This year’s NAB show was interesting not so much for what was there as for what was not there. In years past, compression was the technology of the day. Every company had a new type of codec or a new software tool to control the process.
At this year’s show, nary a mention was made of compression. It’s not that such products weren’t there — they were there in a big way — but the technology was hardly mentioned. This just follows the general rule that, when a technology has reached general acceptance and approval, you no longer celebrate the technology, but rather the tools that it spawns. Everywhere on the floor were companies, big and small, showing off tools of the trade using compression. From JVC’s wonderful small HD cameras to Scopus’ H.264 encoders, compression was everywhere.
MPEG is clearly the standard of choice for digital video. Whatever the MPEG incarnation, the digital video world is MPEG. Now, with the ratification of the MPEG-4 standard, a new, scalable coding technique has hit the market. MPEG-4 AVC represents a major improvement in compression technology from MPEG-2 and has been approved for adoption as a mandatory codec for the new HD DVD specification. MPEG-4 AVC and MPEG-4 AAF HE (another standard based on the same compression techniques) were evident in products all over the NAB floor.
KDDI R&D Laboratories
KDDI introduced several interesting H.264/MPEG-4 AVC products for the professional and prosumer markets.
MP-Factory is a software development kit for MPEG-1, -2, -4 and MPEG-4 AVC featuring real-time encoding/decoding/transcoding, frame-accurate editing, audio/video bit-rate conversion and content-based audio/video indexing. The functional APIs are available on multiple operating systems.
MPEG Edit Studio Pro is a nonlinear MPEG-4, HDTV MPEG-2, and high-definition video (HDV) editing tool. The LE version of this program is bundled with JVC’s consumer high-definition camcorder, the GR-HD1, and with its professional high-definition camcorder, the JY-HD10. The program provides nearly lossless, frame-accurate, MPEG-4/MPEG-2/HDV editing. It features logo insertion, scene indexing, a variety of media-conversion capabilities and a software-based HDTV player with a jog/shuttle controller.
Another interesting product from KDDI is the Highlight Creator, an automatic summarization software. Based on content-analysis technology, it summarizes input video in two forms, Skimming and Highlights, and converts summarized video into various formats for streaming and mobile use. Skimming is an outline version of the original content with preferred duration, while Highlights is a series of exciting events. Highlight Creator supports MPEG-7-based metadata description.
Interestingly, KDDI also had a JPEG2000 Hardware HDTV codec, the DHS-2000, which enables low-delay, high-quality transmission (50- to 100Mb/s) of HDTV programs.
Envivio introduced the 4Forum Lite, an MPEG-4 webcasting system. This small, portable appliance enables a networked conference room to broadcast live and on-demand MPEG-4 presentations with synchronized video and the presenter’s PC screen over IP networks. 4Forum Lite uses MPEG-4 to deliver interactive and synchronized webcasts with a subsecond latency and the ability to scale delivery to thousands of viewers. Just plug the VGA cable into your laptop and you can be broadcasting in seconds.
Another Envivio product, 4Front MPEG-4 IPTV, is middleware for network operators. The 4Front middleware creates a client-user interface and fills it with metadata and business rules defined by the network operator. 4Front allows a network operator to offer a complete set of digital TV services.
DG2L Technologies says that its Neuron can deliver high-definition and standard-definition interactive broadcast and IP streams over DVB-S, DVB-C, DVB-T and IP networks. The Neuron STB also offers advanced digital services, including video on demand (VOD), pay per view (PPV), personal video recording (PVR) and MPEG-4 systems-layer interactive program guides.
SkyStream Networks showed the real-time, broadcast-quality MPEG-4 AVC encoding capability of its Mediaplex-20 video delivery platform. The delivery platform provides reliable IP video delivery with forward error correction (FEC), transrating and video-stream replication to different platforms simultaneously, along with bandwidth-rate reduction and MPEG-2 and MPEG-4 encoding and transcoding, all in the same high-density, multichannel chassis.
Now, even Ahead Software has jumped into the compression fray with an update to Nero Digital. The company’s AAC developers have created optimizations to Nero Digital’s HE AAC core codec that include a downsampled HE AAC mode to provide higher-quality playback for AAC devices.
Apple showed off an updated QuickTime that incorporates an HD AVC video codec. The newest QuickTime AVC codec is scalable, allowing content creators to write their content for 3G phones, HD and everything in between. At the show, there were dozens of announcements and demonstrations of AVC, everywhere except in the Microsoft booth. Microsoft has its own proprietary format for this medium.
Microsoft was wooing media moguls with Windows Media 9 HD, mainly announcing integration partners for WM9.
Rainbow DBS' satellite service, VOOM, will use Windows Media 9 as one of the compression technologies when it expands its available satellite capacity for HD.
Akimbo Systems will launch an Internet video-on-demand service for television using Windows Media Video 9 and Windows Media DRM.
U.S. Digital Television will deliver 12 channels in SD using the technology.
Vistacast and WBT Systems will encode curricula in the compression format for datacasting to distance-learning students.
Harmonic demonstrated the DiviCom MV 100 encoding platform running the Windows Media Video 9 Advanced Profile (4:2:0, eight-bit), producing standard-definition digital video for IPTV applications.
Pathfire announced that it is adopting the technology for use in its new Point-to-Point newsgathering system.
Stradis announced that it is adopting Windows Media 9 and will support it on all its future video decoding and encoding products.
TANDBERG Television demonstrated the EN5920 real-time hardware encoder, a dedicated hardware encoding platform for Windows Media 9 Advanced Profile that is currently shipping.
Digital Rapids demonstrated a real-time, software-based, WM9 HD encoder with its multiformat HD capture card, which features extensive A/V preprocessing and the Stream Pro encoding application.
Inlet Technologies demonstrated HD Workbench, an application that streamlines professional encoding from AVI, MPEG-2 and other formats into high-quality, WM9 HD content. Other features include batch-mode encoding, StreamRepair for reliable two-pass encoding, and controls for frame-accurate encoding from a file or tape.
Again, as in the past, compression is playing a large part in the digital revolution. But, this year, it is hidden behind a cloak of great products.
