ASSESSMENT SCOPE

What this score covers

All included contribution titles and notes are available in English. The complete original text remains available in Chinese; both editions use the same scores and source links.

Uncovered contributions and unresolved harms are not treated as zero. This is not a complete assessment of a lifetime.

2 included contributions have incomplete evidence; the relevant gap appears with that contribution.

Original scope note

This research record currently includes 2 outcomes within a limited scope; M and attribution shares are revisable judgments. Uncovered content and negative effects not yet clarified are not treated as zero; specific gaps appear in the item-by-item explanations.

Original Chinese scope

本轮当前已列2项有限研究账；M与归功份额为可修订判断。未覆盖内容和未核清的负面作用不按零处理，具体缺口见逐项说明。

CALCULATION

How the score is calculated

Q = 10^(M/2) − 1; Lᵢ = aᵢ × Qᵢ; L = Σ Lᵢ; S = 2 × log₁₀(1 + L).

M is an outcome’s assessed magnitude and a is the person’s allocated share. A standalone score is only a per-item reference; the attributed light from distinct contributions is what can be combined.

M is the assessed magnitude of an outcome; attribution is the person’s share of credit. Attributed light can be added. The standalone score is only a per-item reference and must not be added across rows.

Record year1988–at least 2018

Original Chinese · record year

1988–至少2018

summaryIt continually organised requirements, competing proposals, validation tests, and international voting into interoperable families of audio-video coding standards.

Original Chinese · summary

持续把需求、竞争提案、验证测试和国际投票组织成互操作的音视频编码标准族。

M rationaleAfter expansion from early standards to later cross-institutional specification delivery, M6.4 is provisionally assigned for continuous standardisation-coordination service over thirty years; it does not aggregate by the number of standard versions, nor does it further discount outcome M because an individual's role was small.

Original Chinese · M rationale

由早期标准扩至后期跨机构规范交付后，按连续三十年标准化协调服务暂估M6.4；不按标准版本数加总，也不因个人角色小再折扣成果M。

overlap boundaryThis counts evidenced convening and specification collaboration for MPEG audio-video standards from 1988 through at least 2018, covering MPEG-1/2/4 and related later deliverables such as HEVC and MPEG-H; HEVC was work by a joint MPEG and ITU team and is not credited as the chair's personal technical invention. Market returns and the value of all coding algorithms are not fed back in.

Original Chinese · overlap boundary

计1988起至至少2018有证的MPEG音视频标准召集与规范协作，覆盖MPEG-1/2/4及后期HEVC、MPEG-H等相关交付；HEVC为MPEG与ITU联合团队工作，不归主席个人技术发明。市场收益和全部编码算法价值不回灌。

Evidence gapsIndividual technical proposals have not been verified standard by standard; licensing and net market consequences are not closed; later scope was added from official-index excerpts, departure from office in 2020 has not been closed by the original official page in this work, and actual division of labour specification by specification still needs supplementation.

Original Chinese · evidence gaps

未逐标准核个人技术提案；许可与市场净后果未闭合；后期范围由官方索引摘录补入，2020卸任尚未由本次官方原页闭合；逐规范实际分工仍待补。

约1996–2004

summaryIt organised the standardisation problem from 'compressed bits' outward to describing content and a multimedia framework across stages.

Original Chinese · summary

组织从“压缩比特”扩展到描述内容与跨环节多媒体框架的标准化问题。

M rationaleFormal specifications for content description, digital objects, and rights expression are knowledge and negotiated outcomes distinct from compression coding; on an estimate of their limited value in organising interoperability, direct costs of licensing constraints and standard fragmentation are included, and adoption scale or the original technical inventions are not credited to the chair.

Original Chinese · M rationale

内容描述、数字对象与权利表达的形式规范属于区别于压缩编码的知识和协商成果；按其有限互操作组织价值估计，许可限制与标准碎片化的直接代价纳入，不把采用规模或原技术发明归主持人。

overlap boundaryOnly the independent specification residual of MPEG-7 content description and the MPEG-21 multimedia framework relative to coding standards is counted; it is not credited with all search, DRM, or content platforms.

Original Chinese · overlap boundary

只计MPEG-7内容描述和MPEG-21多媒体框架相对编码标准的独立规范残余；不领取所有搜索、DRM或内容平台。

Evidence gapsThere is no item-by-item textual evidence for personal technical contributions; the net effects of MPEG-21 rights and interoperability remain to be checked.
