Abstract
Transmission of TCP/IP data over a satellite link from a hub station to a plurality of remote units. The data, transmitted over the satellite link, uses the digital video broadcast (DVB) protocol. A field in the DVB header is used to indicate the location of the start of a new TCP/IP data packet within the DVB data. Use of a field in the DVB header to indicate the location of the start of a new TCP/IP data packet supports variable location of TCP/IP data within a DVB frame, and therefore more efficient use of the DVB bandwidth.
Claims21
A remote unit in a communication system comprising:
- a DVB receiver having an input port configured to be coupled to an RF receiver and an output port configured to produce a standard DVB data frame;
- and
- a DVB to MAC converter having an input port coupled to the output port of the DVB receiver and configured to accept a standard DVB data frame and an output port configured to produce a de-fragmented MAC data frame, wherein the DVB data frame has MAC fragment headers occurring at a variable location within the DVB frame.
A method of receiving data in a remote unit of a communication system, comprising:
- storing MAC data in a DVB data frame such that MAC fragment headers occur at variable locations within the DVB data frame;
- receiving the DVB data;
- converting the DVB data to MAC data;
- and
- transferring the MAC data to a LAN.
In a remote unit of a communication system, a method of receiving data comprising:
- storing the position location of MAC fragment headers in a PID field of a DVB data frame;
- receiving the DVB data;
- converting the DVB data to MAC data;
- and
- transferring the MAC data to a LAN.
A remote unit in a communication system, comprising:
- means for receiving DVB data, wherein the DVB data comprises at least one DVB data frame, and wherein the DVB data frame has MAC fragment headers that occur at a variable location within the DVB data frame;
- means for converting the DVB data to MAC data;
- and
- means for transferring the MAC data to a LAN.
A remote unit in a communication system, comprising:
- means for receiving DVB data, wherein the DVB comprises at least one DVB data frame, and wherein a position location of MAC fragment headers is contained in the PID field of the DVB data frame;
- means for converting the DVB data to MAC data;
- and
- means for transferring the MAC data to a LAN.
