This application claims the priority benefit of Korean Application No. 10-2008-0092361, filed on Sep. 19, 2008, which is hereby incorporated by reference as if fully set forth therein.
This application claims the benefit of U.S. Provisional Application No. 60/973,773, filed on Sep. 20, 2007, U.S. Provisional Application No. 60/974,084, filed on Sep. 21, 2007, U.S. Provisional Application No. 60/977,379, filed on Oct. 4, 2007, U.S. Provisional Application No. 61/044,504, filed on Apr. 13, 2008, U.S. Provisional Application No. 61/076,686, filed on Jun. 29, 2008, which are hereby incorporated by reference.
According to an embodiment of the present invention, the signaling information area for inserting signaling information may start from the 1st segment of the 4th MH block (B4) to a portion of the 2nd segment. More specifically, 276 (=207+69) bytes of the 4th MH block (B4) in each data group are assigned as the signaling information area. In other words, the signaling information area consists of 207 bytes of the 1st segment and the first 69 bytes of the 2nd segment of the 4th MH block (B4). The 1st segment of the 4th MH block (B4) corresponds to the 17th or 173rd segment of a VSB field.
FIG. 8 illustrates an exemplary assignement order of data groups being assigned to one of 5 sub-frames, wherein the 5 sub-frames configure an MH frame. For example, the method of assigning data groups may be identically applied to all MH frames or differently applied to each MH frame. Furthermore, the method of assigning data groups may be identically applied to all sub-frames or differently applied to each sub-frame. At this point, when it is assumed that the data groups are assigned using the same method in all sub-frames of the corresponding MH frame, the total number of data groups being assigned to an MH frame is equal to a multiple of ‘5’.
According to the embodiment of the present invention, the RS frame being assigned to regions A/B within the corresponding data group will be referred to as a “primary RS frame”, and the RS frame being assigned to regions C/D within the corresponding data group will be referred to as a “secondary RS frame”, for simplicity. Also, the primary RS frame and the secondary RS frame form (or configure) one parade. More specifically, when the mobile service data within one RS frame are assigned either to all of regions A/B/C/D within the corresponding data group, one parade transmits one RS frame. Conversely, when the mobile service data within one RS frame are assigned either to at least one of regions A/B and regions C/D, one parade may transmit up to 2 RS frames.
For example, when it is assumed that data groups corresponding to a parade are assigned as shown in FIG. 9, data groups corresponding to the next parade may be assigned to a sub-frame starting either from the 12th slot of a sub-frame. However, this is merely exemplary. In another example, the data groups of the next parade may also be sequentially assigned to a different slot within a sub-frame at a cycle period of 4 slots starting from the 3th slot.
The virtual_channel_target_IP_address_flag field is a 1-bit Boolean flag, which indicates, when set, that the corresponding IP stream component is delivered through IP datagrams with target IP addresses different from the virtual_channel_target_IP_address. Therefore, when the flag is set, the receiving system (or receiver) uses the component_target_IP_address as the target_IP_address in order to access the corresponding IP stream component. Accordingly, the receiving system (or receiver) may ignore the virtual_channel_target_IP address field included in the num_channels loop.
Referring to FIG. 28, the GSE packet header may include at least one of a Start_Indicator(S) field, an End_Indicator(E) field, a Label_Type_Indicator(LT) field, a GSE_Length field, a Fray_ID field, a Total_Length field, a Protocol_Type field, a Label field, and an Extension_Header_Bytes field. The Start_Indicator(S) field may include specific information indicating a start part of the encapsulated PDU in the GSE packet, and may have the size of one bit. The End_Indicator(E) field may include specific information indicating the end of the encapsulated PDU in the GSE packet, and may have the size of one bit. The Label_Type_Indicator(LT) field may include padding information, and may have the size of 2 bits. The GSE_Length field may include specific information indicating the length of the GSE packet, and may have the size of 12 bits. The Frag_ID field may include specific information indicating whether the PDU fragment is contained in the GSE packet, and may have the size of 1 byte. If the Start_Indicator(S) field and the End_Indicator(E) field are established, the Frag_ID field may include specific information indicating the absence of the PDU fragment in the GSE packet. The Total_Length field may be contained in the header of the GSE packet including a first fragment of the fragmented PDU, may include total length information of the fragmented PDU, and may have the size of 2 bytes. The Protocol_Type field may include specific information indicating a type of the payload delivered by the PDU contained in the GSE packet, and may have the size of 2 bytes. The Label field may include label information used for an addressing operation, and may have the size of 3/6 bytes. The Extension_Header_Bytes may be reserved for the extended header format, and may have the size of 2 bytes or the size of at least 2 bytes.
