    Podcast #1208: HDMI 2.2 Jul 04, 2025
    Show notes

    On this week's show we take a first look at the proposed HDMI 2.2 specification. We also read your emails and take a look at the week's news.

    News:

    • YouTube Once Again Dominates TV Usage In May

    • SunBrite Debuts Full Sun 4K Smart TV Series

    • XGIMI Releases MoGo 4 Series Projectors

    • Amazon to Shutter Freevee in September 2025, Merging Content into Prime Video

    HDMI 2.2 Specification

    The HDMI 2.2 specification, announced by the HDMI Forum at CES 2025, introduces several advanced features to support higher resolutions, refresh rates, and enhanced audio-visual performance. Below is a summary of the key features included in the HDMI 2.2 specification based on the information we have today:

    Increased Bandwidth (Up to 96 Gbps):

    HDMI 2.2 doubles the bandwidth of HDMI 2.1 (from 48 Gbps to 96 Gbps), enabling support for higher resolution and refresh rate combinations, as well as data-intensive applications. This increased bandwidth supports uncompressed and compressed video formats, making it suitable for advanced applications like AR/VR, spatial reality, light field displays, medical imaging, and machine vision.

    Support for Higher Resolutions and Refresh Rates:

    Uncompressed Formats

    1. 4K at 240 Hz and 480 Hz (4:4:4 chroma sampling, 10-bit and 12-bit color).

    2. 8K at 60 Hz and 240 Hz (4:4:4 chroma sampling, 8-bit and 10-bit color).

    3. 10K at 120 Hz.

    4. 12K at 120 Hz.

    5. 16K at 60 Hz.

    Compressed Formats (using Display Stream Compression or similar):

    Supports higher refresh rates like 4K at 480 Hz, 8K at 240 Hz, and 10K at 120 Hz, which require compression to achieve these rates within the bandwidth constraints.

    Next-Generation Fixed Rate Link (FRL) Technology:

    HDMI 2.2 introduces an advanced version of Fixed Rate Link signaling technology, optimized for better support of uncompressed content at high resolutions and refresh rates, ensuring pristine image quality and low latency

    Ultra96 HDMI Cable:

    A new cable type, the Ultra96 HDMI Cable, is introduced to support the full 96 Gbps bandwidth and all HDMI 2.2 features. These cables are backward compatible with older HDMI devices but are required to fully utilize HDMI 2.2's capabilities.

    The Ultra96 cables are part of the HDMI Cable Certification Program, requiring testing and certification with a visible Ultra96 certification label to ensure compliance. Features low electromagnetic interference (EMI) for stable and reliable data transmission.

    Latency Indication Protocol (LIP):

    A new feature designed to improve audio and video "'video synchronization, particularly in multi-hop setups involving devices like AV receivers or soundbars. LIP enhances synchronization over existing methods, reducing issues like lip-sync lag, especially for fast-paced content or gaming.

    Support for Advanced Color and Chroma Formats:

    Supports high-quality color spaces like BT.2020 with 10-bit, 12-bit, and 16-bit color depth. Enables uncompressed full chroma formats (e.g., 4:4:4) at high resolutions, ensuring richer colors and pristine image quality.

    Additional Notes

    • Availability: The HDMI 2.2 specification was announced at CES 2025, with Ultra96 cables expected to be available in Q3/Q4 2025. HDMI 2.2-compliant devices (e.g., TVs, monitors, GPUs) are expected to appear in late 2025 or 2026

    • Optional Features: Like previous HDMI versions, features such as Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Quick Frame Transport (QFT), and Enhanced Audio Return Channel (eARC) remain optional and depend on device manufacturer implementation.

    • Consumer Guidance: The Ultra96 feature name helps consumers identify cables and devices capable of supporting 64 Gbps, 80 Gbps, or 96 Gbps bandwidth, ensuring optimal performance.

    Most Popular HDTV and Home Theater and Automation Products

    On this week's show we take a look at some of the most popular products in our homes.

    Most Popular Devices

    What is the most popular TV size in the USA

    The most popular TV size in the USA is currently around 65 inches, with recent trends showing it overtaking the previously dominant 55-inch size. Data from 2021 indicates the average LCD TV screen size in North America reached approximately 55.5 inches, with expectations of further increases as larger TVs become more affordable and accessible.

    The Definitive Streaming Service Ranking

    We received an email from a listener named Scott that pointed us to an article titled "The Definitive Streaming Service Ranking" written by Josh Rosenberg and published in Esquire magazine. In the article he ranks the top seven streaming services. We'll go through his picks from seven to one. And then we'll give our rankings.

    7 Amazon Prime Video - The main criterion for ranking streaming services is whether they offer at least one new, worthwhile show each month. Prime Video falls short, as it doesn't consistently deliver high-quality new TV content. Instead, it focuses on being a hub for accessing other subscriptions, with shows like Reacher, Fallout, and The Boys feeling like bonuses for Amazon Prime's free shipping rather than a compelling reason to subscribe for streaming alone.

    6 Peacock - Peacock is a top choice for reality-TV fans, offering Bravo's full lineup, including Real Housewives, Love Island USA, Below Deck, Top Chef, and Watch What Happens Live. It also hosts NBC's library with classics like The Office, Parks & Recreation, New Girl, Scrubs, and Law & Order, plus Yellowstone due to an exclusive deal. Its appeal lies in its sitcom and reality-TV vault, and it's the streaming home for the Olympics, though that's only every two years. Fans might find it worth a high price, though it's currently much less than $100 a month.

    5 Disney/Hulu/ESPN+ - The Disney/Hulu/ESPN+ bundle is perceived as a single streaming service due to its long-standing integration, with Disney enhancing this by adding Hulu and ESPN+ tiles to the Disney+ home screen for seamless access. Each service offers unique strengths: Disney+ excels in Marvel, Star Wars, and children's content; Hulu features FX shows like The Bear and Shōgun, plus ABC's lineup, including Abbott Elementary; and ESPN+ remains a leader in live sports despite growing competition. Their combined appeal keeps them competitive, as they are stronger together than individually.

    4 Netflix - Netflix benefits from long-term subscriber relationships, with users browsing its platform like they once did with cable TV. However, its content quality is declining, with more misses than hits. The upcoming conclusion of major shows like Squid Game and Stranger Things in 2025 could further challenge its ability to retain subscribers.

    3 Paramount+ - Paramount+ benefits from Taylor Sheridan's popular shows like Yellowstone, Landman, and 1923, and its merger with Showtime has brought quality series such as MobLand and Yellowjackets. However, the streaming service struggles to justify its subscription cost as essential, with its success hinging on the delivery of Sheridan's planned spin-off universe.

    2 Apple TV+ - Apple TV+ has significantly improved its content in 2025, with successful shows like Severance season 2, The Studio (Seth Rogen), Your Friends and Neighbors (Jon Hamm), and Stick (Owen Wilson). Previously, subscribing only for specific shows was advisable, but now, due to consistent high-quality releases with A-list talent, keeping the subscription active is recommended. If this trend continues, Apple TV+ will remain a strong competitor in the streaming market.

    1 HBO Max - HBO tops the power ranking due to its consistent delivery of high-quality TV shows that justify the subscription cost. With a business model focused on quality since its launch over 50 years ago, HBO has aired acclaimed series like The Pitt, The White Lotus, The Last of Us, The Rehearsal, and Hacks in the first half of 2025. Its extensive library includes some of the greatest shows and movies, such as Goodfellas. While Netflix prioritizes quantity, HBO Max excels in quality.


    Podcast #1205: Betamax Turns Fifty Jun 13, 2025
    Show notes

    Can you believe Betamax turns 50 this month? On this week's show we look at how the VCR changed the entertainment industry and gave us a reason to build our home theaters. We also read emails and take a look at the week's news.

    News:

    • YouTube Is Swallowing TV Whole, and It's Coming for the Sitcom
    • Roku adds more premium features to its own line of midrange TVs

    Other:

    The Betamax Turns 50 this Month

    In the late 1970s, the arrival of the Video Cassette Recorder (VCR) sparked a seismic shift in entertainment, as detailed in a recent Hollywood Reporter feature. Initially met with skepticism by studios fearing piracy, the VCR became a cultural juggernaut, reshaping how audiences consumed media and how Hollywood operated. By 1987, home video revenue surpassed theatrical box office earnings, with VHS tapes turning movies like Top Gun into cultural touchstones that families could own and rewatch endlessly.

    The VCR democratized access to films, birthing the video rental industry—think Blockbuster's neon-lit aisles—and empowering consumers to curate their viewing experiences. It also gave studios a lucrative new revenue stream, with tapes priced high for rentals before dropping for mass ownership. Yet, the technology wasn't without flaws: tracking issues, bulky machines, and the dread of "Be Kind, Rewind" defined the era.

    Beyond movies, the VCR enabled niche content to thrive, from fitness tapes to obscure genres, while fueling Hollywood's sequel-driven franchises. As The Hollywood Reporter notes, the VCR's legacy endures in today's streaming wars, where on-demand viewing owes its roots to those clunky cassettes. The VCR didn't just change Hollywood—it rewired how we connect with stories.

    Here are some fun facts about the VCR (Video Cassette Recorder):

    • First Commercial VCR: The Ampex VRX-1000, introduced in 1956, was the first commercially available VCR. It cost around $50,000 (equivalent to over $500,000 today) and was primarily used by TV studios, not homes.
    • Home VCRs Arrived Late: The first consumer VCR, the Philips N1500, hit the market in 1972 in the UK. It was pricey (around £400, or $4,000 today) and could only record for about an hour.
    • Format Wars: The 1970s saw a fierce battle between Sony's Betamax (1975) and JVC's VHS (1976). VHS won due to longer recording times (up to 4 hours vs. Betamax's 1 hour initially) and better marketing, despite Betamax's slightly superior picture quality.
    • Rental Boom: Video rental stores exploded in the 1980s because VCRs were affordable, but tapes were expensive ($50-$100 each). The first Blockbuster opened in 1985, capitalizing on this trend.
    • Time-Shifting Revolution: VCRs introduced "time-shifting," letting people record TV shows to watch later. This was groundbreaking, though networks initially feared it would kill live TV. A 1984 U.S. Supreme Court ruling upheld home recording as legal, boosting VCR popularity.
    • Early Adopters' Struggles: Early VCRs were clunky, with complex controls. The infamous "blinking 12:00" on VCR clocks became a cultural joke because many users couldn't figure out how to set the time.
    • Global Impact: By 1980, only about 1% of U.S. households had a VCR, but by 1990, over 70% did. Japan led early adoption, with companies like Sony and JVC driving innovation.
    • Peak Sales Period (1977–2000): The VCR was a dominant consumer electronics product for about two decades. We can estimate U.S. sales alone at approximately 100–200 million units over this period.
    • Market Decline: VCR sales peaked in the 1980s and 1990s but declined sharply in the early 2000s as DVDs overtook VHS. By 2003, DVD sales surpassed VCR sales, and the last VCRs were manufactured by Funai in 2016.

    Podcast #1204: Can Future OLED Screens Become Multi Channel Speakers Jun 06, 2025
    Show notes

    On this week's show our listeners have provided the topics. We discuss a $30 hack to improve your TV as well as a new OLED technology that may turn your screen into a multi channel speaker. Plus we read your emails and take a look at the week's news.

    News:

    • 'Stranger Things' Season 5 Gets Three-Part Release, Series Finale Set for New Year's Eve
    • 66% see YouTube as destination for long-form movies, TV shows
    • Scorsese Doesn't Go To Cinemas Anymore
    $30 Dollar Hack to Improve Your TV

    One of our listeners, Scott, sent us a link to an article suggesting that a $30 LED strip can significantly enhance your TV viewing experience. The full article is titled I stuck this $30 LED strip on the back of my TV. My eyes thank me daily. We'll summarize here but check out the article for more detail.

    The author of the PCWorld article shares his positive experience with a $30 USB-powered LED strip, initially inspired by the concept of bias lighting to reduce eye strain by counterbalancing a TV's bright display. After research, the budget-friendly strip proved easy to install, powered directly by the TV, and automatically synced with the device's on/off function.

    Installation was simple, involving a clean surface and careful placement of the adhesive-backed strip along the TV's rear edges, cut to fit for even light distribution. The soft, ambient glow reduced eye fatigue, enhanced contrast and color vibrancy, and made dark scenes in movies and games more enjoyable, proving a cost-effective alternative to pricier lighting systems, and a recommended upgrade for better comfort and visual quality.

    Turn Your OLED Screen Into a Multi Channel Speaker

    And another listener, Bob, sent us an article about a technology being developed that could lead to the world's first Pixel-Based Local Sound OLED (PLS-OLED) display. It would allow each pixel to emit different sounds simultaneously, effectively turning the display into a multichannel speaker array. This breakthrough was successfully demonstrated on a 13-inch OLED panel, similar to those used in laptops and tablets. The technology could potentially revolutionize applications in devices like smartphones, tablets, laptops and possibly televisions by combining visual and audio functions in a single, ultra-thin panel. The study was published in Advanced Science in 2025.

    This is our take on how this technology can be used to enhance a home theater system for some users:

    • Integrated Audio-Visual Experience:
      • Fewer Speakers: With PLS-OLED, the audio comes directly from the screen, eliminating the need for external speakers and creating a cleaner, more streamlined setup.
      • Immersive Sound: Since each pixel can emit distinct sounds, the technology enables precise, localized audio output. This means sound can appear to come directly from the action on screen. A character's voice would originate from their mouth or an explosion sounding like it's bursting from the exact spot on the display—enhancing the realism of the home theater experience.
    • Multichannel Audio Without Additional Hardware:
      • Surround Sound Simulation: The multichannel capability of PLS-OLED can mimic surround sound to some degree by directing different audio channels through various parts of the screen. However, we don't see this replacing a good 7.1 setup, rather it would enhance the audio.
    • Enhanced Aesthetics and Space Efficiency:
      • Reduced Equipment: By integrating high-quality audio into the display, you eliminate the need for a separate audio receiver, subwoofers, and multiple speakers, saving space and reducing setup complexity.
    • Potential for Advanced Applications:
      • Personalized Audio Zones: In a home theater shared by multiple viewers, the pixel-based sound could theoretically create localized audio zones, allowing different people to hear optimized sound based on their seating position, though this might require further development or additional hardware like head-tracking.
      • Possibly delivering a more accurate 3D audio experience directly from the screen.
    • Practical Considerations:
      • Installation Ease: Unlike traditional systems that demand careful speaker placement and calibration, PLS-OLED simplifies setup—just mount the display and connect it to your media source. This is ideal for users who want a plug-and-play home theater solution.

    Limitations and Next Steps:

    • Sound Power: The article doesn't specify the volume or frequency range of the audio output. Most of us want deep bass and loud, clear sound, so in reality you would still want a subwoofer for a fuller sound.

    Conclusion: The Pixel-Based Local Sound OLED technology could revolutionize simple home theaters by combining high-quality visuals and multichannel audio in one device, delivering a more immersive, space-efficient, and aesthetically pleasing experience. It's particularly promising for compact setups or users seeking simplicity without sacrificing sound quality.
