The popular concept of television anytime, anywhere and on any device may be Internet driven, but it could not exist without Content Delivery Networks (CDN) — the speedy enablers that work quietly behind the scenes connecting video programs to end users.
While not the most wide-spread DTV standard, ISDB-T still offers many advantages.
Viewers and broacasters all want more channels.
Pay TV companies and Telcos are trying to tackle three big questions (1) How to stay relevant (2) How to respond to OTT Services and (3) How to reduce the OPEX and CAPEX costs of STB’s and other hardware. In this paper we examine the choices for virtual services, software, dongles, STB’s and Home Gateways.
LTE Broadcast is the mobile industry’s latest attempt to develop a viable technology for multicast transmission over cellular backhaul infrastructures and on through the Radio Access Network (RAN), after a litany of previous failures such as DVB-H (Digital Video Broadcasting- Handheld) and in the US Qualcomm’s MediaFlo.
Multichannel has become the norm. Now you need an automated QC solution.
Multichannel distribution of live broadcasts offers local programmers the ability to reach a wider consumer base. The TV Everywhere movement has created a consumer climate in which people want the ability to watch any program at any time. This includes live coverage on mobile devices and laptops, so consumers on the go can continue to access the programming they want. However, QoS monitoring is critical to ensuring that live content in any applicable file format can reach viewers on any device.
Since the dawn of television, studios around the globe have relied on coaxial cables to connect the broadcast world: cameras to recorders to mixers to routers to encoders. But studio coax may be on the brink of extinction. Like their colleagues in headends and uplinks, video engineers are swapping 75-ohm coax for IP cables.
Over the decades from our industry’s move from analog to digital based technology, codecs (encoders and decoders) have played a key role in the capture, editing, and distribution of video media. The MPEG-2 codec has supported all three tasks. Camera oriented codecs have moved from MPEG-2 to MPEG-4 (H.264). Distribution has followed two paths. Television program distribution continues to employ MPEG-2. Internet distribution immediately went to progressive video encoded using H.264 because the codec is about 2X more efficient than MPEG-2. The newest distribution format is H.265 or HEVC (high efficiency video codec).
