Bradbury Transcoder — Транскодирование, адаптивное качество изображения

Bradbury Transcoder

The Bradbury Lab company offers a unique opportunity for telecom operators and telecommunication companies for expanding the zone of services. Operator can increase a subscriber premises network and to get additional profit with Bradbury Live Streaming.

Bradbury Transcoder — the modern and effective solution for conversion of a video stream in real time and its adaptations to throughput of the channel. Solution allows to optimize image quality for any available device with continuous broadcasting on any network — from the smartphone on the EDGE network to Smart TV on Wi-Fi.

Primary
benefits

Support of a broad range of devices and permissions: from mobile to Ultra HD

Bradbury Transcoder will transform the entering flow with the big bitrate to several similar flows with smaller bitrates with minimum loss of quality. It allows to adapt quality of video and a sound for any device of the user, whether it be the smartphone or the TV set with Ultra HD the screen. At the same time doesn't matter in what point of the Internet there is a device, the user always receives content of the highest quality. This technology gives the chance to the operator to render services outside the own networks and to enlarge considerably number of subscribers.

High reliability and fail safety of a transcoder

Bradbury Transcoder possesses a coding error correction system, the clustering of management system which is responsible for condition monitoring and controls operation of a transcoder allows to provide complete fail safety. In case of refusal of main system there is an opportunity to transfer all its functions to adjacent machines in a cluster that does any failures in system imperceptible for the subscriber. In the same moment, the System administrator receives the notification message with specifying of detailed data on incident.

Additional
opportunities

Flexible and scalable solution

Bradbury Transcoder is easily extends and scales together with the extends of a subscriber premises network of the operator and the number of the broadcast channels. Manual and automatic balancing of loading with a possibility of placement into several tens of servers in one failover cluster guarantees high reliability and a quick response of system
High efficiency and economy

With the Bradbury Lab operators have an opportunity to place twice more channels into a rack-mount unit in comparison with solutions of other companies, thereby having cut down expenses on acquisition, placement and support of the equipment.
compliance with modern standards

Transcoding is made on the basis of the modern compression standards of video H.264/AVC and H.265/HEVC, for achievement more high compression ratio of a video stream when saving the maximum image quality. This technology allows to cut bandpass range for video transmission by about in 2-4 times in comparison with the analogs which are available in the market.

Bradbury Transcoder in the shortest times is deploy in the existing infrastructure thanks to hardware compatibility with the equipment of HP, IBM, Cisco, etc., and also integrations with main systems of protection of content (Widevine, Verimatrix) by means of the universal interfaces (API) "out of the box".
Intuitive interface

Simple and available process control of transcoding. Setup of system is available from any browser and allows to control video/audio of compression parameters, balancing of loading, to track operability of system, and to configure monitoring settings.
Hybridity, universality of the solution

With Bradbury Transcoder the telecom operators can take on the new level of development of technologies of interactive television from IPTV to OTT, provide more of wide range of services outside the own networks. The decision allows to render the services IPTV and OTT from a uniform complex of broadcasting without the need for purchase of the additional equipment.

60 clusters of transcoding for
Rostelecom

For implementation of this task our company successfully installed system of transcoding of TV-channels on the data communication network of Rostelecom. We participated in the scale project of federal level, to expand significantly a zone of providing of services of "Interactive TV" in all territory of the country. As a result, the installed system of transcoding drastically reduce the workload into the HD channels broadcast of a data communication network of Rostelecom. The subscribers of HDTV which connected on xDSL technology has the opportunity to watch the high definition television. The service was unavailable to them before due to low speed access to service on "the last mile".

Hybrid TV
MTS

The hybrid TV-solution at the programming layer will connect cable television of the IPTV standard on the basis of a network of MGTS in Moscow and DVB-C in regions of Russia, and also MTS satellite television with online services. Among them a program guide with expanded functions, video on demand and service of the postponed viewing.

Hybrid MTS TV also offers subscribers the "smart set-top boxes" developed especially for the operator, which openes access on the TV screen to the interactive program of telecasts, exchange rates, road condition and news feeds. The set-top box can be connected to the home Internet and subscribers gain access to additional services — the postponed viewing (Catch-up TV), to video on demand (VOD), and to function of a pause (TimeShift).

Our company participates in the project by offer the following products: system of transcoding, record and broadcasting, CDN-network of delivery of a video content. Implementation takes place at the federal level and the number of the cities where nodes of CDN are set, permanently.

System of transcoding of
IPTV of ER-Telecom

The primary purpose of the project was implementation of transcoding HD channels for the platform Dom.ru TV. Transcoders from the Bradbury Lab became a good addition to the existing components of the platform and have allowed service subscribers of Dom.ru utilize the content in the HD-quality with minimal load of bandwidth network of the telecom operator.
