Abstract
In a digital broadband broadcasting system, in which information is transmitted and received periodically in bursts to reduce receiver power consumption, time-slice information is provided from the transmitter to the receiver. The time-slice information can include information from which the receiver can determine when a subsequent transmission burst will be transmitted. The time-slice information can include a burst duration, an amount of time between original bursts, the time between an original burst and a copy of the burst, and numbering of original bursts. This type of time-slice information can be placed into packet headers, such as one or more bytes reserved, but not used, for media access control addressing.
Claims51
A time-slicing digital broadcasting transmitter system comprising:
- a buffer that receives information from an information service provider;
- an encapsulator that receives buffered information from the buffer and that forms at least one packet header that contains time-slice information that includes a time-slice parameter specifying a relationship between a current packet of a current burst of packets and a subsequent burst of packets;
- and
- a digital broadcast transmitter that transmits bursts of packets that include the time-slice information.
A mobile terminal that receives time-slicing digital broadcast information, the mobile terminal comprising:
- a digital broadcast receiver that receives bursts of packets that include time-slice information and that have been transmitted by a digital broadcast transmitter;
- a buffer that receives time-slice information;
- and
- an application processor that receives buffered time-slice information from the buffer and that decodes the buffered time-slice information thereby extracting information that specifies a relationship between a current packet of a current burst of packets and a subsequent burst of packets.
A time-slicing digital broadcasting system comprising:
- a digital broadcast transmitter system that transmits bursts of packets that include information from at least one data service of at least one information service provider and that include time-slice information that specifies a relationship between a current packet of a current burst of packets and a subsequent burst of packets;
- and
- a digital broadcast receiver system that receives the bursts of packets and that decodes the time-slice information thereby extracting information that specifies the relationship between the current packet and the subsequent burst of packets.
A method of transmitting time-slicing digital broadcast information, the method comprising:
- buffering information received from at least information service provider;
- and
- forming packets including the buffered information and packet headers that contain time-slice information that specifies a plurality of relationships between a plurality of packets of a current burst of packets and a subsequent burst of packets.
A method of receiving time-slicing digital broadcast information, the method comprising:
- receiving bursts of packets that include time-slice information and that have been transmitted by a digital broadcast transmitter, wherein the time-slice information specifies a relationship between a current packet of a current burst of packets and a subsequent burst of packets;
- buffering the time-slice information;
- and
- decoding the buffered time-slice information to extract information that specifies the relationship between the current packet and the subsequent burst of packets.
