Stream Processing

transcoding options zixi broadcaster can transcode a single input stream using multiple profiles the transcoder supports the following options video decoding – mpeg2, h 264/avc, h 265/hevc, raw video encoding – mpeg2, h 264/avc, h 265/hevc, raw audio decoding – aac, mpeg 1 audio layer i / ii / iii, mpeg 2 audio layer i / ii / iii, ac 3 (dolby digital), opus for ac 3, which can contain up to six discrete channels of sound, the transcoder only supports the left and right channels and will ignore the other channels audio encoding – aac, aac he (high efficiency) and aac hev2; pass through (no encoding) – any audio codec (mpeg1/2 / aac / ac 3, e ac 3 (dolby digital plus), opus recording options live stream inputs can be stored as mpeg ts files to a local disk drive or mounted drive multicast options multicast streams can be received or be sent by the zixi broadcaster zixi broadcaster serves as a gateway between unicast and multicast streams, while allowing reliable streaming over multicast adaptive options zixi broadcaster can create an adaptive group, subsequently editing, recording, or playing it in conjunction with dash, hls, hds or zixi you can also set a pre roll video/screen that will be played before the live streaming begins vod options zixi broadcaster supports vod (video on demand) playback of stored files in multiple formats such as ts, mp4, hls, flv billing codes billing codes are used to identify and differentiate traffic on a zixi broadcaster a billing code can be added to sources, which represent inputs to a broadcaster, and to targets, which represent outputs from a broadcaster when a billing code is added to a source or target, zixi can track the traffic on that broadcaster input or output separately from other inputs and outputs on the same broadcaster typical use cases for using billing codes are differentiating between clients if you are receiving video content from different contributing clients or sending video content to multiple external organizations, you can designate distinct billing codes for each of your clients you can then assign the client’s billing code to each source or target associated with that client your organization will then be able to bill each of their clients according to their usage charging only for billable usage when zixi traffic is sent between distinct organizations, situations may arise in which the usage of only one of those organizations is billable for example, if the contributor is using a zixi broadcaster to send outputs as if it were zec, then only the receiving organization should be billed for that traffic in that case, the receiving organization can request a billing code and assign it to their targets they can then ask the contributor to assign the identical billing code to each of the sources that they are sending in this way, zixi will know to bill only the organization that is receiving the traffic billing codes are created by zixi personnel on the zixi customer portal for a particular organization zixi can create multiple billing codes for an organization, enabling them to apply different codes to different traffic all billing codes are password protected if you would like to use billing codes in your workflows, please discuss it with your zixi representative adding a billing code to a stream will not restart the stream
