Time-slice signaling for broadband digital broadcasting
First Claim
1. A time-slicing digital broadcasting transmitter system comprising:
- a buffer that receives at least one of digital video content and digital audio content from an information service provider;
an encapsulator that receives the buffered content from the buffer and that forms at least one packet header for a current packet of a current burst of packets, wherein the current packet contains a first portion of the buffered content, wherein the at least, one packet header contains time-slice information that includes a time-slice parameter specifying a relationship between the curent packet of the current burst of packets and a subsequent burst of packets that contains a second portion of the buffered content; and
a digital video broadcast transmitter that transmits the current burst of packets and the subsequent burst of packets, thereby allowing a digital-video-broadcast receiver to enter a reduced power-consumption state for a duration, which is based at least in part on the time-slice parameter, between receiving the current burst of packets and receiving the subsequent burst of packets.

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.

14. A mobile terminal that receives time-slicing digital video broadcast information, the mobile terminal comprising;
-
a digital video broadcast receiver that receives a current burst of packets and a subsequent burst of packets, wherein the current burst of packets includes a current packet that includes at least one of digital video content and digital audio content and that includes time-slice information, wherein the current burst of packets and the subsequent burst of packets that have been transmitted by a digital video broadcast transmitter; a buffer that receives the current burst of packets and the subsequent burst of packets; and an application processor that receives the current packet'"'"'s buffered content and time-slice information from the buffer and that decodes the current packet'"'"'s buffered time-slice information thereby extracting information that specifies a relationship between the current packet of the current burst of packets and the subsequent burst of packets, thereby allowing the mobile terminal to enter a reduced power-consumption state for a duration, which is based at least in part on the extracted information, between receiving the current burst of packets and receiving the subsequent burst of packets. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A time-slicing digital video broadcasting system comprising:
-
a digital video broadcast transmitter system that transmits bursts of packets, including a current burst of packets and a subsequent burst of packets, wherein the current burst of packets includes a current packet that includes at least one of digital video content and digital audio content from at least one data service of at least one information service provider and that includes time-slice information that spccifies a relationship between the current packet of the current burst of packets and the subsequent burst of packets; and a digital video broadcast receiver system that receives the current burst of packets and the subsequent burst of packets and that decodes the time-slice information thereby extracting information that specifies the relationship between the current packet and the sub sebsequent burst of packets, thereby allowing the digital video broadcast receiver system to enter a reduoed power-consumption state for a duration, which is based at least in part on the extracted information, between receiving the current burst of packets and receiving the subsequent burst of packets. - View Dependent Claims (25, 26, 27, 28, 29)

30. A method of transmitting time-slicing digital video broadcast information, the method comprising:
-
buffering at least one of digital video content and digital audio content received from at least one information service provider; and forming a plurality of packets of a current burst of packets, wherein the plurality of packets includes portions of the buffered content and a plurality of respective packet headers for the plurality of packets, wherein the packet headers contain time-slice information that specifies a plurality of relationships between the plurality of packets of the current burst of packets and a subsequent burst of packets, thereby allowing a digital-video-broadcast receiver to enter a reduced power-consumption state for a duration, which is based at least in part on the time-slice information, between receiving the current burst of packets and receiving the subsequent burst of packets. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A method of receiving time-slicing digital video broadcast information, the method comprising:
-
receiving a current packet of a current burst of packets and a subsequent burst of packets, wherein the current packet includes time-slice information, wherein the current packet and the subsequent burst of packets include at least one of digital video content and digital audio content from an information service provider and have been transmitted by a digital video broadcast transmitter, wherein the time-slice information specifies a relationship between the current packet of the current burst of packets and the 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, thereby allowing a digital video broadcast receiver to enter a reduced power-consumption state for a duration, which is based at least in part on the extracted information, between receiving the current burst of packets and receiving the subsequent burst of packets. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51)
