Quick Reference Guide To: How to Deliver Content to ITV Your Programme Has Been Commissioned and You Have Been Asked by ITV to Deliver a Piece of Content
July 2020 Quick Reference Guide To: How to Deliver Content to ITV Your programme has been commissioned and you have been asked by ITV to deliver a piece of content. What do you need to do and who are the contacts along the journey?..... Firstly, you will need to know who your Compliance Advisor is. If you’ve not been provided with a contact then email [email protected]. Your Advisor will be able to provide you with legal advice along the journey and will be able to provide you with lots of key information such as your unique Production Number. Another key contact is your Commissioner. They may require some deliverables from you so it’s best to have that discussion directly with them. Within this guide you will find a list of frequently asked questions with links to more detailed documents. 1. My programme will be transmitted live. Does this make a difference? 2. My programme isn’t live; so what exactly am I delivering? 3. Where do I get my Production/Clock Numbers from? 4. Where can I get my tech spec to file deliver? 5. Where do I deliver my DPP AS-11 file to? 6. I need to ensure that my programme has the ITV ‘Look & Feel’. How do I make this happen? 7. Can I make amendments to my programme after I’ve delivered it to Content Delivery? 8. Where do I send my Post Productions Scripts to? 9. What do I do if I have queries around part durations and the total runtime of my programme? 10. -

Surround Sound Processed by Opus Codec: a Perceptual Quality Assessment
28. Konferenz Elektronische Sprachsignalverarbeitung 2017, Saarbrücken SURROUND SOUND PROCESSED BY OPUS CODEC: APERCEPTUAL QUALITY ASSESSMENT Franziska Trojahn, Martin Meszaros, Michael Maruschke and Oliver Jokisch Hochschule für Telekommunikation Leipzig, Germany [email protected] Abstract: The article describes the first perceptual quality study of 5.1 surround sound that has been processed by the Opus codec standardised by the Internet Engineering Task Force (IETF). All listening sessions with up to five subjects took place in a slightly sound absorbing laboratory – simulating living room conditions. For the assessment we conducted a Degradation Category Rating (DCR) listening- opinion test according to ITU-T P.800 recommendation with stimuli for six channels at total bitrates between 96 kbit/s and 192 kbit/s as well as hidden references. A group of 27 naive listeners compared a total of 20 sound samples. The differences between uncompressed and degraded sound samples were rated on a five-point degradation category scale resulting in Degradation Mean Opinion Score (DMOS). The overall results show that the average quality correlates with the bitrates. The quality diverges for the individual test stimuli depending on the music characteristics. Under most circumstances, a bitrate of 128 kbit/s is sufficient to achieve acceptable quality. 1 Introduction Nowadays, a high number of different speech and audio codecs are implemented in several kinds of multimedia applications; including audio / video entertainment, broadcasting and gaming. In recent years the demand for low delay and high quality audio applications, such as remote real-time jamming and cloud gaming, has been increasing. Therefore, current research objectives do not only include close to natural speech or audio quality, but also the requirements of low bitrates and a minimum latency. -

Channel 4 Playout Red Bee Media
CASE STUDY Channel 4 Playout Red Bee Media Summary Red Bee Broadcast Centre in White City, London is dedicated to providing a centralised playout facility for UK broadcasters. Custom built in 2003, its clients include the BBC and BBCHD, Channel Five, Virgin Media and Channel 4. One of the IDS displays in the new playout facility. The brief In 2009, Red Bee Media won the contract to host the playout services for Channel 4 and its family of channels including Film 4, E4 and More4. To fulfil the operational requirements, a large new central playout area was commissioned, supplemented by two reactive playout suites, each with an associated continuity booth with a third continuity booth situated outside the main area. We were asked to install an IDS system that met two main requirements: 1. Provide a visual link between network directors in the various playout positions and continuity announcers in their isolated booths. 2. Develop an IDS interface for the Snell Morpheus automation system to derive and display relevant next-event count-down information for in excess of 20 simultaneous channels. CASE STUDY What is IDS? The Network Director’s playout screen showing live streams from two continuity booths and a Continuity IDS is an extendable, network-based Announcer’s screen with visual link to Playout. control and display system designed specifically for the broadcast industry. The solution Consisting of dedicated software and Providing the visual link between the network directors in playout and the isolated hardware devices that use a standard TCP/IP backbone, IDS can be scaled continuity announcers was a straightforward exercise using our configuration software, to suit any installation, delivering IDS Core. -
Configure Surround Sound on an Intel NUC Or Comptue Stick
Surround Sound Setup Guide for NUC This guide will show the recommend method to setup surround sound through bitstreaming. Bitstreaming is the process whereby the NUC sends an un-encoded digital signal to an A/V receiver, to which the receiver will decode the signal, not the NUC, and often produces better quality sound, depending on the receiver. What is Needed: AV Receiver with HDMI or TOSLINK (SPDIF), if using optical audio Surround speakers (5.1 or 7.1) 2 HDMI cables or a TOSLINK cable (a mini DisplayPort to HDMI cable can also be used from the NUC to the Receiver) HDMI display, keyboard, mouse NUC running Windows* Media Player Classic* (https://mpc-hc.org/) 1. Download and install the latest Intel® graphics drivers (https://downloadcenter.intel.com/) 2. Connect the HDMI or mini DisplayPort cable from the NUC to an HDMI input of the AV receiver. If using TOSLINK on the NUC, connect the NUC’s TOSLINK output to a TOSLINK input on the receiver. 3. Start Windows* and download and install Media Player Classic* (MPC-HC) (http://mpc-hc.org/downloads/) 4. Open MPC-HC. On the Menu bar, click View, then Options. 5. On the left side menu tree, click on Internal Filters, then click on Video Decoder (on the bottom of the screen). 6. It’s suggested that Hardware Acceleration be used, especially if 4K content is played, choose a Hardware Acceleration option, then click OK. 7. If 4K or HEVC (h.265) content is going to be played, also select, HEVC, and UHD (4K). -

Can the BBC Survive the Digital Age?
Can the BBC survive the digital age? Laura Payne Neo: A Journal of Student Research March 2010 Abstract The BBC is a public service broadcaster that is highly regarded by the British television audience. However, it is subject to increasing threats to its continuing viability from digital private sector television providers. A part of the threat to the BBC is the way in which it is funded through the TV licence. This article examines the threats to the survival of the BBC through a review of relevant literature and with reference to a survey conducted by the author. The research confirms the high regard in which the BBC is held by the British public and argues for its continuing existence. 2 The BBC has been an extremely successful broadcasting company. However in the approach to the Digital Switchover it faces increasing uncertainty because of competition with new digital commercial channels which hold niche audiences. The future of broadcast television such as the BBC is uncertain, and there are many reasons why it may not survive; ‘the predictions of the death of broadcast television are every bit as loud now as were those of the end of cinema in the face of competition from television’ (Ellis, 2002, p.175). The BBC sees its purpose to support British interests in the world and has a reputation for its impartiality. The BBC is committed to the concept of public broadcasting, providing a platform for local and national debate. It has three main aims; to inform, educate and entertain. In 2001 and 2002 the BBC started operating four free to air digital television channels: ‘BBC 3, a mixed genre, entertainment-led youth channel; BBC 4, a channel for culture, science, the arts and ideas; and two children’s channels’ (Brown, 2004, p.486).
