1 SelenioFlex File Application: Editor Workflow Workflow driven by the offline editor, exporting reference file into watch folder SelenioFlex File accesses referenced files directly from SAN/NAS o Very high quality deinterlacing and inverse telecine during pre-processing, encoding to multiple ABR delivery formats (including remuxing of common encode layers) o Output ABR formats include various caption, subtitle and DRM options o Outputs automatically uploaded via FTP or HTTP, and notification sent Watch Folder Offline Editor ABR Outputs FTP/HTTP Notification Apple Final Cut Pro, Avid MediaComposer, Adobe Premiere QuickTime reference files can be used, eliminating need for long rendering/mixdown processing on editor machine Files can be read directly from NAS/SAN, eliminating need to copy source files to encoder Decode native editing format (ProRes, HDV, DNxHD, XDCAM, etc.) High-quality motion-adaptive deinterlacing with frame-rate conversion Configurable multilayer HLS, Microsoft IIS Smooth Streaming, MPEG-DASH (supporting H.264, AAC, Dolby Digital Plus, DTS Express) Embedded caption (EIA-608/EIA-708) support TTML (SMPTE TT, DFXP) generation per SMPTE RP2052 DRM support (SecureMedia and Verimatrix with HLS; Irdeto with PlayReady) Automatically sends resulting ABR files via FTP and HTTP When job is complete (successfully or not), an is automatically sent to various recipients (rules-based configurable depending upon nature of completion)

2 SelenioFlex File Application: DAI (for SCTE130) Workflow Process creates edit decision list (EDL), incorporating lead-in, promos and main asset all stored in SAN storage During encoding, the output is conditioned for down-stream ad insertion; an ESAM communication is made to placement opportunity information service, where SCTE35 cue points are identified, and encoder boundary point (EBP) markers are inserted Resulting files can be used by down-stream packager for just-in-time packaging POIS DAI TS Outputs Packager Web Services (SOAP) API with multiple asset management systems theplatform, Ericsson CMS, Sony MediaBackbone, Contentbridge, etc.) EDL is generated allowing user to mark in/out trim points of multiple separate audio/video Any variable in the blueprint can be changed dynamically at runtime via the API Decode broadcast server format (LXF, GXF, MXF) directly from storage Trim multiple source files and stitch together using EDL Captions and timecode extracted from embedded ancillary data produces HD and SD frame-sizes ESAM (IO3) Encoder Boundary Point insertion (EBP) SCTE35 insertion in private data PID IDR frames triggered at ad placement points ATS conditioned H.264/TS output files Down-stream packagers such as RGB, Cisco, Envivio

3 SelenioFlex File Application: VOD Workflow Process creates edit decision list (EDL), incorporating lead-in, promos and main asset all stored in SAN storage Various graphic and video overlays are key-framed at times specified via API Output is HD and SD Cablelabs files, including retimed captions Broadcast Server Storage (connected to SAN) Overlays VOD (CableLabs) Deliver to MSO Web Services (SOAP) API with multiple asset management systems theplatform, Ericsson CMS, Sony MediaBackbone, Contentbridge, etc.) EDL is generated allowing user to mark in/out trim points of multiple separate audio/video Any variable in the blueprint can be changed dynamically at runtime via the API Decode broadcast server format (LXF, GXF, MXF) directly from storage Trim multiple source files and stitch together using EDL Captions and timecode extracted from embedded ancillary data produces HD and SD frame-sizes Key-framed graphic overlays (bugs) dynamically overlaid, including fade-in/out with multiple transition curves (step, ease-in, ease-out, etc.); support for multiple file-types including JPG, BMP, PNG, TIFF Key-framed video overlays ( e.g. motion snipes, lower-thirds), including support for alpha channel blending HD and SD H.264 video encoding, Dolby Digital audio encoding, multiplexed into MPEG2 Transport Stream (CableLabs 3.0 compliant) Support for EIA-608 caption retiming (e.g. original captions at can be retimed to , 29.97)

4 SelenioFlex File Application: Pass-Through Workflow Media file (e.g., transport stream) is demultiplexed; video is passed-through untouched, audio transcoded into new format (e.g., Dolby Digital Plus) Separate caption file is referenced in API call, and encoded into compliant TTML outputs All resulting streams are muxed into Microsoft IIS Smooth Streaming output H.264 ES (Demuxed) TS File Source Media File Demultiplex Decoded Audo DD+ Web Services (SOAP) API with multiple asset management systems theplatform, Ericsson CMS, Sony MediaBackbone, Contentbridge, etc.) SCC File Source Caption File Decoded EIA-608 Captions Dolby Digital Plus Audio Encoder TTML Subtitle Encoder TTML Subtitles Smooth Streaming Package Multiple Files (media file and caption file) H.264 compressed stream is passed through without decoding Audio is transcoded from Dolby Digital AC3 to Dolby Digital Plus (EAC3) Smooth Streaming output combines audio, video, and caption (TTML subtitles) into a single deliverable EIA-608 captions converted into TTML (SMPTE TT/DFXP) per SMPTE RP2052

5 SelenioFlex File Application: Studio XDCAM Distribution Workflow Workflow driven by watch folder via XML SelenioFlex File generates a head-roll based on XML submission to precede main content; this contains text to be overlaid as a slate Single input is then converted into various output formats, including SD NTSC and PAL and HD NTSC and PAL (various processing options used, including 3:2 pulldown, speed-up, and optionally motion-compensated standards conversion) Multiple XDCAM output files are encoded, followed by automatic QA via integrated third-party QC tool providers XDCAM (NTSC SD) XDCAM (PAL SD) Slate Generation XDCAM HD (NTSC HD) Auto QC Contribution format and archive format 10-bit lossless JPEG2000 in MXF 10-bit uncompressed AVI XDCAM HD (PAL HD) TektronixCerify, Interra Baton, Vidcheck integrated for automatic QC process Separate wave files for multiple audio Build slate, black and silence for predetermined head-roll Overlay slate text (programmatically submitted via XML submission) Decode file at Perform 3:2 pulldown to 29.97fps (NTSC) Perform audio/video speed-up to 25fps (PAL) Scale for SD PAL/NTSC Multiple XDCAM deliverables covering multiple markets Generate LTC and VITC timecode 16-bit video bit depth processing pipeline Full-range to headrange conversion (broadcast-safe)
