Definitions

  • Figure 2 illustrates a system for transmitting and receiving bursts of content, in accordance with an embodiment of the invention
  • Figure 5 illustrates a method that may be used by a mobile terminal to receive and process bursts of content in accordance with an embodiment of the invention
  • FIG. 2 illustrates a system for transmitting and receiving bursts of content in accordance with an embodiment of the invention.
  • the content may include audio content, video content and/or data.
  • a head-end 202 transmits bursts of content to a mobile terminal 204 via a digital video broadcast network 206.
  • a single mobile terminal is shown for illustration purposes only and with the understanding that head- end 202 may transmit bursts of content to numerous mobile terminals or other devices.
  • Digital video broadcast network 206 may include coaxial cable, a wireless transmission station, a satellite or other transmission medium.
  • aspects of the present invention may utilize networks other than digital video broadcast networks, such as pure Internet protocol networks.
  • Head-end 202 may receive an information signal 208 at a buffer 210.
  • Buffer 210 may be a memory that stores segments of information signal 208.
  • An interval module 212 may be used to determine a relative time period between the transmission of bursts of content. The relative time period determined by interval module 212 may be a function of a maximum bandwidth of network 206, a maximum bandwidth of a channel of network 206 or other factors, such as power management efficiencies of the head-end and/or mobile terminal.
  • the head-end determines a relative time period between the transmission of the first and second bursts.
  • the relative time period may be a function of the content of the original content stream, the available bandwidth of the transmission medium or the available bandwidth of a channel of the transmission medium.
  • the relative time period is encoded in the first burst of content data in step 410.
  • the relative time period may be included in an Internet protocol (IP) packet, a multiprotocol encapsulated frame, any other packet frame, a 3G or GPRS channel or modulation data, such as transmitter parameter signaling.
  • IP Internet protocol
  • the first burst is transmitted to the transmission medium.
  • the second burst is transmitted to the transmission medium in step 414.
  • step 506 power is removed from at least a portion of the mobile terminal for a time period less than the first relative time period.
  • power is removed from receiving module 222.
  • Receiving module 222 may include components that consume relatively large amounts of power, such as a demodulator.
  • mobile terminal 204 may be configured so that power is selectively applied to additional components. For example, power may be removed from substantially all of the components of the mobile terminal in between the reception of bursts of content. Power may be removed from substantially all of the components when, for example, the mobile terminal is receiving content that will be presented to a user at a later time. Mobile terminal 204 may receive the content and store the content in a memory for later retrieval.
  • FIG. 6 illustrates an embodiment in which relative timing information is included in an adaptation field 502 of an MPEG II transport stream packet.
  • Adaptation field control bits 506 included in an MPEG II header 506 may be used to signal the presence of the relative timing information in adaptation field 502.
  • adaptation control field 504 includes two bits. A bit value of "00” may indicate that the adaptation field is reserved for future use, a bit value of "01” may indicate that a payload is present, but an adaptation field is not present, a bit value of "10” may indicate that an adaptation field is present, but no payload is present, and a bit value of "11” may indicate that an adaptation filed and payload are present.
