• Back Channel transmissions (BC-BC): Similar to forward channel
transmissions, back channel information such as video capture and
motion tracking, may require tight synchronization to other context and
control information, such as other sensor data or audio.
Conclusion: Solution Space & Areas of Focus
As discussed, emerging technologies will create new demands for bandwidth
and lower latency applications. The emergence of edge and cloud services will
enable compute offload for the end user, but with the cost of further increasing
requirements placed on forward and backchannel transmissions, including the
need to synchronize specific services, resulting in constrained connectivity at
various levels of the compute hierarchy.
To improve performance within these constraints, particularly while adhering to
existing standards, several methods may be considered for improving overall
performance. Using standard forward channel transmission techniques such as
selective video encoding, resiliency, and concealment techniques, common in
AV transmissions, is one area of focus. Using novel backchannel transmission
techniques such as Region of Interest (ROI) tracking, tracking data encoding,
resiliency and concealment techniques, is another area of focus. Lastly,
keeping the various heterogenous workstreams on forward channel and back
channel in relative contextual synchronization in a multi-prong architecture is an
area of focus.
