Description
Technical field
The invention belongs to set-top box technique field, relate in particular to a kind of cascade PVR Set Top Box and by cascade PVR Set Top Box, realize the method for recording while seeing.
Background technology
Development along with seagate, PVR based on hard disk (personal video recoder, personal video record) has become novel consumer product, starts to replace magnetic tape type video tape recorder, PVR technology and top box of digital machine are combined, just become PVR Set Top Box.
Prior art as shown in Figure 1, PVR Set Top Box comprises: video signal input interface, video signal output interface, transmission stream signal input interface, transmission stream signal output interface, master chip and record module, video signal output interface is connected with TV, and transmission stream signal input interface is connected with signal source.When user need to see program, master chip carries out encoding and decoding to the signal receiving from transmission stream signal input interface, then the program after encoding and decoding is sent to TV by video signal output interface, for user, watches; When user need to record program, master chip carries out encoding and decoding to the signal receiving from transmission stream signal input interface, then by the program sending after encoding and decoding to recording module, record module to recording program and be kept on hardware device.
If user, in a program of record, also wants to see other programs simultaneously, the PVR Set Top Box of prior art just can only offer the limited program of user and select.Because the master chip of PVR Set Top Box once can only carry out encoding and decoding to all programs of a frequency, after encoding and decoding, master chip need to be sent into one of them program to record module according to user, other programs under this frequency is offered to user and select to watch.For example, the program frequencies that Set Top Box receives is probably at 200MHz-858MHz, frequency 1 is 300MHz left and right, and frequency 2 is 500MHz left and right, and frequency 3 is 600MHz left and right, frequency 1,2,3 each frequency probably comprise 10 programs, when user selects to record the program of frequency 1, master chip can only carry out encoding and decoding to all programs of frequency 1, after encoding and decoding, master chip is sent into one of them program to record module, other 9 programs under this frequency is offered to user and select to watch.Master chip is occupied, can not carry out encoding and decoding to the program of other frequencies, so user can only see a few program.
Summary of the invention
Technical problem to be solved by this invention is that user, when using PVR Set Top Box record program, can see program simultaneously, for user, selects the program number of seeing can not be affected because of record program.
