Embodiment

Below describe in detail with reference to the accompanying drawings at invention structure and effect.

What Fig. 1 showed is to play the flexible using method of memory space that receives with PVR IRD system according to multiple units digital satellite of the present invention.

Said system is controlled in many rooms and is utilized WLAN (wireless local area network) (LAN) to connect a plurality of PVR IRD system under (Multi-room) environment.

As shown in Figure 1, multiple units PVR IRD system receives as NTSC, play signal such as ATSC or digital satellite play signal link to each other with WLAN (wireless local area network) with above-mentioned server to the server I RD of the medium by PVR (abbreviate as ' memory space of IRD ' or ' HDD ' of IRD) with storage simultaneously.Same medium is constituted with a plurality of clients (Client) IRD of storage.In the middle of the above-mentioned server I RD, WLAN (wireless local area network) hub (Hub) is installed, therefore can links to each other, carried out wireless LAN communication by this with above-mentioned most client IRD.

The PVR IRD System Operation relation that so constitutes is as follows.

When using the user of above-mentioned client IRD 1 to want to record program, suppose that the hard disk usage space of client IRD 1 is very abundant, directly use this space to get final product.

But as shown in Figure 1, client IRD 1 causes the deficiency of memory space because almost use memory space.

At this moment, client IRD 1 can be in network retrieval at present not behind in use other IRD, supposing has its sufficient space at the IRD that retrieves, the IRD memory space that will use at it is recorded the method for program.

What Fig. 2 showed is exactly aforesaid IRD retrieval and recording stage.

As shown in Figure 2, the stage that IRD retrieves and recording stage roughly is divided into the IRD retrieval phase and the IRD that retrieves is carried out recording request and records.

The stage of abundant memory space IRD is searched at present not in use, had to above-mentioned IRD retrieval phase on network.

Client IRD 1 in using at present sends in order to obtain whether using at present and the information of spendable storage space volume of IRD to client IRD 2 by server I RD.

Then, client IRD 2 can send the information that contains current state to client IRD 1.Above-mentioned client IRD 1 judges whether and can record by above-mentioned state information.

At this moment, when client IRD 2 is not enough to record, can retrieve other IRD.In appropriate circumstances, turn to the IRD that retrieves and carry out recording request and recording stage.

Above-mentioned recording request is in the stage, can send to the IRD that retrieves to contain for the channel recorded and the information of program information (time started, concluding time), requires to record.The client IRD 2 that is required sends to client IRD 1 and records start information, thus the beginning recording stage.

When finishing above-mentioned recording, client IRD 2 sends to client IRD 1 and records ending message, thereby finishes to record.

The program of recording is like this play by follow-up user's process, and this process has been presented at Fig. 3 to Fig. 5.

What Fig. 3 represented is the program of recording that IRD kept separately.

As shown in Figure 3, the user of the client IRD 1 in using at present can use two kinds of methods in the time need playing the program of recording.First is exactly to retrieve the program directory that HDD is recorded in the client IRD 1 and play required program; Second is exactly the program directory that retrieval is recorded in other IRD (server I RD, client IRD 2), thereby plays the method for required program.At this moment, consider user's grade (for example: under-18s, less than 12 years old) of client IRD 1, be controlled to be and retrieve and to play the program of permission.

Above-mentioned second method promptly retrieved the program directory stage that other IRD hold and is presented among Fig. 4.

As shown in Figure 4, the program that the client IRD 1 in using is at present recorded to client IRD 2 requirements, above-mentioned client IRD 2 meetings send to the program directory information of recording in the middle of the above-mentioned client IRD 1.

Can retrieve the program directory that each IRD holds by these process clients IRD 1, and the user of client IRD 1 selects to play required program by the program directory that retrieves.

So, can play during HDD in the procedure stores that will the play IRD in use, but when the HDD of other IRD, require to play required program to its IRD.

Fig. 5 shows is to play the program process of storing among the HDD of other IRD of recording.

As shown in Figure 5, when playing required program at client IRD 2 in the program of retrieval, client IRD 1 can send program information and the broadcast request information that hope is play to above-mentioned client IRD 2.

After this, client IRD 2 reads the program that is required from the HDD of client IRD 1, sends by WLAN (wireless local area network).

Above-mentioned client IRD 1 plays after receiving the program of client IRD 2 transmissions constantly.

By the content of above explanation, if relevant practitioner can carry out abundant variation and modification in the scope that does not break away from technological thought of the present invention.

Then, technical scope of the present invention is not to be confined to the content put down in writing, but depends on patent claim.
