根據Futuresource和InterDigital的研究,電視和視頻串流行業的碳排放佔全球總排放的4%,是航空業的兩倍(航空業為2%)。如果在奧運會等重大活動中應用像像素值減少(PVR)技術,將有潛力實現巨大的能源節省。

德拉瓦州威爾明頓,2025年1月22日(GLOBE NEWSWIRE)——對娛樂和視頻通訊服務需求的整體增長突顯了行業對更可持續解決方案的需求。根據移動和視頻技術研究與開發公司InterDigital, Inc.(納斯達克:IDCC)今天發布的一篇報告,由領先的市場研究公司Futuresource撰寫,視頻行業正迅速成為主要的溫室氣體排放者。像素值減少(PVR)等解決方案可以在重大電視事件(如奧運會)期間實現顯著的能源節省。

這份報告《可持續性聚焦:朝向更綠色的電視和視頻價值鏈》分析了視頻娛樂行業從生產到交付和消費所產生的碳足跡。該報告還考察了減少視頻價值鏈環境影響的新興解決方案。

行業面臨的最大挑戰之一來自於範圍3排放,這些排放來自間接來源,如旅行、住宿、餐飲和後期製作。然而,各個領域正在取得進展:

例如,基於IP的遠程虛擬製作可以將行業的碳足跡降低至現場方法的六分之一。
電視仍然是最耗能的設備,但對人工智能和亮度調整技術的投資意味著到2028年,電視的能源消耗將下降15%。
視頻娛樂設備的整體能耗(包括電視、機頂盒、媒體串流器、遊戲主機、智能手機和平板電腦)自2020年以來已下降17%,並預計到2028年將再減少12%,因為舊設備將被更高效的替代品取代。
InterDigital在開發尖端視頻壓縮標準和PVR技術方面領先行業,旨在在不犧牲視頻內容和體驗質量的情況下實現更低的設備能耗。如果PVR技術應用於最近的巴黎奧運會,則大約可節省4800萬千瓦時的能源,相當於為4000個美國家庭提供一年的能源。

“雖然每個人都知道航空業對溫室氣體排放的貢獻——每年佔全球總排放的2%——但電視和視頻串流行業的影響卻不為人知。事實上,這一行業的排放量是航空業的兩倍。”

“整個行業都有責任做出改變,以改善電視和視頻行業的可持續性,”InterDigital視頻實驗室負責人Lionel Oisel表示。“雖然正在進行改變,但還有更多的事情可以和應該去做。像PVR這樣的技術有潛力實現顯著的能源節省,即使在奧運會等特殊活動中應用。如果這一技術能普遍應用,將會帶來巨大的好處,並可能成為行業的遊戲規則改變者。”

成本節省和滿足變化中的觀眾需求的下一代技術需求將推動電視和視頻公司的可持續發展策略。研究強調了行業對環境的幾個影響:

視頻在所有互聯網流量中的比例持續上升,行業估計視頻佔總流量的80%,影響數據中心的二氧化碳排放。
自2023年以來,每小時的電影製作平均產生16.6噸二氧化碳當量(tCO2e),相當於兩個家庭的年能耗。
2024年,電視產生的排放量預計為5400萬噸二氧化碳當量,這大約相當於1170萬輛乘用車的年排放量。
Futuresource報告指出,目前家中安裝的4K電視達到8.58億台,但4K電視每小時產生的排放量約為1080高清電視的1.7倍。
重大體育賽事對環境的影響顯著:今年的巴黎奧運會估計的媒體碳足跡為6.028億噸,因串流電視、手機和筆記本電腦而消耗的電力約為1.25太瓦時(TWh)。

這份完整報告《可持續性聚焦:朝向更綠色的電視和視頻價值鏈》提供了更深入的見解。

編輯評論:

這篇報告突顯了視頻娛樂行業在全球碳排放中的重要性,尤其是在當前氣候變化的背景下,行業的可持續性已成為一個亟待解決的問題。PVR技術的潛力不僅在於節省能源,更在於推動整個行業向綠色轉型。隨著觀眾對環保的關注日益增加,企業若能在可持續性上有所作為,將不僅能提升品牌形象,還能在競爭中佔得先機。

此外,報告中提到的範圍3排放問題,讓我們看到行業內部的複雜性,這不僅僅是技術的問題,更涉及到整個供應鏈的協作。未來,行業需要更多的創新思維和合作,才能有效減少碳足跡,實現真正的可持續發展。

Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a cinematic studio portrait of a woman seated on a simple wooden chair with a minimalist design, positioned slightly to the left of the frame. She is captured in a contemplative pose, with her body turned to the left, her left arm resting gracefully on the back of the chair, and her right hand gently touching her face near her lips, conveying a sense of introspection and elegance. Her long, wavy hair cascades naturally over her shoulders, framing her face and adding softness to the composition. She wears an oversized, textured knit sweater that slips off her shoulders, exposing her collarbones and upper chest, emphasizing a relaxed and intimate mood. Her legs are bare, with her right foot flat on the ground and her left knee slightly raised, creating a dynamic line that guides the viewer’s eye through the composition. *** The background is a seamless, deep charcoal or dark brown studio backdrop, providing a rich, neutral setting that enhances the dramatic lighting. The lighting setup features a single, soft yet directional light source positioned to the left of the subject, casting gentle, sculptural shadows that highlight the contours of her face, shoulders, and arms, while creating a subtle gradient across her form. The light accentuates the texture of her sweater and the natural shine of her hair, adding depth and dimension to the image. The color palette is monochromatic with warm, muted tones—shades of gray, brown, and beige—contributing to a timeless, artistic aesthetic. The image is shot with a professional full-frame camera using an 85mm or 50mm lens at a wide aperture (f/1.8 to f/2.😎 to achieve a shallow depth of field, ensuring the subject is in sharp focus while the background remains softly blurred. The resolution is ultra-high, capturing every detail from the fine texture of her sweater to the subtle expression of her pose. The overall style is elegant, contemplative, and refined, emphasizing mood and atmosphere over overt glamour. Post-processing is minimal, maintaining natural skin tones, enhancing contrast and clarity, and preserving the authenticity of the scene. This portrait embodies a delicate balance between simplicity and emotional depth, making it suitable for fine art, editorial, or fashion photography. Highly detailed, artistic illustration of two cats sitting together on the bustling Nathan Road in Hong Kong. One cat is a sleek black feline with emerald green eyes, the other is a fluffy ginger tabby with white paws. They are perched near the neon-lit storefronts and glowing billboards, surrounded by vibrant city life: crowds of people, bright taxis, and street vendors selling local food. The scene is alive with colorful reflections on rain-slicked pavement, atmospheric mist, and dramatic lighting from neon signs in Chinese characters. The artistry should blend urban realism with a touch of whimsical charm, focusing on the cats' expressive faces and the dynamic ambiance of Nathan Road at night. A hyper-realistic portrait of a man wearing bright yellow neon glasses, his face illuminated with glowing mathematical formulas and physics equations. Warm golden light reflects from his glasses onto his skin. The man has a serious, intelligent expression, short styled hair, and a trimmed beard. His yellow puffer jacket also glows with floating equations and symbols, giving a futuristic holographic effect. Dark teal bokeh lights in the background create depth and contrast.
