SMPTE® ST2110 standard compatible streaming software
*M2S SDK・・・Macnica Media Streaming SDK
1. Overview
The number of broadcast station facilities using IP is increasing both in Japan and overseas, and IP-based systems have evolved to a level of maturity that is always the basis for consideration when renewing facilities.
After advancing one stage, the next thing is not only to replace SDI with IP, but also to enjoy more of the benefits of IP. Furthermore, as a vision for the future, we are beginning to see the point of moving broadcasting equipment to the cloud.
In order to realize these, we provide SDK (Macnica Media Streaming SDK) that operates on general-purpose server equipment and enables function implementation for broadcasting equipment with "software".
2. Features
◇ Compliant with SMPTE ® ST2110 standard and AMWA NMOS IS-04, IS-05
- Supports Video (4K,1080p,1080i / 50Hz, 59.94Hz / 4:2:2 / 10bit), Audio (24bit / 2 to 32ch), Ancillary
- Compatible with ST2110-22. JPEG-XS encoding and decoding will be supported by hardware processing or software processing using CPU or GPU
◇ Provide API with M2S SDK
- Controllable by API. Since the basic processing of ST2110 such as generation and analysis of various IP packets and hitless protection is performed inside M2S,
Customers can focus on video, audio and ancillary raw data processing and application development
◇ Supports multiple NICs
- API can be used in common with NIC
◇ Supports PTP control by Hardware Timestamp on NIC
◇ GPU compatible
- When using with a GPU installed, load-intensive processing is performed by the GPU, reducing the load on the CPU.
◇ Compatible with Linux OS (Ubuntu)
- Plan to support Windows
◇ Provides ST2110 plug-in for GStreamer that supports M2S
- By connecting GStreamer elements, it is possible to input and display video and audio, and transmit ST2110 compressed content.
- Can be input to OBS Studio by concatenating with v4l2 elements
