Abstract
Disclosed herein are a method and apparatus of broadcast gateway signaling for channel bonding. The apparatus for broadcast gateway signaling includes an input formatting unit configured to generate baseband packets corresponding to channel bonding; and a stream partitioner configured to allocate the baseband packets to two or more RF channels of the channel bonding for generating an outer tunnel data stream, the outer tunnel data stream generated in different ways according to a plurality of operation modes for the channel bonding.
Claims12
A broadcast gateway apparatus, comprising:
- an input formatting unit configured to generate baseband packets corresponding to channel bonding;
- and
- a stream partitioner configured to allocate the baseband packets to two or more RF channels of the channel bonding for generating an outer tunnel data stream, the outer tunnel data stream generated in different ways according to operation modes for generating the outer tunnel data stream,
- wherein the channel bonding is performed by plain channel bonding or SNR averaging channel bonding,
- wherein the operation modes include:
- a first mode in which one outer tunnel data stream is generated for each of the two or more RF channels;
- and
- a second mode in which one outer tunnel data stream is generated for the two or more RF channels,
- wherein the one outer tunnel data stream of the first mode includes one inner tunneled packet stream group for one among the two or more RF channels, and the one outer tunnel data stream of the second mode includes two or more inner tunneled packet stream groups, the two or more inner tunneled packet stream groups being for the two or more RF channels, respectively.
