This Recommendation provides radio-frequency channel arrangements for point-to-point (P-P) fixed wireless systems operating in the 42 GHz (40.5 to 43.5 GHz) band, which may be used for high, medium and low capacity systems. The preferred radio-frequency channel arrangements are based on multiples of basic channels of 7 MHz width merged to form higher channel widths up to 112 MHz. Additional option for block arrangement suitable for deployment of a variety of fixed wireless access (FWA) systems using multipoint technology as well as PP links for infrastructure and access purpose. Third option for a flexible mixed use of the above deployment methodology is also described.

ITU-T P.1202.1-2012 视听媒体流质量的参数性非介入评估.低分辨率应用领域.12号研究组

This Recommendation 1 describes an algorithmic model for parametric non-intrusive bitstream assessment of video media streaming quality – lower resolution (LR) application area. This algorithmic model can be applied to the monitoring of the video quality of IP-based video services based on information extracted from the video bitstream encoded with the ITU-T H.264/AVC baseline video codec. The model is intended especially for the lower resolution application area, including such services as mobile TV. The ITU-T P.1202.1 model is a no-reference (i.e., non-intrusive) model which operates by analysing information in the video bitstream without fully decoding the bitstream. Further client specific information, such as concealment type and rebuffering duration, is provided to the algorithm out-of-band, for example in the form of stream-specific side information. As output, the model algorithm provides an estimate of the video quality in terms of the five-point absolute category rating (ACR) mean opinion score (MOS) scale defined in [ITU-T P.910]. This Recommendation describes the algorithm that takes an elementary stream encapsulated in RTP/UDP/IP as input, where information from RTP headers is used to identify lost pictures.

ITU-T P.1201.2-2012 视听媒体流质量的参数性非介入评估.质量高分辨率应用领域.12号研究组

This Recommendation 1 specifies the algorithmic model for the higher resolution (HR) application area of [ITU-T P.1201]. [ITU-T P.1201] specifies models for monitoring the audio, video andaudiovisual quality of IP-based video services based on packet-header information. The higher resolution application area of the ITU-T P.1201.2 part of [ITU-T P.1201] can be applied to the monitoring of performance and quality of experience (QoE) of video services such as IPTV. The algorithm for the lower resolution case is specified in [ITU-T P.1201.1]. See [ITU-T P.1201] for details and respective application ranges.

ITU-T P.1201.1-2012 视听媒体流质量的参数性非介入评估.低分辨率应用领域.12号研究组

Recommendation ITU-T P.1201.1 1 describes an algorithmic model (ITU-T P.1201-LR: Parametric non-intrusive assessment of audiovisual media streaming quality – Lower resolution application area) for monitoring the audio, video and audiovisual quality of IP-based video services based on packet-header information. ITU-T P.1201.1 addresses the lower resolution (LR) application area, including services such as mobile TV. The ITU-T P.1201-LR model is a no-reference (i.e., non-intrusive) model which operates by analysing packet header information. Further input information on more general aspects of the stream, such as the video resolution, which may not be available from packet header information, is provided to the algorithm out-of-band, for example in the form of stream-specific side information. As output, the model provides individual estimates of audio, video and audiovisual quality in terms of the five-point absolute category rating (ACR) mean opinion score (MOS) scale. This Recommendation is to be used with media payload (audio, video) encapsulated in RTP/UDP/IP packets.
