The ATSC3.0 standard is a new generation terrestrial digital tv broadcasting system in the united states, and the ATSC3.0 standard is a layered structure defining standards of each layer of a physical layer, a transport layer, an application layer, and a security layer, respectively. ATSC3.0 is currently the most advanced digital tv broadcasting system, and will be widely used in the countries of the united states, korea, canada, etc., particularly in the countries and regions of north america in the future.
The ATSC3.0 describes a format conversion process of the ALP in the Link layer Protocol a330, where the ALP is a short term for ATSC Link-layer Protocol, and encapsulates different types of input data into a uniform ALP format, where the ALP packet length is not fixed, and then transmits the ALP packet to the physical layer for channel coding and modulation output. For an ATSC3.0 receiving end, a radio frequency signal of ATSC3.0 is converted into a low-intermediate frequency signal through a high-frequency head, then channel demodulation and channel decoding are carried out through a demod chip, and then demod outputs ALP data to demux of an SOC for processing.
As shown in fig. 1 and fig. 2, the current processing method is that Demod outputs ALP data, which is first converted into a TS Stream (Transport Stream) of 188 bytes fixed length, the Transport Stream having a fixed packet length of 188 bytes, which is a data Stream defined according to ITU-T rec.h.222.0| ISO/IEC 13818-2 and ISO/IEC13818-3 protocols to prevent one or more channels of encoded data from being transmitted and stored when serious errors may occur, and then adds 0x47 header code to encapsulate and output the data according to the TS Stream. Then the SOC receiving end receives the TS stream, then the head code of the TS stream is removed, and the TS stream is spliced and converted into ALP packet encapsulated data through a software algorithm. Therefore, the method not only occupies a lot of resources of a CPU and influences the system operation efficiency, but also easily makes mistakes in the software splicing process due to the fact that the ALP has no verification mechanism, and thus a picture has mosaic.
In order to solve the above problem, in an embodiment of the present application, an ALP data packet sent by a demodulator is received, where the ALP data packet includes a number of data segments; each time a data segment of an ALP packet is received, the data segment is processed. The invention directly carries out full-flow output on the ALP data packet with variable length through the demodulator without carrying out TS flow encapsulation conversion by a decoder and a process of recovering the ALP packet by TS flow assembled by the SOC chip, thereby improving the system operation efficiency, improving the reliability of ALP data and reducing the occupation of system operation resources.
The invention will be further explained by the description of the embodiments with reference to the drawings.
The embodiment provides a method for processing an ALP packet, as shown in fig. 3, the method includes:
s100, receiving an ALP data packet sent by a demodulator, wherein the ALP data packet comprises a plurality of data segments.
In this embodiment, the output of the demodulator ALP packet is output according to the full variable-length ALP stream, and the processing method of the ALP packet is based on the ALP packet processing system, as shown in fig. 4, which is composed of Tuner (for down-converting ATSC3.0 radio frequency signal from high frequency signal to low intermediate frequency signal, Demod (for down-converting Demod) and SOC chip, and then Tuner outputs IF signal to Demod.
Further, the function of Demod is to channel demodulate and channel decode the ATSC3.0 signal, yielding an ALP signal. The ALP signals output by the Demod comprise ALP data, valid, clk and sync, and in practical application, the ALP is divided into parallel data and serial data, if the ALP is the parallel data, 8 data signal lines are provided, and if the ALP is the serial data, only 1 data signal line is provided. Demod is capable of having two output modes, wherein one mode is the original ALP full stream data output, and the data length is variable; another mode is to convert into 188 bytes long TS stream packet output. In this embodiment, Demod needs to output the first mode, for example, fig. 5 is a schematic diagram of full stream output and reception of ALP data packets provided by the present invention.
Further, the SOC chip includes a CPU (central processing unit), a buffer, and a Demux (demultiplexer) therein. In this embodiment, the SOC chip receives the ALP packet transmitted by the demodulator full stream. Thus, full-stream output and reception of ALP can be realized without converting into TS packets by the above method. Therefore, the invention avoids the complex process of firstly converting TS stream and then splicing and restoring ALP by ALP full stream output and reception, thereby improving the transmission efficiency and reliability of ALP, reducing the occupied system operation resources and improving the operation efficiency of the system.
In practical application, the ALP data packet sent by the receiving demodulator is specifically: receiving ALP data packets sent by the demodulator full stream, and storing the ALP data packets in a buffer area, so that a CPU transfers a complete ALP data packet (data segment) extracted in the subsequent step to a Demux for processing.
S200, whenever a data segment of an ALP packet is received, processing the data segment.
Specifically, as shown in fig. 6, fig. 6 is a waveform diagram of ALP output from the demodulator according to the present invention. As can be seen from fig. 6, the ALPCLK signal is a reference clock for acquiring the ALPDATA, that is, a signal acquiring the ALPDATA when the ALPCLK rises; the ALPFALLID signal is high to represent valid data of ALPFATA, and low to represent invalid data; the ALPSYNC signal represents synchronization data for each ALP packet, wherein the ALPDATA data aligned with the rising edge of the ALPSYNC signal is the header, i.e., the first data bit, of the ALP packet. Correspondingly, each time a data segment of an ALP packet is received, the method specifically includes:
s201, determining a head code and an end packet of the ALP data packet;
in this embodiment, a complete ALP data packet (data segment) may be determined according to a header code and an end packet of an ALP data packet output by a full stream, and correspondingly, the determining of the header code and the end packet of the ALP data packet specifically includes:
s2011, identifying and marking the head code of the ALP data packet through a sync signal;
s2012, identifying an end packet of the ALP data packet by a valid signal.
Specifically, the header code for identifying and identifying the ALP data packet through the sync signal is specifically: when the sync signal is detected to be changed from low level to high level, identifying the 1 st data bit of the ALP data packet, and adding preset data to the 1 st data bit; taking the preset data as a head code; the identifying the end packet of the ALP data packet by the valid signal specifically includes: when it is detected that the valid signal is changed from the high level to the low level, an end packet of the ALP data packet is determined. In this embodiment, the valid signal line and the sync signal line of the ALP are simultaneously connected to two GPIOs of the CPU, and certainly, in practical applications, the valid signal line and the sync signal line of the ALP are also simultaneously connected to the same GPIO of the CPU.
S202, extracting data between the head code and the end packet, and using the data as a data segment.
Specifically, when the ALPDATA of Demod enters the buffer, and when the CPU detects that the sync signal of the ALP of the GPIO2 changes from low level to high level, it recognizes that the corresponding ALP data at this time is the 1 st data bit, and adds a specific data bit as a header, for example, the header is 0 xAA; then when the CPU detects that the valid signal of the ALP of the GPIO1 changes from high level to low level, the CPU recognizes that the ALP data packet is finished and a complete ALP data packet is buffered in the buffer, and then the CPU transfers the complete ALP data packet of the buffer to the Demux for processing. By analogy, the next ALP packet is received. Full stream output and reception of ALP can be realized without being converted into TS stream by the above method. Therefore, by outputting and receiving the full stream of the ALP, the complex processes of firstly converting TS stream and splicing and restoring the ALP in the original method are avoided, so that the transmission efficiency and the reliability of the ALP are improved, the occupied system operation resources are reduced, and the system operation efficiency is improved.
In practical applications, each time a data segment of an ALP packet is received, processing the data segment further includes: and emptying the data stored in the buffer area. Thus, when the 1 st data bit received next by the buffer is the head code of the next complete ALP data packet, the next complete ALP data packet can be conveniently and accurately acquired, and then the packet is transmitted to the Demux for processing.
In summary, the present invention discloses a method for processing an ALP packet, where the method includes: receiving an ALP data packet sent by a demodulator, wherein the ALP data packet comprises a plurality of data segments; each time a data segment of an ALP packet is received, the data segment is processed. The invention directly carries out full-flow output on the ALP data packet with variable length through the demodulator without carrying out TS flow encapsulation conversion by a decoder and a process of recovering the ALP packet by TS flow assembled by the SOC chip, thereby improving the system operation efficiency, improving the reliability of ALP data and reducing the occupation of system operation resources.
