Hopper (DVR)

Hopper (DVR) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hopper (DVR) rather than just read about it. In short: Hopper is a line of digital video recording (DVR) set-top boxes offered by the U.S. direct-broadcast satellite television provider Dish Network. First introduced at Consumer Electronics Show in January 2012, the Hopper was released in March 2012 as a component of the provider's whole-home DVR system, which networks the main Hopper unit with smaller "Joey" set-top boxes to form a client-server architecture.

Key takeaways

  • Hopper (DVR) belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hopper (DVR) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hopper (DVR) from memory before moving on to harder problems.

Reference excerpt

Hopper is a line of digital video recording (DVR) set-top boxes offered by the U.S. direct-broadcast satellite television provider Dish Network. First introduced at Consumer Electronics Show in January 2012, the Hopper was released in March 2012 as a component of the provider's whole-home DVR system, which networks the main Hopper unit with smaller "Joey" set-top boxes to form a client-server architecture. The Hopper is primarily distinguished by its "Primetime Anytime" functionality, which automatically records primetime programming off the four major U.S. television networks, while a later software update added "AutoHop", which allows commercials to automatically be removed from these recordings. The following year at the Consumer Electronics Show, Dish Network introduced an updated version known as Hopper with Sling, which integrates Slingbox place-shifting technology directly into the box. Both versions of the Hopper were met with universal praise by technology publications, particularly surrounding its "PrimeTime Anytime" functionality, the AutoHop feature, integration with smartphones and tablets, and the addition of built-in place-shifting to its second iteration. However, despite the positive reception, the Hopper became the subject of a copyright lawsuit filed by major U.S. broadcasters shortly after its release, who questioned the legality of the AutoHop feature by considering it to be an attack on their business model. Although unsuccessful in its lawsuits against Dish Network, ABC (Disney), CBS and Fox Broadcasting Company have since used carriage agreements and other settlements to impose requirements for AutoHop to be disabled on their respective primetime programs for a period after their original air date. The Hopper with Sling model was the subject of a related controversy when its "Best in Show" award at CES was vetoed by CBS—whose website CNET issued the award on behalf of CES organizers, because it was a party of active litigation with Dish Network. Due to the conflict of interest and its opinion of the device as being "pro-innovation and pro-consumer", CES organizers removed CNET from the "Best in Show" program, and reinstated the award. After a lawsuit which shut down Aereo (a service that allowed users to rent an antenna from a centralized location to watch over-the-air television online) as an unauthorized "public performance" of copyrighted television programming, Fox argued in court that the place-shifting functionality of Hopper with Sling was "virtually identical" and thus also a violation. However, its claim was rejected by the court.

Specifications

The Hopper is powered by a Broadcom 7420 system-on-chip, and contains a 2-terabyte hard drive; part of the drive is reserved for automatic recordings and video on demand content. The Hopper contains three satellite tuners, and can be networked with up to 3 smaller set-top boxes, known as a Joey, as clients for whole-home DVR access; they are attached to the main Hopper unit via coaxial cable. It also includes an Ethernet port, and eSATA and USB ports for attaching external storage. A Zigbee-based RF remote control is included. The Hopper with Sling model contains an upgraded Broadcom 7425 chip and built-in Wi-Fi, but is otherwise similar to the original model. In January 2014, Dish Network unveiled new "Super Joey" and wireless Joey units; the Super Joey contains two additional network ports, allowing users to record up to eight programs at once (four from the major networks, four from other channels). "Virtual Joey" apps were also unveiled for LG smart TVs, PlayStation 3 and PlayStation 4, which allow the devices to act as set-top boxes. In January 2015, Dish Network unveiled a 4K ultra HD Joey for release in mid-2015, which can stream 4K video from a Hopper downloaded via satellite, has the ability to display two HD channels at once picture-in-picture, and has a thin form factor designed to be mounted behind a television. Dish also unveiled a new simplified remote control for the Hopper featuring a clickable touchpad and a microphone for voice commands: upon its release, it became standard with new installations, and is purchasable as an add-on for existing systems. In January 2016, Dish Network unveiled Hopper 3, a new revision with upgraded hardware, USB 3.0 support, 16 tuners, and a new "Sports Bar Mode" that displays a grid of multiple channels at once on 4K televisions.

Worked examples

Example 1 — a first encounter with Hopper (DVR)

Start with the simplest possible case. Write down what Hopper (DVR) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hopper (DVR) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hopper (DVR) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hopper (DVR)

In research
Hopper (DVR) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hopper (DVR) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hopper (DVR) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audiovisual introductions in 2012, Digital video recorders, Dish Network, so understanding it makes those chapters shorter.
In everyday life
Look for Hopper (DVR) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
