Viz One - Publisher 2.5

These release notes cover both versions 2.3, 2.4 and 2.5.

These release notes cover both versions 2.3, 2.4 and 2.5. Version 2.3 was a feature release with Akamai HLS, still images overlays and mpeg2 transport stream parameter control. Version 2.4 was a feature release with multiple layers of Vizrt graphics, secure streaming, Akamai RTSP, and fast and simple RPM-based installation. Version 2.5 was a feature release for closed captioning support.

New features

  • Multiple layers of Vizrt Graphics  – When adding graphics to VOD assets using the Viz Engine, it is now possible to add several scenes to the same part of a video, e.g., a lower 3, a map, and an over-the shoulder together with a logo or a courtesy field. Different graphics layers are used to control the z-orientation of the different graphics elements if the graphics are used in the same screen position. This gives significantly more freedom in determining the timing and placement of graphics and allows for more complex graphics. The setup consists of a standard Online VOD package combined with one or more Viz Engines. The setup can be scaled to achieve real-time speed for both video and graphics processing.
  • Closed Caption Support  - It is now possible to add sidecar files with closed captioning to Digital Items. During transcoding the profile specifies whether closed captioning should be embedded and in what format or if it should be burned-in. We support WebVTT, SRT, SSA and CEA-608 caption formats.
  • Akamai Support  - It is now possible to connect an Akamai CDN as an extension to Viz One. Both RTSP and HLS streaming protocols can be connected for high volume video distribution. HLS streams are forwarded to Akamai using HTTP Post.  The support includes use of the Akamai token authorization when publishing HLS streams to the Akamai Live HLS Origin Server. This will automatically be enabled and applied for content published in restricted mode on theViz OneOnline server when published to a configured Akamai Live HLS Origin Server.
  • Viz Reporter for Android – A new version of Viz Reporter for Android is now available for file uploads from Android 4.x phones. The application supports upload of audio- and video files and metadata in the very robust and stubborn upload protocol. The application is hosted on the Google Play store. The existing iOS version is available in the Apple App Store.
  • Logo Insertion/Still Image Overlay – For VOD content it is now possible to insert device-adapted logos on the transcoded material. This is achieved by referring to PNG images containing the logo and associated timing information when a video is ingested. The images are overlaid on the video during transcoding from the specified start and duration times for the overlay without adding extra time to the transcode process. Logo insertion can also be combined with Vizrt Graphics.
  • Fast and Simple RPM-based Installation - The new installer uses RPMs for significantly faster and simpler software installation and maintenance.
  • Device Detection Fallbacks - Some classes of devices can still play video even though the exact device is not in the device database. Most noteworthy this applies to Android and Windows Phone devices.
  • Secure Streaming via AES-128 encryption - It is now possible to encrypt the HLS video TS-segments using AES 128-bit for secure streaming. AES-128-bit is natively supported on iOS. The key can be maintained through the API for the user of the API to control the key store.
  • Brightcove Support – Content can now be delivered through the Brightcove video player. Viz One will register videos in the Brightcove API and deliver the Brightcove media IDs from our API. Please note that setup typically requires some professional services.

Additional High-level Features

  • Simple Filename Rules - This allows controlling the file names that are used during publishing based on simple rules and item metadata.
  • Mpeg2 Transport Stream Parameter Control - Added support for controlling certain aspects of mpeg2 transport streams. Examples include parameters such as; pmt, audio and video PIDs, mux rate, maximum PCR-pts difference and vbv size.
  • Simplified Media Consumption - It is now possible to consume a specific transcoded video given the ID of the Digital Item it belongs to and the ID of the media resource
  • Viz Reporter Playout Control - It is now possible to set Viz Reporter live session to automatically start/stop playing on a specified Playout Server and SDI connector.
  • Updated Transcoding Profiles – Updated transcoding profiles are shipped to support the updated set of devices out in the market and to support the HTML5 video developments.
  • Updated Stream AuthenticationThe updated authentication module for RTSP-, RTMP- and HTTP streaming servers giving better performance, flexibility and stability.
  • Improved Broadcast Video Format – Ingest and output of new broadcast codecs has now been added together with improved transcoding speed for these formats.
  • Improved Live Encoding Quality – New h.264 codec library provides improved CPU utilization and video quality for VOD and Live content.
  • Improved HTML5 Video Quality – New codec library for webm provides improved CPU utilization and video quality for VOD content.
  • Several Bug Fixes for the RTSP Streaming Server – Important bug fixes for the RTSP streaming server have been implemented and will ensure improved streaming server stability.
