新编解码器的主要重点是 技术建议TR-07从 视频服务论坛（VSF是JPEG XS。新的编解码器是真正专门用于高质量和非常低的延迟，并侧重于 高质量的live 视频贡献和传输.
通过TR-07，JPEG XS互操作性活动小组专注于 JPEG XS over MPEG-2 TS使用SMPTE ST 2022-2来确保互操作性.VSF TR-07沿用了在MPEG-2 TS中已经完成的内容。 JPEG 2000 VSF TR01我们使用ST 2022-2作为MPEG-2 TS中的IP 封装机制。在MPEG-2 TS封装中，我们有JPEG XS编码流，用于视频以及音频和辅助数据。TR-07是专门针对广域网（WAN）的。
More and more applications, such as camera control, need super-low latency. At the same time, live production has become more popular. Humans can get used to some latency, but the lower the latency is, the easier it is to deal with it.
With JPEG XS, compared to the previous JPEG 2000, we are talking about 1- to 3-millisecond latency versus 100 milliseconds with JPEG 2000. This really gives the feeling to the technical staff and operators that there is no latency at all and that they can do everything as if they were there! These are the benefits of JPEG XS: very minimal latency, very high-quality for supporting remote production. JPEG XS is the new ISO/IEC standard 21122, designed for latency-critical real-time applications and offering near-lossless and visually lossless quality with low power and low complexity.
简而言之，VSF TR-07的工作包括
简而言之，VSF TR-07的工作包括
• 广域网（WAN）SMPTE 2022-2封装方式
• JPEG XS 444.12 High Profile主要侧重于4:2:2的互操作性点。
• 编码效率的范围约为1.5至4每像素位数(bpp)
• 具有互操作点组的互操作能力集
• 高清、4K和8K电视格式/帧率能力集，包括HDR和WCG• 音频和辅助数据支持
VSF TR-07将视频格式分为能力集，这意味着供应商可以通过说明其可以处理的子集来遵守该规范。运行 JPEG XS over MPEG2 Transport Stream定义了2K、4K和8K视频的能力，无论是否有HDR。JPEG XS的压缩不是针对音频，而是针对视频。因此，我们可以使用MPEG-2 TS的一部分，以标准化的方式将JPEG XS基本流（ES）和AES音频复用到一个MPEG-2 TS中。VSF TR-07 MPEG-2 TS规范涵盖了除了压缩以外的各种内容。
VSF成员旨在为使用JPEG XS进行高质量视频传输的发送方和接收方创造全行业的兼容性。它是促进live 工作流程、非物质化设施或基于cloud 操作的互操作性的标准方式。intoPIX 提出了基本的传输解决方案，可以在局域网、广域网或进入 在局域网内，通过广域网或进入Cloud.
“JPEG XS is the new SDI” supported by both ST2110-22 (VSF TR-08) and ST2022-2 (VSF TR-07) and effectively bridging both LAN and WAN-based workflows. VSF has also released the new TR-08, which can be used for LAN but also for WAN and cloud applications, supporting the transport of JPEG XS Video in ST 2110-22. intoPIX has also released a free Wireshark VSF TR07 Dissector for JPEG XS in MPEG-TS
