This paper describes the development of a real-time three-dimensional television (3DTV) emission multiplexer and reception – signal status analyzing system for Advanced Television Systems Committee 8-vestigial side-band (ATSC 8-VSB) & mobile digital television (MDTV) hybrid 3DTV service. Recently, this system has been adopted as a standard (ATSC A/104 Part 5) of the terrestrial 3DTV broadcasting service under the name of service compatible-main and mobile hybrid (SC-MMH) 3DTV. Compared to the existing ATSC MDTV 2D systems, the SC-MMH 3DTV system requires 8-VSB (left-eye images) and MDTV (right-eye images) frame synchronization. 3DTV shall receive both 8-VSB and MDTV signals simultaneously. For a seamless SC-MMH 3DTV service within these service constraints, broadcasters should deploy transmitters and measuring services over the coverage area. In this paper, we introduce the implementation of SC-MMH 3DTV emission multiplexer and reception-signal status analyzer to configure the transmitter and signal measurements more efficiently. The options of the proposed system are verified by the SC-MMH 3DTV field test in a real terrestrial broadcasting environment. [ABSTRACT FROM AUTHOR]

Abstract: In this paper, we propose a novel propagation model for the uncertainty in the reference pixels and the model-based improved intra-refreshment method for the H.264 streaming service through the error-prone channel. The proposed intra-refreshment algorithm can incorporate with the SAD-based low-complexity mode decision as well as the RD-optimizing high-complexity mode decision. Simulations on RTP/IP transmission over mobile channels with the 42.7 and 85.3kbps encoding of QCIF 30 frames/s sequences show that the proposed intra-refreshment scheme improves the average quality of decoded pictures by 1.36–0.47dB compared with the conventional periodic GOB refreshment algorithms.

In this paper, we demonstrate the structure and characteristics of the bandwidth-efficient stereoscopic 3-D broadcasting system entitled service compatible 3-D-TV using main and mobile hybrid delivery (SC-MMH), which enables the broadcasters to provide three different types of services (2-D fixed, mobile, and 3-D) by transmitting only the two legacy broadcast streams (2-D fixed and mobile). By combining the two existing broadcast networks, the proposed system provides high quality 3-D services, fully guarantees backward-compatibility with the legacy fixed/mobile 2-D receivers, and maximizes the channel efficiency. One major feature of the proposed system is bit-rate saving based on the video resolution asymmetry between the left and right eye views, also referred to as “mixed-resolution.” Although it is well-known wisdom that the mixed-resolution stereoscopic videos are perceived close to the higher resolution based on the binocular rivalry suppression theory, the perceived quality also depends on the factors such as scale ratio, viewing distance, bit-rate distribution, and types of codecs. Therefore, we conducted the objective and subjective tests to measure the service quality of the proposed system and find the optimum bit-rate distribution points, and with the results, we demonstrate that SC-MMH can provide the satisfactory quality when the proper level of bit-rate is allocated to the mobile service.
