With the end of analog broadcasting in sight, we at VALTES are aggressively conducting groundbreaking research and development in the creation of testing systems for newly launched "multimedia broadcasts. Since local TS capture alone is not sufficient, we are taking advantage of strengths in TS creation to support tests that have grown inefficient.

Questions that emerge are: "How deep should verification go? Advanced Technological Research. As professional software testing specialists, we at VALTES are bringing our sense of mission and love of challenge to advanced technologies that have yet to find market application.

Multimedia broadcasting refers to a host of conjoined, next-generation media services that maximize each particular medium's distinctive traits whether "broadcast" or "telecommunication" services. The following are some of the major services being realized through multimedia broadcasting. Note that internet connections, too, also further expand the possibilities. Classifying the new challenges of the multimedia broadcast framework into "how receivers should look" and "what the shape of content delivery should be," we are creating test cases and test viewpoint lists extracted from each single or combined functionality.

In conjunction with this, we are singling out differences with conventional ISDB-T and conducting research into transmission patterns that will enable us to create TS for either real-time or storage type broadcasting.

We are also pushing ahead with development to enable creation of specialized and customized TS that address different maker specifications and test worthy functions. We create and own specialized TS developed from our own vantage point outside of Dpa, and as a result, have been fielding many orders for receiver assessment.

We retain and operate various TS creation and delivery equipment. We create test cases and TS to confirm time elapsed switching to different visual formats or viewer age restrictions.

In addition to creating ABNT compliant data, we are expanding TS and test cases to respond to future needs such as TS creation for changes that occur in general event scheduling in Japan.

Multimedia Broadcasting under ISDB-Tmm Format in Japan

Since then, many countries have adopted ISDB over other digital broadcasting standards. The concept was named for its similarity to ISDN as both allow multiple channels of data to be transmitted together a process called multiplexing. This broadcast standard is also much like another digital radio system, Eureka , which calls each group of stations on a transmitter an ensemble ; this is very much like the multi-channel digital TV standard DVB-T. The various flavors of ISDB differ mainly in the modulations used, due to the requirements of different frequency bands.

Multimedia Broadcasting, which has adopted the ISDB-Tmm standard for multimedia broadcasting, has been commissioned as the sole carriage operator providing nationwide multimedia broadcasting services for mobile devices scheduled to start following the termination of the analogue broadcasting service in Japan. In Japan, Multimedia Broadcasting, the newly commissioned carriage operator, and other members of the ISDB-T Multimedia Forum have been engaged in a wide range of activities targeted at commercial broadcasting services starting in the spring of The ISDB-Tmm standard employs the concatenated transmission method which, combining some blocks of the segment 5. As a concatenated transmitter for the segment The ISDB-Tmm standard has a high degree of compatibility with the ISDB-T format, making it possible to share the same receivers for different broadcasting services and cut down on transmission costs.
