Telestream Lightspeed

Transcoding @ Lightspeed

A family of pocket-sized and low-cost optical light sources for the installation and maintenance of singlemode and multimode fiber optic networks.

Telestream® G6 Lightspeed™ Server can be added to any Vantage Transcode product or Post Producer to accelerate video processing and H.264 transcoding. Lightspeed Server accelerates video processing with GPUs and multicore CPUs to provide the best image quality in the least amount of time. Housed in an efficient 1 RU chassis, Lightspeed G6 Servers reduce rack space, power and cooling requirements while meeting increased output capacity needs.

Accelerated Video Processing

The G6 Lightspeed is a dual-GPU NVIDIA Pascal-based server that accelerates compute-intensive image processing within Vantage workflows, including scaling, deinterlacing, frame rate conversion, motion vector calculation, and other tasks that require computation and analysis to modify or create new video frames. Faster video preprocessing acceleration benefits the output quality of all video output formats, for both transcoding and automated content assembly.

Deinterlacing

Deinterlacing is required when converting interlaced broadcast content for web and mobile distribution and is also the first step in high-quality frame rate conversion. High-quality deinterlacing produces far sharper and clearer image quality than is possible with simple field blending techniques.

Video Image Scaling

Advanced image scaling is crucial to maintaining high-quality results. Both up-scaling and down-scaling require significant processing to preserve image sharpness. Lightspeed image scaling eliminates banding and ringing artifacts that are associated with video upconversion. This is particularly useful when converting broadcast content into web and mobile formats.

Frame Rate Conversion

Frame rate conversion is increasingly important for internationalization and inverse telecine workflows. Lightspeed accelerates both standards conversion and the conversion of broadcast content to 23.976 film rates, with reliable, high-quality results.

16-bit YUV Video Processing

Vantage employs Lightspeed technology to efficiently process 16-bit, 4:4:4:4, YUV video, achieving sparkling video quality and color fidelity for any Vantage output format. Lightspeed accelerates sophisticated image processing algorithms that have previously required purpose-built hardware to produce pristine video.

Accelerated x264 Encoding

Lightspeed Server also speeds x264 video encoding. x264 is renowned for producing the best video image quality across the spectrum of bitrates needed for screens of any size. Lightspeed accelerates x264 to produce the best possible H.264 images, at any bitrate, in the shortest possible time.

Accelerated HEVC Encoding

The G6 Lightspeed supports NVENC (NVIDIA’s HEVC Encoder) for certain Vantage transcoders, enabling encoding performance that is faster than x264 (but in most cases of lower quality).
