Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Powerline T

Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions)

Introduction This Technical Report investigates how to transmit over the powerline medium HD and UHD contents that typically are exchanged through the HDMIcable between transmitter video sources like Bl
23、u-ray players or set-top boxes and receiver video sinks like video displays. The report also presents earlier findings. The scope of the Technical Report is providing the technical elements needed to establish a PHDMI specification. The report is structured as follows: in clause 4, the requirements
24、in terms of target bit rate to be fulfilled by a PHDMI technology are presented for different HD and UHD formats together with a set of PLT links used for testing purposes. It has to be underlined that the initial target for phase 1 was only HD. It was however estimated that the market is rapidly mo
25、ving towards UHD and it was hence decided to enlarge the scope to also cover UHD. In clause 5, some target use cases are described: these scenarios highlight the potential fields of application of a PHDMI technology. Clause 6 presents the schemes that have been scrutinized as potential PHDMI technol
26、ogies. Two of them are tandem schemes, i.e. systems that separate the channel encoding part from the source encoding part, they are based upon the serial concatenation of a compression encoder (based upon JPEG 2000 or Dirac) specifications and a OFDM power line modem operating in the 2 MHz to 100 MH
27、z band that is able to provide SISO-based or MIMO-based communication. Besides tandem scheme, a joint scheme relying on the SoftCast paradigm has been also considered: it accommodates joint source and channel encoding. These communication schemes have been tested on HD and UHD videos both on flat ch
28、annel with AWGN and on realistic PLT links (both SISO, MIMO 22 and MIMO 23): results are reported in terms of video quality metrics in clause 7 and clause 8. In particular, it is worth noticing that a realistic long video sequence was furnished by France Tlvision for this analysis. Clause 9 shows ho
29、w to optimize the source encoder parameters for the tandem schemes: an interesting point that it is also evaluated in this clause is the resiliency to errors at the PLT level, i.e. the investigation to see if it is possible to tolerate some errors at the PLT level without requiring retransmission of
30、 wrong packets. Clause 10 presents a scheme of a rate controller: it is the PHDMI component that manages the compression encoder rate as a function of eventual changes of the PLT rate during the video transmission. Transmit and receive buffer requirements are also put in evidence. Conclusion and fin
31、al recommendations are reported in clause 11 of the present document. NOTE: Blu-ray is an example of a suitable product available commercially.
