A new Digital Terrestrial Television Broadcasting (DTTB) system, called Television (TV) 3.0, is being developed in Brazil and is expected to be on air by 2025 under the commercial name DTV+. It started with a Call for Proposals (CfP) for its systems components, for which organizations worldwide have submitted candidate technologies. After two testing and evaluation phases, the technologies for all layers were selected, the TV 3.0 architecture was completely defined, and the standards were written. It consists of modern Modulation and Code (MODCOD) techniques, mandatory transmission and reception in Multiple-Input Multiple-Output (MIMO) with cross-polarized antennas, an app-oriented interface, an Internet-based Transport Layer (TL), and state-of-the-art efficient coding for audio, video, and captions. This set of technologies will allow for several new use cases that change the user experience with TV, such as Geographically Segmented Broadcasting (GSB), targeted advertising, sensory effects, and interactivity. This paper reviews the phases already concluded for the TV 3.0 project and presents its potentialities and the current developments at its final stage.

Many efforts to achieve cost savings through simulations have been ongoing in the cyber-physical system (CPS) industry and manufacturing field. Recently, the concept of digital twins has emerged as a promising solution for cost reduction in various fields, such as smart cities, factory optimization, architecture, and manufacturing. Digital twins offer enormous potential by continuously monitoring and updating data to study a wide range of issues and improve products and processes. However, the practical implementation of digital twins presents significant challenges. Additionally, while various studies have introduced the concepts and roles of digital twin systems and digital components, further research is needed to explore efficient operation and management strategies. This paper aims to present digital entity management methodology for the efficient implementation of digital twin systems. Our proposed class-level digital entity management methodology constructs complex and repetitively used digital entities into digital entity classes. This approach facilitates the abstraction, inheritance, and upcasting of digital entity classes. By leveraging class-level management and easily reusable and modifiable digital entities, the implementation of low-complexity digital twin systems becomes feasible. The proposed methodology aims to streamline the digital twin implementation process, addressing complex technical integration and practical implementation challenges.

This paper presents an advanced rate control (ARC) algorithm for Versatile Video Coding (VVC). The proposed method is based on spatial coupling strategy and improved Broyden Fletcher Goldfarb Shanno (BFGS) algorithm to achieve a high performance rate control (RC). In this paper, we address the problem that the current coding block does not fully utilise the spatial information during the encoding process. Firstly, a parameter updating strategy at the coding tree unit (CTU) level is constructed based on spatial coupling strategy. The spatial coupling strategy established the relationship between video parameters and video texture, which enables the video parameters at the CTU level to be more closely aligned with the video content. Furthermore, in order to enhance the precision of RC, we have proposed an improved BFGS algorithm to update video parameters, which utilizes the optimal search direction of the different partial differentials and sets an adaptive speed control factor. The experimental results indicate that the proposed method offers better performance compared to the default RC in VVC Test Moder (VTM) 19.0, with Bjøntegaard Delta Rate (BD-Rate) savings of 6.35%, 5.09% and 5.43% under Low Delay P, Low Delay B and Random Access configurations, respectively. Moreover, the proposed method demonstrates superior performance compared to other state-of-the-art algorithms.

The complex distortions suffered by real-world underwater images pose urgent demands on accurate underwater image quality assessment (UIQA) approaches that can predict underwater image quality consistently with human perception. Deep learning techniques have achieved great success in many applications, yet usually requiring a substantial amount of human-labeled data, which is time-consuming and labor-intensive. Developing a deep learning-based UIQA method that does not rely on any human labeled underwater images for model training poses a great challenge. In this work, we propose a novel UIQA method based on domain adaption (DA) from a curriculum learning perspective. The proposed method is called curriculum learning-inspired DA (CLIDA), aiming to learn an robust and generalizable UIQA model by conducting DA between the labeled natural images and unlabeled underwater images progressively, i.e., from easy to hard. The key is how to select easy samples from all underwater images in the target domain so that the difficulty of DA can be well-controlled at each stage. To this end, we propose a simple yet effective easy sample selection (ESS) scheme to form an easy sample set at each stage. Then, DA is performed between the entire natural image set in the source domain (with labels) and the selected easy sample set in the target domain (with pseudo labels) at each stage. As only those reliable easy examples are involved in DA at each stage, the difficulty of DA is well-controlled and the capability of the model is expected to be progressively enhanced. We conduct extensive experiments to verify the superiority of the proposed CLIDA method and also the effectiveness of each key component involved in our CLIDA framework. The source code will be made available at https://github.com/zzeu001/CLIDA.

In learning vision-language representations from Web-scale data, the contrastive language-image pre-training (CLIP) mechanism has demonstrated a remarkable performance in many vision tasks. However, its application to the widely studied video quality assessment (VQA) task is still an open issue. In this paper, we propose an efficient and effective CLIP-based Transformer method for the VQA problem (CLIPVQA). Specifically, we first design an effective video frame perception paradigm with the goal of extracting the rich spatiotemporal quality and content information among video frames. Then, the spatiotemporal quality features are adequately integrated together using a self-attention mechanism to yield video-level quality representation. To utilize the quality language descriptions of videos for supervision, we develop a CLIP-based encoder for language embedding, which is then fully aggregated with the generated content information via a cross-attention module for producing video-language representation. Finally, the video-level quality and video-language representations are fused together for final video quality prediction, where a vectorized regression loss is employed for efficient end-to-end optimization. Comprehensive experiments are conducted on eight in-the-wild video datasets with diverse resolutions to evaluate the performance of CLIPVQA. The experimental results show that the proposed CLIPVQA achieves new state-of-the-art VQA performance and up to 37% better generalizability than existing benchmark VQA methods. A series of ablation studies are also performed to validate the effectiveness of each module in CLIPVQA.

For efficient point cloud broadcasting, point cloud compression technologies serve as the foundation, which plays a crucial role in immersive media communication and streaming. Video-based point cloud compression (V-PCC) is the recently developed standard by the Moving Picture Experts Group (MPEG) for dynamic point clouds. Its original fixed-ratio bit allocation (FR-BA) method in the unique all intra (AI) structure leads to a significant rate-distortion performance gap between the rate control manner and the fixed quantization parameters (FixedQP) scheme, as evidenced by significant increases in BD-Rate (Bjøntegaard Delta Rate) for both geometry and attribute. To address this issue, we propose a distortion propagation model-based frame-level bit allocation method that is specifically tailored for AI structure in V-PCC. First, the analysis is carried out for the distortion propagation model inside the group of pictures (GOP) for the AI configuration. Second, the skip ratio of 4x4 minimum coding units (CUs) is utilized to predict the distortion propagation factor. Third, the occupancy information is employed to refine the distortion propagation model and further enhance compression performance. Finally, experimental results demonstrate the effectiveness of the proposed distortion propagation model-based frame-level bit allocation method. Specifically, experimental results reveal that the proposed method achieves BD-Rate reductions of 0.92% and 4.85% in geometry and attribute, respectively, compared to the FR-BA method. Furthermore, with the introduction of distortion propagation factor prediction incorporating occupancy correction, the BD-Rate reductions are further extended to 2.16% and 6.13% in geometry and attribute, respectively.

The capability of QC-SC-LDPC codes to be employed in broadcasting systems has been studied in previous research. However, the implementation-oriented features such as rate-compatibility and length-scalability for QC-SC-LDPC codes have not been well studied yet. In this paper, we first propose a new implementation-oriented structure of QC-SC-LDPC codes for broadcasting systems, with support for rate-compatibility and length-scalability. Then, the three-dimensional (3D-) grid-based (G-) progressive edge growth and lifting (PEGL) method is proposed to construct QC-SC-LDPC codes with that structure, which can achieve desirable performance across different code rates and code lengths within the given design complexity. Finally, a family of rate-compatible length-scalable QC-SC-LDPC codes are constructed via the 3D-G-PEGL method, and simulation results demonstrate the effectiveness of that method. Furthermore, the scaling behaviors of QC-SC-LDPC codes are observed from the provided simulation results.
