Inputs

| object | Channel | The channel to read from |
| struct | Access Context | Context allowing passing of NDC type specific information between the caller and internal Data Channel that can control internal routing and help feedback information to the caller. |
| boolean | Read Previous Frame | True if this reader will read the previous frame's data. If false, we read the current frame. Reading the current frame allows for zero latency reads, but any data elements that are generated after this reader is used are missed. Reading the previous frame's data introduces a frame of latency but ensures we never miss any data as we have access to the whole frame. |
