杜比实验室起诉社媒平台 Snapchat 母公司，指控侵犯 AV1 与 HEVC 专利 许可管理公司 Access Advance 3月24日发布新闻稿，其合作方杜比实验室已因侵犯 AV1 与 HEVC (H.265) 专利起诉 Snap，Snap 为社交媒体平台 Snapchat 的母公司。此次诉讼标志着 Access Advance 授权方首次针对 AV1 实现提出专利主张，也是首次针对流媒体平台提出的 AV1 专利主张。尽管 AV1 常被描述为免版税视频编解码器，但 AOM 联盟及其成员并未拥有 AV1 实现中所用到的全部专利，相关 IP 仍受版权保护。杜比实验室未就其 AV1 相关专利作出任何免版税承诺。Access Advance 首席执行官 Peter Moller 强调，未获得适当许可使用先进技术会破坏创新框架，并呼吁尊重技术开发者的权利。IT之家 🏷#AV1#HEVC#专利 📢频道👥群组📝投稿
