Abstract
The present technology relates to data processing devices and data processing methods that lower costs and enable CB (Channel Bonding). A transmission device divides a BB stream as a stream of BB (Baseband) frames into divisional streams by distributing the BB frames of the BB stream to data slices. The dividing of the BB stream is performed by limiting the data rate ratio between the data rates of the divisional streams. A reception device recomposes the original BB stream from the divisional streams obtained from data transmitted from the transmission device. The present technology can be applied to CB such as PLP (Physical Layer Pipe) bundling.

A data processing device comprising:
- a processing circuit configured to:
- receive a baseband (BB) stream;
- and
- divide the BB stream as a stream of BB frames into a plurality of divisional streams by distributing groups of uninterrupted BB frames of the BB stream to a plurality of data slices for output,
- wherein
- the groups of uninterrupted BB frames are distributed to the data slices in a manner that a data rate ratio between data rates of two of the divisional streams is set based on a transmission rate ratio between corresponding two of the data slices,
- the BB frames are distributed to the data slices in a manner that the data rate ratio between the data rates of the two of the divisional streams is limited to 2.2, and
- a number of BB frames in any of the groups of uninterrupted BB frames is equal to or less than 10.
