Detailed Description
In order that those skilled in the art will better understand the present disclosure, a technical solution in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the described embodiments of the disclosure may be capable of operation in sequences other than those illustrated or described herein.
Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules is not necessarily limited to those steps or modules that are expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. In order to better understand the present disclosure, a method, an apparatus, an electronic device, and a storage medium for transmitting vehicle-mounted video data provided by embodiments of the present disclosure are described in detail below with reference to fig. 1 to 6.
Please refer to fig. 1, which is a flowchart of a vehicle-mounted video data transmission method according to an embodiment of the present disclosure, the method specifically includes the following steps:
s101, receiving the complete line effective data transmitted through oLDI interfaces, wherein the end of the complete line effective data is inserted with a first transmission detection code.
Exemplary, as shown in fig. 2, a schematic diagram of a data format of an in-vehicle video signal according to an embodiment of the disclosure is provided. As can be seen from the figure, the signals to be transmitted include timing control signal video clock (DCK), vertical Sync (VSYNC), horizontal Sync (HSYNC), data ENABLE (ENABLE), and 24-bit video data signal DB [23:0], in which three components of RGB, red, green and blue each occupy 8 bits. Where VLW (Vertical low width, also referred to as VERTICAL SYNC WIDTH) represents the vertical sync signal width, VBP (video back porch) represents the vertical trailing edge, VACT (video active) represents video activation, HLW (horizontal low width, also referred to as horizontal SYNC WIDTH) represents the horizontal sync signal width, HBP (horizontal back porch) represents the horizontal trailing edge, HACT (horizontal video active) represents horizontal video activation, VSYNC represents the start of a frame, HSYNC represents the start of a row, and ENABLE represents valid data in a row.
Further, in addition to the video clock signal, a total of 27 bit signals are required to transmit video, i.e., RGB data occupies 24 bits, vsync, HSYNC, and ENABLE each occupies 1bit, and valid data only appears in a valid data area, i.e., HACT area in the figure. As shown in fig. 3, which is a schematic diagram of a transmission mapping format of a vehicle-mounted video signal provided by an embodiment of the present disclosure, the oLDI interface (i.e., open LVDSDISPLAY INTERFACE, also translated into OpenLDI) is mapped onto 5-path LVDS (Low Voltage DIFFERENTIAL SIGNALING, low Voltage differential signal) according to the format of the diagram when the video signal is transmitted, wherein 27-bit video signals except for the video clock signal are mapped onto 4-path LVDS such as d0+/-, d1+/-, D2+/-, D3+/-, RO0 represents bit0 of the Red component, RO1 represents bit1 of the Red component, GO0 represents bit0 of the Green component, BO0 represents bit0 of the Blue component, and so on.
Further, since the use of data in the horizontal front tip region (horizontal front porch) is not described in the oLDI standard, the embodiments of the present disclosure insert the 16-bit first transmission detection code after the end of the valid data in the horizontal direction, i.e., in the first clock cycle of the horizontal front tip region, without adding an additional interface signal or changing the data structure of the existing code stream.
S102, calculating a second transmission detection code corresponding to the effective data of the complete line.
Illustratively, the first transmission detection code and the second transmission detection code in the embodiments of the present disclosure may include a cyclic redundancy check code (Cyclic Redundancy Check, CRC) or an Error CHECKING AND Correcting Error Correction Code (ECC), that is, the first transmission detection code and the second transmission detection code are both cyclic redundancy check codes, or the first transmission detection code and the second transmission detection code are both Error correction codes.
Further, the principle of cyclic redundancy check codes agrees with a generator polynomial for the receiver and the sender, which generator polynomial is usually a binary number and remains unchanged throughout the transmission. The generator polynomial is used at the sender (e.g., serializer) to modulo 2 the information polynomial to generate a check code, and the received code polynomial is used at the receiver (e.g., deserializer) to modulo 2 the generator polynomial to detect and determine the error location. And the error checking error correcting code is based on the principle that an extra bit of data stores a code encrypted by data, when the data is written into the memory, the corresponding ECC code is also saved, when the data stored just is read back again, the saved ECC code is compared with the ECC code generated when the data is read, and if the two codes are different, the two codes are decoded to determine which bit of the data is wrong.
S103, comparing the second transmission detection code with the first transmission detection code, determining that the current data transmission is correct when the second transmission detection code is the same as the first transmission detection code, and determining that the current data transmission is wrong when the second transmission detection code is different from the first transmission detection code.
For example, when the second transmission detection code is different from the first transmission detection code, after determining that the current line data is transmitted with errors, the embodiment of the disclosure may discard the current line data and timely report an error interrupt to the master. Further, in the case that both the first transmission detection code and the second transmission detection code are error checking error correcting codes, the embodiment of the disclosure can also correct the 1-bit error detected by the current data, and the set advantage is that diversified use requirements can be met, and the application scene is wide.
According to the vehicle-mounted video data transmission method provided by the embodiment of the disclosure, the first transmission detection code is inserted into the tail end of the effective data of the complete line transmitted by the oLDI interface, namely, the tail end is located in the horizontal front tip area in the oLDI standard, no additional interface signal is needed or the data structure of the existing code stream is changed, further, the second transmission detection code corresponding to the effective data of the complete line is calculated, the second transmission detection code is compared with the first transmission detection code, when the second transmission detection code is identical with the first transmission detection code, the correct transmission of the current line is determined, and when the second transmission detection code is different from the first transmission detection code, the error of the transmission of the current line is determined, so that the detection efficiency and the accuracy are greatly improved, the compatibility is strong, and the vehicle-mounted video data transmission method can be widely applied to various scenes.
Based on the foregoing embodiments, the present disclosure provides an in-vehicle video data transmission apparatus. The in-vehicle video data transmission device 100 can be applied to the in-vehicle video data transmission method according to the corresponding embodiment of fig. 1 to 3. Referring to fig. 4, the vehicle-mounted video data transmission apparatus 100 includes:

Optionally, in some embodiments of the present disclosure the first transmission detection code and the second transmission detection code comprise cyclic redundancy check codes or error checking error correction codes.
