Transitioning television to Internet-style one-to-one addressable advertising can be done gradually in cable television, while implementing the SCTE 130 standard from the Society of Cable Telecommunications Engineers, by utilizing a virtual zoning approach.
Delivering video across a variety of platforms involving multiple codecs can be efficiently handled by multicore media processors. Part One is an overview of the challenge and the codecs involved (including the rarely-mentioned MPEG-3!)
The cable-TV industry needs to move to targeted advertising, but cost challenges such as HD ad splicing and additional infrastructure requirements make it slow going. Here’s a gradual approach that cable-TV MSOs can begin deploying without the need for new set top boxes.
DisplayPort’s killer feature may be its ability to support multi-display monitors from a single digital output port and provide full display performance with zero latency, while consuming less power and costing less than other multi-monitor solutions.
An overview of the image sensor processing pipeline, including camera front-end IP implementation on a low-cost FPGA fabric, Bayer to RGB conversion and efficient use of memory.
Built In Self Test (BIST) in active HDMI and other high-speed digital cables provides better accuracy and cost savings compared with earlier in-production testing methodologies, and can also improve production line performance.
The market for video surveillance keeps burgeoning. Here’s a review of smart video surveillance technology and the challenges for embedded system designers, and an example of intelligent surveillance design using the Blackfin processor to provide the control and image processing.
Understanding how diversity antenna systems work, and how Mobile Digital TV viewing can be improved through the use of multiple antennae — even for space-constrained portable devices, and for in-vehicle and deep-indoor reception.
Understanding the causes of deterministic and random jitter in SDI and other digital video signals, and how to minimize jitter in the design of pro video equipment meeting SMPTE specs.
Picture quality measurements based solely on detecting the noise differences between the reference and test videos fail to account for the characteristics of human perception and have broad limitations as a result.
How to convert the H.264 Loop Filter problem, which is sequential in nature, into a vector oriented/ parallel process that efficiently uses SIMD architecture.
A new generation of scalable video codecs is being developed to augment the capabilities of H.264.
DisplayPort offers small connector size and low cost, and the bandwidth of a single DisplayPort cable can support a 1080p @120Hz panel, or up to four 19-inch 1440×900 panels, as well as HDCP content protection. And it’s catching on beyond PCs. A look inside the DisplayPort receiver.
HDMI can be a highway for ESD to enter the system chip, but an integrated HDMI interface solution can provide the protection needed, while helping reduce manufacturing costs.
HDBaseT is optimized for video applications and can connect all the entertainment devices in a home by providing the “5Play” convergence of uncompressed full HD digital video, audio, 100BaseT Ethernet, power over cable and various control signals.
Custom codecs can accelerate digital multimedia product development because codecs optimized for the hardware platform for which the multimedia application is developed allow product developers to focus on differentiating the product from competitors.
