A first embodiment of the present invention provides a digital television software upgrading method, and referring to fig. 2, fig. 2 is a schematic flow diagram of the first embodiment of the digital television software upgrading method of the present invention, where the digital television software upgrading method includes:
step S100, when the digital television terminal is started, determining whether the code stream information contains upgrading information;
the greatest difference from the software upgrading by using the network is that the method of the invention automatically searches the upgrading information in the broadcast television signal when the digital television terminal is started every time, and the network upgrading is inquired in the network when the digital television terminal is started every time.
Generally, the digital television service is implemented by digitally compressing, encoding and modulating captured analog signals such as video and audio to form digital signals, transmitting the digital signals through satellite, terrestrial radio or cable, receiving the digital signals by a digital television terminal, and restoring the analog signals such as video and audio through digital demodulation and decoding processing to display and play. The program source received by the digital television terminal or the set-top box is transmitted in the form of multi-segment code stream, and common systems include DVB-T, ATSC, ISDB and the like. The DVB standard adopted in China at present is a digital television standard adopted in European countries, the base band data format adopts an MPEG-2 standard, namely video and audio coding and code stream multiplexing conform to the MPEG-2 standard, and a Moving Picture experts Group (MPEG-2) is established in 1988 as an international standard related to Moving Picture compression. Among them, the MPEG-2TS Stream is one of MPEG-2 format types, which is called MPEG-2Transport Stream in its entirety, and has become a commonly used system layer coding standard in the field of digital tv. The TS transport stream can combine multiple programs into one stream for transmission with certain error code channels, which allows the same program to contain multiple audio and video streams, and can also add some additional information. It features that any segment in video stream can be decoded independently, and is suitable for transmitting real-time broadcast TV program. The TS code stream adopts a packet structure with fixed length, and when the synchronous information of a certain TS packet is damaged, the receiver can detect the synchronous information in the bread behind the TS packet at a fixed position, so that the synchronization is recovered, and the information loss is avoided.
The TS stream is a bit stream format based on packets, each of which is composed of a Packet Header (Packet Header) and Packet Data (Packet Data). Where the packet header indicates the packet's attributes and gives the packet data its unique network identifier PID. The PID is a unique identifier of each packet data in the current TS stream, and the type of the packet data can be known by reading the packet header of each packet. Each packet is 188 bytes or 204 bytes, the packet structure of 204 bytes is that 16 bytes of CRC check data are added after 188 bytes, and other formats are the same.
In this embodiment, when software upgrade needs to be performed on a digital television, for example, a television vendor has a new function update or needs to repair a small problem existing in a machine, the television vendor provides the latest version of the upgrade software to a television program service provider, where the television program service provider refers to a television station or the like with relevant qualification.

The failure of the digital television terminal to identify the upgrade software is usually an error in the verification process, so that the CRC + file for verification needs to be identified again and the upgrade software needs to be received again.
In the digital television software upgrading method provided in the embodiment, when the upgrading information in the code stream information is detected, the upgrading software corresponding to the upgrading information is identified; then, when the upgrade software is successfully identified, restoring the upgrade software into upgrade source software, and storing the upgrade source software into the digital television terminal; the corresponding upgrading software is identified according to the upgrading information in the code stream information, so that the accuracy of file transmission and related data can be ensured, and the cost of the whole upgrading software transmission program can be effectively reduced due to the low cost of the method.
Based on the third embodiment, a fourth embodiment of the digital television software upgrading method of the present invention is proposed, and referring to fig. 7, step S210 includes:
step S211, identifying a verification file based on the upgrading information;
the HW and SW information is carried in the process of compiling the digital television upgrading software, then the upgrading software with the HW and SW information is converted into a TS code stream format through a related tool, when the TS code stream containing the upgrading software is transmitted to a target digital television terminal, the digital television terminal can be the code stream containing the upgrading software according to the information because the HW and SW information is contained in the data information. When the digital television terminal identifies the upgrade information, the CRC + check file in the code stream to which the upgrade file belongs can be further identified.
In the field of data storage and data communication, error detection means has to be adopted to ensure the correctness of data. Among many error detection measures, CRC is the most well-known one. The CRC is called as cyclic redundancy check, and is characterized in that: the error detection capability is extremely strong, the cost is low, and the method is easy to realize by using an encoder and a detection circuit. From the viewpoint of the error detection capability, the error which cannot be found by the method is only below 0.0047 percent. The method is far superior to parity check, arithmetic and check and the like in terms of performance and overhead. Thus, CRC is ubiquitous in the fields of data storage and data communication.
And step S212, when the identification of the check file is finished, checking the corresponding digital television upgrading software in a mode of identifying the CRC file.
The preset mode is a specific mode for checking the digital television upgrade software by using a CRC (cyclic redundancy check) technology, and can be set by a digital television upgrade software developer, under a normal condition, the digital television upgrade software developer can check by using a remainder of modulo-2 division, and the adopted divisors are different, and the types of CRC are also different. Typically, the divisor of a CRC is represented by a generator polynomial. The cyclic redundancy code CRC can be obtained by using a predetermined generator polynomial g (x) when encoding is performed at a transmitting end and checking is performed at a receiving end, where k bits of information to be transmitted may correspond to a (k-1) th-order polynomial k (x), r bits of redundancy bits correspond to a (r-1) th-order polynomial r (x), and a codeword of n ═ k + r, which is formed by adding r bits of redundancy bits to the k bits of information, corresponds to a (n-1) th-order polynomial. That is, a cyclic redundancy code is generated at the transmitting end and is transmitted to the receiving end together with the information bits. The check process of the receiving end is to divide the received code word polynomial by G (X), if the residue is zero, the transmission is considered to be error-free; if the remainder is not zero, the transmission has errors.
In the digital television software upgrading method provided in the embodiment, the verification file is identified based on the upgrading information; then, when the verification file is identified, verifying the corresponding digital television upgrading software according to a preset mode; the mode of checking the upgrade software by using the CRC + file can effectively improve the accuracy of data transmission, has low cost, reduces errors in the transmission process, and improves the use experience of users.

And when the WEB receives a data transmission request sent by the digital television terminal, the operation data information of the digital television terminal is obtained through the shell script. Input-output redirection in the Linux Shell environment is represented by a sum symbol, and 0, 1 and 2 represent a standard input, a standard output and a standard error output, respectively.
When a digital television terminal sends a data transmission request, 3 parameters are required to be transmitted to a WEB terminal, wherein the parameters comprise a project ID number, a host IP number and the output time of each row of logs; the transmission item ID number is used for judging which item the digital television terminal belongs to, the transmission host IP number is used for judging which IP of the item the terminal belongs to, so that the problem of which television in the user home is located, and the output time of each row of log is transmitted, so that the analysis and research of the log by developers are facilitated.
