ADVANCED TV

MULTIPLE HD STREAMS PER TV:

The FCC’s 100 squared (100Mbps to 100M households) project is already obsolete. It only supports three MPEG2 streams at 1080P, and with ~3.5 TVs/home, that’s only one stream per TV or DVR. So what about picture-in-picture or picture marquee with multiple sports channels, multiple traffic cameras, multiple surveillance cameras, or multiple video conference participants, all in HD? The move to 3-D TV will double the bandwidth requirement.

MULTIPLE OUTBOUND STREAMS PER HOME:

Cheap & small CMOS image sensors (cameras like in your phone) are going everywhere: front door, back door, kid’s room, garage, back yard, fish tank, etc. Imagine monitoring dozens of outbound HD video streams from anywhere.

ULTRA-HIGHDEF TV:

Japan Broadcasting Company already demonstrated UHDTV on a 30-foot diagonal wall with 32M total pixels (7680x4320 pixels vs. 1920x1080, or 2M for HDTV) at 60 frames/sec (vs. 30/sec for 1080p). The demo supported 22.2 channel audio, required 3.5 TB of storage for the 18 minute video, and consumed 24 Gbps of network capacity. That was FIVE YEARS AGO! Newer demos include holography.

UNCOMPRESSED VIDEO:

Compression reduces bandwidth requirements but adds latency delays, which can impact action sport videos and high-twitch gaming.

FAST CHANNEL SWITCHING:

Moving from the broadcast TV model to an IPTV or on-demand model means not just switching to a different frequency band on cable but to a different video server and service provider. FTTH with low latency would lessen the noticeable delay of that switch.
