Embodiment 1

[0029] Figure 4 It is the flow chart of the first embodiment of the method of watching and recording realized by the present invention through the secondary cascaded PVR set-top box, the method comprising:

[0030] A. The first PVR set-top box receives all the programs, encodes and decodes the programs of the first frequency in all programs, and outputs them to the TV for users to watch;

[0031] B. The first PVR set-top box sends a control signal to the second PVR set-top box cascaded with it, and the second PVR set-top box receives all the programs through the first PVR set-top box according to the control signal, and compiles the program of the second frequency point in all programs After decoding, save and complete the recording.

[0032] The program at the first frequency point is any one of multiple programs corresponding to the frequency near the first frequency; the program at the second frequency point is centered on the second frequency and near the frequency Any ...

Embodiment 2

[0047] Image 6 It is the flow chart of the second embodiment of the method of watching and recording realized by the present invention through the secondary cascaded PVR set-top box, the method comprising:

[0048] A. The first PVR set-top box receives all the programs, encodes and decodes the programs of the second frequency point in all programs, saves them, and completes the recording;

[0049] B. The first PVR set-top box sends a control signal to the second PVR set-top box cascaded with it. The second PVR set-top box receives all the programs through the first PVR set-top box. The PVR set-top box outputs to the TV for users to watch.

[0050] Further, B specifically includes:

[0051] The first PVR set-top box sends a program viewing control signal to the second PVR set-top box cascaded with it, and opens the loop-through function of the video signal input and output interface of the first PVR set-top box, and opens the loop-through function of the transmission stream ...

Abstract

The invention relates to a cascade personal video recorder (PVR) set top box and a method for recording a video in the process of watching the video by using the cascade PVR set top box. The cascade PVR set top box comprises a first PVR set top box and a second PVR set top box, wherein a control signal input interface and a control signal output interface are formed on each set top box; a transmission stream signal input interface of the first PVR set top box is connected with a signal source; a video signal output interface is connected with a television; a transmission stream signal input interface of the second PVR set top box is connected with the transmission stream signal input interface of the first PVR set top box; the video signal output interface is connected with a video signal input interface of the first PVR set top box; and the control signal input interface is connected with the control signal output interface of the first PVR set top box. By the cascade PVR set top box and the method, a user can select a program from other channels flexibly when a program of a channel is recorded without any limitation.

Description

technical field [0001] The invention belongs to the technical field of set-top boxes, and in particular relates to a cascaded PVR set-top box and a method for realizing recording while watching through the cascaded PVR set-top boxes. Background technique [0002] With the development of hard disk technology, hard disk-based PVR (personal video recoder, personal video recorder) has become a new type of consumer product, and began to replace tape video recorders. Combining PVR technology with digital set-top boxes, it has become a PVR set-top box. [0003] Existing technologies such as figure 1 As shown, the PVR set-top box includes: video signal input interface, video signal output interface, transport stream signal input interface, transport stream signal output interface, main chip and recording module, the video signal output interface is connected to the TV, and the transport stream signal input interface is connected to the signal source connected. When the user needs ...
