As shown in fig. 1, a video processor provided in a first embodiment of the present invention includes: the back panel device 10 comprises a matrix switching module 11, and the matrix switching module 11 is connected between the video input processing device group and the video output processing device group. The matrix switching module 11 includes, for example, a high-speed matrix switching chip such as a CrossPoint Switch chip; the video input processing device group includes, for example, video input processing devices 21, 22, 23, and 24; the video output processing device group includes, for example, video output processing devices 32, 33, and 34 and a video output processing device configurable as the multi-signal-source pre-monitoroutput device 31.
Furthermore, the video input processing devices 21 to 24 can realize video input, video pre-processing, even video scaling, video pre-monitoring, OSD (on-screen display), umd (under Monitor display), and other functions. The video preprocessing is operations such as Gamma (Gamma) conversion, color gamut conversion (e.g., YUV format to RGB format), filtering (e.g., median filtering), and the like. The video output processing devices 32, 33 and 34 and the multi-signal source pre-monitoringoutput device 31 can realize functions of image scaling, image superposition, video output and the like.
In light of the above, when the video processor operates in the multiple signal source pre-monitor mode, any one of the video output processing devices in the video output processing device set may be configured as the multiple signal source pre-monitoroutput device 31, and other video output processing devices in the video output processing device set, such as the video output processing device 32, the video output processing device 33, and the video output processing device 34 shown in fig. 1, are connected to the multiple signal source pre-monitoroutput device 31 via the matrix switch module 11 to transmit the respective signal source to be pre-monitored to the multiple signal source pre-monitoroutput device 31. The video output processing device 32 transmits its own signal source to be pre-monitored to the multi-signal-source pre-monitoringoutput device 31, where the number of the signal sources to be pre-monitored is two, and the two signal sources are, for example, a current playing signal source (or pgm (programming) signal source, which is usually a signal source currently output for on-screen display) and a pre-monitoring output signal source (or pvw (pre view) signal source, which is usually used as a next playing signal source after pre-monitoring), and the positions of the current playing signal source and the pre-monitoring output signal source on the multi-signal-source pre-monitoring screen are, for example, as shown in P5.1 and P5.2; the video output processing device 33 transmits its own signal source to be pre-monitored to the multi-signal-source pre-monitoringoutput device 31, where the number of the signal sources to be pre-monitored is two, for example, the current playing signal source and the pre-monitoring output signal source, and the positions of the current playing signal source and the pre-monitoring output signal source on the multi-signal-source pre-monitoring picture are shown as P6.1 and P6.2, for example; the video output processing device 34 transmits its own signal source to be pre-monitored to the multi-signal-source pre-monitoringoutput device 31, where the number of the signal sources to be pre-monitored is two, for example, the current playing signal source and the pre-monitoring output signal source, and the positions of the current playing signal source and the pre-monitoring output signal source on the multi-signal-source pre-monitoring picture are shown as P7.1 and P7.2, for example.
It should be noted that, while a plurality of video output processing devices are included in the video processor, the video output processing device group in this embodiment particularly defines a part of the video output processing devices that need to perform the pre-monitoring output operation, i.e., the video output processing device group is composed of at least two video output processing devices (including the multi-signal source pre-monitoringoutput device 31 and another one or more video output processing devices). The video output processing apparatus set in this example includes the multi-signal source pre-monitoroutput apparatus 31, the video output processing apparatus 32, the video output processing apparatus 33, and the video output processing apparatus 34, but the number of video output processing apparatuses included in the video output processing apparatus set is not limited thereto.
Meanwhile, the video input processing device 21, the video input processing device 22, the video input processing device 23, and the video input processing device 24 in the video input processing device group are connected in cascade via the matrix switch module 11 (for example, as shown by the dotted line in fig. 1), and the last-stage video input processing device 24 is connected to the multi-signal-source pre-monitoringoutput device 31 via the matrix switch module 11 to transmit all the signal sources to be pre-monitored accessed by the plurality of video input processing devices 21-24 to the multi-signal-source pre-monitoringoutput device 31, and the multi-signal-source pre-monitoringoutput device 31 is configured to generate and output a multi-signal-source pre-monitoring picture according to the plurality of signal sources to be pre-monitored including the signal sources to be pre-monitored provided by the video output processing devices 32-34 and the signal sources to be pre-monitored provided by the video output processing devices 21-.
In addition, the latter video input processing device of the multiple video input processing devices 21-24 is used for performing the overlay processing on the signal source to be pre-monitored, which is accessed by the latter video input processing device, and the signal source after the overlay processing from the former video input device to obtain another signal source after the overlay processing, and outputting the signal source. Specifically, the video input processing device 21 performs superposition processing on its own accessed signal sources to be pre-monitored to form superimposed signal sources, where the two signal sources to be pre-monitored are, for example, two and their positions on the multi-signal-source pre-monitoring picture are, for example, as shown in P1, and then the superimposed signal sources are transmitted to the video input processing device 22 through the matrix switching module 11; the video input processing device 22 superimposes the signal source to be pre-monitored that is accessed by itself, for example, two signal sources to be pre-monitored that are accessed by itself and the position of the superimposed signal source from the video input processing device 21 on the multi-signal-source pre-monitoring picture, for example, as shown in P2, with the superimposed signal source from the video input processing device 21, and superimposes the superimposed signal source again to form another superimposed signal source; then, the video input processing device 23 superimposes the signal source to be pre-monitored that is accessed by itself, for example, two signal sources to be pre-monitored that are accessed by itself and the position of the superimposed signal source from the video input processing device 22 on the multi-signal-source pre-monitoring screen are, for example, P3, and so on, so that the fourth superimposed signal source can be formed on the video input processing device 24, and the position of each superimposed signal source to be pre-monitored on the multi-signal-source pre-monitoring screen is, for example, P4.
In this embodiment, the superimposed signal source received by the video input processing device 22 from the video input processing device 21 and the superimposed signal source output by the video input processing device 22 share the same serializer/deserializer bus for transmission; similarly, the superimposed signal source received by the video input processing device 23 from the video input processing device 22 and the superimposed signal source output by the video input processing device 23 share the same serializer/deserializer bus for transmission; the superimposed signal source received by the video input processing device 24 from the video input processing device 23 and the superimposed signal source output by the video input processing device 24 share the same serializer/deserializer bus for transmission; thus, occupation of the serializer/deserializer bus channel can be greatly reduced.
In the present embodiment, the multi-signal-source pre-monitor processing is performed by the multi-overlap processing, and the pre-monitor screen P8 finally outputted by the multi-signal-source pre-monitoroutput device 31 is partially overlapped or not overlapped.
As mentioned above, for the video output processing device 32, the video output processing device 33 and the video output processing device 34 in the video output processing device set, the signal sources to be pre-monitored, which are respectively transmitted to the multi-signal-source pre-monitoroutput device 31, for example, all include the currently playing signal source and the pre-monitor output signal source, and the currently playing signal and the pre-monitor output signal source are respectively transmitted to the multi-signal-source pre-monitoroutput device 31 through the matrix switching module 11 through two serializer/deserializer buses, that is, each of the video output processing devices, such as the video output processing device 32, the video output processing device 33 and the video output processing device 34, is connected to the matrix switching module 11 through two serializer/deserializer buses for transmitting two signal sources to be pre-monitored.
Further, in the present embodiment, the multi-signal-source pre-monitoroutput device 31 can perform, in addition to the overlay processing on the signal sources to be pre-monitored from the video output processing devices such as 32-34 and the video input processing devices such as 21-24, the non-overlapping overlay processing on the current playing signal source and the pre-monitor output signal source of the multi-signal-source pre-monitor output device and all the received signal sources to be pre-monitored together to generate the multi-signal-source pre-monitor picture P8.
In summary, the video input processing devices 21-24 of the video processor of the present embodiment are connected to the multi-signal source pre-monitoroutput device 31 in a cascade manner through the matrix switch module 11, and in a cascade manner, for transmitting all the signal sources to be pre-monitored accessed by itself to the multi-signal source pre-monitoringoutput device 31, and the multiple video output processing devices 32-34 are connected to the multiple signal source pre-monitoringoutput device 31 via the matrix switch module 11 to transmit the respective signal sources to be pre-monitored to the multiple signal source pre-monitoringoutput device 31, and the multiple signal source pre-monitoringoutput device 31 generates and outputs a multiple signal source pre-monitoring picture P8 according to all the received signal sources to be pre-monitored, even in combination with the signal sources to be pre-monitored, the need for a transmission channel for the serializer/deserializer bus can thus be greatly reduced, while reducing cost.
