Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In addition, the SDI (Serial Digital Interface ) signal of the existing 8K system can only be synchronously transmitted as one path by 4 paths, and the system is complex in connection and has many connecting lines; meanwhile, since the related technology of the SDI has longer service time and many components are connected by the SDI, the construction of the 8K system is difficult to be made by considering 4K. The use of IP (Internet Protocal, internet protocol) for transmission can solve the problem of multiple connections, but since the related art of SDI has a long service life, many components in the system use SDI connections, so the simplification of the system by the IP connections, the versatility and availability of SDI, are required to be considered when designing the system, but the current system is difficult to realize.
Based on the above, the embodiment of the invention provides a 4K and 8K mixed follow-up ultra-high definition field production system which can be applied to production of 8K video programs and production of 4K video programs. As shown in fig. 1, the system includes: an 8K switching stage 10, a 4K switching stage 11, an up-converter 12, and a follow-up control device 13; the follow-up control device 13 is respectively connected with the 8K switching table 10 and the 4K switching table 11; the 4K switching stage 11 is also connected to an up-converter 12.
The 8K switching station 10 is configured to receive an input M-path 8K input signal; the 8K switching station 10 is also configured to receive the 1-way 8K signal output from the up-converter 12. M is typically a positive integer greater than 0. The 8K input signal may be an 8K signal output from an 8K signal source, or may be an 8K signal after up-conversion of a 4K signal. The 8K switching station is usually used for multi-camera studio or outdoor scene production, and is a device for connecting selected videos through cutting, overlapping pictures and dividing pictures, and further creating and embedding other special effects to complete program production.
The 4K switching station 11 is configured to receive M4K input signals having the same content (usually, only different resolution and the same content) as the M8K input signals; meanwhile, the 4K switching station 11 is further configured to receive N paths of 4K input signals input by the 4K signal source, and complete switching and on-site fabrication of m+n paths of 4K input signals, so as to output 4K PGM (Program) signals; the access sequence of the first M paths of 4K signals of M+N paths of 4K input signals in the 4K switching station is consistent with the access sequence of the first M paths of 8K signals in the 8K switching station. N is typically a positive integer greater than 0.
For example, assuming that M is 8 and n is 32, the 4K switching station may receive 8 paths of 4K signals having the same content as 8 paths of 8K input signals transmitted by the 8K signal source, and may also receive 32 paths of 4K input signals transmitted by the 4K signal source, that is, the 4K switching station receives 40 paths of 4K signals in total; the 4K switching station can switch and manufacture the 40 paths of 4K signals on site to obtain 4K PGM signals.
The follow-up control device 13 is configured to receive an operation control instruction sent by the 4K switching station 11, and forward the operation control instruction to the 8K switching station 10; the 8K switching station 10 receives the operation control command forwarded by the follow-up control device 13, and completes switching and making of the m+1 path 8K signal under the control of the operation control command, so as to output an 8K PGM signal. The m+1-path 8K signal here includes the M-path 8K input signal received by the 8K switching station 10 and the 1-path 8K signal output by the up-converter 12. The 4K switching table forms an operation control instruction according to the operation action of an operator on the operation panel.
The 4K switching station 11 is further configured to send a 4K PGM signal to the up-converter 12; the up-converter 12 is used to convert the received 4K PGM signal into an 8K signal.
According to the 4K and 8K mixed follow-up ultra-high definition field manufacturing system, follow-up manufacturing of 8K ultra-high definition video and 4K ultra-high definition video can be achieved, so that the 8K video can be output along with the 4K video, two paths of original ultra-high definition video program signals with different resolutions and the same content and different content are generated at the same time, program output with the highest picture quality is guaranteed, an operator is not needed at an 8K switching station, and human resources are saved.
In addition, by switching the system configuration, the 4K production system is switched to the 8K production system, and the expansion of the processing capability of the 8K video signal can be realized.
The embodiment of the invention also provides another 4K and 8K mixed follow-up ultra-high definition field manufacturing system, which is realized on the basis of the embodiment; as shown in fig. 2, the system includes an 8K switching stage 10, a 4K switching stage 11, an up-converter 12, and a follow-up control device 13.
Specifically, the 8K switching station 10 includes: an 8K switching station host 100, an 8K switching station control panel 101, and an 8K switching station controller 102; wherein, the 8K switching station controller 102 is respectively connected with the 8K switching station control panel 101 and the 8K switching station host 100; the 8K switching station host 100 receives the control of the 8K switching station controller 102, and completes the switching and the manufacturing of M+1 paths of 8K signals; the 8K switching station control panel 101 is configured to provide an operation interface, so that the 8K switching station controller 102 controls the 8K switching station host 100 through an operation instruction in the operation interface.
In a specific implementation, the 4K switching station 11 includes: a 4K switching station host 110, a 4K switching panel 111, and a 4K switching controller 112; the 4K switching controller 112 is connected to the 4K switching panel 111 and the 4K switching station host 110, respectively; the 4K switching host 110 receives the control of the 4K switching controller 112, and completes the switching and the manufacturing of the received multipath 4K input signals and 4K signals; the 4K switching panel 111 is used for providing an operation interface, so that the 4K switching station controller 112 controls the 4K switching station host 110 through an operation instruction in the operation interface.
In practical applications, the 8K switching station 10 has two operation modes: an independent working mode and a follow-up manufacturing mode. When the 8K switching station 10 is in the independent operation mode, the 8K switching station controller 102 converts the operation of the 8K switching station control panel 101 into an operation control command and sends the operation control command to the 8K switching station host 100, so that the 8K switching station host completes the switching and the production of the received 8K signal.
When the 8K switching station 10 is in the follow-up production mode, the 8K switching station controller 112 receives the operation control instruction of the 4K switching station 11 forwarded by the follow-up control device 13, converts the operation control instruction of the 4K switching station host 110 into the operation control instruction of the 8K switching station host 100, and transmits the operation control instruction to the 8K switching station host.
Specifically, the rule of instruction conversion includes: if the operation control command of the 4K switching station 11 involves only the first M paths of 4K signals, correspondingly converting the first M paths of 4K signals involved in the operation control command of the 4K switching station host 110 into operation control commands of the same type involving 8K signals of corresponding sequence numbers; if the operation control instruction of the 4K switching station 11 involves the m+1th to m+nth 4K signals, the operation control instruction of the 4K switching station host 110 is converted into an operation control instruction to cut out the m+1th 8K signal.
As shown in fig. 3, the manufacturing system of the present invention further includes: an 8K switch 21 and an 8K signal source 22; the 8K signal source 22 is connected with the 8K switching station 10 through the 8K switch 21; the 8K switching station 10 is an IP switching station, and the signals after up-conversion of the 8K signal source 22 and the 4K PGM signal are signals in IP format. The 8K signal source 22 may be an 8K camera, an 8K video recorder, or other device that may provide an 8K signal.
Further, the production system in the present application further includes an IP converter 23; the IP converter 23 is connected to the 8K switch 10 and the up-converter 12; the IP converter is used to convert an 8K IP signal into an 8K SDI signal or to convert an 8K SDI signal into an 8K IP signal.
Specifically, the 8K signal source 22 described above can output an 8K IP signal and a 4K SDI signal which are identical in content and differ only in resolution. In practical applications, the 8K signal source 22 can output an 8K signal (the 8K signal is an IP signal, the IP signal includes a transmitted destination address, where the destination address refers to an IP address of the 8K switching station), and input the 8K signal to the 8K switching station through the 8K switch 21, where the 8K switching station selects one or more signals from the received 8K signals including multiple paths to make, and then sends the made 8K PGM signal (the PGM signal is also an IP signal) to the IP converter through the 8K switch and the NMI server, where the IP converter converts the 8K PGM signal in the IP format into the 8K PGM signal in the SDI format.
In practical applications, if the 8K signal source includes a monitor (e.g., a small display screen in an 8K camera), the IP converter may send one of the 8K PGM signals to the monitor in the 8K signal source, so that the photographer knows the picture currently being played.
The 4K switching station may receive multiple 4K signals in SDI format, and there are two sources of these 4K signals: one may be a 4K signal directly derived from the output of the 4K signal source (the 4K signal is an SDI signal), or a part may be a 4K signal derived from the output of the 8K signal source (the 4K signal is an SDI signal); the 4K signal output by the 8K signal source can be directly output by the 8K signal source or can be the 4K signal which is down-converted by the 8K signal source, the 4K switching station selects one or more paths of signals from the multiple paths of signals to manufacture, and the manufactured 4K PGM signal (the main output is also the ultra high definition video signal in the SDI format) is output; the output 4K PGM signal can be performed as follows:
(1) Can be directly sent to the SDI peripheral equipment of 4K.
(2) Can be sent to an up-converter, up-convert the 4K PGM signal into an 8K signal (the 8K signal is an SDI signal) and then send to an 8K SDI peripheral device; in this case, the 4K PGM signal program produced by the 4K switching station can be up-converted into a 1-channel 8K program output.
(3) The 4K PGM signal may be up-converted into an 8K signal by an up-converter and the 8K signal may be transmitted to an IP converter, the 8K signal in SDI format may be converted into an 8K signal in IP format by the IP converter and the converted 8K signal may be transmitted to an 8K switching station via a switch, and the received signal may be further fabricated by the 8K switching station.
Further, the manufacturing system further comprises an N-channel down-converter; the N-way down-converter is used to down-convert the N-way 8K signal into an N-way 4K signal.
In practical application, the 8K switching station and the 4K switching station can work simultaneously, that is, the 8K video production and the 4K video production do not affect each other.
In some embodiments, the 8K switching station may perform following fabrication along with the output of the 4K switching station, and it is assumed that the 4K signal source outputs 32 paths of 4K signals, the 8K switching station has at least 9 paths of input interfaces, where 8 paths of 8K signals output by the 8K signal source are received, and 1 path of receiving linkage signals (also the 8K signals after up-conversion of the 4K signals) is illustrated, firstly, the 8K signal source inputs the 8 paths of 8K signals output by the 8K signal source to the 8K switching station via the 8K switch, and meanwhile, 8 paths of 4K signals (the 4K signals are SDI signals) with the same content but different resolutions output by the 8K signal source are input to the 4K switching station. In addition, the 32 paths of 4K signals output by the 4K signal source are sent to the 4K switching station, namely the 4K switching station receives 40 paths of 4K signals in total, the 4K switching station selects one path of the 4K signals to output according to the instruction, and if the output 4K signals are one of the 8 paths of 8K signals, the 8K switching station is controlled to output the 8K signals; if the output 4K signal does not correspond to the 8 paths of 8K signals, the output 4K signal is up-converted by an up-converter and then converted into an 8K signal (the 8K signal is a 4 paths of synchronous SDI signal), the up-converted 8K signal is subjected to format conversion by an IP converter and converted into an 8K signal in an IP format, and the converted signal is sent to a linkage signal interface of the 8K switching station through a switch, so that the 8K switching station outputs an 8K video signal received by the linkage signal interface. In the working mode, the function of the 8K switching table can be replaced by the 4K switching table, so that the 8K video can be output along with the 4K video at the same time, and an operator does not need to be arranged at the 8K switching table, thereby saving human resources.
Further, the application can also expand the production capability of 8K video through a 4K switching station. An example will be described in which the 8K switching station has 10 interfaces for 8K signals (signals in IP format) and the 4K switching station has 40 interfaces for 4K signals (signals in SDI format). In this operation mode, the signal interfaces of each 4 SDI formats of the 4K switching station are bound as a group to be processed and output, and this operation mode is described with the output of the 8K switching station as the main and the output of the 4K switching station as the two aspects.
As shown in fig. 4, which is a schematic diagram of a system structure mainly including the output of an 8K switching station, the 8K camera in fig. 4 is equivalent to an 8K signal source, and one 8K camera outputs one 8K signal; the 10 8K cameras transmit 10 8K signals to the IP converter 1, the IP converter 1 converts the received 10 8K signals into 4K signals of SDI format of 4 x 10 paths, and transmits the converted signals to the 4K switching station, the 4K switching station processes and outputs the 4K signals of 4 SDI format as a set of synchronization, outputs a set of 4K signals of 4 SDI format to the IP converter 2, and the IP converter 2 converts the set of 4K signals of 4 SDI format into 1 path 8K signals, and transmits to the 8K switching station via the 8K switch. The 9 8K cameras directly send the output 8K signals to the 8K switching station through the 8K switch, occupy 9 interfaces of the 8K switching station, and the 8K switching station processes 10 paths of 8K signals together with the converted 8K signals sent by the IP converter 2.
Fig. 5 is a schematic diagram of a system structure mainly based on the output of a 4K switching station, in which 10 8K cameras directly send 10 paths of 8K signals to the 8K switching station through an 8K switch, and occupy 10 interfaces; the 8K switching station sends one of the 10 paths of 8K signals to the IP converter through the 8K switch, the IP converter converts the 8K signals into a group of 4K signals in the 4-path SDI format, and sends the 4K signals to the 4K switching station; the 9 8K cameras send 9 8K video signals to the IP converter, and then the IP converter converts the 8K video signals into 4*9 paths of 4K signals (SDI signals) in SDI format to the 4K switching station, that is, the 4K switching station receives 4×9+4×1 paths of 4K signals, and the 4K switching station processes and outputs the 4K signals in the 4 SDI format as a set of synchronization signals and outputs a set of 4K signals in the 4 SDI format.
In the working mode of expanding the manufacturing capability of the 8K video through the 4K switching table, the 4K switching table and the 8K switching table work simultaneously, and the 4K switching table is used for grouping processing, so that 8K signals sent by 19 8K cameras can be processed simultaneously, and the number of the 8K video which can be manufactured is greatly improved. Specifically, the number of cameras is just an example, and in terms of logic, in this working mode, the 8K switching station has a interfaces, and the 4K switching station has 4B interfaces, so that this mode can process (b+a-1) 8K signals simultaneously.
