Q. It appears that there are 5 encoded versions created, yet only 3 encoding profiles have been indicated. Does this mean that several of the encoded versions are identical, or are there only 3 encoded versions created?
A. This is overlap - 5 targets, 3 profiles. Android shares the iPhone profiles.64K AAC audio only is created dynamically by the video server.Hi 2.1 is for Mac/PC Base.3.0@ 640x360 & 3.0@ 320x180 is for iPhone & android
Q. Do you require the successful contractor to install and operate encoding facilities within your premises, the alternative being encoding in the cloud or a hybrid model? If multi-format encoding is carried out offsite, to increase upload speeds is S4C able to create a single "mezzanine" encoded file (say, at 5-10 Mbps) with equipment outside of the scope of this contract, rather than the uncompressed version used for play out?
A. We would prefer to provide a master file (suitable mezzanine level to be agreed) to the successful contractor and then for all final delivery versions to be created off site by the contractor.
Q. Within the tender document, there is reference to live streaming. Will S4C provide the live streaming encoders outside of this contract, and be responsible for delivering the appropriate live streams to the CDN? Or alternatively, is the successful tenderer responsible for providing live encoders within S4C's premises (and if so, are there any requirements such as a redundant pair, SDI input etc)?
A. S4C will provide the live streaming encoders outside of this contract, and be responsible for delivering the appropriate live streams to the CDN.
Q. Is it a correct interpretation to make, that any uploading of files (or delivery of live streams), shall be on internet circuits owned by S4C and any quality issues (in the incoming live stream/s to our CDN) or delays (inuploading source files) shall not impact on any SLAs provided by the successful tenderer?
A. Yes, this is a correct interpretation.
Q. Does S4C expect to use the live publishing points for regular or sustained periods of programming and, if so, can you provide some examples?
A. Yes both - a live publishing point is used to simulcast the transmission output. The encoder runs 24x7, but the demand fluctuates in line with the popularity of the programme being TX'ed. Occasionally we will provide an additional stream during special events such as eisteddfod, sporting events etc. (<4 times per annum). These are either long duration over approx. 1 week (e.g. Royal Welsh Show), or 2 hr instance (e.g. football match)
Q. Are the VOD services shown as CF99 and Taro 0 ever replaced by live feeds and, if so, how often and for what period?
A. CF99 and Taro 9 are available as simulcast tx and VOD.
Q. Can S4C confirm that it will take responsibility for recording live feeds for use as subsequent catch-up video files?
A. Yes, we can confirm this.
Q. Can S4C confirm what provision, if any, needs to be made for subtitles on live feeds and/or VOD files?
A. There is no current provision for subtitling on live feeds. VOD streams are available with up to 2 subtitle options (English and/or Welsh). Approx. 80% of VOD programmes have at least one subtitle option.
