Real-time processing of 3G-SDI signals
API to access video, audio and ANC data
Bi-level and tri-level genlock input portI
Description
FEATURES
- Two ports fully configurable in software:
– Input or output
– 3G-SDI, HD-SDI, SD-SDI or DVB-ASI
– 3G-SDI ports can be configured to operate in level A or level B mode - Bi-level and tri-level genlock input port
- Low latency to and from software
- Sophisticated DMA engine
- DekTec Matrix API 2.0 provide convenient access to video, audio and ANC samples, and takes care of all the plumbing for creating robust real-time SDI processing applications.
- Free SDK (DTAPI) for Windows and Linux
APPLICATIONS
- Generation, reception and processing of uncompressed or compressed streams.
- General purpose processing of a mix of 3G-SDI, HD-SDI and/or ASI signals
- Video encoding or decoding
- Audio insertion or extraction
- Live production mixer and effect generators
- SDI monitoring, recording and/or play-out
DekTec Matrix API 2.0
The Matrix-API framework decodes incoming SDI data into pixels (in a programmable format), audio samples and ANC data structures. When a new frame has been received, the framework calls a user-supplied “frame-processor callback” for processing of the data. The user callback can create output video, audio and ANC data, which is encoded by the framework into SDI frames.
Synchronization of multiple input streams is straightforward: The video/audio/anc data of all SDI frames supplied to the callback function have the same arrival time by definition. Past frames can be accessed by an integer frame index. The framework ensures that if frames from different input ports have the same frame index, they have entered the system at the same time instance.
