The detailed circuit of the data converter 424 is the same as that of the data converter 122 (as shown in fig. 3), and therefore, the detailed description thereof is omitted.
The number of data converters of fig. 5 is for illustration only and is not intended to limit the present invention. In other embodiments, the transmitting end 410 and the receiving end 420 may respectively include more than 3 data converters. The transmitting end 410 and the receiving end 420 have the same number of data converters.
FIG. 7 is a functional block diagram of a multimedia video and audio system according to another embodiment of the present invention. The transmitting end of the multimedia av system 700 includes a multimedia data generator 711, a data converter 712, a data converter 714, a data converter 716, and a data converter 718. The receiving end of the multimedia video and audio system 700 includes a data converter 722, a data converter 724, a data converter 726, and a data converter 728. The transmitting end and the receiving end are connected by a connection line 405.
In this embodiment, the multimedia data generator 711 generates super-high quality video content (e.g., frame rate (120 Hz), resolution 8Kx4K), and outputs the video content by averaging four paths, and the transmission protocols of the four paths are the same. In other words, the multimedia data P1-1, P1-2, P1-3, and P1-4 may be multimedia data transmitted by the V-by-One protocol at a frame rate of 120Hz and a resolution of 2Kx4K (i.e., the data amount (or resolution) of the multimedia data P1-1, P1-2, P1-3, and P1-4 is One fourth of the original AV content).
The data converter 718 encapsulates, encodes and/or converts the multimedia data P1-4 into multimedia data P2-1 (frame rate 120Hz, resolution 2Kx4K) in HDMI protocol or format. The internal circuit of the data converter 718 is shown in fig. 2 and will not be described in detail. The data converter 716 encapsulates, encodes and/or converts the multimedia data P1-3 and the multimedia data P2-1 into multimedia data P2-2 (frame rate 120Hz, resolution 4Kx4K) of HDMI protocol or format (i.e., the multimedia data P2-2 includes the multimedia data P1-3 and the multimedia data P2-1). The data converter 714 encapsulates, encodes and/or converts the multimedia data P1-2 and the multimedia data P2-2 into multimedia data P2-3 (frame rate 120Hz, resolution 6Kx4K) of HDMI protocol or format (i.e., the multimedia data P2-3 includes multimedia data P1-2 and multimedia data P2-2). The data converter 712 encapsulates, encodes and/or converts the multimedia data P1-1 and the multimedia data P2-3 into multimedia data P5 (frame rate 120Hz, resolution 8Kx4K) of HDMI protocol or format (i.e., the multimedia data P5 includes the multimedia data P1-1 and the multimedia data P2-3). The multimedia data P5 is transmitted to the receiving end through the connection line 405 in HDMI protocol or format. The internal circuits of the data converter 712, the data converter 714 and the data converter 716 are shown in fig. 5, and are not described again.
The data converter 722 receives the multimedia data P5 through the connection 405 and decapsulates, decodes and/or converts the multimedia data P5 to obtain multimedia data P1-1 and multimedia data P2-3. The data converter 724 decapsulates, decodes and/or converts the multimedia data P2-3 to obtain multimedia data P1-2 and multimedia data P2-2. The data converter 726 decapsulates, decodes and/or converts the multimedia data P2-2 to obtain multimedia data P1-3 and multimedia data P2-1. Finally, the data converter 724 decapsulates, decodes and/or converts the multimedia data P2-1 to obtain the multimedia data P1-4.
In the example of FIG. 7, although the multimedia data P1-1, the multimedia data P1-2, the multimedia data P1-3, and the multimedia data P1-4 are transmitted in 16 channels (i.e., the output interface of the multimedia data generator 711 includes 64 channels), only a single physical cable (i.e., the connection 405) is required between the transmitting end and the receiving end of the multimedia video and audio system 700. Compared to a similar configuration of the prior art, at least four physical cables (each comprising 16 channels) would be required to be connected between the data converters at the transmitting end and the receiving end. Therefore, the invention greatly simplifies the complexity of the data interface between the transmitting end and the receiving end of the multimedia audio-video system.
It is noted that although HDMI and USB-C include multiple channels, since the connectors of HDMI and USB-C are of a given hardware specification (as specified by the protocol), in general, all channels must be used together and not separately. In other words, the multiple channels of HDMI and USB-C are considered to be one-piece (i.e., a single cable for the user) in use. Moreover, since the HDMI and USB-C have bandwidths and/or data transmission rates greater than those of V-by-One, eDP, EPI, CEDS, and iSP protocols, a single HDMI cable or USB-C cable can be equivalent to multiple cables of V-by-One, eDP, EPI, CEDS, and iSP protocols in terms of transmission performance (i.e., bandwidth and/or data transmission rate). However, the present invention is not limited thereto, and the embodiment of the present invention can also implement the user-modified or derived transmission specification (for example, implemented by a specific packet transmission method or a channel control method) by using the hardware specification defined by HDMI and USB-C.
In summary, the present invention provides a technique for serially transmitting multimedia video data, in which multimedia video data originally transmitted via a plurality of physical connection lines or cables is transmitted via a single physical connection line or cable, so as to improve convenience, reduce assembly complexity, reduce interface volume, reduce cost, and improve product competitiveness.
In the drawings, the shapes, sizes and proportions of elements are merely illustrative, provided for a person of ordinary skill in the art to understand the invention, and are not intended to limit the invention.
Although the embodiments of the present invention have been described above, these embodiments are not intended to limit the present invention, and those skilled in the art can make variations on the technical features of the present invention according to the explicit or implicit contents of the present invention, and all such variations may fall within the scope of the patent protection sought by the present invention.
