Fig. 1 is a block diagram of a playing system according to an embodiment of the present invention. The playing system may include a player 10, a signal transmission device 20 and a display 30. The player 10 is a signal source of the playing system for providing at least one signal to be played. In an embodiment of the present invention, the signal may be an image signal, an audio signal, or a video signal. For simplicity, the following paragraphs are representative of video signals. The player 10 may be, for example and without limitation, a mobile device such as a mobile phone or a tablet computer, a computer device such as a notebook computer or a desktop computer, a set-top box (abbreviated STB), a Compact Disc (abbreviated CD)/Digital Versatile Disc (abbreviated DVD) player, or other devices that can provide an image, audio, or video signal. The display 30 may be, for example, but not limited to, a display panel, a screen, or a digital television for displaying the video signal.
The signal transmission device 20 is a pluggable or removable physical device coupled between the player 10 and the display 30 for transmitting at least one video signal between the player 10 and the display 30. When the signal transmission device 20 is coupled between the player 10 and the display 30, a signal to be played can be transmitted from the player 10 to the display 30 through the signal transmission device 20, and the signal transmission device 20 can optionally perform appropriate processing on the signal before the signal is provided to the display 30, so as to improve signal resolution and/or enhance signal quality (as will be described in more detail in the following paragraphs).
It should be noted that fig. 1 is a simplified block diagram of a playback system, in which the signal transmission device 20 is shown by a line. The signal transmission device 20 of the present invention is not limited to the shape shown in the drawings. In embodiments of the present invention, the signal transmission device 20 may be implemented as a number of different products. Depending on the type of product being realized, the signal transmission means 20 may have a corresponding shape. For example, the signal transmission device 20 may be implemented as a connection device (dongle), a cable (cable), an adaptor (adapter) or the like, and thus, the signal transmission device 20 may actually include one or more of a connector or plug for connecting the player 10 and the display 30, and a cable or transmission line for transmitting a video signal. Furthermore, it is noted that fig. 1 only shows components relevant to the present invention. Those skilled in the art will appreciate that the playback system may include many components not shown in fig. 1 to perform the functions of displaying or playing back images, audio or video signals, etc.
In an embodiment of the present invention, the signal transmission device 20 may include at least one signal processing device (e.g., the signal processing device 200 described below) in order to perform appropriate processing on the signal. The signal processing device may include a receiver, a signal processor, and a transmitter. The receiver is used for receiving a video signal (e.g., a first video signal) provided by the player 10. The signal processor is coupled to the receiver for detecting an image format or an image resolution of the first video signal and processing the first video signal according to the image format or the image resolution of the first video signal to generate a second video signal, wherein the image format of the second video signal may be different from the image format of the first video signal and/or the image resolution of the second video signal may be different from the image resolution of the first video signal. The transmitter is used for outputting the second video signal, so that the second video signal can be provided to the display 30.
Fig. 2 is a block diagram of an exemplary signal processing apparatus according to an embodiment of the invention. The signal processing apparatus 200 may include a plurality of functional blocks, each of which is configured to perform corresponding signal processing. The functional blocks can be implemented by corresponding hardware circuits respectively and integrated into a signal processor. The functional blocks can also be implemented by a microprocessor executing corresponding software or firmware, and the microprocessor becomes a signal processor included in the signal processing apparatus 200 when executing corresponding software/firmware. In addition, the above-mentioned functional blocks can be implemented in combination.
The signal processing device 200 may include one or more receivers, such as receivers 201 and 202. When the signal processing apparatus 200 includes a plurality of receivers, each receiver is configured to receive and transmit signals transmitted according to different transmission interface standards. For example, in one embodiment of the present invention, the receiver 201 may be a Universal Serial Bus (USB) receiver. The receiver 202 may be a High Definition Multimedia Interface (HDMI) receiver. When the player 10 is a product with a USB interface, the receiver 201 can receive a video signal to be played by the player 10 through the USB interface. Similarly, when the player 10 is a product with an HDMI interface, the receiver 202 can receive a video signal to be played by the player 10 through the HDMI interface.
The signal processing apparatus 200 may further include a video/audio signal decoder 203, an image capturing device 204 and an audio processor 205. The video/audio signal decoder 203 is used to decode the received video signal or audio signal into a given format when needed. The image extractor 204 extracts image data from the video signal. The audio processor 205 extracts audio data from the video signal and processes the audio signal according to an audio format, for example, performs audio signal processing on the audio data, wherein the audio signal processing may be, for example and without limitation, noise removal, signal purification, signal amplification, and the like.
In addition, the signal processing apparatus 200 may further include an image resolution detector 206, an image scaler 207, and an image processor 208. The image resolution detector 206 is used to detect the image resolution. For example, the image resolution detector 206 may know the image resolution by analyzing the header (header) content of the image data, or by analyzing the communication signal transmitted between the player 10 and the display 30. The image scaler 207 is to scale an image. For example, the image scaler 207 may adjust the size and/or resolution of the image according to the current image resolution, for example, perform a dot filling operation by using an image interpolation method to increase the resolution of the output image. The image processor 208 is configured to perform corresponding processing, such as but not limited to edge sharpening, denoising, contrast enhancement, smoothing, etc., according to the current image format and image resolution, so as to further improve the image quality.
The signal processing apparatus 200 may further include an image audio wrapper 209, a transmitter 210, and a power delivery controller 211. The image audio wrapper 209 is used to wrap the processed audio data and image data into a video signal. The transmitter 210 is configured to output an image audio signal. The power transfer controller 211 is used for retrieving power from a coupled peripheral device (e.g., the player 10 or the display 30) and providing the power to the internal components (coupling relationship is not shown) of the signal processing apparatus 200 to enable operation thereof.
According to the first embodiment of the present invention, the signal transmission device 20 can be implemented to be included in a connection device (dongle). Fig. 3 is a schematic diagram of a product connecting device according to an embodiment of the invention. The connection device 300 may include the signal processing device and a plurality of connectors, such as a first connector for coupling with a player (e.g., the player 10 of fig. 1) and a second connector for coupling with a display (e.g., the display 30 of fig. 1), wherein the connectors may also be a plug or a socket. In the embodiment of the present invention, when the signal transmission device 20 is implemented as being included in a connection device (e.g., the connection device 300), the signal transmission device 20 can be connected to one of the player or the display through a connector of the connection device 300, and connected to a cable (not shown) or a transmission line through another connector of the connection device 300, and then connected to the other of the player or the display through the cable or the transmission line.
Fig. 4 is a block diagram of a playback system according to a first embodiment of the present invention, which shows a possible implementation manner of a signal transmission device (e.g., the signal transmission device 20 of fig. 1). In this embodiment, the signal transmission device is implemented as the connection device 400 or is implemented in the connection device 400. One end of the connection device 400 is coupled to the display 450, for example, by connecting with a connector or plugging into a port (port) of the display 450, and the other end of the connection device 400 is coupled to a USB cable 440 and is coupled to the player 460 through the USB cable 440. That is, in this embodiment, the signal transmission device including the signal processing device is only one component disposed on a signal transmission path between the player and the display, and the signal transmission path may further include a cable coupled to the player. It is noted that fig. 4 shows only one of the various embodiments of the present invention. Thus, the present invention is not limited to the embodiment shown in fig. 4. For example, the connection device 400 can also be designed as a device that is plugged into or coupled to the player, i.e., one end of the connection device 400 is coupled to the player 460, and the other end is coupled to the display 450 through a cable or transmission line.
The connection device 400 may include a signal processing device 410, a USB connector 420 and an HDMI connector 430. The signal processing device 410 may include a receiver 411, a transmitter 412, a signal processor 413 and a power delivery controller 414. In this embodiment, the receiver 411 may be a USB functional block, and the transmitter 412 may be an HDMI transmitter. The receiver 411 may be coupled to the USB connector 420, and the signal processing device 410 receives the video signal (e.g., the first video signal) output by the player 460 through the USB connector 420 and the USB cable 440 outside the connection device 400. The transmitter 412 may be coupled to the HDMI connector 430, and the video signal (e.g., the second video signal) processed by the signal processing device 410 may be provided to the display 450 through the HDMI connector 430.
The signal processor 413 may be a combination formed by a plurality of functional blocks in fig. 2. For example, depending on the signal processing function requirement of the product, a part of the functional blocks in fig. 2 may be selected to implement the signal processor 413. According to an embodiment of the present invention, the signal processor 413 may detect an image format or an image resolution of the first video signal, and process the first video signal according to the image format or the image resolution to generate the second video signal. The image format of the second video signal may be different from the image format of the first video signal, e.g., the image format of the second video signal may be converted to a higher-order image format supported by the display 450, or the image resolution of the second video signal may be higher than the image resolution of the first video signal.
In addition, in an embodiment of the invention, the signal processor 413 may further detect a target image resolution supported by the display 450, for example, the target image resolution supported by the display 450 or the target image resolution of an image desired to be received by the display 450 is known by analyzing a communication signal transmitted between the player 460 and the display 450, and when the image resolution of the first video signal is different from or does not reach the target image resolution, the signal processor 413 may process the first video signal according to the target image resolution to generate the second video signal, so that the image resolution of the second video signal is equal to the target image resolution.
In addition, the signal processor 413 can also process the audio data of the first video signal and package the processed audio data and the processed image data into the second video signal, so that the audio quality of the second video signal can also be improved.
The power delivery controller 414 may retrieve power from the player 460 through the USB connector 420 and provide the power to the internal components of the signal processing device 410 for operation. For example, the single-headed arrows in fig. 4 show the processing and transmission directions of the video signals, and each of the double-headed arrows represents the direction of the control signals and the power signals transmitted between the power transmission controller 414 and the peripheral USB device.
It should be noted that, in an embodiment of the present invention, when the image resolution of the first video signal has reached the target image resolution, or the image/audio quality of the first video signal has reached the level required by the display 450, the signal processor 413 may also directly output the first video signal as the second video signal without performing additional signal processing on the first video signal.
In addition, in another embodiment of the present invention, when the image resolution of the first video signal has reached the target image resolution, or the image/audio quality of the first video signal has already reached the level required by the display 450, the signal processor 413 may further perform additional signal processing on the first video signal to generate a second video signal with better quality, in order to further improve the signal quality.
In addition, in another embodiment of the present invention, if the player 460 has previously increased the image resolution of the first video signal according to the target image resolution, the signal processor 413 may also restore the image resolution of the first video signal to the original image resolution, and then perform image amplification and other optimization processes on the restored signal again to generate the second video signal with better quality.
