Video streaming system with remote control capability

Abstract

This invention relates to a video streaming system with remote control capabilities, comprising at least one transmitting device connected to a video source device and at least one receiving device connected to a video display device. The transmitting device includes an HDMI interface, at least two USB interfaces, and a network interface. One of the at least two USB interfaces is used to connect to the video source device, while the other USB interfaces are used to directly connect to at least one input device. The system allows control of the directly connected transmitting or receiving device, or control of other transmitting or receiving devices via a network connection, thereby achieving remote control functionality.

4. The video streaming system with remote control function as described in claim 3, wherein the first HID control module uses USB OTG technology to convert the second control signal to simulate a physical input device directly connected to the video source device.

5. The video streaming system with remote control function as described in claim 1, wherein the receiving device comprises: A second HDMI port is provided for connecting to the image display device to send the image signal to the image display device; A second network interface for connecting to the network to receive the image signal or send the second control signal of the second input device; and a second USB interface for connecting the second input device, wherein the second input device can remotely control the image source device connected to the other transmitting device.

6. The video streaming system with remote control function as described in claim 5, wherein the receiving device further comprises: A second image processing module is connected to the second HDMI interface to convert the image signal into an image format; A second network transmission module, connected to the second network interface, for transmitting the image signal and the second control signal; a second streaming device detection module, connected to the second network transmission module, for scanning other receiving devices or transmitting devices connected to the same local area network; a second HID control module, connected to the second USB interface, for capturing the second control signal and encapsulating the second control signal into a packet; And a second image control module, which is connected to the second image processing module, the second network transmission module, the second streaming device exploration module and the second HID control module respectively, for selecting the image signal that the image display device wants to play.

7. The video streaming system with remote control functionality as described in claim 1, wherein the receiving device is configured to perform the following actions to achieve remote control: Action S1: The receiving device acquires the second control signal from the second input device via a second HID control module; Action S2: The second HID control module encapsulates the second control signal into a packet for network transmission and transmits the packet using the TCP protocol; Action S3: At least one transmitting device receives the packet via a first network transmission module and parses the packet via the first HID control module to obtain the second control signal; Action S4: The first HID control module of at least one transmitting device uses USB OTG technology to convert the second control signal to simulate the behavior of a USB HID device; and Action S5: The second control signal is used to control the video source device connected to at least one transmitting device.
