Problems solved by technology

[0010] It should be noted that the above is only a combination of specific parameters in the ATSC3.0 standard to reflect the background technical problems such as insufficient use of spectrum resources and insufficient acquisition of additional information capacity. problem, but a technical problem that also applies to the same principles encountered in other transport protocol standards

Embodiment Construction

[0038] The skipping mode discussed in this invention can be applied to both its innovative Internet service and traditional broadcast service and other communication transmission fields. In addition to the high-speed motion service reception of the new service of ATSC3.0, this suggestion can also be applied For other types of services, such as handheld mobile reception (pedestrian and in-door) using mobile phones or tablets and "fixed reception in the home" using rooftop or indoor antennas / set-top boxes / large-screen displays (fixed receptions in the home)", which is also applicable to other communication transmission protocol standards,

[0039] Through the skipping mode of the present invention, the latter two (handheld mobile reception and fixed reception at home) although the increase in information capacity is not much, the robustness of the preamble can still be significantly enhanced.

[0040] In this manual, the term suitable for high-speed motion reception is used beca...

Abstract

The invention provides a design method for a data frame suitable for high-speed motion reception and a transmission system. The design method is characterized in that a data frame comprises a self-bootstrap program, a prefix code and at least one data sub-frame, which are cascaded with each other, and the self-bootstrap program does not need to be transmitted on each data frame. A gap is reservedwhen the self-bootstrap program is not transmitted in the data frame and is used for obtaining extra information capacity, wherein the time domain is evenly divided into a plurality of time segments according to the duration of the data frames, and skipping at the time within a certain range before and after the change moment of the technical mode combination TMC is avoided. At least one skipped time fragment is uniformly distributed in other remaining time, and the data frames in the skipped time fragment do not transmit the self-bootstrap program. On the premise that the change of the technical combination mode is not affected, robustness enhancement and information capacity increase are achieved.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a design method and a transmission system of a data frame suitable for high-speed motion reception. Background technique [0002] ATSC (Advanced Television System Committee) released A / 321 bootloader and A / 322 physical layer protocol in March 2016 and September 2016. The two standards are A / 321 standard, system discovery and detection, March 23, 2016; and the A / 322 standard, physical layer protocol, September 7, 2016. [0003] Among them, the bootstrap of A / 321 and the preamble of A / 322 have excellent performance, and they are ready to start the new service of ATSC3.0. This standard is applicable to 6, 7, 8 and 2 * 5 = 10MHz channel bandwidth, the advantages are obvious, the performance is relatively good, and it has been first launched in South Korea. [0004] However, the advantages also bring disadvantages. This standard does not make full use of spectrum resources i...
