Japanese digital terrestrial TV stations have ceased analog TV broadcasting and shifted to digital TV except for in a few areas. Today, new broadcasting/communication services such as multimedia broadcasting and white space utilization are beginning using the bandwidths vacated by analog broadcasting. Existing broadcasting stations are also advancing efforts for responding to diversification of viewing environments. For example, by introducing Internet broadcasting and other measures such as the secondary use of new contents, which are aimed at meeting the networking needs of the times. This strategy is expected to promote a shift from the previous tape medium to filebased media and the construction of new intra-station systems by applying IP protocol to the TV station networks. This paper introduces the orientation of a next-generation service platform capable of supporting the new services that the TV stations are expected to start up in the near future in order to meet the needs of diversifying video content.

The codec used for transmitting video material is, in principle, subject to various operational limitations as a result of its encoding latency, so there was a need for lower latency encoding. In this paper, NEC introduces a newly developed codec device based on the latest H.264/MPEG-4 AVC video encoding standard to achieve minimum 10 ms codec latency while maintaining broadcast quality.

The role of broadcasting stations in news production workflow is primarily to promptly communicate accurate information. The changeover from tape media to file-based media usage, including that used in news coverage of on-air broadcasting can improve the workflow that used to impose a lengthy time longer than actual recording hours. In this paper, the authors also introduce a solution that makes news broadcasting more flexible and faster by the effective utilization of metadata.
