I have read some documentation in [1] and [2] but still unclear.. Assume Hierarchical B/P GOP structures are possible. - Do P-frames still have only 1 reference frame ? (either a B/I frame) ? or can a … Webthe hierarchical-B coding structure is well-known for random access applications, the hierarchical-P structure is more appropriate for low delay cases. The pros and cons of the hierarchical-P structure are well presented in Reference [14]. The hierarchical-P RPS method generates a control picture upon receiving a feedback signal from the decoder.
