57
-[JPEGXS](https://jpeg.org/jpegxs/) ([Specification](https://ds.jpeg.org/whitepapers/jpeg-xs-whitepaper.pdf)) - The JPEG XS (ISO/IEC 21122) standard specifies a compression technology with an end-to-end latency of a few lines, at a low implementation complexity.

### Transport Streams
64
+
#### CBR
65
+
#### Piecewise VBR
66
+
A piecewise constant VBR transport stream can only vary at the PCRs of the program under consideration per ISO/IEC 13818-1:2007 § 2.4.2.2.
67
+
#### Non-piecewise VBR:
68
+
A non-piecewise constant VBR transport stream has no predictable time base to reconstruct the signal if the inter-packet timing is altered in transit through the network.

## High Bit Rate Media Transport (HBRMT)
70
+
> Formerly known as High Bit Rate Audio Video Over IP (HBRAV-IP)
47
71
72
+
Standard for data encapsulation and forward error correction (FEC) of high bit rate contribution oriented video/audio feed services, up to 3 Gbit/s over Ethernet networks. HBRMT is published as parts 5 and 6 of SMPTE 2022 by the [SMPTE 32NF networking technology committee](https://web.archive.org/web/20110125153532/http://www.videoservicesforum.org/SMPTE_32NF_Tech_Com.shtml). HBRMT supports both SDI uncompressed and JPEG 2000 compressed video and audio formats.

### [ST 2022-1:2007 “Forward Error Correction for Real-Time Video/Audio Transport Over IP Networks”](https://ieeexplore.ieee.org/document/7291470)
29
+
Defines a forward error correction technique for the carriage of real-time Video/Audio content over IP networks. <details><summary>Rough Explanation</summary>_Defines row/column FEC (Forward Error Correction) for IP video streams. Along with Section 2, this standard has been widely implemented. Row/Column FEC works by grouping IP video packets into logical rows and columns, and then appending one FEC packet to each row and each column.[[1]](https://web.archive.org/web/20151208160422/http://www.tvtechnology.com/insight/0083/smpte--and-the-future-of-video-over-ip/220188)_</details>

Defines a unidirectional transport protocol for the carriage of real-time [_Constant Bitrate (CBR)_](/README.md#cbr) MPEG-2 Transport Streams over IP networks. <details><summary>Rough Explanation</summary>_Specifies how constant bit rate compressed video signals that are encoded within MPEG-2 transport streams are encapsulated into IP packets. This standard covers the transport layer (RTP and UDP) as well as comments about timing and buffer sizes.[[1]](https://web.archive.org/web/20151208160422/http://www.tvtechnology.com/insight/0083/smpte--and-the-future-of-video-over-ip/220188)_</details>

Defines a transport protocol for the carriage of real-time [_piecewise constant variable bit rate (VBR)_](/README.md#piecewise-vbr) MPEG-2 Transport Streams over IP networks, either with or without Forward Error Correction for recovery from network transmission errors. <details><summary>Rough Explanation</summary>_Defines IP packets for variable bit-rate MPEG-2 TS streams that are constrained to have a constant bit rate between PCR messages (called piecewise-constant).[[1]](https://web.archive.org/web/20151208160422/http://www.tvtechnology.com/insight/0083/smpte--and-the-future-of-video-over-ip/220188)_</details>

Defines a transport protocol for the carriage of real-time [_non-piecewise constant variable bit rate (VBR)_](/README.md#non-piecewise-vbr) MPEG-2 Transport Streams over IP networks, either with or without Forward Error Correction for recovery from network transmission errors. <details><summary>Rough Explanation</summary>_Similar to Section 3, except that it removes the constraint on bit rates.[[1]](https://web.archive.org/web/20151208160422/http://www.tvtechnology.com/insight/0083/smpte--and-the-future-of-video-over-ip/220188)_</details>

### [ST 2022-5:2012 “Forward Error Correction for High Bit Rate Media Transport Over IP Networks”](https://ieeexplore.ieee.org/document/7291908)
41
+
Defines a forward error correction technique for the carriage of High Bit Rate real-time media over IP networks. <details><summary>Rough Explanation</summary>_Expands on Section 1 to allow larger row/column FEC combinations to support signals with bit rates up to 3 Gbps and beyond.[[1]](https://web.archive.org/web/20151208160422/http://www.tvtechnology.com/insight/0083/smpte--and-the-future-of-video-over-ip/220188)_</details>

47

Defines a unidirectional IP-based protocol for the transport of real-time video, audio, and ancillary signals. <details><summary>Rough Explanation</summary>_Specifies a way to transport high bit-rate signals (including uncompressed 3 Gbps 1080p video) that are not encapsulated in MPEG-2 transport streams.[[1]](https://web.archive.org/web/20151208160422/http://www.tvtechnology.com/insight/0083/smpte--and-the-future-of-video-over-ip/220188)_</details>

50
+
Defines requirements for redundant streams of SMPTE 2022 packets to allow for creation of a single reconstructed output stream through seamless protection switching at the RTP datagram level. <details><summary>Rough Explanation</summary>_Describes a way to send two matching streams of packets from a source to a destination over different paths, and have the receiver switch automatically between them. This allows a perfect video signal to be reconstructed at the receiver as long as both paths do not fail simultaneously.[[1]](https://web.archive.org/web/20151208160422/http://www.tvtechnology.com/insight/0083/smpte--and-the-future-of-video-over-ip/220188)_</details>

Specifies the use and constraints for SMPTE ST 2022-6 streams in conjunction with the timing model of SMPTE ST 2110-10, including definition of a Synchronizing Timestamp derived in the ST 2022-8 receiver to relate the two standards. It also documents the SDP announcement of SMPTE ST 2022-5 FEC and SMPTE ST 2022-7 redundancy for these streams. <details><summary>Rough Explanation</summary>_TODO_</details>
