The invention will be further described by the description of embodiments with reference to the accompanying drawings.
The present embodiment provides a method for filtering TLV data packets, as shown in fig. 1, where the method includes:
and S100, when receiving the TLV data packet, judging the payload type corresponding to the TLV data packet.
Specifically, in the japanese ISDB S3 digital television broadcasting system, full-stream data of TLV packets is transferred from the kernel layer to the user layer, where a large amount of unnecessary data is contained and discarded after parsing, but the data to be discarded is also copied to the user layer, and this process results in high system bandwidth occupation, so that the CPU occupancy rate is too high, and the smoothness of the system is reduced. By acquiring the TLV data packets output by the full stream and processing each received TLV data packet respectively, the invention can obviously reduce the data copy from the kernel to the user layer, further reduce CPU Loading and system bus occupation and improve the system fluency.
In this embodiment, when receiving a TLV data packet, the payload type corresponding to the TLV data packet is first determined, and when the payload type is a preset payload type, the TLV data packet is filtered. Correspondingly, the judging the payload type corresponding to the TLV data packet specifically includes:
s10, acquiring a character string of a packet head designated area of the TLV data packet;
s20, judging the payload type corresponding to the TLV data packet according to the character string.
Specifically, the packet header designated area is the second byte of the packet header, and in practical application, as shown in fig. 2, fig. 2 is a schematic format diagram of the media transport packet provided in the present invention. The packet header is a packet header of a media transmission packet corresponding to a TLV data packet, and the character string for acquiring the packet header designated area of the TLV data packet specifically comprises: and analyzing the second byte of the packet header of the TLV data packet to obtain a character string. In this embodiment, the payload type of the TLV packet may be obtained by determining the lower 6 bits of the second byte of the packet header. For example, when the second byte is 0x00, the payload type corresponding to the TLV packet is an MPU type (media playing unit); when the second byte is 0x01, the payload type corresponding to the TLV packet is the signaling message type.
Correspondingly, in practical application, the judging, according to the character string, the payload type corresponding to the TLV packet specifically includes:
s21, comparing the character string with a preset character string;
s22, when the character string is the same as a preset character string, the payload type corresponding to the TLV data packet is a preset payload type.
Specifically, the preset character string is Ox00, and the preset payload type is MPU type, that is, when the character string is the same as the preset character string, that is, the parsed character string is 0x00, the payload type corresponding to the TLV packet is MPU type. It should be noted that, except the TLV-SI data and the NTP packet, other data have the header of the media transmission packet, i.e. the MMTP header, so that only the 2 nd byte of the MMTP header needs to be parsed to obtain the payload type corresponding to the TLV data packet, so that the data processing efficiency is improved.
And S200, when the payload type is a preset payload type, filtering the TLV data packet.
In this embodiment, filtering is performed before the data packet is copied to the user layer, so that unnecessary data is not copied to the user layer, and generally, the system bandwidth can be reduced by half. Correspondingly, when the payload type is a preset payload type, filtering the TLV packet specifically includes: and discarding the TLV data packet when the payload type is a preset payload type. Therefore, in the invention, firstly, the payload type of the TLV data packet is judged, then when the payload type of the TLV data packet is MPU type, the TLV data packet is discarded, for example, under the condition that a user searches a channel, the MPU type data is not needed, so the TLV data packet with the MPU type can be discarded directly. In practical applications, when the user uses the play function of the program, numbers may be set in the system, where each number represents program information that the user needs to use the play function, so in an implementation manner of this embodiment, when the payload type is a preset payload type, filtering the TLV packet specifically includes:
when the payload type is a preset payload type, acquiring a number corresponding to the TLV data packet;
and discarding the TLV data packet when the number is not matched with the preset number.
Specifically, the preset number is set according to the actual requirement of the user, namely, the number of the TLV data packet can be obtained, and compared and matched with the preset number, when the number is found to be consistent with the preset number, the user is required to use the TLV data, so that the TLV data packet is required to be thrown to a user layer, the data copy from a kernel to the user layer is reduced, the system bus occupation is reduced, the discarded data cannot be copied to the user layer, the user layer processing data amount is reduced, and the cpu loading is reduced; when the number is not found to be consistent with the preset number, the user is not required to use the TLV data packet, so that the TLV data packet is required to be discarded. The embodiment of the invention provides a method for realizing an efficient TLV filter, which reduces bandwidth consumption and cpu loading, and is suitable for systems with different hardware configurations. And, do not increase the hardware cost, can multiplex TLV Demux (the resolver) to process information, have extensive adaptability.
Further, in an implementation manner of this embodiment, filtering the TLV packet may further be determined according to a usage scenario, and when the payload type is a preset payload type, the filtering the TLV packet specifically includes:
m01, when the payload type is a preset payload type, acquiring a use scene of the television;
m02, discarding the TLV data packet when the usage scenario is a first usage scenario;
m03, when the use scene is a second use scene, acquiring a number corresponding to the TLV data packet;
m04, discarding the TLV data packet when the number is not matched with a preset number.
Specifically, the usage scenario includes a scene such as a search or a program playing, and in this embodiment, the first usage scenario is a scene such as a search, and the second usage scenario is a scene such as a program playing, so that the invention provides convenience for users by judging the usage scenario of the television and adopting different filtering modes according to the usage scenario.
It will be appreciated that when the payload type corresponding to the TLV packet is not the MPU type, then the TLV packet is the TLV-SI/MMT-SI type, and the user layer organizes the play information before playing, for example, obtaining the program resolution, obtaining the descrambling information, and so on. The TLV packet will still be sent normally to the user layer.
