Samsung Speeds LTE Broadcast Channel Surfing

Looking to help major wireless carriers use LTE broadcast to compete with cable and satellite TV providers, Samsung says it has a solution that could allow viewers using mobile devices and IP-connected TVs to quickly navigate multiple channels of video programming.

Verizon has used LTE broadcast, or eMBMS (evolved Multimedia Broadcast Multicast Service) to stream a handful of live video feeds to attendees at Indy Car races using its Indy 15 app. AT&T used eMBMS to offer viewers multiple camera angles from the NCAA football championship in January.

While both U.S. wireless carriers and international providers ranging from Deutsche Telecom to South Korea’s KT Corp. have used LTE broadcast to stream programming from live events, Samsung’s invention could help turn LTE broadcast into a platform for delivering dozens of niche programming channels.

Samsung engineer Jin-Bong Ryu is named as lead inventor on the patent application, titled, “Method and Apparatus for Receiving Broadcasting Channel.”

Abstract: An electronic device and a method are provided. The method includes receiving first content data corresponding to a first broadcasting channel while receiving second content data corresponding to a second broadcasting channel; and outputting at least a part of the received first content data to a display connected to the electronic device.

Patent Application

Claims:

  1. A method in an electronic device, the method comprising: receiving first content data corresponding to a first broadcasting channel while receiving second content data corresponding to a second broadcasting channel; and outputting at least a part of the received first content data to a display connected to the electronic device.
  1. The method of claim 1, further comprising outputting the second content data to the display, if a request to play the second broadcasting channel is received while the at least the part of the received first content data is output.
  1. The method of claim 2, wherein outputting the second content data comprises outputting at least a part of the second content data concurrently with the at least the part of the received first content data.
  1. The method of claim 1, wherein the second content data is not output during output of the at least the part of the received first content data.
  1. The method of claim 4, wherein the receiving second content data comprises storing at least a part of the received second content data in a memory.
  1. The method of claim 1, wherein at least a part of the second content data is automatically received based on a predetermined condition.
  1. The method of claim 6, wherein the predetermined condition comprises reception of at least a part of the first content data.
  1. The method of claim 6, wherein the predetermined condition comprises an input to at least one of the electronic device and another electronic device connected to the electronic device.
  1. The method of claim 1, wherein, when the second content data is stored in a memory in an encoded state, and the stored second content data is decoded for output based on a request to play the second broadcasting channel.
  1. The method of claim 1, wherein the second content data corresponding to the second broadcasting channel is stored in a memory in a decoded state, and the stored second content data is output based on a request to play the second broadcasting channel.
  1. The method of claim 1, wherein, if a request to play the second broadcasting channel is not received within a predetermined time while the at least the part of the received first content data is output, stopping reception and processing of the second content data, while continuing to output the at least the part of the received first content data.
  1. An electronic device comprising: a memory for storing content data; and a broadcasting service module connected to the memory, wherein the broadcasting service module is configured to receive first content data corresponding to a first broadcasting channel while receiving second content data corresponding to a second broadcasting channel, and output at least a part of the received first content data to a display connected to the electronic device.
  1. The electronic device of claim 12, wherein the broadcasting service module is further configured to output the second content data to the display, if a request to play the second broadcasting channel is received while the at least the part of the received first content data is output.
  1. The electronic device of claim 12, wherein the memory is configured to store the second content data in the memory in an encoded state, and wherein the broadcasting service module is further configured to decode the stored second content data and output the decoded second content data, based on a request to play the second broadcasting channel.
  1. The electronic device of claim 12, wherein the memory is configured to store the second content data corresponding to the second broadcasting channel in the memory in a decoded state, and wherein the broadcasting service module is further configured to output the stored second content data, based on a request to play the second broadcasting channel.
  1. The electronic device of claim 12, wherein the broadcasting service module is further configured to receive at least one content data corresponding to at least one additional broadcasting channel, based on a request to play the second broadcasting channel.
  1. The electronic device of claim 12, wherein the broadcasting service module is further configured to stop receiving and processing the second content data at least temporarily, while continuing to output the at least the part of the received first content data, if a request to play the second broadcasting channel is not received within a predetermined time while the at least the part of the received first content data is output.
  1. The electronic device of claim 12, wherein the broadcasting service module is further configured to automatically determine the second broadcasting channel based on context information regarding at least one of the electronic device and other devices connected to the electronic device.
  1. The electronic device of claim 18, wherein the context information comprises information regarding the at least one device, including at least one of location, power status, communication status, time, weather, broadcasting schedule, user schedule, and content type of the first content data.
  1. A non-transitory computer-readable recording medium having a program stored thereon for performing a method comprising: receiving first content data corresponding to a first broadcasting channel in an electronic device while receiving second content data corresponding to a second broadcasting channel; outputting at least a part of the received first content data to a display connected to the electronic device; and processing, while outputting the at least the part of the received first content data, at least a part of the received second content data, the processing including at least one of buffering and reproducing the at least the part of the received second content data.
