An adaptive multi-view streaming processing method and apparatus for a multi-view stream is disclosed. Specifically, disclosed herein is a method and apparatus for adaptively processing or transmitting adaptive streaming by reflecting network states and changes in transmission environments in a multi-view streaming service environment where several or more multiple videos are simultaneously transmitted at an arbitrary moment. An adaptive streaming processing method for a multi-view stream may comprise selecting and downloading an i-th segment of a main view stream with a first quality level, inferring a size of an i-th segment of downloadable neighboring view streams based on a download time and transfer rate of the i-th segment of the main view stream, and selecting a second quality level corresponding to the inferred size of the i-th segment of the neighboring view streams and downloading the i-th segment of the neighboring view streams based on the selected second quality level.

Method and apparatus for processing adaptive multi-view streaming

An apparatus and a method for processing an uplink signal of cable broadcasting network including: modulating uplink data to be transmitted to a broadcasting station which is located at an end of the cable broadcasting network into a plurality of symbols; performing a correlation-coding on the plurality of symbols; and outputting an analog radio frequency (RF) signal corresponding to the plurality of correlation-coded symbols are provided.

Method and apparatus for processing uplink signal in cable broadcasting network

A method and an apparatus of interactive advertising service are provided. The method includes: receiving first advertising contents from a broadcasting advertisement platform; displaying broadcasting according to the first advertising contents on the overall screen together with at least one second advertisement contents interactive indicator indicating that the first advertising contents are linked with second advertising contents; receiving indicated information triggering at least one second advertising contents interactive indicator from an input device; receiving the second advertising contents indicated by the at least one second advertising contents interactive indicator from the broadcasting advertisement platform; and displaying broadcasting according to the second advertisement contents. According to an exemplary embodiment of the present invention, it is possible to introduce opportunity of goods information acquisition and purchasing behaviors distributed to media other than broadcasting into a smart TV while improving concentration for advertisements in bidirectional digital broadcast.

Method and apparatus of interactive advertising service in digital broadcast system

Disclosed is a system for providing an Evolved Multimedia Broadcast/Multicast Service (EMBMS) chatting service for providing a multi-chatting service. The system comprises at least one of a User Equipment (UE) to request establishment of a chatting channel and to transmit and receive a communication message and contents so as to transmit and receive the communication message with a plurality of mobile subscribers participated in the chatting channel, an evolved Broadcast Multicast-Service Center (eBM-SC) to perform control of an EMBMS service so as to transmit the communication message to the at least one of the UE using the EMBMS service, and a service provider server to transmit, to the eBM-SC, user service information, first bearer service information, and contents for each of the chatting channels, so that the UE transmits and receives the communication message with the plurality of the mobile subscribers participated in the chatting channel.

System for providing EMBMS chatting service and service provider server of the same, and method for controlling eBM-SC and user equipment

Disclosed are a system and a method for receiving an MBMS broadcasting service. In the present invention, in a mobile communication/wireless communication system, an MBMS service is provided by synchronizing a unicast bearer with a multicast bearer through scheduling information mapping at the time of transmitting a broadcast/multicast service through a unicast. Further, the present invention presents even a method for improving quality of experience (QoE) of the service by providing the MBMS service through the multicast bearer and the unicast bearer simultaneously. According to the present invention, MBMS services of various service qualities can be provided depending on wireless quality of a terminal or the capability of the terminal at the time of providing the MBMS service.

System and method for receiving MBMS broadcasting service

Provided is a method and apparatus for reducing zapping delay, which may transmit base layer data for each burst in a time-slicing scheme, and output the base layer data of a channel to be changed at the time of changing the channel, thereby reducing the zapping delay.
