Description

Technical Field

[0001] This utility model relates to the field of digital cinema projection technology, and in particular to a cinema playback controller. Background Technology

[0002] The application of LED cinema playback controllers is becoming increasingly widespread, and different applications often have different requirements. For example, some movie sources only require a resolution of 4K@30Hz to play, while others require a resolution of 4K@120Hz. Furthermore, cinema equipment manufacturers will compare cinema playback servers (IMBs) from different manufacturers to select the one with the best cost-performance ratio.

[0003] With the widespread adoption of digital cinema LED projection technology, cinema equipment needs to be compatible with IMBs of different resolutions and interface specifications. Existing LED cinema playback controllers' capture cards only support a single interface (such as PCIe or Molex), preventing cinemas from flexibly selecting the most cost-effective IMB equipment. For example, IMBs from manufacturer A transmit LVDS signals via a PCIe interface, while IMBs from manufacturer B transmit SERDES signals via a Molex interface. These differences in interface physical form and signal protocol make existing capture cards incompatible. Therefore, a cinema capture card supporting multiple interfaces is urgently needed to improve equipment compatibility. Utility Model Content

[0004] Therefore, it is necessary to provide a movie playback controller that can support movie playback servers from different manufacturers to address the aforementioned technical problems.

[0005] This utility model provides a movie playback controller, including a main control module, a video access module, a video output module, and an interface module; the interface module is connected to the main control module, the main control module processes the signals from the manufacturer's server transmitted by the interface module and the signals from the video access module, and then outputs them to the video output module, which outputs the final video signal.

[0006] In some embodiments, the interface module includes at least two interface circuits.

[0007] In some embodiments, the interface circuitry includes a PCIe interface circuitry and a Molex interface circuitry.

[0008] In some embodiments, the PCIe interface circuit transmits data via the LVDS signal protocol, and the Molex interface circuit transmits data via the SERDES signal protocol.

[0009] In some embodiments, the main control module includes a signal conversion unit that converts the signals from the interface module into a unified video output format.

[0010] In some embodiments, the video output module further includes a sending card.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Unlike the prior art, the movie playback controller provided by this utility model can connect to multiple interface circuits in the interface module. After the main control circuit processes the input signal, it transmits it to the LED display screen through the video output circuit, which solves the incompatibility problem of IMB interfaces from different manufacturers and reduces the procurement cost of cinema equipment; it supports multiple resolutions from 4K@30Hz to 4K@120Hz, adapting to diverse projection needs.

[0017] Please see Figure 1 One embodiment of this utility model provides a movie playback controller 100, including a main control module 110, a video access module 120, a video output module 130, and an interface module 140; the interface module 140 is connected to the main control module 110, the main control module 110 processes the signals from the manufacturer's server transmitted by the interface module 140 and the signals from the video access module 120, and then outputs them to the video output module 130, which outputs the final video signal.

[0018] In a specific embodiment, the interface module 140 includes at least two interface circuits; the interface circuits include a PCIe interface circuit and a Molex interface circuit; the PCIe interface circuit transmits data via the LVDS signal protocol, and the Molex interface circuit transmits data via the SERDES signal protocol; the main control module package 110 includes a signal conversion unit 111, which converts the signals of the interface module 140 into a unified video output format; the video output module 130 further includes a sending card 131.

[0019] The specific process is as follows: The PCIe interface circuit of the cinema playback controller receives the 4K@120Hz video signal from IMB (Manufacturer A) via the LVDS protocol, while the Molex interface circuit receives the 4K@60Hz signal from IMB (Manufacturer B) via the SERDES protocol. After decoding and format conversion of the input signals, the main control circuit outputs them to the LED display screen via the sending card.
