Development of digital multimedia broadcasting

Satellite radio systems are actually part of a larger group of broadcasting mediums, which specialists refer to as Digital Multimedia Broadcasting or DMB. This digital transmission system is used in order to send data to different receivers such as radios, television sets or mobile phones and PDAs. There are two different ways of using digital multimedia broadcasting - S-DMB which is broadcasting via a satellite or T-DMB which uses terrestrial emitters.

The complexity of the entire digital multimedia broadcasting field is huge. Out of all the features and characteristics digital broadcasting offers, satellite radio is probably the most spectacular as it generated immense interest and triggered an intense competition between the two main satellite radio broadcasters, Sirius and XM Radio.

The development of satellite radio and other forms of digital broadcasting is spectacular because it offers two main qualities that terrestrial emitters are deficient in: quality and coverage. In the case of satellite radio, for example, the sound quality from a satellite broadcast is much higher than AM or FM broadcasts, as the hissing noises and transmission disturbances are eliminated.

Technical features of digital multimedia broadcasting - overview
Whether it refers to television, satellite radio or cell phone transmissions, digital multimedia broadcasting is based on the Eureka 147 DAB standard. Digital television uses the T-DMB which is made for transmissions on frequency bands III (VHF) and L (SHF). T-DMB is an ETSI standard (TS 102 427 and TS 102 428).

T-DMB uses MPEG-4 Part 10 (H264) for the video and MPEG-4 Part 3 BSAC or HE-AAC V2 for the audio. When it comes to satellite radio, there were a few issues to be resolved by the main satellite radio broadcasters. The satellite radio receiver needs to be in the line of sight of the satellite to receive the transmission – and there is the problem of having different landscaping objects block the direct transmission. Land based devices were installed in order to eliminate the lack of direct satellite transmission. Since the wider spectrum of broadcasts has to be covered, digital multimedia broadcasting uses OFDM-4DPSK modulation and a chip of T-DMB receiver is also provided by MPEG-2 Transport Stream De-multiplexer. This helps reduce the negative effects of shadowing and fading, present in many digital transmissions.

The future of digital multimedia broadcasting
The transfer from the analog world to the digital one is obvious in all fields of work. Since digital multimedia broadcasting is developing so quickly, there is a silent battle going on between the new age digital technology and the classic analog one. OF course, many compare the transition from the analog to the completely digital era with the way audio cassettes were replaced by CDs and later on even DVDs. However, the development of digital multimedia broadcasting is slower since it happens on so many levels at the same time. Digital television is taking us into new spaces that are basically hybrids of the features of regular TV and characteristics of the Internet.

Satellite radio is also taking huge leaps forward, with more and more programs having satellite radio exclusivity. There are even discussion of moving events like the MLB exclusively on satellite radio, which would provide one of the first deadly strikes against terrestrial radio broadcasting. Digital data transmission is fast and accurate, and so far reality proves that the satellites used in order to facilitate broadcasting and reliable. Most digital multimedia broadcasting companies that own satellites also have backup ones ready to go in orbit and replace a defective one.

Some other benefits of digital multimedia broadcasting recommend it as a next step in the development of broadcasting. From the consumer’s point of view, the quality and interactivity options of digital TV or satellite radio broadcasts are important features. Although most digital multimedia broadcasting channels and technologies are still complex and sometimes expensive, the evolution of digital broadcasting seems to be here to stay.

Interoperable Satellite Radios

The satellite radio world is divided among the two major broadcasters, XM Radio and Sirius. Since they work on different frequencies and need specific equipment to broadcast, Sirius and XM Radio have divided the market into two groups. While some are fans of the Sirius channels others prefer XM Radio, and the debate regarding which of the two is the best could go on forever. Some however are subscribers to both services, since they love some of the Sirius programs but also enjoy XM Radio broadcasting. For them and for more people interested in satellite radio, there are some potential good news. Interoperable satellite radios are one of the things most of the major players in the satellite radio industry are talking about. What are they? Basically they are receivers that can work both with Sirius and XM Radio and everything is enclosed in a single unit.

Interoperable Technologies – when Sirius and XM work together
Interoperable Technologies is the name of a joint effort funded by both Sirius and XM Radio, with the declared purpose of bringing dual-subscription satellite radios to the general market. Founded in 2003, Interoperable Technologies has started developing the dual-mode satellite radios ever since and progress is being made with each passing month. Interoperable Technologies gets help from consultants from both XM and Sirius and their 2005 success of developing a singe unit that can receive both transmissions was a notable one. Today, Interoperable Technologies ha a deadline of bringing the developed receiver unit to the market. The monthly subscription price is estimated to be around $26 – for which you get over 300 channels from the combined broadcasting list of the two satellite radio operators.

What the people say…
The news of the interoperable satellite radio development has triggered interesting responses among XM and Sirius satellite radio subscribers. Here are some of the things people left on forums and discussion boards regarding this development:

“$26/month? A hell of a lot cheaper than cable TV.” Says one of the forum posters. He is right, but, of course, many will question the need to pay $26 for over 300 radio channels out of which 80% will probably never get listened to.
“Oh man! As a dual subscriber, this would be SO cool to have. Where do I sign up?” – on the other hand, of course, there are those people that don’t mind spending a little extra when they can get so much more.
“Cool idea if it ever comes to pass. Even though I only subscribe to Sirius, I would consider buying this with an eye on the future...” – for people such as this forum poster, the interoperable satellite radio system is the natural evolutionary step forward, so it is definitely worth looking into.

Implications of the interoperable satellite radio system
As you can see from the response of the potential customers, the interoperable satellite radio system is an interesting development. While Sirius and XM are lucky enough to be the only major players in this field, for now, it seems they are also ready to work together in order to consolidate their future. Of course, offering twice the programs on a single unit is a major step forward, and from the early stages it seems that the target audience is ready to receive the single receiver unit with applause. On the other hand, is this an initial enthusiastic response or is it genuine interest? Won’t 300+ channels become too much and won’t people start to feel like they are paying for something they are rarely using? There will also be some interesting things to follow as far as exclusivity rights go, because each of the two broadcasters have their own original approaches to common things. Another interesting aspect to follow will be how the sales for individual Sirius and XM units will go after the dual receiver hits the market. For many, the combined efforts of Sirius and XM tend to look like a first step towards a large scale joint venture that will lead to an absolute monopoly of the satellite radio market.

MLB to Disappear from Terrestrial Radio?

The changes that took place in the way MLB games were broadcast on television made many think that the same will happen to radio soon enough. Today, local television stations only broadcast 23% of the MLB games. Also, 7 of the major league team games are only available on cable, an exclusivity factor that seems to work well for them. In an interview to WSJ, Edison Media Research's President Larry Rosin declared that "it is probably inevitable that baseball radio broadcasts will go to a 100% subscription model... It will happen because there's too much money in it not to do it." This is an interesting perspective for the two main digital satellite radio providers, XM Satellite Radio and Sirius. This potential development sounds excellent for XM especially, as they would hold the exclusive rights to all major-league baseball games. Of course, that would be an important step forward for XM, as the MLB generates huge interest in the US, and it would mean that another building block has been added to the development of satellite radio.

MLB Radio and XM Radio

MLB also has its own subscription paid online radio channel, and if the same thing happens to radio as it did to television they would definitely enjoy the situation. Since experts in the communication field consider that satellite radio is still in its infancy, the trend of moving broadcasts of such games to a subscription paid environment would take digital radio broadcasting to the next level of development. The earnings from XM Radio and MLB Radio are split between the 30 MLB teams, but they are divided equally. This means that the MLB team’s interests would be high and the economical and financial factors could speed up the process of making MLB games exclusive to satellite radio. The statistics we have today tell an interesting story: presently around 23% of XM subscribers have signed up to receive the MLB transmission, so there is a lot of potential for growth. Terrestrial radio can already start to feel the danger of loosing MLB broadcasts to satellite radio as this revenue driven model is more attractive for the MLB teams.

Implications of such a transfer
As with anything that reaches such a controversial topic, the opinions are shared among experts and the general public. Some people are convinced that this whole movement is nothing more than a bubble of soap. Baseball is mostly a TV favorite and although there is still a lot of interest in MLB radio broadcasts, most people will not feel the transfer to digital radio as a major change. Although radio was the initial growing medium for baseball, television is king today, and they say that the transfer from terrestrial radio to satellite radio is not something that will have a significant impact.

Other opinions say that “MLB would loose more audience then it would gain from the exclusive fees”. Since the format of the terrestrial radio stations is more flexible it also allows them to broadcast more games than broadcast TV. The same people say that “the MLB would alienate a lot of local fans if they took baseball off AM radio”. For other people, there is another comparison to be made – that between the impact this would have on MLB and the impact it had on NFL, where a similar process has already started. The Sirius NFL broadcasts brought the company some new listeners, but the changes were not extreme and since NFL is more popular than MLB, some expect the same trend to be followed in MLBs case as well. Of course, there are voices that say this change would have a significant impact on the way baseball is perceived.

Since watching a game on TV can take away a few hours, many prefer to listen to the game on radio while they are doing something else. This is especially true during summer months, when many prefer to spend time in the yard or on the porch, not inside the room in front of a TV set. Of course, comparisons between the various major sport types in the US can be made from many perspectives, but most will agree that baseball is a game that can be followed on radio. For now, al the signs point at a transfer of broadcasts from terrestrial radio towards satellite radio, but this may change depending on the response companies and MLB receive from the public.
