We propose a novel inference technique based on a pretrained diffusion model for text-conditional video generation. Our approach, called FIFO-Diffusion, is conceptually capable of generating infinitely long videos without additional training. This is achieved by iteratively performing diagonal denoising, which concurrently processes a series of consecutive frames with increasing noise levels in a queue; our method dequeues a fully denoised frame at the head while enqueuing a new random noise frame at the tail. However, diagonal denoising is a double-edged sword as the frames near the tail can take advantage of cleaner ones by forward reference but such a strategy induces the discrepancy between training and inference. Hence, we introduce latent partitioning to reduce the training-inference gap and lookahead denoising to leverage the benefit of forward referencing. Practically, FIFO-Diffusion consumes a constant amount of memory regardless of the target video length given a baseline model, while well-suited for parallel inference on multiple GPUs. We have demonstrated the promising results and effectiveness of the proposed methods on existing text-to-video generation baselines. Generated video samples and source codes are available at our project page.

The Google Stadia controller used for playing games on Google's video game streaming service. The Stadia controller (priced separately at $69) uses WiFi to connect directly to the game running in Google's video game streaming service .the Google has shed some more clarity on its upcoming cloud-based video game service: an entry price, launch window and some of the games you will be able to play. Google's Stadia will become available in November with an entry price of $129.99 for the Founders Edition package (pre-order on Google's Stadia site), which includes a game controller, Chromecast Ultra streaming device and a three-month subscription. Cloud gaming promises to make it easier for consumers to play online games, as it sidesteps the need for pricey gaming PCs or console video game systems.

Robert Bosch Venture Capital GmbH (RBVC), the venture capital arm of global automotive parts supplier Bosch Group, has completed an investment in mapping startup DeepMap Inc, a start-up based in Palo Alto, California that is building high definition maps specifically for self-driving vehicles. DeepMap is focused on solving the mapping and localization challenge for autonomous vehicles. The investment amount was not disclosed. "Maps explicitly designed to be read by machines are a critical enabling technology for safe autonomy. DeepMap fills a vacuum in the market. The company's approach to mapping, which leverages embedded software on the vehicle, is very compelling and relevant for highly automated as well as autonomous driving, within Bosch and the whole automotive industry," says RBVC Managing Director Dr. Ingo Ramesohl.

The PlayStation 4 Pro has just one problem, but it's a doozy: I can't show you why it exists. Sony's souped-up $399 super-console, due Nov. 10, is all about making things faster, or prettier, or both. But one of its chief attractions, 4K graphics (or let's call them "4K-ish"), needs an "ultra high definition" 4K television to shine -- a format with roughly four times the visual fidelity of today's mere "high def" 1080p displays. The 43-incher I bought with those features to run the PS4 Pro unit Sony sent over set me back in the vicinity of $800. And it's conveying to someone why they'd want to drop that kind of dinero on this console that's the trick.
