7. Summary reports from WG Chairmen

Working Group 1 - Voice and video IP applications over cable television networks
Chairman: Gale Lightfoot Jr.

WG 1 (Q8/9) prepared 3 new draft Recommendations for TAP and 2 draft new Recommendations to progress for consent at the next SG 9 meeting.

The three draft new Recommendations for TAP addressed the support of preferential telecommunications service over IPCablecom networks. J.261 is a framework applicable to both IPCablecom and IPCablecom2 networks and forms the basis for the specifications in the new Recommendations J.262 and J.263. The framework addresses two key areas of the requirements identified in J.260: priority and authentication. Recommendation J.262 defines the specification for authentication and J.263 defines the specification for priority over IPCablecom2 networks. Future work is planned for the specifications over IPCablecom networks.

In the IPTV area, joint meetings were held with SG 16 for 2 documents addressing the interfaces between the Customer Network and Operator Network and between the Customer Network and Operations Support Systems. These interfaces are identified in J.700. These two documents are planned to be considered for consent at the next SG 9 meeting in October 2009.

Working Group 3 – Transmission of television and sound program signal for primary, secondary distribution and over optical networks, and digital program delivery controls in compressed bit streams
Chairman: Shigeyuki Sakazawa

A new study item to address the transmission system and data format to be used for free view point television (FTV) was agreed. Co-ordinating with the MPEG group any duplication in work will be addressed by the members. Work began on a new draft Recommendation J.ftvdf.

The last call comment on draft J.286, Seamless splicing for heterogeneous MPEG-2/H.264 bit streams was addressed and a revised version was produced with one remaining comment to be resolved.

Working Group 4 – Methods to deliver multi-media services over IP networks for advanced service platform and methods for conditional access against unauthorized copying and re-distribution
Chairman: Tomohiko Takahashi

A new draft Recommendation J,sdp-req, "Functional requirements for Delivery Platform for television and associated interactive services" was developed incorporating comments received during the joint Rapporteurs’ meeting with Q13/16. This Recommendation is a joint effort with WG 9. J.sdp-req was updated by including the suggestion from SG 16 to introduce a local platform on the home network to facilitate the delivery of advance applications and services by the cable operator or a third party. This recommendation is planned to be submitted for consent at the next SG 9 meeting in October 2009.

The draft will further clarify the relationship of this draft with other existing Recommendations.

Working Group 5 – Measurements and control of Quality of Service (QoS) for television transmission and objective and subjective methods for evaluating perceptual audio visual quality in multi-media services
Chairmen: David Hands and Chulhee Lee

Two new draft Recommendations J.refdef, "Perceptual video quality measurement techniques for digital cable television in the presence of a reduced reference" and J.ra-psnr, "Reference Algorithm for computing Peak Signal to Noise Ratio (PSNR) of a Processed Video Sequence with Constant Spatial Shifts and a Constant Delay" were updated and planned to be submitted for consent for the next SG 9 meeting in October 2009. J.refdef was updated by including the models from Yonsei University, NTIA and NEC as annexes. Further updates will be included for the models from Yonsei University and NEC with a functional description of the algorithm. J.ra-psnr was updated to include a proposed method for calibration sequences prior to calculating the PSNR.

The new draft Recommendation J.noref, "Perpetual video quality measurement technique for digital cable television in the absence of reference" was updated and planned for consent submission in 2010.

Working Group 6 –Work Programme, Questions, Liaisons
Chairman: Satoshi Miyaji

The work program was reviewed and revised. All liaisons addressed to the Study Group as a whole were reviewed and replies were prepared as appropriate.

Working Group 8 – Transmission of Large Screen Digital Imagery programmes for contribution and distribution purposes
Chairman: Shigeyuki Sakazawa

The group discussed the requirements for real time transmission of exLSDI and requested input from members on a system architecture utilizing existing video coding standard. This work is to be included as future Recommendation.

Working Group 9 – Functional requirements for a universal integrated receiver or set-top box for the reception of advanced content distribution services and the extension of network-based content distribution services over broadband in Home Networks
Chairman: Mayumi Matsumoto

Two new draft Recommendations J.rg-req, "A Residential Gateway Requirement to support interactive services for Hybtrid Terminal Device" and J.lasdp-req, "Functional and Application Programming Interface Requirements for Local Application and Service Delivery Platform (LASDP) for Cable Networks" were updated and further work to enhance the documents is planned before the next SG 9 meeting.
