Highest image quality for a premium On Demand TV service

A global broadcaster chooses Quasar XF to seamlessly deliver premium content via their On Demand TV service. They have a number of SD and HD interlaced files in 525 59i and 1080 59i which need converting to 720 59p.

Such format conversion relies on a two stage process, deinterlacing followed by image scaling. Low quality deinterlacing can introduce unwanted artifacts such as jaggies and tearing, and suffer from loss of vertical resolution on both static and moving regions.

To stay ahead of rival broadcasters and protect their brand value, they are seeking a competitive edge in the image quality of their premium On Demand service. Using Quasar XF, the broadcaster has confidence that they will deliver pristine picture quality for their audience, regardless of the format of the incoming content source.

Offering the highest image quality regardless of the content source.

Designed as an integral part of the xFile framework, Quasar XF scales from the smallest installation to multi-licence systems allowing them to evolve their installation around their needs.

HD down-conversion

Delivering uncompromised results first time, every time

A playout service provider relies on Quasar XF for their down conversion from HD to SD for terrestrial transmission. They have a large number of HD assets in 1080 50i which need converting to 625 50i.

Such down conversion relies on deinterlacing and carefully optimised down conversion apertures. Poor quality down conversion will result in unwanted artefacts such as vertical and horizontal aliasing.

This aliasing occurs when the high frequency source content is not managed correctly during the spatial down sizing. The lower spatial sampling frequency of the SD output cannot faithfully represent all the frequency range present in the source. Quasar XF offers the maximum possible resolution whilst removing unwanted aliases ensuring the very best image quality, first time, every time.

Adding to its uncompromised quality, Quasar XF offers simple integration using a Service Orientated Architecture (SOA) approach in accordance to the standardized FIMS (Framework of Interoperable Media Services) SOAP (Simple Object Access Protocal) interface.

1080i up-conversion to 4K

Delivering outstanding images to the savvy viewer

A UK post production facility has been asked to edit and produce a 4K master of premium content within a very tight deadline. Not all the content was captured at 4K so they need to up-convert the 1080 50i to 4K 50p.

Such up-conversion relies on a two stage process, deinterlacing followed by image scaling. Low quality deinterlacing can introduce unwanted artifacts such as jaggies and tearing, and suffer from loss of vertical resolution on both static and moving regions.

The expectations of the viewing experience at 4K 50p are high and demand the very best up-conversion quality. The 4K screen reveals finer detail, greater texture, and astonishing emulsion of smoothness, thus any artefacts will be magnified and are unacceptable.

Quasar XF brings unrivalled intelligent adaptive format conversion into your facility.

Using SAM’s intelligent adaptive de-interlacing technology, Quasar XF delivers maximized vertical resolution for all types of content. Since Quasar XF can be seamlessly integrated in any workflow via nominated watch folders, conversion can be performed 24/7, enabling efficient use of all valuable processing assets. 

This allows the facility to convert all content with confidence, delivering best quality end result to their customer in a timely manner.
