Embodiment 3

[0112] In the third embodiment, when the information to be transmitted is encapsulated into the DSM-CC segment by the information encapsulation method based on the data carousel, it is also necessary to add new implementation content to the steps 4 and 5 of the embodiment 1:

[0113] The step 4 also includes: loading the encapsulated DSM-CC segments into the TS packet identified by the empty packet PID number;

[0114] The step 5 also includes: indicating the use of related data carousels in the PSI table and / or the SI table in accordance with national standards. The specific approach is as follows:

[0115] In the data_carousel_info structure under the data_broadcast_descriptor descriptor in the SDT table, set the transactionId of the DII message or DSI message that contains the relevant data carousel. The two LSB bytes of this transactionId are the same as the one that loaded the DII message or DSI message. The table_id_extension value of the DSM-CC segment shall be equal.

Embodiment 4

[0120] In the fourth embodiment, when the information encapsulation method based on object carousel is adopted in the step 2 to encapsulate the information to be transmitted into the DSM-CC segment, it is also necessary to add new ones to the steps 4 and 5 of the embodiment 1. Implementation content, namely:

[0121] The step 4 also includes: loading the encapsulated DSM-CC segments into the TS packet identified by the empty packet PID number;

[0122] The step 5 also includes: indicating the use of the relevant object carousel in any combination of the PSI table, the SI table, the AIT table or the PSI table, the SI table and the AIT table in accordance with national standards. The specific approach is as follows:

[0123] In the object_carousel_info structure under the data_broadcast_descriptor descriptor in the SDT table, set the transactionId of the DSI message containing the identifier of the relevant object carousel. The two LSB bytes of this transactionId are the same as the D...

Embodiment 5

[0125] In the fifth embodiment, when the information encapsulation method based on the data stream is used in step 3 to encapsulate the to-be-transmitted information into a PES packet, it is also necessary to add new implementation content to steps 4 and 5 of the first embodiment, namely:

[0126] The step 4 also includes: loading the encapsulated PES package into the TS package identified by the empty package PID number;

[0127] The step 5 also includes: referring to the national standard to indicate the use of the relevant data stream in the PSI table and / or the SI table.

Abstract

The invention relates to a method for transmitting information by using section mark fields or PES (packetized elementary streams) packet mark fields. The method comprises the following steps that 1, information to be transmitted is organized at an information sending end, and the second step and / or the third step are / is executed; 2, the information to be transmitted is encapsulated into the section, and in addition, the section mark fields are set; 3, the information to be transmitted is encapsulated into the PES packets, and in addition, the PES packet mark fields are set; 4, the section and / or the PES packet are / is loaded to a TS (transport stream) packet identified by a vacant packet PID (proportion integration differentiation) number; 5, information loaded in the section and / or the PES packet is described in a relevant table; 6, the relevant table is loaded into the TS packet identified by the vacant packet PID number or the TS packet identified by the PID number according to standard regulations; 7, the TS packet identified by the vacant packet PID number is arranged; 8, the arranged TS packet is used for replacing the vacant packet in the TS stream in a transmission channel; and 9, the TS stream is received at the information receiving end, and in addition, the carried relevant table and the transmission information are processed. The method has the advantage that the low-carbon, green and environment-friendly information service is favorably realized.

Description

Technical field [0001] The present invention relates to the information technology field of a digital television system or an IPTV system, in particular to a method for transmitting information using a segment flag field or a PES packet flag field. Background technique [0002] Information service systems and methods based on digital television systems or IPTV systems in the prior art fail to make good use of empty packets for information transmission, and waste some resources. Therefore, the use of empty packets for information transmission is conducive to the realization of low-carbon, green and environmentally friendly information services. Aiming at the empty packet replacement technology, the present invention proposes a method for transmitting information using a section flag field or a PES packet flag field. [0003] The meanings of the corresponding terms and flag fields involved in the present invention are as follows: [0004] TS: Transport Stream, which is the protocol o...
