Methods and device for processing digital data frames and transport frames for reduction of transport bandwidth
First Claim
1. A method for processing digital data frames to be transmitted by a transport network, said method comprising:
- downsizing digital data frames,compressing the downsized digital data frames wherein the compression comprises frequency down-sampling, scaling blocks of samples by a scaling factor and quantising the scaled blocks of samples to produce compressed samples andthen compacting the compressed digital data frames to produce reduced digital data frames,aggregating at least some of the reduced digital data frames together according to aggregation information to produce frame groups, andgrouping the frame groups being grouped together with a group descriptor, defining initial arrangements of said digital data frames, according to grouping information, to produce a transport frame to be transmitted by the transport network.

Abstract
A device (D1) is intended for processing digital data frames to be transmitted by a transport network (TN), and comprises i) a first processing means (PM1) comprising ports for receiving digital data frames and arranged for downsizing, then compressing, if necessary, and then compacting each one of these received digital data frames to produce reduced digital data frames, ii) a second processing means (PM2) arranged for aggregating at least some of these reduced digital data frames together according to aggregation information to produce frame groups, and iii) a third processing means (PM3) arranged for grouping these frame groups together with a group descriptor, defining initial arrangements of the digital data frames, according to grouping information, to produce a transport frame to be transmitted by the transport network (TN).

8. A method for processing a transport frame transmitted by a transport network, said method comprising:
-
receiving a transport frame produced by a process comprising; downsizing digital data frames, compressing the downsized digital data frames, wherein the compression comprises frequency down-sampling, scaling blocks of samples by a scaling factor and quantising the scaled blocks of samples to produce compressed samples and then compacting the compressed digital data frames to produce reduced digital data frames, aggregating at least some of the reduced digital data frames together according to aggregation information to produce frame groups, and grouping the frame groups being grouped together with a group descriptor, defining initial arrangements of said digital data frames, according to grouping information, to produce a transport frame to be transmitted by the transport network de-grouping frame groups it comprises, de-aggregating each of the frame groups to get reduced digital data frames they comprise, and un-compacting, then de-compressing if compressed, and then upsizing each one of the reduced digital data frames according to information contained into a group descriptor of the transport frame to get digital data frames. - View Dependent Claims (9, 10, 11, 12)
