Computers at the Heart of Consumer Entertainment

Home entertainment has gone a long way from the early 50s when television and stereophonic sounds started to make their presence felt at home. It was a slow and highly iterative evolution, plagued with commercial wars of formats along the way.

You had the video format wars of the late 80s between Sony’s Betamax and Matsushita’s VHS where the latter eventually won. You have the war of high resolution music formats between Sony’s SACD and the DVD consortium’s DVD-Audio where no winner has emerged and both formats appear destined to remain a niche product for high end audiophile folks. Then the latest video format wars came in meant to replace the DVD. You have the same protagonists with Sony and its Blue-ray format on side and Toshiba’s HD-DVD on the other side. 2008 say the resolution of the two formats with Toshiba conceding the battle to Sony. So now you have Blu-ray wining the video format wards but with pathetic market penetration 3 years after it launch.

Meanwhile, there are emerging new developments in the video front that just might derail Blu-ray from ever gaining critical mass from its video markets. This time, it’s about 3D home video aimed at reproducing at home the IMAX 3D experience.

Computers making it all possible

The world of digital technology came to the fore with the increasing power of computers to make Nyquist’s theories become reality in converting real world sound and music into digital bits and stored in laser-readable discs. Within 3 years of its application, the CD has penetrated home markets to replace by attrition our beloved analog systems epitomized by the LP records.

The same technology has been applied to bring movies of the highest level of resolution to our homes, starting with DVD and now Blu-ray. Digital technology made it possible to have multichannel systems and high definition video and audio files that require millions of computing instructions to be processed per second to decode them and render them listenable and watchable on our speakers systems and LCD or Plasma TVs.

- Blu-Ray Players

With millions of bytes representing each frame of images in a 24 frame cycle per second of high definition moving picture, only the most powerful computer processing chips harnessed in these players can render the movies in them pleasantly watchable.

- Plasma and LCD TVs

Those fixed panel displays we have are veritable computer systems that have millions of virtual CPUs controlling each pixel on the display. Differentiated only by display principles, Plasma and LCDs have basically revolutionized the way people watch movies and TV shows at home. High Definition movie materials with 30GB to 60GB of content get decoded by computers in Blu Ray Players and sent as bitstreams over HDMI cables so they get displayed on millions of pixels on processor-based LCD panels or gas bubbles on Plasma TVs.

- Multichannel Sound Systems

Stereo is now a mere 20th century artifact taken over by the multichannel sound craze that started with DolbyPro capable Laser Discs and moved on to DVD discrete 6-8 channel sound. With Blu-ray high definition video, you also get Dolby TrueHD and DTS Master Audio for the ultimate in high definition digital sound requiring powerful decoding chips on receivers to make them engagingly listenable at home.
