digital card, general input/output control circuit, cpu control circuit, internal memory respectively; Cpu control circuit also links to each other with general input/output control circuit, internal memory respectively.
The beneficial effects of the utility model are, safe digital card has replaced the data storage device of hard disk as individual video videocorder top box, can not increase the volume and weight of set-top box, and little, noiselessness generates heat.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, individual video videocorder top box comprises cpu control circuit, internal memory, GPIO (general input and output) control circuit, memory card interface circuit, safe digital card (SD storage card); The memory card interface circuit links to each other with SD storage card, GPIO control circuit, cpu control circuit, internal memory respectively; Cpu control circuit also links to each other with GPIO control circuit, internal memory respectively.The memory card interface circuit comprises the level pin, and itself and GPIO control circuit are electrically connected.In the SD storage card, is main control chip with the set-top box CPU by the recorded program storage, and has comprised cpu control circuit, internal memory, GPIO control circuit, memory card interface circuit, SD storage card.Treat being stored in the internal memory of recorded program data in real time, when wanting program recording, cpu control circuit judges by the level pin of GPIO control circuit detection of stored card interface circuit whether the SD storage card is inserted on the memory card interface; If cpu control circuit then writes the program data in the internal memory in the SD storage card by the memory card interface circuit immediately immediately, realize performance recording.
